Europa is one of the most promising places in our solar system to find an environment suitable for life beyond Earth. Evidence suggests that the ocean beneath Europa’s icy surface could contain the ingredients for life — water, the right chemistry, and energy. While Europa Clipper is not a life-detection mission, it will answer key questions about the moon’s potential habitability.
Europa Clipper’s launch period opens on Thursday, Oct. 10. The spacecraft, the largest NASA has ever built for a planetary mission, will launch on a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
Managed by Caltech in Pasadena, California, JPL leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, for NASA’s Science Mission Directorate in Washington. The main spacecraft body was designed by APL in collaboration with JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama, executes program management of the Europa Clipper mission. NASA’s Launch Services Program, based at Kennedy, manages the launch service for the Europa Clipper spacecraft.

Skywatching Skywatching Home Eclipses What’s Up Explore the Night Sky Night Sky Network More Tips and Guides FAQ 23 Min Read The Next Full Moon is a Partial Lunar Eclipse; a Supermoon; the Corn Moon; and the Harvest Moon
The Next Full Moon is a Partial Lunar Eclipse; a SuperMoon; the Corn Moon; the Harvest Moon; the Fruit or Barley Moon; the end of Ganesh Chaturthi and the start of Pitru Paksha; Madhu Purnima; the Mid-Autumn, Mooncake, or Reunion Festival Moon; Chuseok; and Imomeigetsu or the Potato Harvest Moon.
The full Moon will be Tuesday night, September 17, 2024, at 10:35 PM EDT. This will be on Wednesday from Newfoundland and Greenland Time eastward across Eurasia, Africa, and Australia to the International Date Line. Most commercial calendars will show this full Moon on Wednesday based on Greenwich or Universal Time. The Moon will appear full for about three days, from Monday evening through Thursday morning.
This will be a partial lunar eclipse. The Moon will start entering the Earth’s partial shadow at 8:41 PM EDT. The slight dimming of the Moon will be difficult to notice until the top edge of the Moon starts entering the full shadow at 10:13 PM. The peak of the eclipse will be at 10:44 PM with only the top 8 percent of the Moon in full shadow. The Moon will finish exiting the full shadow at 11:16 PM and the partial shadow on Wednesday morning at 12:47 AM.
The phases of the Moon for September 2024. NASA/JPL-Caltech This will be a supermoon. The term “supermoon” was coined by astrologer Richard Nolle in 1979 as either a new or full Moon that occurs when the Moon is within 90% of its closest to Earth. Since we can’t see new Moons, what has the public’s attention are full supermoons, the biggest and brightest Moons of the year. Although different publications use different thresholds for deciding which full Moons qualify, most agree this will be the second of four consecutive supermoons (effectively tied with the full Moon in October for the closest of the year).
The Maine Farmer’s Almanac first published “Indian” names for the full Moons in the 1930s and these names have become widely known and used. According to this almanac, as the full Moon in September the Algonquin tribes in what is now the northeastern USA called this the Corn Moon, as this was the time for gathering their main staple crops of corn, pumpkins, squash, beans, and wild rice.
As the full Moon closest to the autumnal equinox, this is the Harvest Moon. The first known written use of this name in the English language (per the Oxford English Dictionary) was in 1706. During the fall harvest season farmers sometimes need to work late into the night by moonlight. On average moonrise is about 50 minutes later each night. Around the Harvest Moon this time is shorter, about 25 minutes for the latitude of Washington, DC, and only 10 to 20 minutes farther north in Canada and Europe.
Other European names for this full Moon are the Fruit Moon, as a number of fruits ripen as the end of summer approaches, and the Barley Moon, from the harvesting and threshing of barley.
For Hindus, this full Moon marks the end of Ganesh Chaturthi and the start of Pitru Paksha. Ganesh Chaturthi (also called Vinayaka Chaturthi or Vinayaka Chavithi) is a 10 or 11 day festival honoring the god Ganesha that ends with this full Moon. Ganesha is easily recognized by his elephant head and is worshiped as the god of beginnings, wisdom, arts and sciences, and as the remover of obstacles. Throughout the festival celebrants offer food, sweets, and prayers to clay statues of Ganesha at home and on public stages. Traditions include chanting of Vedic hymns and Hindu texts, prayers, and fasting. On the last day (near the full Moon), people carry the statues to a nearby river or ocean and immerse them. As the clay dissolves, Ganesha is believed to return to his parents, the god Shiva and goddess Parvati, on Mount Kailash.
Pitru Paksha (fortnight of the ancestors) is a 15 days long festival that ends with the new Moon. During this time, Hindus honor their ancestors (pitrs) with rituals, food offerings, and scripture reading. Pitru Paksha is also known by a number of other names.
For some Buddhists in Bangladesh and Thailand this full Moon is Madhu Purnima, the Honey Full Moon Festival or the Honey-offering Festival. The legend is that when the Buddha was trying to bring peace between two factions in a forest, an elephant and a monkey fed him, with the elephant offering fruit and the monkey offering a honeycomb.
In China, Vietnam, and some other Asian countries, this full Moon corresponds with the Mid-Autumn Festival, a traditional harvest festival. In China, other names for this festival include the Moon Festival, the Mooncake Festival, and the Reunion Festival (with wives visiting their parents then returning to celebrate with their husbands and his parents). Part of the festival includes offerings to the Moon Goddess Chang’e (the name the China National Space Agency gives their lunar missions).
In Korea, this full Moon corresponds with the harvest festival Chuseok, during which Koreans return to their traditional hometowns to pay respect to the spirits of their ancestors.
This full Moon corresponds with the first of two Japanese Tsukimi or “Moon-Viewing” festivals, also called Imomeigetsu (which translates as “potato harvest Moon”) because of the tradition of offering sweet potatoes to the Moon. These festivities have become so popular that they are often extended for several days after the full Moon.
In many traditional Moon-based calendars the full Moons fall on or near the middle of each month. This full Moon is near the middle of the eighth month of the Chinese year of the Dragon and Rabi’ al-Awwal in the Islamic calendar, the month in which many Muslims celebrate Mawlid, the birth of the Prophet Muhammad. This full Moon is near the middle of Elul in the Hebrew calendar. Elul is a time of preparation for the High Holy Days of Rosh Hashanah and Yom Kippur. Customs include granting and asking others for forgiveness as well as beginning or ending all letters with the wish that the recipient will have a good year.
As usual, the wearing of suitably celebratory celestial attire is encouraged in honor of the full Moon. Go out and observe the Moon, enjoy this harvest season (including corn, fruit, and sweet potatoes, and honey), remember your ancestors, stay in touch with your parents, and forgive and ask forgiveness. Here’s wishing you a good year!
Comet C/2023 A3 (Tsuchinshan-ATLAS)
Pay attention to the news about Comet C/2023 A3 (Tsuchinshan-ATLAS)! There are a number of “ifs” so we don’t like to raise expectations. Similar visitors from the Oort Cloud have broken apart and fizzled out as they passed close to the Sun. If this comet survives its passage by the Sun (closest approach on September 27, 2024) and if the amount of gas and dust it gives off does not decrease significantly, this might be one of the best comets in a long time. If it strongly scatters sunlight towards the Earth it might even be visible in the glow of dusk just after its closest approach to Earth on October 12.
From the Washington, DC area and similar latitudes, this comet will be above the horizon before morning twilight begins from September 22 through October 4, with the current brightness curve predicting a steady increase in brightness from about visual magnitude 4 to near 3 (the smaller the number, the brighter the object). As it brightens it may be visible under dark sky conditions and even more impressive through binoculars or a telescope, although towards the start and end of this period it may be too low on the horizon to see when the sky is completely dark.
Between about October 4 and October 11 the Sun’s glare will mask visibility from the Northern Hemisphere. Check your local news or web sites for viewing information for your latitude. For example, Sky and Telescope reports that Southern Hemisphere skywatchers should fare better.
Comet C/2023 A3 (Tsuchinshan-ATLAS) will be at its closest to Earth on October 12 at 11:10 AM EDT. Around closest approach the comet’s brightness is predicted to peak at about visual magnitude 3 (similar to many stars). Forward scattering might increase the brightness significantly, possibly as high as -1 (brighter than every star except Sirius). How bright the comet actually appears will depend upon how much gas and dust it is giving off, which can change quickly. Also, brightness comparisons between comets and stars can be misleading as the light of the comet is spread out making it less distinct than a star with the same brightness.
The best time to look should be the evenings on and shortly after October 12 with the comet above the western horizon after sunset. The evening of October 12 the comet will be 4 degrees above the western horizon as evening twilight ends, similar in altitude and to the right of Venus. The comet is expected to dim as it moves away from the Earth, but will appear higher in a darker sky and set later each evening, which could make it easier to see. As evening twilight ends on October 13 it will be 10 degrees above the western horizon, 12 degrees on October 14, 16 degrees on October 15, etc. The brightness will decrease to about magnitude 6 by the end of October.
Meteor Showers
During this lunar cycle four minor meteors showers are predicted to peak at 5 or fewer visible meteors per hour (under ideal viewing conditions), making them basically not visible from our light-polluted urban areas.
Evening Sky Highlights
On the evening of Tuesday, September 17 (the evening of the full Moon), as twilight ends (at 8:10 PM EDT), the rising Moon will be 11 degrees above the east-southeastern horizon with Saturn to the upper right at 14 degrees above the horizon. Later in the evening the partial shadow of the Earth will cover a small upper part of the Moon. Bright Venus will be 2 degrees above the west-southwestern horizon with the star Spica on the horizon to the lower left. The bright star closest to overhead will be Vega, the brightest star in the constellation Lyra the lyre, at 87 degrees above the western horizon. Vega is part of the Summer Triangle along with Deneb and Altair. It is the 5th brightest star in our night sky, about 25 light-years from Earth, has twice the mass of our Sun, and shines 40 times brighter than our Sun.
As this lunar cycle progresses, Saturn and the background of stars will appear to shift westward each evening (as the Earth moves around the Sun). Bright Venus will shift to the left along the west-southwestern horizon, appearing slightly higher each evening. The waxing Moon will pass by Venus on October 5, Antares on October 7, and Saturn on October 14. Comet C/2023 A3 (Tsuchinshan-ATLAS) will be at its closest to Earth on October 12 at 11:10 AM. Assuming it survives its pass by the Sun on September 27 and depending upon how much gas and dust it gives off, it could be a good show in the evenings on and after October 12. See the comet summary above and keep an eye on the news for updates on this comet.
By the evening of Thursday, October 17 (the evening of the full Moon after next), as twilight ends (at 7:24 PM EDT), the rising Moon will be 9 degrees above the eastern horizon. Saturn will be 27 degrees above the southeastern horizon. Bright Venus will be 6 degrees above the west-southwestern horizon. Comet C/2023 A3 (Tsuchinshan-ATLAS) will be 22 degrees above the western horizon. The bright star closest to overhead will be Deneb at 80 degrees above the northeastern horizon. Deneb is the 19th brightest star in our night sky and is the brightest star in the constellation Cygnus the swan. Deneb is one of the three bright stars of the “Summer Triangle” (along with Vega and Altair). Deneb is about 20 times more massive than our Sun but has used up its hydrogen, becoming a blue-white supergiant about 200 times the diameter of the Sun. If Deneb were where our Sun is, it would extend to about the orbit of the Earth. Deneb is about 2,600 light years from us.
Morning Sky Highlights
On the morning of Wednesday, September 18 (the morning of the night of the full Moon), as twilight begins (at 5:55 AM EDT), the setting full Moon will be 15 degrees above the west-southwestern horizon. The brightest planet in the sky will be Jupiter at 71 degrees above the south-south eastern horizon. Near Jupiter will be Mars at 61 degrees above the east-southeastern horizon. Saturn will be below the Moon at 1 degree above the western horizon. The bright star appearing closest to overhead will be Capella, the brightest star in the constellation Auriga the charioteer, at 80 degrees above the northeastern horizon. Although we see Capella as a single star (the 6th brightest in our night sky), it is actually four stars (two pairs of stars orbiting each other). Capella is about 43 lightyears from us.
As this lunar cycle progresses, Jupiter, Mars, Saturn, and the background of stars will appear to shift westward each evening. After September 19 Saturn set before morning twilight begins. The waning Moon will pass by the Pleiades star cluster on September 22, Mars on September 25, Pollux on September 26, and Regulus on September 29. Comet C/2023 A3 (Tsuchinshan-ATLAS) will be above the horizon before morning twilight begins from September 22 through October 4. Comets are notoriously difficult to predict, but if the amount of gas and dust it gives off remains constant it should increase in brightness each morning. See the comet summary above and keep an eye on the news for updates on this comet.
By the morning of Thursday, October 17 (the morning of the full Moon after next), as twilight begins (at 6:22 AM EDT), the setting full Moon will be 11 degrees above the western horizon. The brightest planet in the sky will be Jupiter at 63 degrees above the west-southwestern horizon. Mars will be at 72 degrees above the south-southeastern horizon. The bright star appearing closest to overhead will be Pollux, the 17th brightest star in our night sky and the brighter of the twin stars in the constellation Gemini, at 75 degrees above the southeastern horizon. Pollux is an orange tinted star about 34 lightyears from Earth. It is not quite twice the mass of our Sun but about 9 times the diameter and 33 times the brightness.
Detailed Daily Guide
Here for your reference is a day-by-day listing of celestial events between now and the full Moon on October 17, 2024. The times and angles are based on the location of NASA Headquarters in Washington, DC, and some of these details may differ for where you are (I use parentheses to indicate times specific to the DC area). If your latitude is significantly different than 39 degrees north (and especially for my Southern Hemisphere readers), I recommend using an astronomy app or a star-watching guide from a local observatory, news outlet, or astronomy club.
Saturday night, September 14, is International Observe the Moon Night! See https://moon.nasa.gov/observe-the-moon-night/about/overview/ for more information.
Our 24 hour clock is based on the average length of the solar day. Solar noon on Sunday, September 15 to solar noon on Monday, September 16, will be the shortest solar day of the year, 23 hours, 59 minutes, and 38.6 seconds long.
Monday night into Tuesday morning, September 16 to 17, Saturn will appear near the full Moon. As evening twilight ends (at 8:12 PM EDT) Saturn will be 6 degrees to the left of the Moon. When the Moon reaches its highest for the night (at 12:17 AM) Saturn will be 4 degrees to the upper left. By the time morning twilight begins (at 5:54 AM) the Moon will be 1 degree above the west-southwestern horizon with Saturn 1 degree above the Moon. For parts of western North America and across the Pacific Ocean towards Australia the Moon will pass in front of Saturn. See http://lunar-occultations.com/iota/planets/0917saturn.htm for a map and information on the areas that will see this occultation.
Tuesday morning, September 17, will be the last morning that Mercury will be above the horizon as morning twilight begins (at 5:54 AM EDT).
As mentioned above, the full Moon will be Tuesday night, September 17, at 10:35 PM EDT. This will be on Wednesday from Newfoundland and Greenland Time eastward across Eurasia, Africa, and Australia to the International Date Line. Most commercial calendars are based on Greenwich or Universal Time and will show this full Moon on Wednesday. The Moon will appear full for about three days from Monday evening through Thursday morning.
This will be a partial lunar eclipse. The Moon will start entering the partial shadow of the Earth at 8:41 PM EDT. The slight dimming of the Moon will be difficult to notice until the top edge of the Moon starts entering the full shadow at 10:13 PM. The peak of the eclipse will be at 10:44 PM with just the top 8.4% of the Moon in full shadow. The Moon will finish exiting the full shadow at 11:16 PM and the partial shadow on Wednesday morning at 12:47 AM.
This will be the second of four consecutive supermoons, appearing larger than last month’s supermoon and effectively tied with the full Moon in October for the closest full Moon of the year.
Tuesday and Wednesday evenings, September 17 and 18, the star Spica will appear a little over 2 degrees from the bright planet Venus. On Tuesday evening as evening twilight ends (at 8:10 PM EDT) Spica will be to the lower left of Venus and on the verge of setting on the west-southwestern horizon. Wednesday evening Spica will be a few hundredths of a degree closer and will appear below Venus, but will set about 2 minutes before evening twilight ends.
Wednesday morning September 18, at 9:29 AM EDT, the Moon will be at perigee, its closest to the Earth for this orbit.
Thursday morning, September 19, will be the last morning the planet Saturn will be above the western horizon as morning twilight begins.
If you are interested in spotting the planet Neptune through a telescope, Friday evening, September 20, will be when it will be at its closest and brightest for the year. Neptune will reach its highest in the sky early Saturday morning (at 1:02 AM EDT).
Saturday night into Sunday morning, September 21 to 22, the Pleiades star cluster will appear near the waning gibbous Moon. The Pleiades will be 5 degrees to the lower left as they rise on the east-northeastern horizon (at 9:23 PM EDT), 1.5 degrees to the upper left by the time the Moon reaches its highest for the night (at 4:44 AM), and less than 1 degree to the upper left as morning twilight begins (at 5:59 AM). The Moon will actually pass through the Pleiades (at about 8 AM) when daylight will mask these stars from view.
Sunday morning, September 22, will be the first morning Comet C/2023 A3 (Tsuchinshan-ATLAS) will be above the horizon before morning twilight begins, with the current brightness curve predicting it at visual magnitude 4. Unless it breaks apart, this comet is likely to brighten each morning until October 4 (after which it will no longer be above the horizon before twilight begins).
Sunday morning, September 22, at 8:44 AM EDT, will be the autumnal equinox, the astronomical end of summer and start of fall.
Monday night into Tuesday morning, September 23 to 24, the bright planet Jupiter will appear to the lower right of the waning half-full Moon. Jupiter will be 6 degrees to the lower right as it rises on the east-northeastern horizon (at 10:54 PM EDT). Jupiter will shift slightly clockwise as it moves away from the Moon.
Thursday afternoon, September 24, the waning Moon will appear half-full as it reaches its last quarter at 2:50 PM EDT (when we can’t see it).
Wednesday morning, September 25, the planet Mars will appear below the waning crescent Moon. Mars will be 6 degrees below the Moon as it rises on the east-northeastern horizon (at 12:16 AM EDT). Mars will be 5 degrees to the lower right as morning twilight begins (at 6:01 AM).
Thursday morning, September 26, the star Pollux (the brighter of the twin stars in the constellation Gemini the twins) will appear near the waning crescent Moon. Pollux will be 3 degrees to the lower left as it rises on the northeastern horizon (at 12:47 AM EDT) and will be 2 degrees to the upper left by the time morning twilight begins (at 6:02 AM).
Friday afternoon, September 27, at around 2 PM EDT, Comet C/2023 A3 (Tsuchinshan-ATLAS) will be at its closest to the Sun. This comet has an inbound orbital period of millions of years and may gain enough energy from this flyby of the Sun to leave the solar system forever.
Sunday morning, September 29, the star Regulus will appear near the waning crescent Moon. As Regulus rises on the east-northeastern horizon (at 4:01 AM EDT) it will be 2.5 degrees to the lower right of the Moon. Morning twilight will begin 2 hours later (at 6:05 AM) with Regulus 3 degrees to the right.
Monday afternoon, September 30, the planet Mercury will be passing on the far side of the Sun as seen from the Earth, called superior conjunction. Because Mercury orbits inside of the orbit of Earth, it will be shifting from the morning sky to the evening sky and will begin emerging from the glow of twilight on the west-southwestern horizon towards the end of October (depending upon viewing conditions).
Wednesday, October 2, at 2:46 PM EDT, will be the new Moon, when the Moon passes between the Earth and the Sun and is usually not visible. For much of the Pacific Ocean as well as the southern part of South America, part of Antarctica, and a thin slice of the southwestern Atlantic, the Moon will block some of the Sun in a partial eclipse. For a narrow strip from the Pacific south of the Hawaiian Islands across the Pacific, part of Chile and Argentina, and into the southwestern Atlantic Ocean, the Moon will actually pass in front of the Sun, blocking most of it from view in an annular solar eclipse. Because the Moon will be at apogee (its farthest from the Earth) just 70 minutes later (at 3:56 PM) it will not block the entire Sun from view and this will not be a total solar eclipse.
The day of or the day after the New Moon marks the start of the new month for most lunisolar calendars. Sundown on Wednesday, October 2, will be the start of Rosh Hashanah (the Head of the Year), the two-day Jewish New Year celebration that will end at sundown on Friday, October 4. Rosh Hashanah is the first of a series of holidays in Tishrei, the first month of the Hebrew calendar. The tenth day of Tishrei is Yom Kippur, the Day of Atonement. The 10 days from Rosh Hashanah to Yom Kippur, called the Days of Awe, are a time to reflect on the mistakes of the past year and make resolutions for the new year. The fifteenth day of Tishrei (close to the full Moon after next) is the start of the 7-day Sukkot holiday.
The ninth month of the Chinese year of the Dragon starts on Thursday, October 3.
In the Islamic calendar the months traditionally start with the first sighting of the waxing crescent Moon. Many Muslim communities now follow the Umm al-Qura Calendar of Saudi Arabia, which uses astronomical calculations to start months in a more predictable way. Using this calendar, sundown on Thursday evening, October 3, will probably mark the beginning of Rabiʽ al-Thani, also known as Rabi’ al-Akhirah.
Friday, October 4, will be the last morning Comet C/2023 A3 (Tsuchinshan-ATLAS) will be above the horizon before morning twilight begins, with the current brightness curve predicting a visual magnitude near 3, similar in brightness to many visible stars. It may be visible to the naked eye under dark sky conditions and even more impressive through binoculars or a telescope.
Saturday evening, October 5, you may be able to see the thin waxing crescent Moon 4.5 degrees to the lower left of the bright planet Venus. As evening twilight ends (at 7:41 PM EDT) the Moon will be a degree above the west-southwestern horizon. The Moon will set first 14 minutes later (at 7:55 PM).
Monday evening, October 7, the bright star Antares will appear 2 degrees to the right of the waxing crescent Moon. As evening twilight ends (at 7:38 PM EDT) the Moon will be 11 degrees above the southwestern horizon. Antares will set first about 20 minutes later (at 9 PM).
Thursday afternoon, October 10, the Moon will appear half-full as it reaches its first quarter at 2:55 PM EDT.
Saturday morning, October 12, at 11:10 AM, Comet C/2023 A3 (Tsuchinshan-ATLAS) will be at its closest to Earth. If it survives its pass by the Sun this will likely be when it will be near its brightest. Although it will be on the horizon as evening twilight ends on Friday, our first chance to see it above the horizon as it emerges from the glow of dusk likely will be Saturday evening, when the comet will be 4 degrees above the western horizon as evening twilight ends (at 7:31 PM EDT), similar in altitude and to the right of Venus. Over the next few nights the comet will likely dim as it moves away from the Earth, but also appear higher in the sky and set later each evening, giving us more time and darker skies to look for this comet. As evening twilight ends on October 13 it will be 10 degrees above the western horizon, 12 degrees on October 14, 16 degrees on October 15, etc. Current brightness curves predict it will dim quickly and will be below magnitude 6 by the end of October. How bright the comet will be and how quickly it actually dims will depend upon the gas and dust it is giving off, which can vary quickly and unpredictably, but it could be a good show in the evenings after October 12.
Monday evening, October 14, the planet Saturn will appear near the waxing gibbous Moon. As evening twilight ends (at 7:28 PM EDT) Saturn will be 4 degrees to the upper right. The Moon will reach its highest for the night about 3.5 hours later (at 10:53 PM) with Saturn 5 degrees to the lower right. The pair will continue to separate, with Saturn setting first 5 hours after that (at 4:09 AM). For parts of Southern Asia and Africa the Moon will block Saturn from view, see http://lunar-occultations.com/iota/planets/1014saturn.htm for a map and information on the areas that will acually see this occultation.
Wednesday evening, October 16, at 8:57 PM EDT, the Moon will be at perigee, its closest to the Earth for this orbit.
The full Moon after next will be Thursday morning, October 17, 2024, at 7:26 AM EDT. This will be late Wednesday night in the International Date Line West time zone and early Friday morning from New Zealand Time eastwards to the International Date Line. This will be the third of four consecutive supermoons (and the brightest by a tiny margin). The Moon will appear full for about 3 days around this time, from Tuesday evening through Friday morning.

5 Min Read 9 Phenomena NASA Astronauts Will Encounter at Moon’s South Pole
An artist’s rendering of an Artemis astronaut working on the Moon’s surface. Credits:
NASA NASA’s Artemis campaign will send the first woman and the first person of color to the Moon’s south polar region, marking humanity’s first return to the lunar surface in more than 50 years.
Here are some out-of-this-world phenomena Artemis astronauts will experience:
1. A Hovering Sun and Giant Shadows
This visualization shows the motions of Earth and the Sun as viewed from the South Pole of the Moon.
NASA’s Goddard Space Flight Center Near the Moon’s South Pole, astronauts will see dramatic shadows that are 25 to 50 times longer than the objects casting them. Why? Because the Sun strikes the surface there at a low angle, hanging just a few degrees above the horizon. As a result, astronauts won’t see the Sun rise and set. Instead, they’ll watch it hover near the horizon as it moves horizontally across the sky.
2. Sticky, Razor-Sharp Dust …
This dust particle came from a lunar regolith sample brought to Earth in 1969 by Apollo 11 astronauts. The particle is about 25 microns across, less than the width of an average human hair. The image was taken with a scanning electron microscope. The lunar dust, called regolith, that coats the Moon’s surface looks fine and soft like baking powder. But looks can be deceiving. Lunar regolith is formed when meteoroids hit the Moon’s surface, melting and shattering rocks into tiny, sharp pieces. The Moon doesn’t have moving water or wind to smooth out the regolith grains, so they stay sharp and scratchy, posing a risk to astronauts and their equipment.
3. … That’s Charged with Static Electricity
Astronaut Eugene Cernan, commander of Apollo 17, inside the lunar module on the Moon after his second moonwalk of the mission in 1972. His spacesuit and face are covered in lunar dust. Because the Moon has no atmosphere to speak of, its surface is exposed to plasma and radiation from the Sun. As a result, static electricity builds up on the surface, as it does when you shuffle your feet against a carpeted floor. When you then touch something, you transfer that charge via a small shock. On the Moon, this transfer can short-circuit electronics. Moon dust also can make its way into astronaut living quarters, as the static electricity causes it to easily stick to spacesuits. NASA has developed methods to keep the dust at bay using resistant textiles, filters, and a shield that employs an electric field to remove dust from surfaces.
4. A New Sense of Lightness
In 1972, Apollo 16 astronaut Charles Duke hammered a core tube into the Moon’s surface until it met a rock and wouldn’t go any farther. Then the hammer flew from his hand. He made four attempts to pick it up by bending down and leaning to reach for it. He gave up and returned to the rover to get tongs to finally pick up the hammer successfully.
NASA’s Johnson Space Center Artemis moonwalkers will have a bounce to their step as they traverse the lunar surface. This is because gravity won’t pull them down as forcefully as it does on Earth. The Moon is only a quarter of Earth’s size, with six times less gravity. Simple activities, like swinging a rock hammer to chip off samples, will feel different. While a hammer will feel lighter to hold, its inertia won’t change, leading to a strange sensation for astronauts. Lower gravity has perks, too. Astronauts won’t be weighed down by their hefty spacesuits as much as they would be on Earth. Plus, bouncing on the Moon is just plain fun.

The person is demonstrating an activity that helps people learn about the phases of the Moon by acting them out. NASA’s Jet Propulsion Laboratory When Artemis astronauts look at the sky from the Moon, they’ll see their home planet shining back at them. Just like Earthlings see different phases of the Moon throughout a month, astronauts will see an ever-shifting Earth. Earth phases occur opposite to Moon phases: When Earth experiences a new Moon, a full Earth is visible from the Moon.
6. An Itty-Bitty Horizon
A view from the Apollo 11 spacecraft in July 1969 shows Earth rising above the Moon’s horizon. NASA Because the Moon is smaller than Earth, its horizon will look shorter and closer. To someone standing on a level Earth surface, the horizon is 3 miles away, but to astronauts on the Moon, it’ll be only 1.5 miles away, making their surroundings seem confined.
7. Out-of-This-World Temperatures
This graphic shows maximum summer and winter temperatures near the lunar South Pole. Purple, blue, and green identify cold regions, while yellow to red signify warmer ones. The graphic incorporates 10 years of data from NASA’s LRO (Lunar Reconnaissance Orbiter), which has been orbiting the Moon since 2009.
NASA/LRO Diviner Seasonal Polar Data Because sunlight at the Moon’s South Pole skims the surface horizontally, it brushes crater rims, but doesn’t always reach their floors. Some deep craters haven’t seen the light of day for billions of years, so temperatures there can dip to minus 334 F. That’s nearly three times colder than the lowest temperature recorded in Antarctica. At the other extreme, areas in direct sunlight, such as crater rims, can reach temperatures of 130 F.

NASA’s Scientific Visualization Studio Artemis moonwalkers will find a rugged landscape that takes skill to traverse. The Moon has mountains, valleys, and canyons, but its most notable feature for astronauts on the surface may be its millions of craters. Near the South Pole, gaping craters and long shadows will make it difficult for astronauts to navigate. But, with training and special gear, astronauts will be prepared to meet the challenge.

On Sept. 10, 2009, the Japan Aerospace Exploration Agency (JAXA) launched its first cargo delivery spacecraft, the H-II Transfer Vehicle-1 (HTV-1), to the International Space Station. The HTV cargo vehicles, also called Kounotori, meaning white stork in Japanese, not only maintained the Japanese Experiment Module Kibo but also resupplied the space station in general with pressurized and unpressurized cargo and payloads. Following its rendezvous with the space station, Expedition 20 astronauts grappled and berthed HTV-1 on Sept. 17, and spent the next month transferring its 9,900 pounds of internal and external cargo to the space station and filling the HTV-1 with trash and unneeded equipment. They released the craft on Oct. 30 and ground controllers commanded it to a destructive reentry on Nov. 1.
Left and middle: Two views of the HTV-1 Kounotori cargo spacecraft during prelaunch processing at the Tanegashima Space Center in Japan. Right: Schematic illustration showing the HTV’s major components. Image credits: courtesy JAXA.
The HTV formed part of a fleet of cargo vehicles that at the time included NASA’s space shuttle until its retirement in 2011, Roscosmos’ Progress, and the European Space Agency’s (ESA) Automated Transfer Vehicle that flew five missions between 2008 and 2015. The SpaceX Cargo Dragon and Orbital (later Northrup Grumman) Cygnus commercial cargo vehicles supplemented the fleet starting in 2012 and 2013, respectively. The HTV weighed 23,000 pounds empty and could carry up to 13,000 pounds of cargo, although on this first flight carried only 9,900 pounds. The vehicle included both a pressurized and an unpressurized logistics carrier. Following its rendezvous with the space station, it approached to within 33 feet, at which point astronauts grappled it with the station’s robotic arm and berthed it to the Harmony Node 2 module’s Earth facing port. Space station managers added two flights to the originally planned seven, with the last HTV flying in 2020. An upgraded HTV-X vehicle will soon make its debut to carry cargo to the space station, incorporating the lessons learned from the nine-mission HTV program.

Prelaunch processing of HTV-1 took place at the Tanegashima Space Center, where engineers inspected and assembled the spacecraft’s components. Workers installed the internal cargo into the pressurized logistics carrier and external payloads onto the External Pallet that they installed into the unpressurized logistics carrier. HTV-1 carried two external payloads, the Japanese Superconducting submillimeter-wave Limb Emission Sounder (SMILES) and the U.S. Hyperspectral Imager for Coastal Ocean (HICO)-Remote Atmospheric and Ionospheric detection System (RAIDS) Experiment Payload (HREP). On Aug. 23, 2009, workers encapsulated the assembled HTV into its payload shroud and a week later moved it into the Vehicle Assembly Building (VAB), where they mounted it atop the H-IIB rocket. Rollout from the VAB to the pad took place on the day of launch.

On Sept. 10 – Sept. 11 Japan time – HTV-1 lifted off its pad at Tanegashima on the maiden flight of the H-IIB rocket. Controllers in Tanegashima’s launch control center monitored the flight until HTV-1 separated from the booster’s second stage. At that point, HTV-1 automatically activated its systems and established communications with NASA’s Tracking and Data Relay Satellite System. Control of the flight shifted to the mission control room at the Tsukuba Space Center outside Tokyo. Controllers in the Mission Control Center at NASA’s Johnson Space Center in Houston also monitored the mission’s progress.

Right: European Space Agency astronaut Frank DeWinne, left, Stott, and Canadian Space Agency astronaut Robert Thirsk in the Destiny module following the robotic operations to capture and berth HTV-1.
Following several days of systems checks, HTV-1 approached the space station on Sept. 17. Members of Expedition 20 monitored its approach, as it stopped within 33 feet of the orbiting laboratory. Using the space station’s Canadarm2 robotic arm, Expedition 20 Flight Engineer and NASA astronaut Nicole P. Stott grappled HTV-1. Fellow crew member Canadian Space Agency astronaut Robert Thirsk berthed the vehicle on the Harmony Node 2 module’s Earth-facing port. The following day, the Expedition 20 crew opened the hatch to HTV-1 to begin the cargo transfers.

Over the next several weeks, the Expedition 20 and 21 crews transferred more than 7,900 pounds of cargo from the pressurized logistics carrier to the space station. The items included food, science experiments, robotic arm and other hardware for the Kibo module, crew supplies including clothing, toiletries, and personal items, fluorescent lights, and other supplies. They then loaded the module with trash and unneeded equipment, altogether weighing 3,580 pounds.

Working as a team, NASA astronauts Stott and Michael R. Barratt along with Thirsk and ESA astronaut Frank DeWinne performed the transfer of the external payloads. On Sept. 23, using the station’s robotic arm, they grappled the Exposed Pallet (EP) and removed it from HTV-1’s unpressurized logistics carrier, handing it off to the Japanese remote manipulator system arm that temporarily stowed it on the JEM’s Exposed Facility (JEM-EF). The next day, using the Japanese arm, DeWinne and Stott transferred the SMILES and HREP experiments to their designated locations on the JEM-EF. On Sept. 25, they grappled the now empty EP and placed it back into HTV-1’s unpressurized logistics carrier.

Following completion of all the transfers, Expedition 21 astronauts aboard the space station closed the hatch to HTV-1 on Oct. 29. The next day, Stott and DeWinne grappled the vehicle and unberthed it from Node 2. While passing over the Pacific Ocean, they released HTV-1 and it began its departure maneuvers from the station. On Nov. 1, the flight control team in Tsukuba sent commands to HTV-1 to execute three deorbit burns. The vehicle reentered the Earth’s atmosphere, burning up off the coast of New Zealand, having completed the highly successful 52-day first HTV resupply mission. Eight more HTV missions followed, all successful, with HTV-9 completing its mission in August 2020.

On Sept. 9, 1994, space shuttle Discovery took to the skies on its 19th trip into space. During their 11-day mission, the STS-64 crew of Commander Richard “Dick” N. Richards, Pilot L. Blaine Hammond, and Mission Specialists Jerry M. Linenger, Susan J. Helms, Carl J. Meade, and Mark C. Lee demonstrated many of the space shuttle’s capabilities. They used a laser instrument to observe the Earth’s atmosphere, deployed and retrieved a science satellite, and used the shuttle’s robotic arm for a variety of tasks, including studying the orbiter itself. During a spacewalk, Lee and Meade tested a new device to rescue astronauts who found themselves detached from the vehicle. Astronauts today use the device routinely for spacewalks from the International Space Station.

In November 1993, NASA announced the five-person all-veteran STS-64 crew. Richards, selected as an astronaut in 1980, had made three previous spaceflights, STS-28, STS-41, and STS-50. Lee, a member of the astronaut class of 1984, had two flights to his credit, STS-30 and STS-47, as did Meade, selected in 1985 and a veteran of STS-38 and STS-50. Each making their second trip into space, Hammond, selected in 1984 had flown on STS-39, and Helms, from the class of 1990 had flown on STS-54. In February 1994, NASA added first time space flyer Linenger to the crew, partly to make him eligible for a flight to Mir. He holds the distinction as the first member of his astronaut class of 1992 to fly in space.

Discovery returned to NASA’s Kennedy Space Center (KSC) in Florida following its previous flight, the STS-60 mission, in February 1994. Workers in KSC’s Orbiter Processing Facility (OPF) removed the previous payload and began to service the orbiter. On May 26, workers moved Discovery into the Vehicle Assembly Building for temporary storage to make room in the OPF for Atlantis, just returned from Palmdale, California, where it underwent modifications to enable extended duration flights and dockings with space stations. Discovery returned to the OPF for payload installation in July, and rolled back to the VAB on Aug. 11 for mating with its external tank and solid rocket boosters. Discovery rolled out to Launch Pad 39B on Aug. 19, with its sister ship Endeavour still on Launch Pad 39A following the previous day’s launch abort. The six-person crew traveled to KSC to participate in the Terminal Countdown Demonstration Test, essentially a dress rehearsal for the launch countdown, on Aug. 24.
Liftoff of Discovery on the STS-64 mission.
On Sept. 9, 1994, after a more than two-hour delay caused by inclement weather, Discovery thundered into the sky to begin the STS-64 mission. Eight and a half minutes later, the orbiter and its crew reached space, and with a firing of the shuttle’s Orbiter Maneuvering System (OMS) engines they entered a 160-mile orbit inclined 57 degrees to the equator, ideal for Earth and atmospheric observations. The crew opened the payload bay doors, deploying the shuttle’s radiators, and removed their bulky launch and entry suits, stowing them for the remainder of the flight. They began to convert their vehicle into a science platform.

One of the primary payloads on STS-64, the LIDAR (light detection and ranging) In-space Technology Experiment (LITE), mounted in Discovery’s forward payload bay, made the first use of a laser to study Earth’s atmosphere, cloud cover, and airborne dust from space. Lee, with help from Richards and Meade, activated LITE, built at NASA’s Langley Research Center in Hampton, Virginia, on the flight’s first day. The experiment operated for 53 hours during the mission, gathering 43 hours of high-rate data shared with 65 groups in 20 countries.

The Shuttle Plume Impingement Flight Experiment (SPIFEX), built at NASA’s Johnson Space Center (JSC) in Houston, consisted of a package of instruments positioned on the end of a 33-foot boom, to characterize the behavior of the shuttle’s Reaction Control System (RCS) thrusters. On the flight’s second day, Helms used the shuttle’s Remote Manipulator System (RMS), or robotic arm, to pick up SPIFEX. Over the course of the mission, she, Lee, and Hammond took turns operating the arm to obtain 100 test points during various thruster firings. A video camera on SPIFEX returned images of Discovery from several unusual angles.

Middle: Discovery approaches SPARTAN during the rendezvous. Right: Astronaut Susan J. Helms operating the Shuttle’s Remote Manipulator System prepares to grapple SPARTAN.
On the mission’s fifth day, Helms used the RMS to lift the Shuttle Pointed Autonomous Research Tool for Astronomy-201 (SPARTAN-201) satellite out of the payload bay and released it. Two and a half minutes later, SPARTAN activated itself, and Richards maneuvered Discovery away from the satellite so it could begin its science mission. On flight day seven, Discovery began its rendezvous with SPARTAN, and Hammond flew the shuttle close enough for Helms to grapple it with the arm and place it back in the payload bay. During its two-day free flight, SPARTAN’s two telescopes studied the acceleration and velocity of the solar wind and measured aspects of the Sun’s corona or outer atmosphere.

On flight day seven, in preparation for the following day’s spacewalk, the astronauts lowered the pressure in the shuttle from 14.7 pounds per square inch (psi) to 10.2 psi to reduce the likelihood of the spacewalkers, Lee and Meade, from developing decompression sickness, also known as the bends. As an added measure, the two spent 15 minutes breathing pure oxygen before donning their spacesuits and exiting the shuttle’s airlock.

Meade tests the SAFER during an untethered spacewalk. Right: Meade, left, tests the ability of the SAFER to stop his spinning as Lee looks on.
The main tasks of the spacewalk involved testing the Simplified Aid for EVA (Extravehicular Activity) Rescue (SAFER), a device designed at JSC that attaches to the spacesuit’s Portable Life Support System backpack. The SAFER contains nitrogen jets that an astronaut can use, should he or she become untethered, to fly back to the vehicle, either the space shuttle or the space station. The two put the SAFER through a series of tests, including a familiarization, a system engineering evaluation, a crew rescue evaluation, and a precision flight evaluation. During the tests, Lee and Meade remained untethered from the shuttle, the first untethered spacewalk since STS-51A in November 1984. Lee and Meade successfully completed all the tests and gave the SAFER high marks. Astronauts conducting spacewalks from the space station use the SAFER as a standard safety device. Following the 6-hour 51-minute spacewalk, the astronauts raised the shuttle’s atmosphere back to 14.7 psi.

Like on all space missions, the STS-64 astronauts spent their spare time looking out the window. They took numerous photographs of the Earth, their high inclination orbit allowing them views of parts of the planet not seen during typical shuttle missions.

Mission managers had extended the original flight duration by one day for additional data collection for the various payloads. On the planned reentry day, Sept. 19, bad weather at KSC forced the crew to spend an additional day in space. The next day, continuing inclement weather caused them to wave off the first two landing attempts at KSC and diverted to Edwards Air Force Base (AFB) in California.
Left: Richard Richards brings Discovery home at California’s Edwards Air Force Base. Middle: Workers at Edwards safe Discovery after its return from STS-64. Right: Discovery takes off from Edwards atop a Shuttle Carrier Aircraft for the ferry flight to NASA’s Kennedy Space Center in Florida.
On Sept. 20, they closed Discovery’s payload bay doors, donned their launch and entry suits, and strapped themselves into their seats for entry and landing. They fired Discover’s OMS engines to drop them out of orbit. Richards piloted Discovery to a smooth landing at Edwards, ending the 10-day 22-hour 50-minute flight. The crew had orbited the Earth 176 times. Workers at Edwards safed the vehicle and placed it atop a Shuttle Carrier Aircraft for the ferry flight back to KSC. The duo left Edwards on Sept. 26, and after an overnight stop at Kelly AFB in San Antonio, arrived at KSC the next day. Workers there began preparing Discovery for its next flight, the STS-63 Mir rendezvous mission, in February 1995.
