Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s SPHEREx mission is observing the entire sky in 102 infrared colors, or wavelengths of light not visible to the human eye. This image shows a section of sky in one wavelength (3.29 microns), revealing a cloud of dust made of a molecule similar to soot or smoke.NASA/JPL-Caltech This image from NASA’s SPHEREx shows the same region of space in a different infrared wavelength (0.98 microns), but the dust cloud is no longer visible. The molecules that compose the dust — polycyclic aromatic hydrocarbons — do not radiate light in this color.NASA/JPL-Caltech After weeks of preparation, the space observatory has begun its science mission, taking about 3,600 unique images per day to create a map of the cosmos like no other.
Launched on March 11, NASA’s SPHEREx space observatory has spent the last six weeks undergoing checkouts, calibrations, and other activities to ensure it is working as it should. Now it’s mapping the entire sky — not just a large part of it — to chart the positions of hundreds of millions of galaxies in 3D to answer some big questions about the universe. On May 1, the spacecraft began regular science operations, which consist of taking about 3,600 images per day for the next two years to provide new insights about the origins of the universe, galaxies, and the ingredients for life in the Milky Way.
This video shows SPHEREx’s field of view as it scans across one section of sky inside the Large Magellanic Cloud, with rainbow colors representing the infrared wavelengths the telescope’s detectors see. The view from one detector array moves from purple to green, followed by the second array’s view, which changes from yellow to red. The images are looped four times. NASA/JPL-Caltech “Thanks to the hard work of teams across NASA, industry, and academia that built this mission, SPHEREx is operating just as we’d expected and will produce maps of the full sky unlike any we’ve had before,” said Shawn Domagal-Goldman, acting director of the Astrophysics Division at NASA Headquarters in Washington. “This new observatory is adding to the suite of space-based astrophysics survey missions leading up to the launch of NASA’s Nancy Grace Roman Space Telescope. Together with these other missions, SPHEREx will play a key role in answering the big questions about the universe we tackle at NASA every day.”
From its perch in Earth orbit, SPHEREx peers into the darkness, pointing away from the planet and the Sun. The observatory will complete more than 11,000 orbits over its 25 months of planned survey operations, circling Earth about 14½ times a day. It orbits Earth from north to south, passing over the poles, and each day it takes images along one circular strip of the sky. As the days pass and the planet moves around the Sun, SPHEREx’s field of view shifts as well so that after six months, the observatory will have looked out into space in every direction.
When SPHEREx takes a picture of the sky, the light is sent to six detectors that each produces a unique image capturing different wavelengths of light. These groups of six images are called an exposure, and SPHEREx takes about 600 exposures per day. When it’s done with one exposure, the whole observatory shifts position — the mirrors and detectors don’t move as they do on some other telescopes. Rather than using thrusters, SPHEREx relies on a system of reaction wheels, which spin inside the spacecraft to control its orientation.
Hundreds of thousands of SPHEREx’s images will be digitally woven together to create four all-sky maps in two years. By mapping the entire sky, the mission will provide new insights about what happened in the first fraction of a second after the big bang. In that brief instant, an event called cosmic inflation caused the universe to expand a trillion-trillionfold.
“We’re going to study what happened on the smallest size scales in the universe’s earliest moments by looking at the modern universe on the largest scales,” said Jim Fanson, the mission’s project manager at NASA’s Jet Propulsion Laboratory in Southern California. “I think there’s a poetic arc to that.”
Cosmic inflation subtly influenced the distribution of matter in the universe, and clues about how such an event could happen are written into the positions of galaxies across the universe. When cosmic inflation began, the universe was smaller than the size of an atom, but the properties of that early universe were stretched out and influence what we see today. No other known event or process involves the amount of energy that would have been required to drive cosmic inflation, so studying it presents a unique opportunity to understand more deeply how our universe works.
“Some of us have been working toward this goal for 12 years,” said Jamie Bock, the mission’s principal investigator at Caltech and JPL. “The performance of the instrument is as good as we hoped. That means we’re going to be able to do all the amazing science we planned on and perhaps even get some unexpected discoveries.”
Color Field
The SPHEREx observatory won’t be the first to map the entire sky, but it will be the first to do so in so many colors. It observes 102 wavelengths, or colors, of infrared light, which are undetectable to the human eye. Through a technique called spectroscopy, the telescope separates the light into wavelengths — much like a prism creates a rainbow from sunlight — revealing all kinds of information about cosmic sources.
For example, spectroscopy can be harnessed to determine the distance to a faraway galaxy, information that can be used to turn a 2D map of those galaxies into a 3D one. The technique will also enable the mission to measure the collective glow from all the galaxies that ever existed and see how that glow has changed over cosmic time.
And spectroscopy can reveal the composition of objects. Using this capability, the mission is searching for water and other key ingredients for life in these systems in our galaxy. It’s thought that the water in Earth’s oceans originated as frozen water molecules attached to dust in the interstellar cloud where the Sun formed.
The SPHEREx mission will make over 9 million observations of interstellar clouds in the Milky Way, mapping these materials across the galaxy and helping scientists understand how different conditions can affect the chemistry that produced many of the compounds found on Earth today.

Skywatching Skywatching Home What’s Up What to See Tonight Meteor Showers Eclipses Moon Guide More Tips & Guides Skywatching FAQ Night Sky Network Eta Aquarids & Waiting for a Nova!
The first week of May brings the annual Eta Aquarid meteors, peaking on the 6th. And sometime in the next few months, astronomers predict a “new star” or nova explosion will become visible to the unaided eye.
Skywatching Highlights
All Month – Planet Visibility:
Venus: Appears very bright and low in the east in the hour before sunrise all month. Mars: Easy to find in the west in the first few hours of the night, all month long. Sets around midnight to 1 a.m. local time. Jupiter: Shines brightly in the west following sunset all month. Early in the month it sets about two hours after the Sun, but by late May it’s setting only an hour after sunset. Saturn: Begins the month next to Venus, low in the eastern sky before sunrise. Quickly separates from Saturn and rises higher in the sky each day before dawn. Daily Highlights
May 6 – Eta Aquarid Meteors – The peak of this annual shower is early on the morning of May 6th. The two or three nights before that are also decent opportunities to spy a few shooting stars. On the peak night this year, the Moon sets by around 3 a.m., leaving dark skies until dawn, for ideal viewing conditions. Seeing 10-20 meteors per hour is common for the Northern Hemisphere, while south of the equator, observers tend to see substantially more.
May 3 – Mars & Moon: The first quarter Moon appears right next to the Red Planet on the 3rd. Find them in the west during the first half of the night that evening.
All month – Venus & Saturn: Low in the eastern sky each morning you’ll find bright Venus paired with much fainter Saturn. They start the month close together, but Saturn pulls away and rises higher over the course of the month.
All month – Mars & Jupiter: The planets to look for on May evenings are Mars and Jupiter. They’re visible for a couple of hours after sunset in the western sky.
All month – Corona Borealis: Practice finding this constellation in the eastern part of the sky during the first half of the night, so you have a point of comparison when the T CrB nova appears there, likely in the next few months.
Transcript
What’s Up for May? Four bright planets, morning and night, a chance of meteor showers, and waiting for a nova.
May Planet Viewing
For planet watching this month, you’ll find Mars and Jupiter in the west following sunset. Mars sticks around for several hours after it gets dark out, but Jupiter is setting by 9:30 or 10 p.m., and getting lower in the sky each day. The first quarter Moon appears right next to the Red Planet on the 3rd. Find them in the west during the first half of the night that evening.

They begin the month appearing close together on the sky, and progressively pull farther apart as the month goes on. For several days in late May, early risers will enjoy a gathering of the Moon with Saturn and Venus in the eastern sky before dawn. Watch as the Moon passes the two planets while becoming an increasingly slimmer crescent. You’ll find the Moon hanging between Venus and Saturn on the 23rd.
Eta Aquarid Meteor Shower
Early May brings the annual Eta Aquarid meteor shower. These are meteors that originate from Comet Halley. Earth passes through the comet’s dust stream each May, and again in October. Eta Aquarids are fast moving, and a lot of them produce persistent dust trains that linger for seconds after the meteor’s initial streak.
This is one of the best annual showers in the Southern Hemisphere, but tends to be more subdued North of the Equator, where we typically see 10-20 meteors per hour. On the peak night this year, the Moon sets by around 3 a.m., leaving dark skies until dawn, for ideal viewing conditions. While the peak is early on the morning of May 6th, the two or three nights before that are also decent opportunities to spy a few shooting stars.
Waiting for a Nova
Sky chart showing constellation Corona Borealis with the location where nova “T CrB” is predicted to appear. The view depicts the constellation with the nova occurring, indicated by an arrow. NASA/JPL-Caltech Astronomers have been waiting expectantly for light from a distant explosion to reach us here on Earth. An event called a nova is anticipated to occur sometime in the coming months. Some 3,000 light years away is a binary star system called T Coronae Borealis, or “T CrB.” It consists of a red giant star with a smaller white dwarf star orbiting closely around it. Now the giant’s outer atmosphere is all puffed up, and the dwarf star is close enough that its gravity continually captures some of the giant’s hydrogen. About every 80 years, the white dwarf has accumulated so much of the other star’s hydrogen, that it ignites a thermonuclear explosion. And that’s the nova.
T Coronae Borealis is located in the constellation Corona Borealis, or the “Northern Crown,” and it’s normally far too faint to see with the unaided eye. But it’s predicted the nova will be as bright as the constellation’s brightest star, which is about as bright as the North Star, Polaris. You’ll find Corona Borealis right in between the two bright stars Arcturus and Vega, and you can use the Big Dipper’s handle to point you to the right part of the sky. Try having a look for it on clear, dark nights before the nova, so you’ll have a comparison when a new star suddenly becomes visible there.

NASA/JPL-Caltech Now, you may have heard about this months ago, as astronomers started keeping watch for the nova midway through 2024, but it hasn’t happened yet. Predicting exactly when novas or any sort of stellar outburst will happen is tricky, but excitement began growing when astronomers observed the star to dim suddenly, much as it did right before its previous nova in 1946. When the nova finally does occur, it won’t stay bright for long, likely flaring in peak brightness for only a few days. And since it’s not predicted again for another 80 years, you might just want to join the watch for this super rare, naked eye stellar explosion in the sky!
Here are the phases of the Moon for May.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Nemanja Jovanovic, lead instrument scientist at Caltech, presents at the Emerging Technologies for Astrophysics workshop, held at NASA’s Ames Research Center in California’s Silicon Valley. The workshop brought together experts in astrophysics to discuss how advanced technologies could impact future mission planning.NASA/Donald Richey The future of astrophysics research could unlock the secrets of the universe, and emerging technologies like artificial intelligence, quantum sensing, and advanced materials may hold the key to faster, more efficient discovery. Advancements and implementations of new technologies are imperative for observational astrophysics to achieve the next level of detection.
NASA’s Emerging Technologies for Astrophysics workshop brought together subject matter experts from industry, government, and academia to explore the state of new and disruptive technologies. The meeting was an effort to identify specific applications for astrophysics missions and better understand how their infusion into future NASA space telescopes could be accelerated.
The workshop took place at NASA’s Ames Research Center in California’s Silicon Valley,. supporting the agency’s efforts to make partnership with public and private industry and collaborative mission planning possible.
“The profound questions about the nature of our universe that astrophysics at NASA answers require giant leaps in technology,” explained Mario Perez, chief technologist for the Astrophysics Division at NASA Headquarters in Washington. “Spotting potential in early-stage tech by encouraging discussions between imaginative researchers helps expand the scope of science and lessen the time required to achieve the next generation of astrophysics missions.”
Emerging technologies like artificial intelligence can support the design and optimization of future missions, and participants focused efforts on combining technologies to push research further. “Cross-pollination” of advanced materials like composites with advanced manufacturing, metamaterials, and photonic chips could support advancement in imaging missions beyond existing mechanical stability needs.
The United Nations Educational, Scientific and Cultural Organization (UNESCO) has dubbed 2025 the “International Year of Quantum Science and Technology” in recognition of a century of quantum mechanics. Workshop participants discussed how quantum sensing could enable more precise measurements, achieve “super resolution” by filling in missing details in lower resolution images, and provide greater capabilities in forthcoming space telescopes.
“This gathering of experts was an opportunity to find ways where we can increase the capabilities of future space instrumentation and accelerate technology development for infusion into NASA astrophysics missions,” said Naseem Rangwala, astrophysics branch chief at NASA Ames. “We can speed up the process of how we develop these future projects by using the emerging technologies that are incubated right here in Silicon Valley.”
The findings from this workshop and ongoing discussions will support efforts to study and invest in technologies to advance astrophysics missions with greater speed and efficiency.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Multinational corporations are using the M2M Intelligence platform in data centers and other settings. The system offers automated, secure communications on a ground-based global 5G network. Getty Images Artificial intelligence (AI) is advancing rapidly, as intelligent software proves capable of various tasks. The technology usually requires a “human in the loop” to train it and ensure accuracy. But long before the arrival of today’s generative artificial intelligence, a different kind of AI was born with the help of NASA’s Ames Research Center in California’s Silicon Valley — one that only exists between machines, running without any human intervention.
In 2006, Geoffrey Barnard founded Machine-to-Machine Intelligence Corp. (M2Mi) at Ames’ NASA Research Park, envisioning an automated, satellite-based communication network. NASA Ames established a Space Act Agreement with the company to develop artificial intelligence that would automate communications, privacy, security, and resiliency between satellites and ground-based computers.
Central to the technology was automating a problem-solving approach known as root cause analysis, which NASA has honed over decades. This methodology seeks to identify not only the immediate cause of a problem but also all the factors that contributed to the cause. This would allow a network to identify its own issues and fix itself.
NASA Ames’ director of nanotechnology at the time wanted to develop a communications network based on small, low-powered satellites, so Ames supported M2Mi in developing the necessary technology.
Barnard, now CEO and chief technology officer of Tiburon, California-based branch of M2Mi, said NASA’s support laid the foundation for his company, which employs the same technology in a ground-based network.
The company’s M2M Intelligence software performs secure, resilient, automated communications on a system that runs across hundreds of networks, connecting thousands of devices, many of which were not built to communicate with each other. The M2Mi company worked with Vodafone of Berkshire, England, to build a worldwide network across more than 500 smaller networks in over 190 countries. The companies M2M Wireless and TriGlobal have begun using M2M Intelligence for transportation logistics.
With NASA’s help, emerging industries are getting the boost they need to rapidly develop technologies to enhance our lives.
