Persevering Through the Storm
A region-wide seasonal dust storm obscures the Jezero Crater in this image from NASA’s Mars Perseverance rover, acquired using its Left Mastcam-Z camera. Mastcam-Z is a pair of cameras located high on the rover’s mast. Perseverance captured the image on Aug. 20, 2024 (Sol 1244, or Martian day 1,244 of the Mars 2020 mission) at the local mean solar time of 16:05:34. This image is part of a Mastcam-Z mosaic of the “northern fan,” a part of Jezero Crater that Perseverance never drove through, but is an area that’s thought to have been deposited in a similar way to the delta that the rover did explore. NASA/JPL-Caltech/ASU It is dust-storm season on Mars! Over the past couple of weeks, as we have been ascending the Jezero Crater rim, our science team has been monitoring rising amounts of dust in the atmosphere. This is expected: Dust activity is typically highest around this time of the Martian year (early Spring in the northern hemisphere). The increased dust has made our views back toward the crater hazier than usual, and provided our atmospheric scientists with a great opportunity to study the way that dust storms form, develop, and spread around the planet.
Perseverance has a suite of scientific instruments well-suited to study the Martian atmosphere. The Mars Environmental Dynamics Analyzer (MEDA) provides regular weather reports, the cadence of which has increased during the storm to maximize our science. We also routinely point our Mastcam-Z imager toward the sky to assess the optical density (“tau”) of the atmosphere.
There are not any signs that this regional dust storm will become planetwide — like the global dust storm in 2018 — but every day we are assessing new atmospheric data. Hopefully the skies will further clear up as we continue to climb in the coming weeks, because we are expecting stunning views of the crater floor and Jezero delta. This will offer the Perseverance team a unique chance to reflect on the tens of kilometers we have driven and years we have spent exploring Mars together.

September brings the gas giants Jupiter and Saturn back into view, along with their satellites. And while we organize celebrations to observe our own Moon this month, be sure to grab a telescope or binoculars to see other moons within our Solar System! We recommend observing these moons (and planets!) when they are at their highest in the night sky, to get the best possible unobstructed views.
The More the Merrier
As of September 2024, the ringed planet Saturn has 146 identified moons in its orbit. These celestial bodies range in size; the smallest being a few hundred feet across, to Titan, the second largest moon in our solar system.
The Saturnian system along with various moons around the planet Saturn: Iapetus, Titan, Enceladus, Rhea, Tethys, and Dione. Stellarium Web Even at nearly 900 million miles away, Titan can be easily spotted next to Saturn with a 4-inch telescope, under urban and suburban skies, due to its sheer size. With an atmosphere of mostly nitrogen with traces of hydrogen and methane, Titan was briefly explored in 2005 with the Huygens probe as part of the Cassini-Huygens mission, providing more information about the surface of Titan. NASA’s mission Dragonfly is set to explore the surface of Titan in the 2030s.
Enceladus is an icy world much like Hoth, except that it has an ocean under its frozen crust. Astronomers believe this moon of Saturn may be a good candidate for having extraterrestrial life beneath its surface. NASA/ESA/JPL-Caltech/Space Science Institute Saturn’s moon Enceladus was also explored by the Cassini mission, revealing plumes of ice that erupt from below the surface, adding to the brilliance of Saturn’s rings. Much like our own Moon, Enceladus remains tidally locked with Saturn, presenting the same side towards its host planet at all times.
The Galilean Gang
The King of the Planets might not have the most moons, but four of Jupiter’s 95 moons are definitely the easiest to see with a small pair of binoculars or a small telescope because they form a clear line. The Galilean Moons – Ganymede, Callisto, Io, and Europa – were first discovered in 1610 and they continue to amaze stargazers across the globe.
The Jovian system: Europa, Io, Ganymede, and Callisto. Stellarium Web Ganymede: largest moon in our solar system, and larger than the planet Mercury, Ganymede has its own magnetic field and a possible saltwater ocean beneath the surface. Callisto: this heavily cratered moon is the third largest in our solar system. Although Callisto is the furthest away of the Galilean moons, it only takes 17 days to complete an orbit around Jupiter. Io: the closest moon and third largest in this system, Io is an extremely active world, due to the push and pull of Jupiter’s gravity. The volcanic activity of this rocky world is so intense that it can be seen from some of the largest telescopes here on Earth. Europa: Jupiter’s smallest moon also happens to be the strongest candidate for a liquid ocean beneath the surface. NASA’s Europa Clipper is set to launch October 2024 and will determine if this moon has conditions suitable to support life. Want to learn more? Rewatch the July 2023 Night Sky Network webinar about Europa Clipper here. Be sure to celebrate International Observe the Moon Night here on Earth September 14, 2024, leading up to the super full moon on September 17th! You can learn more about supermoons in our mid-month article on the Night Sky Network page!

Time slips; a curious phenomena where individuals unexpectedly find themselves transported across time, be it minutes, days, or even years, without any intention or control over the experience. Those who experience time slips often report feeling as though they’ve been transported to a different point in time.
Imagine walking down a familiar street when suddenly everything changes. The asphalt beneath your feet transforms into cobblestone, cars vanish, replaced by horse-drawn carriages. The air fills with the scent of coal smoke and horse manure.
People in Victorian-era clothing hurry past, glancing at you suspiciously. Panic sets in as you realize you're no longer in your own time. Then, just as quickly, you're back in the present day.
You’ve just experienced a time slip, and you’re not alone.
Thousands of people worldwide have reported similar experiences, brief moments of traveling through time, witnessing scenes from the past or future, only to return to the present moment.
But what exactly are these experiences? Are they vivid hallucinations, or could time slips be real, offering us glimpses into the true nature of time and reality?
Some theories suggest that if a portal existed between our universe and a parallel one, time slips could theoretically occur. However, it’s crucial to note that there is no concrete evidence to support the idea that we live in a multiverse.
In the video below, we’ll explore a few famous time slip stories and the scientific theories that might help explain these mysterious events.

4 Min Read NASA Seeks Input for Astrobee Free-flying Space Robots
iss069e010815 (May 16, 2023) — UAE (United Arab Emirates) astronaut and Expedition 69 Flight Engineer Sultan Alneyadi observes a free-flying Astrobee robotic assistant during the testing of its operations for an upcoming student competition to control the robotic devices. Credits: NASA NASA is seeking input from American companies for the operation and use of a system of free-flying robots aboard the International Space Station as the agency continues to foster scientific, educational, and technological developments in low Earth orbit for the benefit of all.
The colorful, cube-shaped robots – named “Bumble,” “Honey,” and “Queen” – are part of the Astrobee system helping astronauts and researchers perform technology demonstrations, scientific research, and STEM (science, technology, engineering and mathematics) activities in the unique environment of space since 2018.
“Dozens of institutions collaborate with NASA to use the Astrobee system to test new hardware and software technologies,” said Jose Benavides, project manager for the Astrobee facilities at NASA’s Ames Research Center in California’s Silicon Valley, where the system was designed and built. “I’m excited to hear how respondents think Astrobee can continue to advance robotics in space.”
NASA issued a Request for Information to inform strategic planning, inviting industry to provide information to help shape the maturation of robotics in zero gravity to achieve the greatest scientific and exploration value. Responses are due Sept. 27, 2024. To learn more about the Request for Information, visit:

iss065e389375 (9/20/2021) — NASA astronaut Shane Kimbrough poses with the Astrobee robotic free-flyers in support of the Kibo Robot Programming Challenge (Robo-Pro Challenge). The Kibo-RPC, allows students to create programs to control Astrobee, a free-flying robot aboard the International Space Station (ISS). The battery-powered robots in the Astrobee system fly around the space station’s modules using electric fans for propulsion and “see” their surroundings using lights, cameras, and other sensors. They have interchangeable “arms” that provide ways for the robots to hold objects or keep steady for tasks requiring stability, and magnets to ensure they stay securely docked when recharging.
Working autonomously, or via remote control by astronauts, flight controllers, or researchers on the ground, the robots can be used to off-load time-consuming tasks. For instance, the robots can work independently or collaboratively to assist with routine chores like space station monitoring, maintenance, inventory, experiment documentation, or moving cargo throughout the station. This allows astronauts more time to tackle complex work that only humans can perform.
Astrobee’s versatile design has allowed thousands of hours of testing on hundreds of microgravity experiments. Many have involved astronauts, but the facility also is regularly used by researchers and student teams across the world competing for the opportunity to run their programs on the robots in space.
Further developing human-robotic technology will pave the way for future crewed and uncrewed spacecraft maintenance and exploration tasks done by robots both off-planet and in deep space"
Jonathan Barlow
Astrobee Project Manager
For example, NASA’s ISAAC (Integrated System for Autonomous and Adaptive Caretaking) project, used the Astrobees to study how robots could assist spacecraft, vehicle systems, and ground operators. The technology could help NASA use robot caretakers for critical spacecraft in the agency’s Moon-to-Mars plans, including the Gateway lunar space station and Mars transit habitat vehicle, especially during the months-long periods when these spacecraft will be uncrewed.
“Our ISAAC work has proved out its technology in a high-fidelity space environment because of the ready availability of the capable Astrobee robots,” said Trey Smith, project manager for ISAAC at NASA Ames.
The project demonstrated using multiple Astrobees to autonomously collect the first robot-generated survey of a spacecraft interior. Other ISAAC firsts include the first use of a robot to locate the source of a sound in space, in collaboration with the Bosch USA SoundSee payload team, and the first time robots navigated between modules of a space station. Future robots could use ISAAC technology to transfer cargo between space vehicles or respond to a time-critical fault like a leak due to a micrometeoroid impact, all without human assistance.
“With Astrobee, we’ve learned about flying multiple robots in space alongside humans,” said Jonathan Barlow, project manager for Astrobee at NASA Ames. “Further developing human-robotic technology will pave the way for future crewed and uncrewed spacecraft maintenance and exploration tasks done by robots both off-planet and in deep space.”
The Astrobee Facility, operated out of NASA’s Ames Research Center, provides a free-flying robotic system for space station research and STEM outreach. NASA’s Game Changing Development Program, part of the agency’s Space Technology Mission Directorate, funded Astrobee. NASA’s International Space Station Utilization Office provides ongoing funding.
iss071e464314 (Aug. 12, 2024) — NASA astronaut and Expedition 71 Flight Engineer Jeanette Epps monitors a pair of Astrobee robotic free-flying assistants as they demonstrate autonomous docking maneuvers inside the International Space Station’s Kibo laboratory module. The cube-shaped, toaster-sized devices were operating with a connecting interface system, called CLINGERS with an embedded navigation sensor, that may benefit construction in space.View the full article
