Description

This composite of seven images from the Mastcam-Z instrument aboard NASA’s Perseverance Mars rover shows Earth, visible as a small bright dot moving from upper left to lower right, passing behind the Martian moon Phobos on July 2, 2026, 1,907th Martian day, or sol, of the mission.

The black background is the result of image processing that removed extraneous light in the background to enhance detail.

A desolate landscape with a dark horizon sits under a hazy, gray-blue sky. A large rectangular inset in the sky, connected by lines to a smaller rectangle, shows a sequence of five faint crescent shapes with a tiny bright dot moving downward.
Figure A

Figure A is an annotated composite of nine images taken by the Mastcam-Z instrument aboard Perseverance on July 2, 2026. The inset on the upper right, comprised of five images, shows Earth — the small bright dot moving from upper left to lower right — passing behind the Martian moon Phobos. 

The rectangle outlined at the left in the annotation indicates the patch of sky that was imaged several times to capture Earth passing behind Phobos. In the larger rectangular inset, the images captured from that patch of sky are displayed in time order from left to right, with Phobos moving up and Earth moving down. 

The gray of the Martian sky is the approximate true color of the twilight (about 40 minutes after sunset) on that sol. It is blue-gray lower, where it is brighter, and reddish gray above.

NASA’s Perseverance Rover Watches Earth Vanish Behind Martian Moon

Preparations for Next Moonwalk Simulations Underway (and Underwater)

Earth and the Martian moon Phobos dance together in a series of images recently acquired by NASA’s Perseverance Mars rover. Earth appears as a point of light in the Martian sky, disappearing behind the crescent of Phobos, the larger of Mars’ two moons.

This is the first time humanity has captured from the surface of another planet an observation of Earth disappearing behind an object.

The image sequence was taken by the rover’s Mastcam-Z instrument at about 7 p.m. local solar time (the Martian evening time where the rover is located) on July 2, the 1,907th Martian day, or sol, of the mission. In the composite image, Earth travels from the upper left of the frame toward the lower right while Phobos, moving from lower left to upper right, sweeps across its path. In the third frame of the sequence, the two meet, and our planet winks out behind the little moon’s shadowed edge.

“The composite image makes for a unique Earth self-portrait, taken from the surface of another planet, with a Phobos photobomb,” said Justin Maki, the Mastcam-Z deputy principal investigator and imaging scientist for Perseverance at NASA’s Jet Propulsion Laboratory in Southern California.

From where Perseverance sits on the rim of Mars’ Jezero Crater, the two objects could hardly look more different. Phobos, a lumpy, potato-shaped moon about 17 miles (27 kilometers) across at its widest, orbits so close to Mars (4,850 miles, or 7,800 kilometers, away) that when the images were taken, Phobos appears roughly one-third the width of Earth’s Moon as seen from our planet. Some 195 million miles (314 million kilometers) away at the time, Earth is reduced to a single, pixel-size dot.

“Phobos crosses the Martian sky three times a day, and Earth is visible for months at a stretch, but catching one directly behind the other takes planning and a little luck,” said Mark Lemmon, a Mastcam-Z co-investigator at the Space Science Institute in Boulder, Colorado, who planned the observation and assembled the composite.

Transits, occultations, eclipses

Astronomers call the event captured in this observation an occultation: when a larger-appearing body completely blocks the one behind it from the viewer’s standpoint. By contrast, an eclipse occurs when one object moves into the shadow of another. When the Moon passes through Earth’s shadow, it’s called a lunar eclipse; when one object that appears to be the same size as another blocks it, like when the Moon passes before the Sun, it’s known as a solar eclipse.

When the roles are reversed, with a smaller-looking object crossing the face of a larger-looking one, astronomers call that a transit. Perseverance has observed those, too: when Phobos or Deimos crosses the disk of the Sun as seen from Mars. These are sometimes described informally as “Martian solar eclipses.”

Advanced Mini-laboratories Automate Space Station Research

NASA astronaut and Expedition 71 Flight Engineer Tracy C. Dyson swaps out sample processors for the Pharmaceutical In-space Laboratory experiment that is exploring the production and manufacturing of medicines to benefit astronauts in space and humans on Earth. The processors were installed in the Advanced Space Experiment Processor, or ADSEP, that can process a variety of research samples and be delivered to the International Space Station and returned to Earth aboard the SpaceX Dragon cargo craft.

The International Space Station hosts hundreds of science experiments at a time. Some experiments can take hours to perform, and researchers need to account for astronauts’ limited time. Fully automated devices, like Redwire’s  ADvanced Space Experiment Processors (ADSEPs), have been designed to conduct more space science with less crew time.

Within each ADSEP facility there are three to four “mini-laboratories”, called cassettes, that allow multiple studies with different needs to be performed at the same time. The latest model, ADSEP-4 can accommodate four cassettes and features imagery capabilities. Since 2017, ADSEPs have conducted and supported two dozen investigations aboard space station with new ones on the horizon.

The latest ADSEP investigations are related to growing seed crystals in space, which can be used to reformulate existing drugs or develop entirely new therapeutics. Previous experiments have shown that the unique microgravity environment allows the growth of larger and higher quality crystals. With Redwire’s Pharmaceutical In-Space Laboratory (PIL-BOX), a cassette-based system that uses the ADSEP facility, researchers can grow improved, space-grown seed crystals.

Notable PIL-BOX experiments sponsored by the ISS National Laboratory have focused on cancer research. The ADSEP-PIL-10 investigation, currently being conducted in orbit in collaboration with the Aspera Biomedicines, works to crystallize cancer-blocking and cancer-promoting molecules with the goal of creating an oral cancer medication. ADSEP-PIL-15 crystalized cancer-treating medicines to help refine production, quality, and stability of these cancer drugs. A recent technology demonstration, ADSEP- ICC (Industrial Crystallization Cassette), tested a larger cassette to expand ADSEP function and scale crystallization production for commercial use.

ADSEPs are not limited to crystal growth and can also be used for culturing cells and tissues, studying organisms, and researching materials-sciences. In 2021, ADSEP-UMAMI studied how bobtail squid interacted with beneficial microbes in the space environment. This research found that symbiotic interactions with microbes can lessen a host animal’s stress responses caused by spaceflight and accelerate developmental pathways such as growing neurons and tissues. These findings give insight into the importance of symbiotic relationships in closed ecosystems like spacecraft and have implications for astronauts and their own beneficial bacteria during space missions.

The automation and versatility of ADSEPs permit a wide array of science experiments to be conducted aboard the orbiting laboratory, leading to findings that inform future space missions and are beneficial to people on Earth.

APOD: 2026 August 5 – Spokes on Saturn’s B Ring

Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

A large gaseous planet surrounded by a large ring of material (actually multiple rings). The planet and its rings are rotating. A dark shadow appears at the left side of one of the rings and disappears after a short period of time.

Spokes on Saturn’s B Ring

Explanation: Don’t get spooked by Saturn’s ghostly spokes! Today we feature a nearly two-hour timelapse of Saturn and its rings looping forwards and backwards. A day on Saturn is only 10 hours long, so two hours of observation covers quite a bit of its rotation. If you look closely, a ghoulish shadow appears and disappears as Saturn’s B ring rotates. Decades of observation with Voyager 2Cassini, and Hubble show the appearance of Saturn’s spokes varies with the planet’s seasons. Like Earth, Saturn’s spin axis is tilted compared to the plane of its orbit around the Sun. During Saturn’s equinox, the rings are less tilted away from the Sun and the planet receives more evenly distributed sunlight and solar wind. Although their origin is still uncertain, Saturn’s spokes may be shadows of and reflections off of dust and ice levitating above the rings caused by electromagnetic interactions between the solar wind and the planet’s magnetic field.

Find dark skies and look up this August to witness the Perseid meteor shower uninhibited by the Moon!
