Artemis III Orion Crew and Service Models Joined

Technicians joined the Orion crew and service modules together on July 30, 2026, inside the Neil Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida.

The crew module will carry and sustain NASA astronauts Randy Bresnik, Andre Douglas, and Frank Rubio, and ESA (European Space Agency) astronaut Luca Parmitano, while the service module will power and propel Orion during the mission to test rendezvous and docking capabilities with test versions, or test articles, of commercial human landing systems from Blue Origin and SpaceX.

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.

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.

Figure B includes annotations showing the local solar time on Mars during which the five individual images that captured the occultation were taken.

NASA’s Perseverance Rover Watches Earth Vanish Behind Martian Moon

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

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.
