Commissioning of the bus, or the main structure of the satellite, has now been completed for NASA’s Arcstone lunar calibration instrument. Arcstone will now continue to go through commissioning to test its components and hardware and is expected to begin gathering science measurements approximately three weeks after launch – known as first light. As a […]
NASA’s Expedition 73 Flight Engineers Anne McClain, Nichole Ayers, and Jonny Kim called down to Earth from the International Space Station and shared an Independence Day message in this video recorded on June 16, 2025.
NASA and its partners will discuss the upcoming crew rotation to the International Space Station during a pair of news conferences on Thursday, July 10, from the agency’s Johnson Space Center in Houston. First is an overview news conference at 12 p.m. EDT with mission leadership discussing final launch and mission preparations on the agency’s YouTube channel. […]
On July 1, the NASA-funded ATLAS (Asteroid Terrestrial-impact Last Alert System) survey telescope in Rio Hurtado, Chile, first reported observations of a comet that originated from interstellar space. Arriving from the direction of the constellation Sagittarius, the interstellar comet has been officially named 3I/ATLAS. It is currently located about 420 million miles (670 million kilometers) […]
Brain research continued aboard the International Space Station on Wednesday as the Expedition 73 and Axiom Mission 4 (Ax-4) crews kept up their ongoing space biology studies. Meanwhile, a Progress cargo craft counts down to its launch to resupply the orbital residents this weekend.
Scientists with NASA’s Lucy mission continue to analyze data collected during the spacecraft’s April 20 encounter with the main-belt asteroid Donaldjohanson. The images below were taken by the spacecraft’s L’LORRI imager a few minutes before its closest approach. This successful dress rehearsal gives the team high confidence that both the spacecraft and the team are […]
The 11 crew members aboard the space station representing Expedition 73 and Axiom Mission 4 (Ax-4) returned to their space science duties on Tuesday exploring the brain circulation, observing cancer cells, and studying biotechnology, among other investigations.
The Mars 2020 Science Team gathered for a week in June to discuss recent science results, synthesize earlier mission observations, and discuss future plans for continued exploration of Jezero’s crater rim. It was also an opportunity to celebrate what makes this mission so special: one of the most capable and sophisticated science missions ever sent […]
The seven-member Expedition 73 crew wrapped up a weekend of housecleaning and relaxation then kicked off Monday with muscle and brain research aboard the International Space Station. Their Axiom Mission 4 (Ax-4) counterparts worked throughout the weekend and began the week taking a closer look at muscle cells and exploring brain computer interfaces. The public and private biology studies complement each other while the research data and hardware are supported by different organizations.
NASA has extended recovery efforts of its Lunar Trailblazer spacecraft from mid-June to early July. Updated modeling of the spacecraft’s trajectory by the mission team indicates lighting conditions will continue to be favorable and may provide enough sunlight for the spacecraft’s solar panels to recharge its batteries to an operational state and turn on its […]
