NASA is looking for the explorers who will help write the next chapter of human spaceflight. Applications are now open for the agency’s next class of astronauts, who will join NASA as America returns to the Moon, builds the Moon Base, and lays the groundwork for the first crewed missions to Mars. The next generation […]
NASA astronaut Anil Menon demonstrated on social media how he cast his ballot for Harris County in Texas, from space.
America’s newest aerospace expo and air show – MAX POWER – is fast approaching, and NASA has announced key events beginning Friday, Nov. 6, and running through Sunday, Nov. 8, hosted on and near the agency’s Kennedy Space Center in Florida. Through multiple park experiences at MAX POWER, NASA and a variety of external collaborators […]
Two astronauts completed a 7-hour, 11-minute spacewalk to install a new solar array on the International Space Station, bringing NASA one step closer to a major power upgrade. Once the final array is installed on November 5, the station will have up to 30% more available power, supporting critical operations and its eventual controlled deorbit.
A new study tracking 13 astronauts suggests that the human heart may be surprisingly well equipped for a journey to Mars, especially with regular exercise during spaceflight. Researchers found that astronauts' hearts adapted to months of weightlessness and handled simulated Martian gravity without major problems, offering new hope for future missions to the Red Planet.
Editor’s Note: This article was updated Thursday, Oct. 15, 2026, to reflect a change to the event start time. Students in Florida will hear from NASA astronauts Jessica Watkins and Luke Delaney as they answer prerecorded STEM questions while aboard the International Space Station. The Earth-to-space call will begin at 12:30 p.m. EDT Friday, Oct. 16, […]
NASA engineer and astronaut Christina Koch will serve as the agency’s acting deputy chief engineer beginning on Sunday, Nov. 1, following the retirement of Katherine Van Hooser, who will conclude more than 35 years of distinguished service to the agency on Wednesday, Oct. 21. In her new role, Koch will help lead NASA’s engineering community, […]
An astronaut crew that carried out an eight-month mission aboard the International Space Station splashed down as planned Thursday off the coast of California. During the mission, Sophie Adenot became the first French female astronaut to venture outside the space station for a spacewalk. In all, she undertook three spacewalks on August 18 and 25, and September 1.
NASA’s SpaceX Crew-12 astronauts have returned to Earth after 237 days in space, traveling more than 100 million miles and completing over 3,792 orbits while conducting research to prepare for future missions to the Moon and Mars. The mission also made history with record-setting spacewalk achievements and experiments that could transform medicine both in space and on Earth.
The crew completed a parachute-assisted splashdown in the Pacific Ocean off the coast of California.
As part of NASA’s ongoing Inspiration Tour, NASA astronaut Christina Koch will highlight America’s strengths in space exploration and aeronautics innovation at the Philadelphia Eagles vs. Los Angeles Rams game in Philadelphia on Sunday, Oct. 4. A self-proclaimed Philadelphia sports fan, Koch is an explorer and engineer who spent a total of 338 days in […]
Spaceflight may dramatically change the gut within weeks, causing bacteria to break down more protein as food moves more slowly through the intestines. The shift could help explain astronaut constipation and may have wider effects on health, making it an important concern for future missions to Mars.
Artemis II astronauts Victor Glover and Reid Wiseman are transitioning to emeritus status at NASA after their historic journey around the Moon earlier this year. The pair will continue advising and mentoring NASA teams as preparations accelerate for Artemis III and future lunar missions. Their experience with Orion and deep-space operations could prove especially valuable as NASA works toward returning astronauts to the lunar surface.
NASA’s Office of the Chief Health and Medical Officer formed a working group in August 2026 to review the most recent data related to extravehicular activity (EVA) prebreathe testing and decompression sickness (DCS) events, venous thromboembolism (VTE) in-flight occurrences, and patent foramen ovale (PFO) implication as they relate to NASA’s Artemis (lunar and beyond) missions. The recommendations from this working group are built upon and integrate the outcomes of previous working groups hosted by OCHMO.
