NASA and the Indian Space Research Organisation (ISRO) are targeting June 2025 for launch of the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite mission. The first mission to carry both L-band and S-band radar, NISAR will scan nearly all of Earth’s land and ice surfaces twice every 12 days. The mission will measure changes in the […]
Next NASA Balloon Flight-Ready, Awaits Launch Opportunity
The second scientific balloon in NASA’s 2025 New Zealand Super Pressure Balloon Campaign is now flight-ready and awaits a next launch opportunity from the agency’s dedicated mid-latitude launch site at Wānaka Airport, New Zealand. This will be the second and final balloon to launch for the campaign. The 18.8-million-cubic-foot (532,000-cubic-meter) helium-filled balloon will travel the […]
NASA Astronauts McClain and Ayers Reenter Station and Complete Spacewalk
NASA astronauts Anne McClain and Nichole Ayers concluded their spacewalk at 2:49 p.m. EDT. The total time was 5 hours and 44 minutes. It was the third spacewalk for McClain and the first for Ayers, and the 275th spacewalk in support of space station assembly, maintenance, and upgrades. McClain and Ayers completed their primary objectives, including […]
NASA Astronauts Begin Spacewalk to Prep Station for Future Solar Array
NASA astronauts Anne McClain and Nichole Ayers began a spacewalk at approximately 9:05 a.m. EDT to install a mounting bracket to prepare for the future installation of an additional set of International Space Station Rollout Solar Arrays. The astronauts also will relocate a space station communications antenna.
NASA Astronauts McClain and Ayers Exit Station Soon for Spacewalk
NASA’s live coverage is underway on NASA+ as two astronauts prepare to conduct a spacewalk outside the International Space Station. The spacewalk is scheduled to begin at approximately 8:15 a.m. EDT and last about six and a half hours.
Station Maneuvers to Avoid Orbital Debris
At 6:10 p.m. EDT today, the Progress 91 spacecraft thrusters fired for 3 minutes, 33 seconds to raise the orbit of the International Space Station to provide an extra distance margin from a piece of orbital debris originating from a Chinese Long March rocket body launched in 2005.
Astronauts Ready for Thursday Spacewalk as Biology, Earth Science Continues
Two NASA astronauts spent Wednesday finalizing preparations for a spacewalk to upgrade the International Space Station’s power generation capabilities and relocate a communications antenna. Expedition 73 Flight Engineers Anne McClain and Nichole Ayers began their shift staging their spacesuits and organizing their spacewalking tools inside the Quest airlock.
NASA Focuses Lunar Trailblazer Recontact Efforts Through Mid-June
As NASA continues work to reestablish command of its Lunar Trailblazer spacecraft, the mission team’s modeling indicates that the lighting conditions from May through mid-June are favorable to provide enough sunlight on the spacecraft’s solar panels to recharge the batteries to an operational level and potentially regain command of the spacecraft. Contact with the small […]
Synthetic DNA, Gravity Sensing Cells Top Research Ahead of Spacewalk
The Expedition 73 crew is learning how to manufacture nanomaterials today possibly leading to new therapeutics, vaccines, and regenerative medicine. The orbital residents also conducted vein scans and wrapped a cellular gravity sensing experiment aboard the International Space Station.
