Separated from its protective backshell, NASA’s Dragonfly rotorcraft autonomously speeds over the sand dunes of Titan. It scans the terrain below, searching for a safe place to land. When Dragonfly discovers a safe site, it turns, descends, and lands at the selected location, touching down for the first time on the surface of Saturn’s largest […]
The Expedition 75 crew worked on a 3D bioprinter and a levitation furnace at the end of the week to advance health and high-temperature physics. Two astronauts are also preparing for a spacewalk at the International Space Station as NASA announces the status of upcoming Moon missions.
Editor’s note: This story was edited on Oct. 26, 2026, to correct the number of years Mike Lippert has been flying. NASA test pilot Mike Lippert put months of simulator training and ground preparation into practice, completing his first flight in the agency’s X-59 quiet supersonic research aircraft. Lippert took off Oct. 21 from NASA’s […]
NASA’s Nancy Grace Roman Space Telescope mission has now entered the science commissioning phase, having successfully completed a comprehensive checkout and refinement of the observatory and primary instrument performance. “We’ve established that the observatory is fully functional,” said Julie McEnery, Roman’s senior project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The telescope […]
The Expedition 75 crew had a busy day on Thursday bioprinting blood vessels and trying on a spacesuit aboard the International Space Station. The orbital residents also trained to use a pair of robotic arms and set up Earth photography sessions to round out the day in low Earth orbit.
With a successful Mars gravity assist in its rearview mirror, NASA’s Psyche spacecraft has fired up its thrusters and is accelerating to the metal-rich asteroid of the same name. During the first leg of its journey, following an October 2023 launch, the mission used its electric propulsion system intermittently to maneuver to the right place […]
Spacesuit checks topped Wednesday’s task list aboard the International Space Station as two astronauts prepare for a spacewalk next week. The Expedition 75 crew members also kept up advanced microgravity research exploring space agriculture and the respiratory system midweek.
Expedition 75 spent Tuesday advancing human health on and off the Earth with 3D bioprinting, cancer research, and exercise studies. Meanwhile, spacewalk preparations continue aboard the International Space Station to augment its power generation system.
Antarctica’s Thwaites Glacier could contribute more to sea level rise by the end of the century than some previous estimates. In some model simulations, the glacier’s contribution was as much as twice current projections.
