Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev exited the International Space Station at 10:18 a.m. EDT, beginning a spacewalk to remove two completed science experiments from the Poisk and Nauka modules and to install a new solar radiation-measuring device on the Zvezda service module.
Live coverage is underway as two Roscosmos cosmonauts prepare for a spacewalk outside the International Space Station. The spacewalk is scheduled to begin at approximately 10:15 a.m. EDT and last roughly five hours.
NASA’s Calibration Absolute Radiance and Refractivity Observatory Pathfinder (CLARREO Pathfinder) instrument was installed onto the International Space Station’s ExPRESS Logistics Carrier-1 platform on May 22. This mounting site on the International Space Station is a standardized external port location that provides a physical instrument interface and critical operating resources for remote science operations. The CLARREO Pathfinder […]
Robotics controllers wrapped up a weekend of swapping scientific hardware packed inside the SpaceX Dragon cargo spacecraft’s trunk for installation on the International Space Station. Meanwhile, the Expedition 74 crew is continuing its biotechnology and botany research while getting ready for a spacewalk scheduled for Wednesday, May 27.
NASA analysts and engineers have been closely tracking the agency’s sinking Neil Gehrel’s Swift Observatory as part of a fast-paced plan to raise it to a higher orbit.
After completing a series of initial test flights at high and low altitudes, NASA’s X-59 aircraft is undergoing a scheduled maintenance period inside its hangar. Teams at NASA’s Armstrong Flight Research Center in Edwards, California, have removed panels on the aircraft to take a better look inside. This allows for thorough visual inspections to confirm […]
Experiments exploring cancer treatments and cartilage repair topped the Expedition 74 crew’s research schedule on Friday. Two cosmonauts are also gearing up for a spacewalk in less than a week.
Editor’s note: This workforce note was updated on May 22, 2026, to confirm the target launch of SR-1 as targeting 2028. It has been a busy few weeks, and I wanted to provide some updates. To begin, I want to once again acknowledge the incredible contributions of the NASA workforce, along with our commercial and international […]
Four Expedition 74 astronauts had a light duty day with an array of advanced research still scheduled for Thursday. The three cosmonauts aboard the International Space Station focused on ongoing spacewalk preparations and robotics training.
The Expedition 74 crew continued exploring ways to advance cancer treatments and prevent excessive bleeding aboard the International Space Station on Wednesday. The orbital residents are also unpacking a U.S. cargo spacecraft while preparing spacesuits for an upcoming spacewalk.
