NASA, Axiom Space, and SpaceX now are targeting no earlier than Sunday, June 22, for launch of the fourth private astronaut mission to the International Space Station, Axiom Mission 4.
The Sun emitted a strong flare, peaking at 5:49 p.m. ET on Tuesday, June 17, 2025. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event. Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft […]
Exercise research and spacesuit checks were the top duties aboard the International Space Station on Tuesday. The Expedition 73 crew also continued inspecting the orbital outpost’s windows and photographing Earth landmarks.
Editor’s note: This post has been updated on June 17, 2025, with more information on the target launch date. NASA’s TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) twin spacecraft have completed the final pre-shipment tests and have arrived at Vandenberg Space Force Base in California in preparations for launch later this year. The TRACERS […]
Science maintenance supporting physics research gear and window inspections kicked off the beginning of the week for the seven-member Expedition 73 crew living and working aboard the International Space Station. Meanwhile, NASA, Axiom Space, and SpaceX are reviewing launch opportunities no earlier than Thursday, June 19, for the fourth private astronaut mission to the International Space Station, Axiom Mission 4.

The Expedition 73 crew wrapped up the week with another light duty day working half a shift filled with vein scans, a pharmaceutical study, and International Space Station maintenance.
In early June, NASA’s Artemis II lunar science team ran a mission simulation for the first time in the newly completed Science Evaluation Room (SER) at the agency’s Johnson Space Center in Houston. The team of scientists used the simulation to test how they will work together to lead lunar science activities during Artemis II […]
The NISAR (NASA-ISRO Synthetic Aperture Radar) mission, an Earth-observing radar satellite jointly developed by NASA and the Indian Space Research Organisation (ISRO), moved another step closer to launch last month when it arrived safe and sound at Satish Dhawan Space Centre on India’s southeastern coast. Home to ISRO’s launch facilities, the center will host the […]
NASA and Axiom Space are postponing the launch of Axiom Mission 4 to the International Space Station. As part of an ongoing investigation, NASA is working with Roscosmos to understand a new pressure signature, after the recent post-repair effort in the aft most segment of the International Space Station’s Zvezda service module.
