Five of the seven crew members aboard the International Space Station temporarily sheltered in the Crew Dragon spacecraft today while two cosmonauts prepared to make extensive repairs to air leaks in one portion of the Russian segment. Ultimately Roscosmos decided to postpone the repairs and use sealant as they have in the past and the crew returned to regular duties. The leaks have been a problem for several years, but recently were thought to be under control.

The repercussions of last night’s explosion of Blue Origin’s New Glenn rocket during a pre-launch test will take some time to assess. Among the key questions are not only what happened, but how badly the launch pad was damaged, which will determine how quickly launches can resume, and whether other hardware at the nearby Horizontal Integration Facility was damaged. All of the company’s customers will be impacted, but especially NASA’s Moon program.

China’s three-man Shenzhou-21 (SZ-21) crew returned to Earth today after 210 days aboard the Tiangong space station. They landed not in the SZ-21 spacecraft, however, but SZ-22. SZ-22 was launched with no one aboard because the SZ-20 spacecraft was damaged by space debris and unsafe to bring the SZ-20 crew home. They had to use SZ-21’s spacecraft.  China keeps a rocket and spacecraft ready at the launch site for emergencies like this, enabling them to quickly launch SZ-22 to serve as SZ-21’s safe haven and ride home. The SZ-23 crew is now aboard Tiangong continuing the crew handovers that began at the end of 2022.
