The day before Artemis IV was to fly to the Moon, the last shuttle, Storm, detached from the Forward Space Station, bringing back to Earth the last seven astronauts including Li Sheng.
After the Pioneer spacecraft detached, only one shuttle was left on the Forward Space Station. To bring down all 26 astronauts, the H1 Type Firm spacecraft was used ahead of schedule, sending down 19 astronauts in two batches.
It wasn't until the early hours of February 24 that the last seven astronauts left on the shuttle after a thorough inspection, which was four days later than the planned schedule.
Through rounds of stringent checks by humans and robots alternately, the Forward Space Station had finally met the conditions for rotation.
Aside from its initial configuration, all other docked spacecraft had detached. Including the various experimental equipment and a large amount of materials it brought on later, the Forward Space Station's current mass was about 1695 tons.
