Aerospace Bureau.
As the scheduled time for the space shuttle experiment approached, the Aerospace Bureau had been in a state of constant busyness, with all relevant departments making final preparations.
These tasks mainly involved technical calibration, equipment debugging, discussions about subsequent related work, and simulation training for the involved personnel.
The relevant personnel, including the operators of the anti-gravity propellers, were responsible for controlling the anti-gravity propellers. They would go to space with the propellers, complete their mission, and then return to Earth.
All these personnel had previous experiences in space. There had been small anti-gravity propellers before, used to launch small satellites into space, and they had participated once or many times.
If the anti-gravity propeller were considered as a space vessel, then they would be the first batch of space captains and crew. Their work sounded very grand and lofty.
