The invention relates to a vacuum experiment system applied to a manned spacecraft. The vacuum experiment system comprises a re-pressing subsystem, an experiment container subsystem, a vacuumizing subsystem and a waste gas discharging subsystem. The re-pressing subsystem comprises a re-pressing gas cylinder, a gas cylinder pressure meter, a gas cylinder manual valve, a gas cylinder disconnector, a re-pressing electric valve, a re-pressing pressure reducing valve and a re-pressing pipeline. The experiment container subsystem comprises a cavity, a cavity pressure gauge, a cavity balance valve and a cavity door. The vacuumizing subsystem comprises a vacuumizing pipeline, a vacuumizing filter and a vacuumizing electric valve. The waste gas exhaust subsystem comprises a waste gas exhaust pipeline, a waste gas exhaust filter and a waste gas exhaust electric valve. According to the invention, the problems of vacuum pumping and exhaust of the space science experiment in the sealed cabin of the manned spacecraft can be solved, the type of the space science experiment in the cabin is effectively expanded, and the in-orbit flight application value of the manned spacecraft is greatly improved.
