Other AbstractThe spacecraft surface and internal material can adsorb molecules and particles on the ground during material processing, and will quickly release them after entering into the vacuum space.The spacecraft will be contaminated by the deposition layer on its surface due to outgassing in the space environment.This phenomenon has different levels of negative impacts on some engineer - ing systems such as solar energy system, optical remote sensing system, and passive temperature control system.Tiangong 1 target vehicle carried a QCM(Quartz Crystal Microbalance) to provide real-time contamination deposition measurements and monitor the changes of contamination deposi - tion for the first time in.It was confirmed that the deposition mass and contamination phenomenon did exist.Analysis of the monitoring data indicated that the deposition mass on the surface increased with the time, especially sharply during the period of rendezvous and docking, and the deposition rise had a negative relationship with the temperature.The effect of attitude transformation needs to be further discussed.
