A method for unsealing a sealed container for extraterrestrial celestial body sample collection

Abstract

The invention discloses an unsealing method of an extraterrestrial celestial sample collection sealed container and belongs to the technical field of vacuum. The method includes the steps that gas in a transition bin, an operation bin and an unsealing bin is displaced into high-purity nitrogen; after the extraterrestrial celestial sample collection sealed container is placed in the transition bin, the transition bin is vacuumized; high-purity nitrogen in the operation bin is injected into the transition bin; the container is moved into the operation bin; the container is moved into the unsealing bin, and the container is conveyed to a set unsealing position in the unsealing bin; the unsealing bin is vacuumized, and then the container is unsealed; high-purity nitrogen in the operation bin is injected into the unsealing bin, and pressure in the operation bin and pressure in the unsealing bin are made balanced; the unsealed container is moved into the operation bin; in the operation bin, an extraterrestrial celestial sample is taken out of the unsealed container. The method solves the problems that the container cannot be easily unsealed in a high-vacuum environment and cannot be easily processed and stored in the high-purity nitrogen environment.

Description

technical field [0001] The invention belongs to the field of vacuum technology, and in particular relates to a method for unsealing a sealed container for collecting extraterrestrial celestial body samples. Background technique [0002] One of the important tasks of deep space exploration is to obtain samples of extraterrestrial celestial bodies such as soil and rocks in deep space, store them intact and bring them back to Earth for scientific research. The surface of extraterrestrial celestial bodies is generally a vacuum environment. Before the samples of extraterrestrial objects are collected, they have been preserved in the vacuum environment on the surface of extraterrestrial objects for billions of years. The research of the American Apollo program shows that extraterrestrial celestial body samples are particularly sensitive to water and oxygen in the earth's atmospheric environment. Once exposed to the earth's atmosphere, they will undergo physical or chemical reacti...
