It's also part of the reason why COSPAR, the global Committee on Space Research, exists. It was formed in 1958 to further research, exploration and the peaceful use of outer space through international cooperation, according to the COSPAR mission statement.
In her lab, the team take samples that they collect from the spacecraft and grow them in Petri dishes to see how clean the spacecraft really is before launch. They look for evidence of spores that can attach to the spacecraft. Perseverance will collect rock, mineral and soil samples -- and those soil samples could even include microfossils from ancient organisms that may have once lived in the lake. The data it collects may be able to help scientists know if they've found a biosignature on Mars.
"Combining an understanding of the composition of the rocks, but also the very fine detail that we see in the rocks and the textures, can make a powerful case for ancient signs of life," Stack Morgan said. When Martian samples are returned to Earth and searched for evidence of life, they will be sent to biosafety level 4 laboratories, which are used to research pathogens that cause fatal diseases like coronavirus, said Jim Green, NASA's Chief Scientist.
