With First Martian Samples Packed, NASA Perseverance Rover Initiates Ambitious Sample Return Mission
“Returning a sample from
Mars Sample Return would involve several firsts aimed at settling an open question: Has life taken root anywhere in the solar system besides Earth? “I’ve been working my whole career for the opportunity to answer this question,” said Daniel Glavin, an astrobiologist from NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Glavin is helping design systems to protect the Martian samples from contamination throughout their journey from Mars to Earth.
Collecting samples from Mars and bringing them back to Earth will be a historic undertaking that started with the launch of NASA’s Perseverance rover on July 30, 2020. Perseverance collected its first rock core samples in September 2021. Credit: NASA/ESA/
The rocket would deliver the sample capsule to Martian orbit, where an ESA orbiter would be waiting to receive it. Inside the orbiter, the capsule would be prepared for delivery to Earth by a payload being developed by a team led by NASA Goddard. This preparation would include sealing the sample capsule inside a clean container to trap any Martian material inside, sterilizing the seal, and using a robotic arm being developed at Goddard to place the sealed container into an Earth-entry capsule before the return trip to Earth.
One of the primary tasks for NASA engineers is figuring out how to seal and sterilize the sample container without obliterating important chemical signatures in the rock cores inside. Among the techniques the team is currently testing is brazing, which involves melting a metal
