On September 7, 2021, NASA’s Perseverance rover completed the collection of the first sample of Martian rock. The core taken from Jezero Crater is now enclosed in an pencil-thick airtight titanium sample tube, making it available for retrieval in the future. On this occasion, we revisit a story published earlier on how NASA plans to bring back Mars samples to the Earth.
For the first 100 sols (Martian days), NASA's Perseverance rover was occupied with testing its instruments, sending to Earth pictures and sounds of Mars, performing dry runs and monitoring Ingenuity's (Mars helicopter) activities.
Now with these preliminary activities in order, Perseverance will get down to tackling its primary agenda of digging up Mars for soil samples.
Over the next two earth years, Perseverance will extensively explore the Jezero crater bed. It will collect rocks and dust samples from Mars to send back to Earth for analysis.
