Real world Why study samples on site?
The Apollo missions brought back about 382 kilograms of Moon rock and soil, which scientists are still studying more than 50 years later. NASA's Perseverance rover has been collecting rock samples on Mars in sealed tubes. A lab on site would let scientists choose the most interesting samples to study first.
Real world Planetary protection
If we search for life on Mars, we must make sure we do not bring Earth microbes along by accident and then "discover" them, or harm any Martian life. We also need to protect Earth from anything brought back. International planetary protection rules, overseen by COSPAR, set cleaning standards for spacecraft depending on where they go.
Possible future How the lab would work
Samples would be handled in sealed glove boxes, never exposed to the habitat air. Microscopes, chemical analysers and DNA sequencers would look for clues about the planet's history. Careful records would track every sample, and scientists on Earth could join remotely.
