February 10, 20215 yr Author Preparing a sample for a future mission to bring home, by 2030, is very important. If they find a biosignature it may take a sophisticated lab on Earth to come to a definitive conclusion. Unless Elon gets there first and brings it home for them. 😁 Lets hope Perseverance gets through the "7 minutes of terror" intact. The sky crane system has worked before, so hopefully all will be well. Deploys parachute at twice the speed of sound! 12,000 MPH down to 2 MPH in seven minutes. Yikes! 😬 Edited February 10, 20215 yr by martin-w

February 11, 20215 yr Hopefully, any future samples brought back from Mars will never be taken back to the surface - to be first studied on a space station in orbit - until deemed safe from any bio-hazards...

Nope, samples will be analysed on Earth, but within a secure facility. If you recall, the Apollo astronauts were confined until doctors were certain they weren't infected. Same thing.

Its going to be quite scary that "7 minutes of terror" and then of course 11 minutes or so delay until we know Perseverance is on the surface safely. Tricky place to land. Its a location that's been suggested before, for previous missions, but deemed too risky. Now it seems they have the technology to safely navigate boulders and soft Martian sand and land exactly where they intend. https://mars.nasa.gov/mars2020/ Edited February 11, 20215 yr by martin-w

Since Perseverance is still approaching aphelion (furthest distance from the Sun), it will be slowing down slightly as it makes its approach to Mars.
