plan to enter mars atmosphere 18 feb 2021

The Mars 2020 rover will still be running the GESTALT AutoNav algorithms, but when the mission launches, the new rover will be carrying an FPGA-based hardware accelerator called the Vision Compute Element (VCE) that wasn’t present on the Curiosity rover.

 Early in the landing sequence, the CVAC accelerates tasks for the Lander Vision System (LVS), which reduce the initial positioning error prior to landing from as much as 3.2 km (based on inertial measurement alone) to 40 meters. 

 

caching and depot strategy:

 

  

A. key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.

 

The rover’s initial science foray, which spans hundreds of sols (Martian days), will be complete when Perseverance returns to its landing site. At that point, Perseverance will have traveled between 1.6 and 3.1 miles (2.5 and 5 kilometers) and may have filled as many as eight of its 43 sample tubes.

After that, Perseverance will travel north, then west, toward the location of its second science campaign: Jezero Crater’s delta region. The delta is the fan-shaped remains of the spot where an ancient river met a lake within the crater. The region may be especially rich in clay minerals. On Earth, such minerals can preserve fossilized signs of ancient microscopic life and are often associated with biological processes.
