Quote...Mars 2020 Technology: Heritage and InnovationTechnologies for Entry, Descent, and LandingThe mission uses technological innovations already demonstrated successfully, especially for entry, descent, and landing (EDL). Like NASA's Curiosity rover (, the Mars 2020 spacecraft uses a guided entry, descent, and landing system. The landing system on Mars 2020 mission includes a parachute, descent vehicle, and an approach called a "skycrane maneuver" for lowering the rover on a tether to the surface during the final seconds before landing.This type of landing system provides the ability to land a very large, heavy rover on the surface of Mars in a more precise landing area than was possible before Curiosity's landing. Mars 2020 takes things one step further. It adds new entry, descent, and landing (EDL) technologies, such as Terrain-Relative Navigation (TRN). This sophisticated navigation system allows the rover to detect and avoid hazardous terrain by diverting around it during its descent through the Martian atmosphere. A microphone allows engineers to analyze entry, descent, and landing. It might also capture sounds of the rover at work, which would provide engineers with clues about the rover's health and operations, and would be a treat to hear.Technologies for Surface OperationsThe Perseverance rover design minimizes costs and risks because it is largely based on the engineering design for the previous Curiosity rover. The Perseverance long-range mobility system allows it to travel on the surface of Mars over 3 to 12 miles (5 to 20 kilometers). Improvements on Perseverance include a new, more capable wheel design. And for the first time, the rover carries a drill for coring samples from Martian rocks and soil. It gathers and stores the cores in tubes on the Martian surface, using "depot caching." Caching demonstrates a new rover capability of gathering, storing, and preserving samples. This could potentially pave the way for future missions to retrieve the samples and ferry them to Earth for intensive laboratory analysis.Perseverance tests a technology for extracting oxygen from the Martian atmosphere, which is 96% carbon dioxide. This demonstration helps mission planners test ways of using Mars' natural resources to support human explorers and improve designs for life support, transportation, and other important systems for living and working on Mars. The rover also monitors weather and dust in the Martian atmosphere. Such studies are important for understanding daily and seasonal changes on Mars, and will help future human explorers better predict Martian weather.

Quote from: Unbeliever on February 19, 2021, 01:01:24 PMI don't expect it to find any semblance of Mars life, ancient or recent. I hope to be surprised, though, because finding anything at all relating to life will teach us an enormous amount.
Quote from: Mr.Obvious on February 23, 2021, 06:28:44 PMThe fact that these things are even possible, it gives hope for mankind: speaking volumes of it's capabilities.

Imagine what could be accomplished with a more cooperative, fully-funded effort.Right now, we're doing the equivalent of exploring our room by throwing a cell phone with the camera on and downloading the camera feed on our laptop until the cell phone runs out of juice. We haven't even begun to truly explore our surroundings, but we've come a long way. A few days ago, we could barely move from one part of the bed to the other. A few days before that, we were basically blind to the outside world.If we keep this up - and it's imperative that we do - we could one day stroll around the block and finally be able to tell if anyone's out there.
