NASA’s Mars 2020 Perseverance rover will land on Mars on Feb. 18, 2021. Perseverance is the most sophisticated rover NASA has ever sent to the Red Planet, with a name that embodies NASA’s passion, and our nation’s capability, to take on and overcome challenges. It will collect carefully selected and documented rock and sediment samples for future return to Earth, search for signs of ancient microbial life, characterize the planet’s geology and climate, and pave the way for human exploration beyond the Moon.
Perseverance is also ferrying several cutting-edge technologies to the surface of Mars – including a helicopter named Ingenuity, the first aircraft to attempt powered, controlled flight on another planet.
Mars 2020 Perseverance Rover Science: Studying Mars' Habitability, Seeking Signs of Past Microbial Life, Collecting and Caching Samples, and Preparing for Future Human Missions The Perseverance rover has four science objectives that support the Mars Exploration Program's science goals: Looking for Habitability:Identify past environments capable of supporting microbial life.Seeking Biosignatures:Seek signs of possible past microbial life in those habitable environments, particularly in special rocks known to preserve signs of life over time.Caching Samples:Collect core rock and "soil" samples and store them on the Martian surface.Preparing for Humans:Test oxygen production from the Martian atmosphere.All address key astrobiology questions related to the potential of Mars as a place for life. The first three consider the possibility of past microbial life. Even if Perseverance does not discover any signs of past life, it paves the way for human life on Mars someday.
Mars 2020 Technology: Heritage and Innovation Technologies for Entry, Descent, and Landing The 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 Operations The 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.
