Mars rovers can only make exciting new discoveries thanks to human scientists making careful decisions about their next stop. The Mars 2020 mission is aimed at exploring the geology of Jezero Crater and seeking signs of ancient microbial life on Mars using the Perseverance rover. Scientists at NASA's Jet Propulsion Laboratory (JPL) in Southern California used novel mapping techniques to direct both the rover and the flights of the Ingenuity helicopter, which rode to Mars on Perseverance - and they did it all with open-source tools.
JPL mapping specialists Dr. Fred Calef III and Dr. Nathan Williams used geospatial analysis to help the scientific community and NASA science leadership select Jezero Crater as the landing site for Perseverance and Ingenuity. Before the vehicles arrived on Mars, they helped create maps of the terrain using data from orbiting satellites.
"Maps and images are a common language between different people - scientists, engineers, and management," Williams said. "They help make sure everyone's on the same page moving forward, in a united front to achieve the best science that we can."
