![]() The mission is projected to cost $2.7 billion. Additionally, science is all about being able to reproduce results getting Perseverance’s samples back to Earth means we could run the same science experiments in multiple laboratories. Despite technological advances in making small, low-power science instruments for space missions, many types of laboratory analyses still can’t be performed in space or can’t be done very precisely. ![]() Perseverance is collecting soil and rock samples as it travels, and storing them in tubes that future missions by NASA and the European Space Agency will collect. Not since 1976 has NASA directly searched for life on Mars, when the dual Viking landers performed long-shot chemistry experiments that turned up inconclusive results. It is also looking for carbon-containing molecules called organics that form the building blocks of life on Earth. There, the rover is searching for microbial fossils in rocks that formed in Mars’ warm, wet 18, 2021, it landed in Jezero crater, the site of an ancient lake and riverĭelta. Perseverance launched on Jamidst the added challenge of the global COVID-19 pandemic. Now, Perseverance will directly search for signs of past life. ![]() Building on that discovery, NASA's Curiosity rover foundĬonditions on Mars around 4 billion years ago could have supported life as we know The agency’s SpiritĪnd Opportunity rovers showed that liquid water once existed on the Program has been systematically trying to find out. Did life ever arise on Mars? For years, NASA’s Mars Exploration ![]()
