In the 10 months since the rover landed, we’ve been busy! And it’s been a year of perseverance. Jessica Samuels, Perseverance Surface Operations Mission Manager: Perseverance is the first mission to collect and cache Martian rock and regolith (broken rock and dust).įor more information on the Perseverance rover, visit. The rover is characterizing the planet's geology and past climate and paving the way for human exploration of the Red Planet. Samuels also explains the next phase of Perseverance’s mission: to explore the delta that formed in Jezero billions of years ago from sediment that an ancient river carried to the shores of the lake that once existed in the crater.Ī key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. 18 flights by NASA's Ingenuity Mars Helicopter, which hitched a ride and coordinates flights with the Perseverance rover.More than 100,000 images returned, including two "selfies".Six samples and counting of Martian rock and atmosphere that could eventually be brought to Earth for further study.A new record for the longest drive in a Martian day.More than 1.8 miles (2.9 kilometers) driven.The rover team also plans to collect some images of Ingenuity.What has NASA's Perseverance rover accomplished since landing on the surface of Mars in February 2021? Surface Operations Mission Manager Jessica Samuels reflects on a year filled with groundbreaking discoveries at Jezero Crater and counts up the rover's achievements: Throughout the helicopter’s commissioning and flight test campaign, the rover will assist in communications back and forth from Earth. Once a suitable site to deploy the helicopter is found, the rover’s Mars Helicopter Delivery System will shed the landing cover, rotate the helicopter to a legs-down configuration, and gently drop Ingenuity on the surface in the first few months after landing. Only about 50% of the attempts to land on Mars, by any space agency, have been successful. To reach the Martian surface, Ingenuity rides along on Perseverance’s entry, descent, and landing system, which features a supersonic parachute, new “brains” for avoiding hazards autonomously, and components for the maneuver known as the sky crane. The power system on the Mars 2020 spacecraft periodically charges Ingenuity’s batteries on the way there. Both the rover and the helicopter are safely ensconced inside a clamshell-like entry capsule during the 293-million-mile (471-million-kilometer) journey to Mars. Ingenuity is nestled up sideways under the belly of the Perseverance rover, with a cover to protect it from the debris kicked up during landing. Ingenuity relies upon the Mars 2020 Perseverance spacecraft for safe passage to Mars and for operations on the Red Planet's surface. Its pioneering aspirations are similar to those of the Wright brothers' Flyer, which achieved the first powered, controlled flight on Earth.ģ. Ingenuity will attempt up to five test flights within a 30-Martian-day (31-Earth-day) demonstration window. That means slightly more mass can be lifted at a given spin rate. Mars does give the helicopter a little help: The gravity there is only about one-third that of Earth’s. Because the Mars atmosphere is so much less dense, Ingenuity is designed to be light, with rotor blades that are much larger and spin much faster than what would be required for a helicopter of Ingenuity’s mass on Earth. Mars has a rarefied atmosphere – just about 1% of the density of our atmosphere on Earth. One of Ingenuity’s first objectives when it gets to the Red Planet is just to survive the frigid Martian night for the first time. Tests on Earth at the predicted temperatures indicate they should work as designed, but the team is looking forward to the real test at Mars. These temperatures will push the original design limits of the off-the-shelf parts used in Ingenuity. Mars has beyond bone-chilling temperatures, with nights as cold as minus 130 degrees Fahrenheit (minus 90 degrees Celsius) at Jezero Crater. Ingenuity will attempt the first powered, controlled flight on another planet – a feat with a high degree of difficulty.
