NASA’s Mars helicopter Ingenuity touched down on the surface of the Red Planet after being dropped by its mother ship, the Perseverance rover, the space agency has announced.
Weighing in at just 4 lbs. (1.8 kilograms), Ingenuity is a tiny, solar-powered helicopter that relies on a rechargeable battery to keep its systems warm during the harsh Martian night.
Ingenuity has been attached to Perseverance’s belly, feeding off the rover’s nuclear-powered system to stay warm. Now, the helicopter is using its internal battery to power a vital heater.
NASA’s Bob Balaram, Chief Engineer for the Mars Helicopter project said: “This heater keeps the interior at about 45 degrees F through the bitter cold of the Martian night, where temperatures can drop to as low as -130 F (minus 90 degrees Celsius). That comfortably protects key components such as the battery and some of the sensitive electronics from harm at very cold temperatures.”
Ingenuity is expected to make its first flight on April 11, with the data from that test reaching Earth on April 12, NASA officials have said. The $85m drone is the first helicopter ever sent to another world and is designed to test technologies for future flying vehicles on other planets. Ingenuity carries two cameras to document its flights, which will also be observed by the Perseverance rover.
Ingenuity will perform a series of ever-longer flights over Jezero Crater (where the Perseverance rover landed on Feb. 18) over the next 31 Martian days, which are called sols. Each flight should reach no higher than 16.5 feet (5 m) and will be conducted over a 300-foot-long (90 m) flight range.
Ingenuity is just part of NASA’s ambitious Perseverance rover mission to explore an ancient delta in Mars’ Jezero Crater. The rover is expected to spend the next two years exploring the area to seek out signs of ancient life. Perseverance will also collect samples of Mars rocks to be collected and returned to Earth on a later mission.
