NASA's Ingenuity helicopter dropped on Mars' surface ahead of flight by AFP Staff Writers Washington (AFP) April 4, 2021 NASA's Ingenuity mini-helicopter has been dropped on the surface of Mars in preparation for its first flight, the US space agency said. The ultra-light aircraft had been fixed to the belly of the Perseverance rover, which touched down on the Red Planet on February 18. "MarsHelicopter touchdown confirmed!" NASA's Jet Propulsion Laboratory tweeted Saturday. "Its 293 million mile (471 million kilometer) journey aboard @NASAPersevere ended with the final drop of 4 inches (10 centimeter) from the rover's belly to the surface of Mars today. Next milestone? Survive the night." A photograph accompanying the tweet showed Perseverance had driven clear of the helicopter and its "airfield" after dropping to the surface. Ingenuity had been feeding off the Perseverance's power system but will now have to use its own battery to run a vital heater to protect its unshielded electrical components from freezing and cracking during the bitter Martian night. "This heater keeps the interior at about 45 degrees F (7 degrees Celsius) through the bitter cold of the Martian night, where temperatures can drop to as low as -130F (-90 degrees Celsius)," Bob Balaram, Mars Helicopter Project chief engineer at the Jet Propulsion Laboratory, wrote in an update on Friday. "That comfortably protects key components such as the battery and some of the sensitive electronics from harm at very cold temperatures." Over the next couple of days, the Ingenuity team will check that the helicopter's solar panels are working properly and recharging its battery before testing its motors and sensors ahead of its first flight, Balaram said. Ingenuity is expected to make its first flight attempt no earlier than April 11, the Jet Propulsion Laboratory tweeted. Ingenuity will be attempting to fly in an atmosphere that is one percent the density of Earth's, which makes achieving lift harder -- but will be assisted by gravity that is one-third of our planet's. The first flight will involve climbing at a rate of about three feet (one meter) per second to a height of 10 feet (three meters), hovering there for 30 seconds, then descending back to the surface. Ingenuity will be taking high-resolution photography as it flies. Up to five flights of gradual difficulty are planned over the month. The four-pound (1.8-kilogram) rotorcraft cost NASA around $85 million to develop and is considered a proof of concept that could revolutionize space exploration. Future aircraft could cover ground much quicker than rovers, and explore more rugged terrain.
Rover drops off Mars Helicopter Ingenuity for first flight on Mars Pasadena CA (JPL) Apr 04, 2021 Within a few days, Ingenuity will be on the surface of Mars. Until now it has been connected to the Perseverance rover, which allowed Ingenuity to charge its battery as well as use a thermostat-controlled heater powered by the rover. 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 -130F. That comfortably protects key components such as the battery and some of the sensitive electronics from harm at very cold ... read more
