Nasa’s Ingenuity mini helicopter Dropped on the surface of Mars in preparation for the first flight of Marst, the US space agency said.
The ultralight aviation was fixed to the belly of the Perseverance RoverLanded on the Red Planet on February 18th. “The landing of a Mars helicopter has been confirmed!” NASA’s Jet Propulsion Laboratory tweeted over the weekend.
“The 293 million mile (471 million kilometers) journey on @NASAPersevere ended today with the final fall of 4 inches (10 centimeters) from the belly of the rover to the surface of Mars. Milestone? Survive the night. “
The photo attached to the tweet showed that patience had fallen to the surface and was then expelled from the helicopter and its “airfield.”
Ingenuity supplied Perseverance’s power system, but now it uses its own battery to run critical heaters, freezing and cracking unshielded electrical components during the fierce nights of Mars. Must be protected from.
“This heater keeps the interior at about 45 ° F (7 ° C) during the harsh cold of Martian nights. On Mars nights, temperatures can drop to -130F (-90 ° C). “” Said Bob Bararam, head of the Mars helicopter project. Jet Propulsion Laboratory engineers wrote the latest information on Friday.
“This comfortably protects key components such as batteries and some sensitive electronics from harm at very low temperatures.”
For the next few days, the Ingenuity team will verify that the helicopter’s solar panels are functioning properly, charge the battery, and then test the motors and sensors prior to the first flight, according to Baralam. ..
Ingenuity is expected to make its first flight attempt by April 11, Jet Propulsion Laboratory tweeted.
Ingenuity attempts to fly in the atmosphere, which is 1% of the Earth’s density. This makes it difficult to achieve lift, but it is supported by the gravity of one-third of the planet.
On the first flight, it climbs to a height of 10 feet (3 meters) at a speed of about 3 feet (1 meter) per second, hovering there for 30 seconds, and then returns to the surface.
With ingenuity, take high-resolution photos that fly. Up to 5 gradual difficulty flights are planned in a month.
A four-pound (1.8-kilogram) rotorcraft costs about $ 85 million to develop NASA and is considered a proof-of-concept that could revolutionize space exploration.
Future aircraft may cover the ground much faster than rover and explore steeper terrain.
