Re: Scouting Mars by Helicopter

I found the answer on communications and for how long the unit might be able to last.

NASA’s little Mars helicopter has gotten a reprieve.

The rover will continue to relay data and pictures from the helicopter, but stop taking its own chopper shots. The two spacecraft must be within a half-mile (1 kilometer) of one another, for communication relay.

Designed to operate on Mars for 30 days, Ingenuity probably can survive the freezing Martian nights — and repeated flights in the extremely thin atmosphere — for at least another few months.

“We really do expect some finite life," Aung said, “and so it will be a race between how long these parts surprise us in surviving."

Mars Ingenuity helicopter given new scouting mission

The next phase extends the rotocraft's mission beyond the original month-long technology demonstration. Now, the goal is to assess how well flyers can help future exploration of Mars and other worlds.

"We're going to gather information on the operational support capability of the helicopter while Perseverance focuses on its science mission," Lori Glaze, director of NASA's Planetary Science Division, told reporters Friday.

The type of reconnaissance that Ingenuity performs could one day also prove useful to human missions, by scoping out the best paths for explorers to traverse, and reaching locations that aren't otherwise possible.

why only 30 days more has to do with design and capability.

Chief engineer Bob Balaram predicted a limiting factor will be its ability to withstand the frigid Mars nights, where temperatures plunge to -130 degrees Fahrenheit (-90 degrees Celsius).

Ingenuity keeps warm with a solar-powered heater, but it was only designed to last for a month and engineers aren't sure "how many freeze and thaw cycles (it) can go through before something breaks," he said.

wondering if the rover can place the helicopter back into the warm environment of where it was while being brought to mars....or on top of it so that it can be warmed until spring....

Re: Scouting Mars by Helicopter

Its fourth flight will be designed to show that a similar aircraft could potentially be used to map out regions of the surface and provide detailed observations over a wide area.

The “operations” phase of the demonstration will hopefully show that Ingenuity and other aircraft built using the same technology could be used to boost the speed at which new discoveries are made on Mars. The idea is to use Ingenuity in a way that future missions might use dedicated aerial science aircraft, and it’s pretty exciting stuff.


The big thing is the helicopter covers more ground faster than the rover does...but with the aid of the mapping which can be done the course for the rover to travel can be made faster....

Flight four will send the rotorcraft about 436 feet (133 meters) south to collect aerial imagery of a potential new landing zone before returning to land at Wright Brothers Field, the name for the Martian airfield on which Ingenuity’s first flight took place.

This 873-foot (266-meter) roundtrip effort would surpass the range, speed, and duration marks achieved on the third flight. Ingenuity was programmed to execute a fourth flight Friday, with a takeoff to take place at 10:46 a.m. EDT (7:46 a.m. PDT, 12:30 p.m. local Mars time) and first data to be returned at 1:39 p.m. EDT (10:39 a.m. PDT).

The fifth flight would send Ingenuity on a one-way mission, landing at the new site. If Ingenuity remains healthy after those flights, the next phase can begin.

Amazing how fast it can fly through all of that 98% carbon dioxide.
