Baku, August 30, AZERTAC
The first-ever off-Earth helicopter just hooked up with its traveling companion.
Engineers at NASA`s Jet Propulsion Laboratory (JPL) in Pasadena, California, attached the tiny Mars Helicopter to the agency`s car-size Mars 2020 rover on August 28, agency officials announced, according to space.com.
The duo will launch together in July 2020 and touch down inside the Red Planet`s Jezero Crater in February 2021. Once on Mars, the solar-powered, 4-lb. (1.8 kilograms) helicopter will detach and begin flying test sorties.
"Our job is to prove that autonomous, controlled flight can be executed in the extremely thin Martian atmosphere," Mars Helicopter project manager, of JPL, said in a statement. (Mars' air is just 1% as dense as that of Earth at sea level.)
"Since our helicopter is designed as a flight test of experimental technology, it carries no science instruments," she added. "But if we prove powered flight on Mars can work, we look forward to the day when Mars helicopters can play an important role in future explorations of the Red Planet."
For example, helicopters could serve as scouts for robots or human pioneers on Mars. Red Planet rotorcraft could also carry instruments and conduct a variety of science work of their own, NASA officials have said.
Mars 2020, which will soon get a catchier moniker via a student naming competition, will hunt for signs of long-dead Red Planet life in Jezero Crater, which hosted a river delta in the ancient past. The rover will also characterize the site's geology, collect and cache samples for future return to Earth and demonstrate gear that will generate oxygen from the carbon-dioxide-dominated Martian air, among other tasks.
NASA plans to launch another rotorcraft soon as well — Dragonfly, which will soar through the thick atmosphere of Saturn's huge moon Titan. The life-hunting Dragonfly is scheduled to lift off in 2026 and land on Titan's frigid surface in 2034.
