Nasa is sending a helicopter that weighs less than 2kg to Mars

The helicopter is being sent as part of the Mars 2020 mission.

THE US SPACE agency has said it plans to launch the first-ever helicopter to Mars in 2020, a miniature, unmanned drone-like chopper that could boost our understanding of the Red Planet.

Known simply as “The Mars Helicopter”, the device weighs less than 1.8 kilogrammes, and its main body section, or fuselage, is about the size of a sliotar.

It will be attached to the belly pan of the Mars 2020 rover, a wheeled robot that aims to determine the habitability of the Martian environment, search for signs of ancient life, and assess natural resources and hazards for future human explorers.

Mars 2020 is planned for launch in July 2020 with an arrival on the surface of Mars expected in February 2021.

“NASA has a proud history of firsts,” said NASA Administrator Jim Bridenstine in a statement.

The idea of a helicopter flying the skies of another planet is thrilling.

No nation has ever flown a helicopter on Mars before.

Thin atmosphere

The undertaking began in August 2013 as a technology development project at NASA’s Jet Propulsion Laboratory.

In order to fly in Mars’ thin atmosphere, the space helicopter has to be super light, yet as powerful as possible.

“The altitude record for a helicopter flying here on Earth is about 12,100 meters,” said Mimi Aung, Mars Helicopter project manager at NASA’s Jet Propulsion Laboratory.

“The atmosphere of Mars is only one percent that of Earth, so when our helicopter is on the Martian surface, it’s already at the Earth equivalent of 30,500 metres up,” she added.

Engineers built the copter’s twin, counter-rotating blades to “bite into the thin Martian atmosphere at almost 3,000 rpm – about 10 times the rate of a helicopter on Earth,” said a NASA statement.

The helicopter is equipped with “solar cells to charge its lithium-ion batteries, and a heating mechanism to keep it warm through the cold Martian nights.”

Controllers on Earth will command the Mars Helicopter, which was designed to receive and interpret commands from the ground.

Plans are being laid for a 30-day flight test, with five flights going incrementally further each time, up to a few hundred meters.

Its first flight calls for a brief vertical climb of three meters, followed by hovering for a half minute.

NASA views the copter as a “high-risk, high-reward technology demonstration,” it said.

If successful, it could be a model for scouting on future Mars missions, able to access places the human-built rovers cannot reach.

If it fails, it will not impact the Mars 2020 mission.

“The ability to see clearly what lies beyond the next hill is crucial for future explorers,” said NASA’s Thomas Zurbuchen, associate administrator for the science mission directorate.

“We already have great views of Mars from the surface as well as from orbit. With the added dimension of a bird’s-eye view from a ‘marscopter,’ we can only imagine what future missions will achieve.”

    It probably cost a trillion dollars to develop, could have bought one on amazon for $9.99 made in China

    “Human built rovers”??? As opposed to the Martian

    They’re Contra rotating blades as opposed to counter!!

    Hope everyone reading this knows what a “sliotar” is and it’s size !

    It’s hard to believe the American tax payers still buys into this NASA con artist scam and continue to allow themselves to be robbed to the tune of 31.5 million dollars per day or this unadulterated garbage.
    “Engineers built the copter’s twin, counter-rotating blades to “bite into the thin Martian atmosphere at almost 3,000 rpm – about 10 times the rate of a helicopter on Earth,” said a NASA statement”.
    Perhaps NASA “engineers” should have when to Dyson. Dyson engineers developed a DC frequency driven motor capable of speeds of 110,000 rpm! If only Dyson did Photoshop and had a film crew in Devon Canada, where the fake mars footage was shot, they could blow NASA out to space, excuse the pun!

    The singularity is here. The population of Mars is entirely made up of robots (14 of them), whilst us mere humans are unable to make the journey. All hail our robot overlords.
