NASA Plans to Fly Helicopter on Mars

Nasa's Mars Helicopter, a small autonomous rotorcraft will travel with the Mars 2020 rover mission currently scheduled to launch in July 2020 it will demonstrate the viability of heavier-than-air vehicles on the Red Planet Tiny NASA satellite bound for Mars snaps photo of Earth from thousands of miles away

The image shows Earth as a faint blue tiny dot and a little further from it the even tinier dot that represents its natural satellite, the Moon.

The twin spacecraft have already set a distance record for CubeSats, and they were moving away from Earth at a range of 1.8 million miles (2.9 million kilometers) as of Wednesday.

NASA's Jet Propulsion Laboratory, Pasadena, California, which manages both InSight and MarCO for NASA, built the two MarCO spacecraft in JPL's CubeSat assembly clean room.

While the small CubeSats, MarCO-A and MarCO-B are not going to be the principal communications link with the InSight mission, NASA is confident that their capabilities can prove a useful array of technologies that might permit future deep space missions to conduct their individual data communications.

"CubeSats have never gone this far into space before, so it's a big milestone". "Both are CubeSats are healthy and functioning properly. We're looking forward to seeing them travel even farther", Klesh added. One of the antennas on each CubeSat, operating in X-band, is created to beam signals back to Earth from distances as far away as Mars without needing much power, an essential capability for such small spacecraft.

Now, we have another pale blue dot image, this one captured by a tiny CubeSat spacecraft, one of a pair that's shadowing NASA's InSight lander to Mars.

MarCO-A and MarCO-B also deployed a UHF radio antenna, which will receive telemetry from the InSight spacecraft as it descends through the Martian atmosphere November 26. If the mission goes as planned, they'll help send back information about InSight's descent and landing on Mars.

Nasa intends to study Mars form the sky with the help of a miniature helicopter. The US space agency intends to launch the first-ever helicopter to Mars in 2020. It is hoped that a miniature unmanned drone-like chopper could boost our understanding of

Nasa launched the Voyager 1 spacecraft on September 5 1977, and the Voyager 2 on August 20 1977. NASA pinged MarCO-B on May 9 (just a few days after launch) in order to make sure its high-gain antenna deployed correctly.

NASA sent two 30-pound (13.5-kilogram) CubeSats for redundancy in case one of the MarCO probes runs into trouble. This view of Earth and the moon was taken May 9.

But they do not carry the typical propellants used by satellites. These are considered experimental satellites, so the mission InSight won't be affected if they don't perform as intended. Eight thrusters give the team options for each correction.

Mars 2020 is slated to launch on United Launch Alliance's Atlas V rocket during that July.

MarCO's potential success could also open the door for other ways to explore our solar system according to NASA. This may only be the beginning of cubesat use in deep space missions, though.

"Exploring the Red Planet with NASA's Mars Helicopter exemplifies a successful marriage of science and technology innovation and is a unique opportunity to advance Mars exploration for the future", said Thomas Zurbuchen, Associate Administrator for NASA's Science Mission Directorate at the agency headquarters in Washington via an agency-issued release.
