'Marscopter' to offer NASA birds-eye view of the Red Planet

The rotor craft weighs in at only 1.8 kilograms, and it will fly to Mars attached to the underbelly of the rover. The official announcement came forwards from the NASA's desk on May 11, 2018. Those commands will take several minutes to reach the helicopter from Earth, so it will need some autonomous capabilities to make sure it can fly on its own, without anyone controlling it in real time.

"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", Thomas Zurbuchen, Associate Administrator for NASA's Science Mission Directorate, says in a statement.

He added, though, that Mars 2020 has worked to accommodate the helicopter, and was not concerned about any technical risk to the mission from it. At a meeting of the National Academies' Space Studies Board May 3, Ken Farley, project scientist for Mars 2020, said he and others on the mission had concerns about flying that technology demonstration.

The helicopter looks like "a medium-size cubic tissue box,"according to NASA's Jet Propulsion Lab (JPL) in Pasadena, California, which designed it". It has a body that resembles a softball. The Mar's helicopter is accompanied with solar cells. The vehicle will then land and recharge its batteries for about one Martian day (two Earth days), Farley said. "This is a process that has taken place at NASA Headquarters to decide whether the helicopter should be flown". It's also limited to the open expanses of the planet.

Due to the much thinner Martian atmosphere, the blades of the aircraft need to spin about 10-times faster than those of a normal helicopter to generate lift. The rate of blade whirling is three thousand rpm.

NASA will send a tiny helicopter to Mars along with its next rover in July 2020. The rocket, which will accomplish the mission, is named as United Launch Alliance's Atlas V rocket. It's expected to reach the planet on February 2021.

The Rover will perform geological tests, search for signs of ancient Martian life, and assess resources and hazards for future human explorers.

The Mars Helicopter is considered a high-risk, high-reward project, according to NASA: If the helicopter fails, it won't affect the rest of the Mars 2020 rover's mission, but if it succeeds, the agency will have a powerful new tool to survey the planet and access now unreachable locations. One of the rover's key tasks will be to collect samples of Martian rock and soil that could be returned to Earth during a follow-up mission.
