Washington: NASA’s Mars Helicopter — first vehicle in history that will attempt to establish the viability of heavier-than-air vehicles flying on another planet — has successfully passed key tests, the US space agency said.

“Nobody’s built a Mars Helicopter before, so we are continuously entering new territory,” said MiMi Aung, project manager for the Mars Helicopter at NASA’s Jet Propulsion Laboratory in the US. “Our flight model — the actual vehicle that will travel to Mars — has recently passed several important tests,” said Aung. In January this year the team had operated the flight model in a simulated Martian environment.

Then the helicopter was moved to Lockheed Martin Space in Denver for compatibility testing with the Mars Helicopter Delivery System, which will hold the 1.8-kilogramme spacecraft against the belly of the Mars 2020 rover during launch and interplanetary cruise before deploying it onto the surface of Mars after landing. As a technology demonstrator, the Mars Helicopter carries no science instruments, NASA said in a statement.

Its purpose is to confirm that powered flight in the tenuous Martian atmosphere (which has one per cent the density of Earth’s) is possible and that it can be controlled from Earth over large interplanetary distances. However, the helicopter also carries a camera capable of providing high-resolution colour images to further demonstrate the vehicle’s potential for documenting the Red Planet.

The Mars Helicopter and its delivery system were checked to make sure that the electrical connections and mechanisms that linked the flight vehicle with its cradle fit snuggly. The Mars Helicopter returned to JPL on May 11 for further testing and finishing touches.
