Nasa lands saucer-shaped vehicle in test of technology for landing on Mars

A saucer-shaped Nasa vehicle launched by balloon high into Earth's atmosphere splashed down in the Pacific Ocean on Saturday, completing a successful test of technology that could be used to land on Mars.

Since the twin Viking spacecraft landed on the red planet in 1976, Nasa has relied on the same parachute design to slow landers and rovers after piercing through the thin Martian atmosphere.

The $150m experimental flight tested a novel vehicle and a giant parachute designed to deliver heavier spacecraft and eventually astronauts.

Despite small problems such as the giant parachute not deploying fully, Nasa deemed the mission a success. "What we just saw was a really good test," said Nasa engineer Dan Coatta with the Jet Propulsion Laboratory in Pasadena, California.

Viewers around the world with an internet connection followed portions of the mission in real time thanks to cameras on board the vehicle that beamed back low-resolution footage. After taking off at 11.40 am from the Pacific Missile Range Facility on the Hawaiian island of Kauai, the balloon boosted the disc-shaped vehicle over the Pacific. Its rocket motor then ignited, carrying the vehicle to 34 miles (55km) high at supersonic speeds.

Then the parachute unfurled and guided the vehicle to an ocean splashdown about three hours later. At 110 feet (33 meters) in diameter, the parachute is twice as big as the one that carried the one-tonne Curiosity rover through the Martian atmosphere in 2011.


"We want to test them here where it's cheaper before we send it to Mars to make sure that it's going to work there," project manager Mark Adler of the Nasa Jet Propulsion Laboratory said during a pre-launch news conference in Kauai in early June.


Technology development :is the surest path to Mars", Gazarik said at the briefing.
