NASA completes successful test of saucer-shaped craft to be used to land on Mars
A US space agency experiment to test future Mars landing technologies proved largely successful.
A flying saucer-shaped vehicle was sent high into the atmosphere via a balloon to trial a new type of parachute and an inflatable Kevlar ring that could help slow down a spacecraft as it approaches the Red Planet's surface.
All of the equipment appeared to work apart from the parachute, which failed to deploy fully.
The experiment was sent up from Hawaii.
Nasa hopes the lessons learned will enable it put heavier payloads on Mars in the decades ahead.
