Nasa launches helium balloon to test Mars landings

Nasa has launched a helium balloon to test possible landing systems for future flights to Mars.

The balloon took off from Hawaii carrying an experimental saucer-shaped weight.

Nasa wants to see whether this parachute can slow down the saucer when it is dropped - and whether this technology could be used for Mars landings.
