NASA to test giant supersonic Mars parachute off Hawaiian coast CBS News

The skies off the Hawaiian island of Kauai will be a stand-in for Mars as NASA prepares to launch a saucer-shaped vehicle in an experimental flight designed to land heavy loads on the red planet.
For decades, robotic landers and rovers have hitched a ride to Earth’s planetary neighbor using the same parachute design. But NASA needs a bigger and stronger parachute if it wants to send astronauts there.
Weather permitting, the space agency will conduct a test flight Tuesday high in Earth’s atmosphere that’s supposed to simulate the thin Martian air.
Cameras rigged aboard the vehicle will capture the action as it accelerates to four times the speed of sound and falls back to Earth. Viewers with an Internet connection can follow along live.
