The test vehicle called as the Low-Density Supersonic Decelerator (LDSD) is designed to carry scientific payload and even astronauts to Mars in future.
The spin test was to measure the spin mechanism was balanced or not, the spin test was conducted at NASA lab in La Canada, Flintridge.
The saucer spun only 30 revolutions per minute.
In june, the saucer will be transported to Hawaii.
It will be attached to a balloon that will float some 160,000 feet in the atmosphere and at this altitude, rocket will boost it further to 20,000 feet into the stratosphere, their aim here is to simulate the atmosphere on mars.
The atmosphere on mars is one percent as dense as Earth’s atmosphere.
This atmosphere is perfect for testing the test vehicle.
At present NASA is using the similar technology which they have used for the Viking probe in 1976, but they would need to test a new parachute technology because they are planning to land bigger spacecrafts and astronauts.
