NASA's first parachute test for Mars 2020 mission successful
Washington, Nov 21- NASA has successfully tested a supersonic landing parachute that will be deployed in its Mars rover mission set to launch in 2020.
The mission will rely on a special parachute to slow the spacecraft down as it enters the Martian atmosphere at over 5.4 kilometers per second.
Preparations for this mission have provided, for the first time, dramatic video of the parachute opening at supersonic speed.
The Mars 2020 mission will seek signs of ancient Martian life by investigating evidence in place and by caching drilled samples of Martian rocks for potential future return to Earth.
The mission's parachute-testing series, the Advanced Supersonic Parachute Inflation Research Experiment, or ASPIRE, began with a rocket launch and upper-atmosphere flight last month from the NASA Goddard Space Flight Center in the US.
"The imagery of our first parachute inflation is almost as breathtaking to behold as it is scientifically significant," said Ian Clark, the test's technical lead from NASA's Jet Propulsion Laboratory in the US.
"For the first time, we get to see what it would look like to be in a spacecraft hurtling towards the red planet, unfurling its parachute," Clark said.
This is the first of several tests in support of NASA’s Mars 2020 mission.
A 17.7- meter-tall sounding rocket was launched for the evaluation of the ASPIRE payload performance.
The payload is a bullet-nosed, cylindrical structure holding a supersonic parachute, the parachute's deployment mechanism, and the test's high-definition instrumentation - including cameras - to record data.
The rocket carried the payload as high as about 51 kilometres. Forty-two seconds later, at an altitude of 42 kilometres and a velocity of 1.8 times the speed of sound, the test conditions were met and the Mars parachute successfully deployed.
Thirty-five minutes after launch, ASPIRE splashed down in the Atlantic Ocean.
"We not only proved that we could get our payload to the correct altitude and velocity conditions to best mimic a parachute deployment in the Martian atmosphere, but as an added bonus, we got to see our parachute in action as well," said Clark.
The parachute tested during this first flight was almost an exact copy of the parachute used to land NASA's Mars Science Laboratory successfully on the red planet in 2012.
Future tests will evaluate the performance of a strengthened parachute that could also be used in future Mars missions. The Mars 2020 team will use data from these tests to finalise the design for its mission.
The next ASPIRE test is planned for February 2018. PTI
