In preparation for NASA’s subsequent robotic mission to Mars, the area station has carried out a profitable take a look at of a particular parachute that is designed to face up to the extreme speeds concerned throughout an atmospheric descent.
The take a look at, known as the Advanced Supersonic Parachute Inflation Research Experiment, or ASPIRE, is a prelude to the true factor the place NASA will use the supersonic parachute to land its subsequent rover on the Red Planet. The area company carried out its first take a look at of the system on October four, with the parachute deploying efficiently at a mind-numbing pace of mach 1.eight. So yeah, this is not simply any unusual parachute, as NASA’s new video makes clear.
For the take a look at, a 17.68m-tall Black Brant IX sounding rocket was launched into the higher ambiance from the NASA Goddard Space Flight Center’s Wallops Flight Facility. It carried a weighted payload in a bullet-nosed cylindrical construction, together with the parachute, the deployment system, and devices (together with a high-def digicam) to gather take a look at knowledge.
When the rocket ascended to an altitude of 32 miles (51 km), it started to fall again in direction of Earth. Some 40 seconds later, at a top of 26 miles (42 km) and at a falling pace of two,205km per hour (2,200 km/h), the system’s onboard computer systems decided that the take a look at circumstances have been met. 100 kilos of nylon and Kevlar have been shot from the rear of the automobile at almost 100 miles an hour. The parachute deployed efficiently, and with out main rips or tangles. Some 35 minutes later, the capsule splashed down within the Atlantic ocean.
“It is quite a ride,” Ian Clark, the take a look at’s technical lead from NASA’s Jet Propulsion Laboratory, stated in an announcement. “The imagery of our first parachute inflation is almost as breathtaking to behold as it is scientifically significant. 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.”
When this method is utilized in three years, the module containing the Mars 2020 rover will enter the ambiance at over 19,312km per hour (20,000 km/h). Mars has decrease gravity than Earth, plus a thinner ambiance, so the circumstances used throughout ASPIRE weren’t terribly far off from the true factor.
For this take a look at, NASA scientists used a parachute similar to the one used again in 2012 to supply the Curiosity rover to Mars. But early subsequent 12 months, the area company will take a look at a strengthened model of the parachute that could possibly be utilized in future Mars missions.[NASA Jet Propulsion Laboratory]
