NASA to Test Orion Space Capsule Parachute

(Before It's News)

The NASA spacecraft that could one day help ferry humans to Mars is scheduled to undergo a parachute test tomorrow (March 8). 

The Orion spacecraft can carry humans on long trips into deep space, but once it returns to Earth, it needs a little help touching down. Like the Apollo spacecraft, Orion relies on a parachute system to lower it down through Earth’s atmosphere, and safely return astronauts to the ground.

The test is scheduled to take place at 7:30 a.m. local time (9:30 a.m. EST/1430 GMT) at the U.S. Army’s Yuma Proving Ground in Arizona. A model of Orion will be dropped from a C-17 aircraft flying at an altitude of 25,000 feet, according to a statement from the agency. NASA is currently investigating the possibility of flying two astronauts on a test flight of the Orion spacecraft as early as 2019

Tomorrow’s parachute test will simulate what would happen if an abort sequence took place during Orion’s launch. If something goes wrong with NASA’s Space Launch Systems (SLS) rocket that Orion is riding on, NASA officials may decide to abort the flight, meaning the spacecraft would be ejected from its seat atop the rocket. In such an event, the parachutes would deploy and drop the spacecraft safely back to Earth. During an abort sequence, the spacecraft will be traveling at the relatively slow speed of about 130 mph [210 km/h], rather than speeds of about 310 mph [500 km/h] during re-entry after reaching space, according to NASA. The drop will last for about four minutes total; the last one to two minutes will take place under fully deployed parachutes, according to a NASA representative.
