NASA's Orion Capsule Parachute Assembly System team loaded their capsule onto a C-17 aircraft ahead of Wednesday's test drop from 25,000 feet above.
They’re testing the complete parachute system for the Orion space craft.
It's a test to ensure the parachutes will carry the Orion capsule back to earth safely when it takes flight later this year.
Previous test determined what would happen if something goes wrong.
This time engineers are performing the test with a new piece attached to the capsule.
CPAS Liaison, Ann Bufkin says, "For the first time [we are] going to have the cover on the forward bay of the capsule, that's what they call the top part is the forward bay and that's where all the parachutes are. In order for the parachutes to start coming out when you come back from space you have to let go of that cover and it has to have a cover on it when it's in space to protect them."
The program transitioned from testing winged vehicles to capsules because they plan to go further to places like the moon, mars and asteroids.
Bufkin says, "When you go further than lower earth orbit which is like 200 mile up you're going to be coming back with a lot more intensity and speed, velocity, the velocity causes more heating on re-entry and you can't really use the winged vehicle for that."
The actual test will take place Wednesday at Yuma Proving Grounds.
