Making the voyage 1.4 million miles across the Moon and again — the farthest a spacecraft constructed for people has ever gone — the Orion spacecraft has confronted a battery of checks over time. Although Orion efficiently proved its capabilities within the harsh atmosphere of house in the course of the Artemis I mission, Orion’s analysis didn’t finish at splashdown.
The crew module, now generally known as the Orion Environmental Take a look at Article (ETA), returned to NASA’s Neil Armstrong Take a look at Facility in Sandusky, Ohio, in January 2024 and accomplished an 11-month take a look at marketing campaign vital for the security and success of Artemis II, the primary crewed mission underneath NASA’s Artemis marketing campaign.
Engineers and technicians from NASA and Lockheed Martin subjected the take a look at article to the intense circumstances Orion could expertise in a launch abort state of affairs. Within the occasion of an emergency, Orion — and astronauts inside — will jettison away from the SLS (Area Launch System) rocket for a protected touchdown within the ocean.
“This occasion could be the utmost stress and highest load that any of the techniques would see,” stated Robert Overy, Orion ETA mission supervisor, NASA’s Glenn Analysis Middle in Cleveland. “We’re taking a confirmed automobile from a profitable flight and pushing it to its limits. The protection of the astronaut crew is dependent upon this take a look at marketing campaign.”
Specialists carried out checks that simulated the noise ranges of an abort throughout launch along with the electromagnetic results of lightning strikes. The take a look at marketing campaign additionally jettisoned the take a look at article’s docking module and parachute covers, in addition to the crew module uprighting system, which consists of 5 airbags on prime of the spacecraft that inflate upon splashdown.
“It’s been a profitable take a look at marketing campaign,” Overy stated. “The info has matched the prediction fashions, and all the things operated as anticipated after being subjected to nominal and launch abort acoustic ranges. We’re nonetheless analyzing information, however the preliminary outcomes present the automobile and facility operated as desired.”
Testing Orion at such excessive acoustic ranges was a serious milestone for Artemis. The Reverberant Acoustic Take a look at Facility, the world’s strongest spacecraft acoustic take a look at chamber, was inbuilt 2011 in anticipation of this particular take a look at marketing campaign.
“These checks are completely important as a result of we’ve to finish all of those checks to say the spacecraft design is protected and we’re able to fly a crew for the primary time on Artemis II,” stated Michael See, ETA automobile supervisor, Orion Program. “That is the primary time we’ve been in a position to take a look at a spacecraft on the bottom in such an excessive abort-level acoustic atmosphere.”
A part of NASA Glenn, Armstrong Take a look at Facility is residence to the world’s largest and strongest house atmosphere simulation chambers able to testing full-sized spacecraft for all the intense circumstances of launch and spaceflight. The ability not solely homes an acoustic take a look at chamber, but additionally a thermal-vacuum chamber and spacecraft vibration system.
“The ability is exclusive as a result of there’s no different place on this planet able to testing spacecraft like this,” Overy stated. “Armstrong Take a look at Facility is a one-stop-shop for all of your testing wants to arrange your spacecraft for the extreme and difficult journey to and from house.”
Orion’s Spherical-Journey Journey to Ohio
This isn’t the primary time Orion has been contained in the partitions of the Area Environments Advanced at Armstrong Take a look at Facility. The spacecraft underwent mission-critical testing in 2019, the place it was subjected to excessive temperatures and an electromagnetic atmosphere earlier than it launched on Artemis I in 2022.
“I bear in mind when it first arrived, the gravity of its significance actually hit residence,” stated Joshua Pawlak, take a look at supervisor, NASA Glenn. “I believed to myself, on future Artemis missions, astronauts shall be inside Orion heading to the Moon, they usually’ll be relying on it for survival.”
Pawlak was a mechanical take a look at engineer when Orion made its first journey to the Sandusky facility. He participated in planning and coordinating testing of the automobile and skilled personnel. He managed the automobile from the second it arrived, by way of testing, and up till it departed for NASA’s Kennedy Area Middle in Florida.
“When it returned, I felt like I had a small half on this actually massive and thrilling factor,” Pawlak stated. “Seeing it come again blackened and scarred from the cruel atmosphere of house was unimaginable. Area will not be a pleasant house, and I felt proud realizing that if there have been astronauts on that automobile, they’d have survived.
After the Orion take a look at article departs from Glenn, it can head to Kennedy for extra testing.
“When Artemis II launches and people astronauts are sitting on board, I’ll know that I did all the things I might to make sure the automobile is prepared for them and going to carry out as anticipated,” Pawlak stated. “That’s why I do what I do.”
