DECEMBER 12, 2022 – After its historic 25-day, 40,000-mile journey around the moon, NASA’s Orion is expected to splash land back on Earth Dec. 11.
To power its journey, Defense Logistics Agency Energy supplied the unmanned Orion capsule with 438 pounds of high purity hydrazine, 6,245 pounds of Monomethyl Hydrazine and 10,670 pounds of Nitrogen Tetroxide Mon-3 grade propellants.
The hypergolic propellants, like gasoline for a car, helps the spacecraft “drive,” change direction and slow its decent.
“The high purity hydrazine powers the 12 reaction control thrusters to control and properly orient the Orion crew module during its re-entry to Earth,” said Steve Nichols, DLA Energy Aerospace Energy Customer Operations division chief. “The other propellants are used for the Orion service module powering eight auxiliary engines and main engine.”
Orion launched on NASA’s new heavy-lift rocket, the Space Launch System, Nov. 16. It separated from the rocket after reaching space and began its journey circumnavigating the moon.
While this mission was unmanned, NASA’s Orion spacecraft is built to serve as an exploration vehicle that will carry the crew to space, provide emergency abort capability, sustain the crew during the space travel, and provide safe re-entry from deep space return velocities.
The mission, called Artemis I, is the first in a series of increasingly complex missions that will enable human exploration to the Moon and Mars.
“Aerospace Energy teams are proud to be part of this new chapter in our nation’s manned deep space missions,” Nichols said. “Perhaps DLA Energy will have a DFSP [defense fuel support point] in space one day.”
Throughout 2022, DLA Energy Aerospace Energy supported 19 Defense Department and NASA space vehicles launches with hypergolic propellants. Among these include four missions for National Reconnaissance Office, three missions for the U.S. Space Force and 11 NASA missions including the James Webb Space Telescope.
