RS-25 Flight Controller Testing Continues!

This summer marked the continuation of a successful series of RS-25 engine tests at NASA's Stennis Space Center.  From NASA:

"NASA engineers closed a summer of successful hot fire testing Aug. 30 for flight controllers on RS-25 engines that will help power the new Space Launch System (SLS) rocket, being built to carry astronauts to deep-space destinations, including Mars. The space agency capped off summer testing with a 500-second hot fire of a fifth RS-25 engine flight controller unit on the A-1 Test Stand at Stennis Space Center near Bay St. Louis, Mississippi. The controller serves as the “brain” of the engine, communicating with SLS flight computers to ensure engines are performing at needed levels. The test marked another step toward the nation’s return to human deep-space exploration missions."

Powering up Orion for EM-1!

Last week, Lockheed Martin and NASA powered on the Orion spacecraft that will be launched on Exploration Mission-1.   According to NASA:

“'The initial power-on procedure verified the health and status of Orion’s core computers and power and data units and marks the beginning of critical spacecraft subsystem tests to get us ready for flight,' said Mark Kirasich, NASA Orion program manager. 'Our test team, ground support equipment and flight systems all performed remarkably well during the test. This is a major milestone for Orion and for our long range deep space exploration plans.'

"During the initial power-on tests, engineers and technicians connected the vehicle management computers to Orion’s power and data units to ensure the systems communicate precisely with one another to accurately route power and functional commands throughout the spacecraft for the duration of a deep-space exploration mission. In spaceflight, Orion will generate power through its four solar array wings which collectively hold about 15,000 solar cells that can harness enough electricity to power eight three-bedroom homes. The power and data units then distribute that power as needed throughout the spacecraft."

SLS-Orion Spin Offs

Great NASA summary of the spin-offs from the SLS and Orion programs: 

"NASA’s Orion spacecraft is designed to take astronauts farther than anyone has ever gone before: to the moon, an asteroid, and even Mars. To propel Orion into space, NASA is also developing what will be the most powerful rocket ever built, the Space Launch System (SLS). SLS and Orion will provide entirely new capabilities and will initiate the next chapter of our nation’s exploration of the solar system. All of this will be powered by cutting-edge technology that has applications not only in space but on Earth as well: advanced materials, manufacturing techniques, design software, and life support equipment are just a few of the many spinoffs that have already come from Orion and SLS—with many more sure to come."
