The engine controller unit on the RS-25 — formerly known as the space shuttle main engine — helped propel all of the space shuttle missions to space. It allows communication between the vehicle and the engine, relaying commands to the engine and transmitting data back to the vehicle. The controller also provides closed-loop management of the engine by regulating the thrust and fuel mixture ratio while monitoring the engine’s health and status. Just like the ever-evolving computer, the engine controller unit needed a “refresh” to provide the capability necessary for four RS-25 engines to power the core stage of NASA’s new rocket, the Space Launch System (SLS), to deep space missions.
United Launch Alliance Successfully Launches NASA’s Orion Spacecraft on Critical Flight Test for Lockheed MartinDecember 5th, 2014
Cape Canaveral Air Force Station, Fla., (Dec. 5, 2014) – A United Launch Alliance (ULA) Delta IV Heavy rocket carrying NASA’s Orion spacecraft for Lockheed Martin successfully launched from Space Launch Complex-37 at 7:05 a.m. EST today. This uncrewed flight test called Exploration Flight Test-1 tested Orion’s systems critical to crew safety. “We are truly […]
Orbiting above Earth attached to the Delta IV second stage, Orion’s telemetry shows all systems working well on NASA’s newest spacecraft designed for astronauts. The next major stages in the flight test will begin with the re-ignition of the second stage engine. That 4 1/2-minute burn will send Orion out of low Earth orbit and […]
Humanity’s first effort to send humans into deep space and to other planets in our solar system begins in just two weeks. The launch window for NASA’s newest spacecraft, Orion, opens Dec. 4. While the world has been fixed on the Mars Rover and, more recently, a successful effort to land a robot on a […]
The barrel for the engine section of NASA’s new rocket, the Space Launch System, is taken off the Vertical Weld Center at NASA’s Michoud Assembly Facility in New Orleans. The barrel is flight hardware to be used on the first uncrewed test flight of the 70-metric-ton configuration of the rocket. The engine section, made up […]
The Orion spacecraft moved from the Launch Abort Servicing Facility at NASA’s Kennedy Space Center on Nov. 11 to Space Launch Complex 37 at Cape Canaveral Air Force Station. After arriving at the pad Nov. 12, Orion was lifted for stacking on the United Launch Alliance Delta IV Heavy rocket in preparation for its flight […]
By Linda Herridge NASA’s John F. Kennedy Space Center NASA’s Orion spacecraft moved Nov. 11 from the Launch Abort System Facility (LASF) at NASA’s Kennedy Space Center in Florida, and arrived at Space Launch Complex 37 at Cape Canaveral Air Force Station (CCAFS) on Nov. 12 in preparation for its upcoming flight test. The assembled Orion […]
The first flight version of NASA’s Orion space vehicle is fully assembled and will be moved to its launch pad in Florida in coming weeks for an unmanned test launch Dec. 4.
NASA’s Orion spacecraft is well on its way to making this sort of space exploration beyond the Moon a reality. It is NASA’s first spacecraft designed to carry humans on missions of long duration in deep space exploration.
The stars are aligning for the December 4 debut mission of NASA’s Orion spacecraft, following the completion of the Flight Readiness Review (FRR) – albeit with three “actions” to satisfy ahead of flight. The vehicle also completed all assembly tasks and is almost ready to meet up with her Delta IV Heavy launch vehicle for the key test flight of NASA’s deep space exploration crew transport.
