SLS and Orion: June 2013 Archives

Nelson warns of partisan "chaos" regarding NASA authorization, Space Politics

"Immediately after the House Science Committee's space subcommittee wrapped up its hearing on a draft NASA authorization bill Wednesday morning, Sen. Bill Nelson (D-FL) offered his views on the subject at a Space Transportation Association luncheon on the other side of Capitol Hill. Nelson, chairman of the space subcommittee of the Senate Commerce Committee, said his committee was working on its own version of a NASA authorization bill that would be ready by mid-July or perhaps sooner, in order to support appropriators."

What we're going to try to mark up is a balanced program," he said, citing progress in both commercial crew development and the Space Launch System and Orion programs, as well as science programs, including the James Webb Space Telescope."

Hot-Fire Tests Steering the Future of NASA'S Space Launch System Engines, NASA

"Engineers developing NASA's next-generation rocket closed one chapter of testing with the completion of a J-2X engine test series on the A-2 test stand at the agency's Stennis Space Center in Mississippi and will begin a new chapter of full motion testing on test stand A-1.

... The March 7 test, which set the short-lived duration record, was remarkable for another reason in that it marked the first time a 3-D printed part was hot-fire tested on a NASA engine system.

The prime contractor for the liquid engine, Pratt & Whitney Rocketdyne of Canoga Park, Calif., built a maintenance port cover for the 10002 engine using an advanced manufacturing process called Selective Laser Melting. This construction method uses lasers to fuse metal dust into a specific pattern to build the needed part."

NASA's Space Launch System Program Kicks Off Preliminary Design Review, NASA

"NASA is beginning a preliminary design review for its Space Launch System (SLS). This major program assessment will allow development of the agency's new heavy-lift rocket to move from concept to initial design.

The preliminary design review process includes meticulous, detailed analyses of the entire launch vehicle. Representatives from NASA, its contractor partners and experts from across the aerospace industry validate elements of the rocket to ensure they can be safely and successfully integrated.

... We are on track and meeting all the milestones necessary to fly in 2017."

J-2X Update

LEO Progress: J-2X to Test Stand A1, NASA Blog (Liquid Rocket Engines)

"Recently, J-2X development engine 10002 was on the road. If you remember, E10002 went through a six-test series on test stand A2 that began in February and finished up in April. The next planned phase of E10002 testing is on test stand A1. In between these series, the engine was back in the assembly area of NASA Stennis Space Center Building 9101.

This respite between test series allowed for a complete series of inspections of the engine hardware. This is vital piece of the learning process for engine development. The basic truth is that a rocket engine is just darn tough on itself when it fires. The reason that we test and test and test is to make sure that our design can stand up to the recurring brutal conditions. The chance to look for the effects of that testing through detailed inspections away from the test stand is an opportunity to collect a great deal of useful information. "

NASA Invites Media to View Space Launch System Progress, NASA

"NASA Associate Administrator for Human Exploration and Operations William Gerstenmaier and other agency officials will debut a new machine for manufacturing NASA's Space Launch System (SLS) and check on development progress with the heavy-lift rocket at the agency's Michoud Assembly Facility in New Orleans Friday, June 21.

NASA is inviting media representatives to attend a 9:15 a.m. CDT ribbon-cutting ceremony for the vertical weld center, where friction-stir weld tooling will be used to assemble the SLS core stage, then join officials on a tour of the SLS assembly area and work in support of NASA's Orion spacecraft."

NASA's Orion Program First Fairing Separation Test Provides Data To Validate Design, NASA

"NASA is carrying out a series of tests to ensure the agency's Orion spacecraft can successfully jettison its protective fairings, or covers, during its ride to space. During the first of these tests, two of the three fairing panels separated as planned, but a third didn't."

NASA, Partner Collaborate on Key Piece of Orion Hardware, OnOrbit

"Technicians from Janicki Industries in Hamilton, Wash., work in collaboration with NASA's Langley Research Center in Hampton, Va., and NASA's Marshall Space Flight Center in Huntsville, Ala., to build part of the Space Launch System, NASA's next-generation launch vehicle."

"They are specifically working on a diaphragm for the Multipurpose Crew Vehicle Stage Adapter (MSA). Joint efforts between NASA and Janicki Industries enable engineers to verify proper functioning of this part of the SLS vehicle with the Orion spacecraft during its first mission -- Exploration Flight Test -1 (EFT-1) -- scheduled to launch in 2014."

Production of Key Equipment Paves Way for NASA SLS RS-25 Testing, NASA Marshall

"NASA plans to begin testing RS-25 engines for its new Space Launch System (SLS) in the fall of 2014, and the agency's Stennis Space Center in Mississippi has a very big -- literally -- item to complete on the preparation checklist.

Fabrication recently began at Stennis on a new 7,755-pound thrust frame adapter for the A-1 Test Stand to enable testing of the engines that will provide core-stage power for NASA's SLS. The stand component is scheduled to be completed and installed by November 2013."
