SLS Test Hardware Taken to Redstone Arsenal Airfield for Guppy Loading

Published on Jul 14, 2017


A structural test article of the Orion Stage Adapter for NASA’s Space Launch System, built at NASA's Marshall Space Flight Center, is transported and prepared to be loaded onto NASA's Super Guppy aircraft. With integrated structural testing complete at Marshall, the stage adapter will soon be transported to Lockheed Martin in Denver for further testing with NASA's Orion spacecraft. The Guppy -- a plane large enough to carry cargo weighing more than 26 tons -- arrived at the U.S. Army's Redstone Arsenal Airfield July 10 to transport the stage adapter. On SLS's first integrated flight with Orion, the OSA will connect Orion to the Interim Cryogenic Propulsion Stage.

ULA's ICPS for SLS EM-1 is on a road trip this morning! Cape, via LC-39 complex and KSC’s Industrial Area, to the SSPF. The first integrated piece of SLS hardware to arrive at KSC.

Service Platforms Arrive for Space Launch System Booster Engines
Posted on August 4, 2017 at 11:05 am by Linda Herridge.

New service platforms for NASA’s Space Launch System (SLS) booster engines arrived at the agency’s Kennedy Space Center in Florida. The platforms were transported on two flatbed trucks from fabricator Met-Con Inc. in Cocoa, Florida. They were offloaded and stored inside the Vehicle Assembly Building (VAB).

The platforms will be used for processing and checkout of the engines for the SLS’ twin five-segment solid rocket boosters for Exploration Mission-1 (EM-1). The boosters, in combination with the rocket’s four RS-25 engines, will produce more than 8 million pounds of thrust at liftoff.

The first SLS mission, EM-1, will launch an uncrewed Orion spacecraft to a stable orbit beyond the Moon and bring it back to Earth for a splashdown in the Pacific Ocean. The mission will demonstrate the integrated system performance of the rocket, Orion spacecraft and ground support teams prior to a crewed flight.

Tanks for the lift

NASA’s powerful Space Launch System rocket is a few steps closer to launching the Orion spacecraft now that its liquid propellant tanks are ready for testing.

Assembled by the world’s largest robotic rocket welder at NASA’s Michoud facility in New Orleans, USA, the liquid oxygen tank seen here is ready for qualification, while the remaining three tanks are being processed.

The tanks must prove they can do exactly what they were designed to do as well as pass structural testing. At NASA’s Marshall Space Flight Center in Huntsville, Alabama, they will be strapped to the engines and fired to check their performance under launch conditions.

The liquid oxygen and hydrogen tanks hold over 2.6 million litres of propellant to power the rocket’s core stage that is comprised of four RS-25 engines and two solid rocket boosters.

Every bit of that thrust will be needed to propel the Orion spacecraft beyond low orbit to the Moon and beyond, for which ESA is contributing the European Service Module (ESM).

Once in orbit, the ESM will provide the spacecraft with electricity, water, oxygen and nitrogen as well as temperature control. A propulsion qualification module is being tested at the White Sands Test Facility in the US.

NASA’s uncrewed Exploration Mission-1 will be launched from the historic pad 39B at the Kennedy Space Center in Cape Canaveral, sending Orion some 70 000 km beyond the Moon before it returns to Earth.

Media tour and briefing of the Launch Equipment Test Facility (LETF) and the SLS EM-1 Interim Cryogenic Propulsion Stage (ICPS).  If you've got questions you'd like me to ask tomorrow, PM me before 9am EDT Friday.

Update on the "dropped LOX dome"-incident via het most recent publically available ASAP minutes:

Quote from: ASAP
NASA also reported on a mishap with the LOX dome. The qualification dome was dropped and its sides were “dimpled” by its holding fixture. At first, this was thought to be a catastrophic failure, but when the team pulled the dome out of the fixture, the dimples popped out. After considerable analysis by NASA and the prime contractor, the LOX dome was deemed suitable for qualification testing. It will be attached to the qualification tank and that assembly will go to Stennis Space Center for structural testing.

Update on SLS-related critical path items, via the most recent publically available ASAP minutes:

Quote from: ASAP
The overall launch schedule for EM-1 has slipped—it is moving out and a new date will be established in the near future. There are a number of schedule threats within the three program-critical paths. The principal one migrates through the core stage (the rocket). A number of actions must come together: the fabrication and test of qualification and flight test hardware, fabrication and testing of structural test articles, and the integration of sensors and avionics. There are schedule threats of several months in terms of delivery of hardware to testing. This remains a difficult task to traverse without delay.

NASA's Marshall Center
Published on Aug 29, 2017


Animation depicting NASA’s Space Launch System, the world's most powerful rocket for a new era of human exploration in deep space. Black-and-white checkerboard targets on the exterior of the SLS heavy-lift rocket will enable photogrammetrists to measure critical distances during spaceflight, including booster separation from the core stage. With its unprecedented capabilities, SLS will launch astronauts in the agency’s Orion spacecraft on missions to explore multiple, deep-space destinations, including Mars.

That Dynetics simulated SLS would look great as a museum piece for KSC to add.  A life size SLS replica right outside the Atlantis building. Not only is it new, but this also shows hardware heritage adapted from shuttle into the new rocket. People will also get a sense of how large it is standing next to it while comparing it to the shuttle ET/SRB stack next to it. :)

Great article, but lacking proper metric units. Don't want to alienate the rest of the world!

Isn't SLS being built using Imperial units?  If so, the most precise numbers will be in those units.

US Imperial Units is primary measurement and Metric is listed as secondary per Space Launch System (SLS) Mission Planner's Guide - ESD 30000 Baseline. PSM most charts are hybrid.
