Quick question.  Is that hydrogen tank the STA or part of CS-1?

CS-1 flight tank. Itís being relocated to an area where additional instrumentation will be installed. After that, spray-on foam insulation will be applied in Cell N.

Cool, thank you for the update.  Looking forward to seeing it during its Green Run testing.

WHOA, SLS CS-1 Green Run testing, sound just great!  Making rain from Fire & Ice at the B-1/B-2 test stand, with 4 RS-25s thrusting at 109% AT THE SAME TIME.  I can hardly wait.

Here is a Saturn-V S1-C 1st Stage firing all five F-1 LOX/RP-1 booster engines at once, making 7.5 million pounds of thrust, in the B1/B2 test stand that is rated for 11 million pounds of thrust.
The Core Stage for SLS(SLS C/S-1) will produce about 2 million pounds of thrust from the 4 RS-25 sustainer engines.



FYI It took Boeing roughly seven to nine months to build the tanks and 14 months to complete a stage. The first stage built by Boeing was S-IC-D, a test model.

At this point in the SLS saga, I will entertain myself with something as "simple" as the upcoming RS-25 gimbal testing.

Do we have status/pictures of the CS-1 Oxygen Tank?

I donít have any pictures but I can give you a status. TPS application is complete.  Itís in Area 6 for integration of a handle full of components. After thatís done, itíll be ready for sump installation and then Forward Join stacking (Forward Skirt + LOX Tanks + Intertank).

Awesome, thank you for the update.

Preparing America for Deep Space Episode 17: Building the Future

NASA Johnson
Published on Jul 6, 2018

Important strides have been made in 2018 for NASAís Orion, Space Launch System (SLS) and Exploration Ground Systems (EGS) programs. Teams across America and in Europe are developing and building the spacecraft, rocket and infrastructure necessary to send humans to deep space destinations including the Moon and beyond. Some major milestones include: Orion Ė parachute drop testing at the Yuma Proving Ground; Exploration Mission 2 crew module cone welding; Ascent Abort-2 crew module outfitting; crew module uprighting system testing; SLS Ė intertank test article transported to NASAís Pegasus barge at Michoud Assembly Facility and arrival at Marshall Space Flight Center; core stage engine section structural tests; successful RS-25 rocket engine testing; EGS Ė Orion crew module recovery rehearsal; crew access arm install on the Mobile Launcher; Interim Cryogenic Propulsion Stage umbilical install; Firing Room 1 demonstration.

ARTICLE: Boeing finishes SLS LOX tank foam work, recovering from tube contamination issues -

by Philip Sloss.

I think that's 300 SLS articles now. And none of them are short. ;D

Reminder, this is an update only thread. No "a question" - use the discussion thread. Keeping the above as they were at least info heavy Q&A, but yeah....let's keep reading the thread titles.

From NASA's site:

Quote
Engineers installed structural test hardware for NASA's deep space rocket, the Space Launch System, into a test stand at NASA's Marshall Space Flight Center in Huntsville, Alabama where testing recently began. The test version of the SLS intertank is being pushed, pulled and bent with millions of pounds of force to ensure it can withstand the forces of launch and ascent. The test hardware is structurally identical to the flight version of the intertank that will connect the core stage's two colossal fuel tanks, serve as the upper-connection point for the two solid rocket boosters and house critical avionics and electronics. Delivered to Marshall via NASA's barge Pegasus from NASA's Michoud Assembly Facility in New Orleans this spring, the intertank is the second of four core stage structural test articles scheduled for testing at Marshall. The test facility for NASAís new exploration rocket was originally used for Saturn V rocket testing that enabled the Apollo Moon missions. The facility's special cranes and design features make it ideal for exposing large rockets and spacecraft to the extreme forces of spaceflight.

On July 24, forward skirt assembly was wrapped up with the installation of all its parts. As part of forward skirt testing, the flight computers came to life for the first time as NASA engineers tested critical avionic systems that will control the rocketís flight. The construction, assembly and avionics testing occurred at NASA's Michoud Assembly Facility in New Orleans.
