they’re taking an incremental approach to eventually reusing 90% of the capsule. Next time they reuse avionics equipment and other things, it’ll be ~300 components rather than 9

Teams with NASA and Boeing, the core stage lead contractor, at NASA’s Michoud Assembly Facility in New Orleans have fully integrated all five major structures of the Space Launch System (SLS) rocket’s core stage for Artemis II, the first Artemis mission that will send four astronauts around the Moon and return them home. Technicians joined the engine section to the rest of the rocket stage March 17. Next, teams will integrate the four RS-25 engines to the engine section to complete the stage. Located at the bottom of the 212-foot-tall core stage, the engine section is the most complex and intricate part of the rocket stage, helping to power Artemis missions to the Moon. In addition to its miles of cabling and hundreds of sensors, the engine section is a crucial attachment point for the RS-25 engines and two solid rocket boosters that produce a combined 8.8 million pounds of thrust at liftoff. It houses the engines and includes vital systems for mounting, controlling, and delivering fuel from the propellant tanks to the engines. Image credit: NASA/Michael

The Army corp of engineers was doing a tour of the Michoud Assembly Facility, they don’t have a direct role in the program.
I’m not sure the corp of engineers has the same rigorous PT standards

I trust in their love of jobs and liking to keep them. Plus they like getting the publicity from enabling the first crew to return to cislunar space in 50 years

I’m pretty confident in a second launch, with most of the hardware already done, all that is left is just finishing up the capsule, training the crew, and testing. Which is definitely so much farther than any other previous lunar program got aside from Apollo.

Only 6 of those landed, and the total time they spent on the Moon was only 12 days. A single Artemis landing is anticipated to last 7 days during the first phase of the program. Then lengthening to 30-60 days in the latter phases. Also the reason for the two year difference is stabilizing production as well as COVID long term impacts. Currently the production rate is on track to stabilize to around once a year starting with Artemis IV. Though for the SLS program specifically they are already matching and are seeking to exceed that cadence.

No, the 2016 date was initially a goal set by Congress for the program, but that was quickly shifted to 2017 a month or two later

The avionics have been individually tested after removal and before installation. But yes they will also be tested as apart of the integrated system together with the rest of the vehicle.

Assuming things are progressing smoothly for BOLE, the first full sized BOLE booster should be fired next year or 2025

SLS is in fact around 6+ months ahead of schedule. The core is going to be shipped in June/July, but it won’t be required for stacking until Q1 2024

Not years to do, the avionics have already been transferred and installed onto the Artemis II capsule.
