The engine nozzle is regeneratively-cooled; the nozzle extension radiates away heat. Part of the accelerated development activity is to take another look at the overall requirements with an eye towards shortening the schedule to the first flight.

The initial Block 1 version of SLS is going through human-rating certification to be able to launch crew on Orion spacecraft beginning with the Artemis 2 launch. In the past Block 1B was planned to quickly replace Block 1 as a crew launcher for lunar missions; now SLS and Boeing are looking at whether some human-rating requirements could be deferred so that the Block 1B Cargo version could launch sooner, complementing Block 1 Crew first and replacing it later.

In contrast, on cargo vehicles the payloads attach almost directly to the rocket, have less complicated aerodynamic fairings, and no escape system requirements. Two options for early Block 1B Cargo missions would be the 8. The 8. In addition to development of the upper stage, the SLS Program would need to complete first-flight development of the payload attachment system elements.

The upgrades have key supporters in Congress, though, and appropriation bills passed there have consistently included language over the last decade mandating higher SLS performance and funding since FY specifically for EUS. Top NASA officials expressed skepticism for both possibilities during Congressional testimony in the middle of and again late in the year that EUS could be ready for a first launch in time to support the prime Artemis objective.

As noted by OMB, with the initial configuration behind schedule, still in development, and yet to fly for the first time, the only role SLS currently has in Artemis is as a crew launch vehicle. All the enabling infrastructure in the Artemis reference architecture from Gateway modules to lunar lander stages to surface logistics will be launched on commercial rockets such as the SpaceX Falcon Heavy that is flying today and others in private development that NASA does not have to directly fund.

The Block 1B Cargo variant is only being advocated outside the space agency in alternate lunar architectures. Studies such as one published by Aerojet Rocketdyne concluded that the higher predicted performance capability of SLS to the Moon would reduce the complexity of the lunar lander spacecraft and the landing mission itself, which would reduce HLS development risks to the end of goal.
