Today, Boeing announced that they’ve completed the Critical Design Review (CDR) for the Exploration Upper-Stage (EUS), which is SLS’ future upgraded second-stage. Meeting this milestone allows Boeing to start construction of the EUS, which they say will be ready by 2024 for the Artemis 3 mission. The EUS has been in production hell recently, with work being halted earlier in the year in favour of building more of the inferior ICPS stages. However, after the recent SLS block buy, development has resumed. Most interestingly, we knew that during this downtime NASA had asked Boeing to upgrade the initial EUS design to send more payload to TLI; the text in this press release suggests that they’ve managed to bump it’s payload to TLI up from 37 to 45 tons. To put that in perspective, the Saturn V could send 48 tons to TLI.
