>NASA radio silent on contract negotiations for production of new SLS core stages & new Exploration Upper Stage liquid propellant tanks. The contract (pre-EPOC) should have been awarded by now according to NASA's schedule. According to NASA they are currently investigating cost reduction measures, and they have identified Deep Space Transport LLC (joint venture between Boeing and NG) as the sole source.
>It's notable that Boeing has adopted a policy of avoiding fixed-price contracts, which pre-EPOC and EPOC are.
>Some production of Artemis V has been authorized, but unclear how to complete it without EPOC/pre-EPOC.
>Boeing did not bid on NSSL phase 3 procurement with SLS. Boeing continues to publish study concept papers and alternative mars sample return using SLS as part of trying to find customers for SLS outside of NASA, so unclear why they did not bid.
>NASA still trying to answer the question of what Artemis III missions feasible in two years, last video discussed why Orion is unsuitable for LEO. In summary: as part of the negotiations between the Obama admin and congress after constellation was shuttered, Orion was reduced in capability to a beyond-LEO version as part of cost saving measures.
>As part of considerations for a possible modifications to enable Orion to stay in LEO for a long period, Boeing has proposed a sun-shield attached to the capsule for thermal management. Another option is modifications to the ESM.
>Axiom spacesuit design review date is under review (no, that wasn't a mistake). The design review is supposed to be completed this year, it involves a vacuum chamber test.
