Axiom Space announced changes to their station build out plan, bringing free-flying capability forward in their timeline and switching to a berthing port at the ISS to avoid the US Deorbit Vehicle. Firefly won another CLPS task order, this time for a lander with a rover, and for quite a bit more money than the last few.
