NASA plans to hedge its Commercial Crew Program by adding missions to SpaceX as Boeing spacecraft certification remains uncertai NASA intends to add missions to SpaceX’s Commercial Crew contract, explicitly protecting the program against a scenario in which Boeing’s spacecraft is never certified. The move underscores NASA’s need for schedule assurance as certification outcomes drive downstream crew-transport planning.

Hubble-era reanalysis casts doubt on Europa’s water-vapor “geysers”, weakening a key indicator of current activity A new assessment of 14 years of Hubble Space Telescope observations finds that Europa’s supposed water-vapor eruptions may not be real. The study reopens the question of what drives Europa’s near-surface volatiles and how strongly current plume activity should factor into observational and mission targeting.

NASA ranks lunar technology pain points and maps FY26 space-tech funding to civil shortfalls and Ignition NASA gathered stakeholder input to identify the technical challenges causing the biggest “headaches” for space technology—and then translated that feedback into 40 space-technology focus areas for FY26. The roadmap is shaped by civil space capability shortfalls and NASA’s new Ignition initiative to prioritize near-term investment bets.
