NASA has officially dated the next two Artemis missions — an orbital docking rehearsal in summer 2027 and a crewed lunar landing in 2028 — but the hardware picture is far from settled. This episode breaks down the confirmed architecture: a new extended Centaur V upper stage solving Orion's long-standing propulsion deficit, SpaceX Starship handling crewed lunar descent, and Blue Origin's redesigned Blue Moon offering a parallel path via four New Glenn launches.
The sharpest risk remains SpaceX's in-orbit propellant transfer requirement. NASA's Safety Panel estimates roughly 22 tanker launches; Elon Musk claims six to eight. That gap represents unresolved engineering — cryogenic boiloff, transfer efficiency, and demonstrated lift capacity are all still open questions. NASA is deliberately running both commercial architectures in parallel, but the 2028 timeline carries very little margin if either slips.
Beyond lunar hardware, James Webb Space Telescope delivered a striking cosmological surprise: galaxy COSMOS-74706, spectroscopically confirmed at 11.5 billion years old, is a fully formed barred spiral — a level of structural maturity current models didn't predict at just two billion years post-Big Bang. Meanwhile, ESO's Very Large Telescope announced the first plausible exosatellite candidate, a Jupiter-mass object orbiting a brown dwarf in the CD-35 2722 system, detected via radial velocity.
Rounding out the episode: the Subaru Telescope commits 100 nights to a coordinated partnership with NASA's Roman Space Telescope, targeting exoplanets, dark energy, and large-scale cosmic structure from 2027 onward.
