NASA is currently addressing persistent hydrogen leaks and ground equipment failures hindering the Artemis 2 moon mission's preparation. Recent "confidence tests" intended to verify repairs to the Space Launch System rocket's fueling seals were only partially successful due to a faulty filter.

Despite these technical setbacks, agency leadership remains optimistic about meeting a March launch window following an upcoming full-scale rehearsal. Administrator Jared Isaacman has indicated that while safety limits for leaks were recently relaxed based on new data, the fueling interfaces will likely require a complete redesign for future missions.

These reports highlight the ongoing financial and technical challenges of maintaining the bespoke SLS architecture as NASA transitions toward more modern, reusable flight hardware.

The deal values the combined company at roughly $1.2 trillion, stepping SpaceX up from about $800 billion and putting xAI north of $200 billion, per a source familiar with the transaction.

SpaceX is preparing to launch Starship Flight 12, the maiden flight of Block 3 vehicles. Booster 19 and Ship 39 will fly with Raptor 3 engines for the first time, generating 19 to 22 percent more thrust than Block 2. The launch window opens in late February or March 2026 from Pad 2 at Starbase. SpaceX will not attempt a booster catch on this flight. Ship 39 will attempt a controlled reentry over the Indian Ocean. The orbital refueling demonstration planned for June 2026 depends on Flight 12 succeeding, and NASA's Artemis program has no backup plan. We talk about Starship Flight 12 Technical Report, SpaceX production timeline and testing milestones, FCC communications window filing and NASA Artemis program dependencies.The Starship system is a fully reusable, two‑stage‑to‑orbit super heavy‑lift launch vehicle under development by SpaceX. The system is composed of a booster stage named Super Heavy and a second stage, also called "Starship" and is being built at Starbase, Texas.
