Super Heavy has splashed down in The Gulf of Mexico

Launch & test outcomes

• Super Heavy booster performed a controlled descent from ~90 km, executed a landing burn, and achieved a soft splashdown in the Gulf of Mexico (no recovery planned).
• Starship upper stage reached space, survived atmospheric reentry, flipped to vertical and executed a landing burn for a soft splashdown in the Indian Ocean.
• Several engines failed on ascent and on booster landing burn, but redundancy allowed mission goals to be met.
• Many commenters frame this as a major milestone toward full reuse and NASA’s Artemis lunar lander commitments.

Reentry, heat shield, and the “hero flap”

• Live video showed spectacular plasma effects and progressive damage to a forward flap: tiles lost, structure glowing, metal apparently melting and depositing on the camera cover.
• Despite heavy visible damage, the flap and actuators still worked well enough to maintain control and complete the flip and landing burn.
• People infer: core tanks and main structure remained intact; flap‑hinge thermal protection and local tile design likely need redesign.
• Some suggest the test intentionally included weakened/modified tiles to gather data on failure modes.

Starlink comms, telemetry & cameras

• Continuous high‑bandwidth telemetry and multi‑camera HD video were streamed through Starlink during ascent and deep into reentry.
• Discussants note this is unusual compared to historic “blackout” periods and see it as a strong demo of Starlink and Starship’s size creating a “plasma hole”.
• Some disappointment that camera covers cracked or were obscured by debris near the end, but most prioritize data over visuals.

Engineering approach & reuse strategy

• Many praise SpaceX’s rapid, test‑heavy iteration and willingness to show failures publicly.
• Debate over when to attempt catching the booster with launch‑tower “chopsticks”; several expect more ocean splashdowns first due to remaining engine‑relight issues and debris seen on relight.
• Some argue catching at the pad is risky to ground infrastructure; others note payload and mass savings vs. landing legs.

Markets and use cases for Starship

• Extensive discussion on whether there is enough demand for super‑heavy lift:
  • Proponents: large space stations, habitats, very large telescopes, space manufacturing, Starlink deployment, lunar/Mars logistics, and eventual space‑based solar power.
  • Skeptics: current commercial needs are mostly smaller satellites; flagship science missions are rare and already extremely expensive in payload design.
• Several point out that dramatically lower $/kg and bigger fairings could:
  • Make simpler, heavier, cheaper satellites viable.
  • Enable many smaller missions via rideshare.
  • Create entirely new markets that don’t exist at current launch prices.

Human missions, Mars, and risk

• Strong disagreement about Mars colonization:
  • Enthusiasts see Starship as a foundational “railroad to Mars” and argue radiation, ISRU propellant production, and habitat concepts are hard but tractable.
  • Skeptics call near‑term Mars city plans unrealistic, emphasizing radiation, life‑support, psychology, abort options, and huge launch/refueling requirements.
• Some note NASA human‑rating thresholds (loss‑of‑crew probabilities) and expect many flawless uncrewed missions before crewed Earth landings; others suggest using Starship to ferry crewed capsules instead.

Comparisons to other programs & PR

• Multiple comments contrast SpaceX’s rich live visuals, rapid progress, and reuse focus with “old space” (Boeing, SLS, Starliner), which are portrayed as slower, more conservative, and less compelling to the public.
• There is both admiration for SpaceX’s engineering culture and criticism of over‑attributing success to a single executive.

Physics & technical Q&A

• Numerous side threads explain:
  • Reentry heating, terminal velocity, why shallow vs steep profiles are constrained by orbital mechanics and lift/drag.
  • Radiation shielding using mass (especially water), issues of secondary radiation, and Mars surface vs transit exposure.
  • Delta‑v budgets for Moon vs Mars and implications for refueling.

Off‑topic historical debate

• A long sub‑thread drifts into WWII, strategic bombing, nukes on Japan, and WWI causation; participants argue over morality and “Thucydides Trap” dynamics.
  • This is largely tangential to the launch discussion.
