SpaceX launches Starship v3 rocket
SpaceX’s latest test flight of its Starship v3 prototype reached orbit, deployed dummy Starlink payloads, survived engine failures, and executed a controlled ocean splashdown, showcasing major progress in heat shielding, guidance, and upper-stage reuse. Commenters weigh this technical success against concerns over recurring engine issues, the pace and cost of Starship’s highly iterative development, and whether it can mature in time to support NASA’s Artemis lunar plans. The broader implications for SpaceX’s business model, from Starlink economics to a potential IPO and military or commercial uses of ultra‑cheap heavy launch, are also key points of debate.
Flight Overview & Outcomes
- V3 Starship launched successfully after a ground-equipment scrub.
- One booster engine and one ship vacuum engine failed; despite this, ship reached (near-)orbit, deployed dummy Starlink payloads, and executed controlled reentry with a soft ocean splash near a buoy.
- Booster relight for boostback failed; it later lit some engines for a landing burn but appears to have hit the water hard and was destroyed.
- Some commenters say the booster was “very off target”; others say it was on or near the planned splash zone – exact accuracy is unclear.
Engines, Hot Staging, and Vehicle Behavior
- Raptor 3 is a major redesign (integrated, 3D‑printed plumbing, new shielding, more thrust and efficiency).
- Observers debate whether engine outs were expected tests or reliability problems; rough back-of-envelope stats on 2 failures out of 39 engines give a very wide uncertainty range.
- Discussion and corrections on engine-out capability: ship’s center “sea-level” engines can gimbal and were used to compensate for loss of a vacuum engine.
- Hot staging and aggressive post‑separation flip may be causing propellant slosh and downcomer/feeder issues; seen as a plausible cause of booster problems but not confirmed.
- Question raised about whether the benefits of hot staging justify complexity; answer given that any throttle-back costs velocity you never recover.
Reentry, Heat Shield, and Reusability
- Reentry is widely viewed as the biggest success: no obvious hot spots or burn‑throughs, smoother than V2 flights.
- Some worry about visible cracking of heat shield tiles and the challenge of rapid turnaround; others note tiles are designed to ablate, be easily replaced, and that damage appeared modest compared to earlier flights.
- Comparisons with Shuttle highlight that turnaround time and refurbishment cost remain open questions for Starship.
Video, Telemetry, and Data
- Strong praise for SpaceX videography: high‑res engine-bay views, booster flip, plasma during reentry, dummy payloads burning up.
- Complaints that mainstream/NASA feeds often miss “the good shots.”
- Commenters note enormous accumulated test data from thousands of Raptor firings and rich telemetry, including ground test stands with hundreds to thousands of channels.
Iterative Design vs. “Boondoggle”
- One camp sees 12+ explosive/partial-success flights and continual redesigns as evidence Starship risks becoming another overcomplicated boondoggle.
- Others argue:
- V3 is the first payload‑intent configuration; earlier ships were testbeds.
- Many flights in a short time at relatively low cost represent strong progress compared to traditional programs (e.g., SLS).
- Large test-flight counts are normal for cutting‑edge hardware and enable higher eventual performance.
- Debate over starting with such a huge vehicle: some argue a smaller “Falcon‑scale” Raptor testbed would have been cheaper; others say schedule pressure and ultimate goals justify going full scale.
Economics, Funding, and IPO
- Thread cites >$15B already spent on Starship and emphasizes that Starlink/direct‑to‑device telecom is currently the only clearly large market to recoup this.
- Back‑of‑envelope comparisons to Falcon 9 cost per launch and number of Starship flights needed to break even; figures vary and are speculative within the thread.
- Concerns raised about SpaceX’s broader financial exposure (Starship, Starlink, xAI, Twitter) and that Starship economics depend on very high launch cadence and massive payloads.
- Some note potential military applications and other long‑term use cases (asteroid mining, rapid global transport, lunar/space infrastructure), while others counter that orbital mechanics and costs make many such visions uneconomic with current tech.
- IPO discussion: worry that public markets punish scrubs/failures; others reply that control structure will likely let management prioritize long‑term goals.
Artemis, Timelines, and Mission Risk
- Several comments link Starship progress to NASA’s Artemis lunar lander schedule.
- Concern that continued issues with engines, refueling, and full reuse may delay uncrewed and crewed lunar landings beyond current targets.
- Some propose a rough sequence: demonstrate reliable reentry and reuse, then in‑space relight and refueling, then uncrewed lunar landing, before crewed attempts.
Safety, Culture, and Ethics
- Critical comments highlight worker deaths and hundreds of injuries at SpaceX test facilities, portraying Musk as too willing to accept human risk.
- Others contextualize industrial fatalities against historical mega‑projects and argue that dangerous pioneering work inevitably carries some risk.
Overall Sentiment
- Strong enthusiasm about visuals, reentry performance, and engine‑out resilience.
- Persistent skepticism about reliability, rapid reusability, cost recovery, and schedule realism.
- Broad agreement that Flight 12 showed meaningful forward progress, with engines and booster recovery now seen as the main technical weak points.
