Starship's Third Flight Test [video]

Original Article ↗ Hacker News Discussion ↗

Launch coverage and streaming

  • Many commenters sought non‑YouTube, non‑Twitter/X ways to watch (m3u8/VLC links, embedded stream on spacex.com, alternative YouTube channels).
  • Widespread frustration with Twitter/X’s reliability and UX (login friction, delay, lack of rewind).
  • Multiple people were fooled by fake YouTube “SpaceX” streams showing old launches and crypto scams; criticism that YouTube handles takedowns and spam poorly.
  • Some prefer independent commentary (Spaceflight Now, NASASpaceflight, Everyday Astronaut), while others dislike donation-driven “grifty” styles.

Mission expectations and success criteria

  • Expectations ranged from “likely to explode at some stage” to “orbital velocity and maybe engine relight and reentry.”
  • General consensus: reaching near-orbital speed and performing payload-door and fuel-transfer tests made this a major step forward compared to IFT‑1 and IFT‑2.
  • Many frame the test as a success because Starship demonstrated heavy-lift capability and multiple in-orbit experiments, even though reentry failed.

Orbit vs suborbit

  • Extended debate on whether Starship “reached orbit”:
    • One side: it hit ~26,000 km/h and followed a transatmospheric/elliptical path intentionally intersecting the atmosphere; “close enough” in capability terms.
    • Other side: per calculations and trajectory, perigee remained below Earth’s surface (~‑55 km), so technically suborbital.
  • Agreement that a small additional burn and different trajectory would achieve a stable orbit, but this was intentionally avoided to ensure reentry.

Reentry, relight, and vehicle issues

  • Booster: boostback and partial landing burn worked, but it hit the ocean at ~1000+ km/h; called a “smashdown,” not a soft splashdown.
  • Ship: planned in-space Raptor relight was skipped due to excessive roll; this is seen as a key missing demonstration for controlled deorbit.
  • Reentry: spectacular live plasma views via Starlink; observers saw tumbling/rolling, possible tile loss, and eventual breakup around ~65 km altitude.
  • Some suspect attitude-control issues (RCS performance, icing, leaks) and/or heat-shield damage; all flagged as speculative within the thread.

Subsystem tests: payload door and fuel transfer

  • Payload door: stream showed opening/closing; some later analysis suggests it may not have fully latched correctly. Outcome considered partially unclear.
  • Fuel transfer: internal tank-to-tank cryogenic propellant transfer of several tons was reportedly attempted; callouts claimed success, but final verdict depends on data review.

Reusability, economics, and use cases

  • Many stress that true value comes from reusability and controlled splashdowns/landings of both stages; current system is effectively an expendable heavy launcher.
  • Debate over costs versus Falcon 9 and legacy rockets: some think even expendable Starship could be competitive; others highlight large engine counts and development expense.
  • Discussion of future payloads:
    • Starlink v2 and larger satellites enabled by Starship’s size/mass.
    • Ability to launch ISS‑scale mass in just a few flights vs. dozens historically.
    • Lunar missions: refueling architecture may require 6–15 tanker launches; seen as economically viable only with reuse.

Regulation, FAA, and safety

  • Some accuse the FAA of slowing progress; others argue safety and investigation after IFT‑1’s out-of-control behavior justified caution.
  • Nuanced view: once timelines became predictable, SpaceX aligned readiness with regulatory approval; delays now less constraining than immediately post‑IFT‑1.
  • Safety concerns about uncontrolled Starship reentries: many argue regulators will require demonstrated relight and controlled deorbit before allowing true orbital missions.

Emotional and cultural reactions

  • Strong sense of awe at live HD views of ascent and reentry, compared to historic missions.
  • Multiple commenters describe the event as “sci‑fi made real” and emotionally moving, while others caution against overhyping until reuse and full mission profiles are proven.
