Elon Musk SpaceX officially announced this after Starship S36 ”EXPLOSION”… New Data Leaked

SpaceX’s Starship Ship 36 was destroyed last night during a routine static fire test—but what really caused the explosion, and how does this connect to earlier leaks from Ship 34? We now have the most compelling evidence to date, with leaked photos revealing catastrophic Raptor engine failures. Let’s unpack the full story—from the test stand blast to what’s next for the Starship program.


What Happened with Ship 36?

On June 18, 2025, around 11 p.m CT, SpaceX began fueling Starship S36 for a full six-engine static fire test at its Massey test site near Starbase, Texas. The process continued until 11:01 p.m, when the rocket suddenly exploded violently on the stand—a “rapid unscheduled disassembly” in SpaceX terminology, completely obliterating the ship and damaging nearby infrastructure en.wikipedia.org+15cincodias.elpais.com+15thedailybeast.com+15.

Smoke and debris scattered over miles; satellite radar even tracked a chunk of metal flying northwest toward Santa Monica—astonishingly, no injuries were reported . SpaceX confirmed the incident via a post on X:

“On Wednesday June 18th at approximately 11 p.m CT… the Starship preparing for the 10th flight test experienced a major anomaly while on a test stand at Star Base. There are no hazards to residents… safing operations continue.”

The event, captured on livestream, showed a massive fireball and stunning levels of destruction timesofindia.indiatimes.com+3news.com.au+3nypost.com+3en.wikipedia.org+1nypost.com+1.


Signs of a Root Cause: Shared with Earlier Flights

Leaked Photos from Ship 34 Now Illuminate Patterns

Three months ago, during Flight 8 in March, a catastrophic upper-stage failure destroyed Ship 34. Now, leaked internal photos show a vacuum Raptor engine torn apart—its nozzle split, internals shredded—evidence of an extreme engine-level explosion moneycontrol.com+15en.wikipedia.org+15reddit.com+15.

Visuals suggest propellant mixing or line ruptures: blurred imagery hints at smoke or vapor leaking near sea‑level engines moments before destruction. Onboard camera footage from Flight 8 corroborated this—with flames appearing at T+7:45, followed by engine shutdowns by T+8:05, loss of control, then vehicle breakup en.wikipedia.org.

Technical Breakdown: Combustion Instability

Evidence suggests combustion instability—an uncontrolled ignition due to a faulty mixture of liquid methane and oxygen in either Ship 34 or S36. These pressure “spikes” could rupture welds or fuel lines, leading to engine flare-up.

According to SpaceNews and NASAanalysis:


FAA Investigation & Ongoing Fixes

The FAA closed its investigation into Flight 8 on June 12, acknowledging that SpaceX implemented eight corrective actions—updated fuel lines, temperature controls, venting, and nitrogen purges reddit.com+2en.wikipedia.org+2fox4news.com+2. Despite those changes, structural vulnerabilities persisted in upper-stage systems.

SpaceX also performed over 50 long-duration Raptor firings at the McGregor facility to test durability under different conditions. For S36, the revised engine design includes reinforced joints, improved venting, and a nitrogen purge for idle fuel lines to prevent mixing .


A Broader Pattern of Iterative Space Testing

This is one of multiple Starship setbacks in 2025:

SpaceX’s “fail fast, fix fast” approach continues—each failure feeding data loops into the next design, engine variant, and system upgrade cycle. This method, though painful, shortens the learning curve and accelerates progress toward reusable Starship systems .


What’s Next? Ship 37 Takes the Mantle

Following S36’s destruction, Ship 37 is the next candidate for Flight 10. As of June 16, Ship 37 was transferred to Mega Bay 2, its heat shield tiles ~70% installed, and at least one vacuum engine moved in for integration en.wikipedia.org.

SpaceX will likely delay Flight 10 into early August, allowing for:

  1. Post‑blast site cleanup and test stand repair.
  2. FAA safety clearance for five-foot fallow.
  3. Engine and structural upgrades in S37.

Elon Musk has hinted future launches “nothing so far suggests pushing the next launch past next month” economictimes.indiatimes.com.


Why This Matters: Reusability and the SLS Contract

The stakes are high: SpaceX has a $2.9 billion human landing system contract with NASA. Starship must clear reliability hurdles to transport astronauts to the Moon and Mars.

As analyst Will Lockett noted, boosters still face a dilemma—reinforce for reuse or accept fragility, which could defeat the economic model . Upper‑stage leaks, COPV issues, and pressure instability show there are still systemic weaknesses to address.

However, SpaceX has successfully iterated through three flights this year, rebuilding after each failure and continuing toward weekly launch cadence goals en.wikipedia.org+1theverge.com+1cincodias.elpais.com.


Flight 10: A Crucial Turning Point

Successfully flying Ship 37 could dramatically shift Starship’s trajectory:

  • Demonstrate major fixes at scale
  • Restore confidence in reuse costs
  • Rebuild site and regulatory momentum

On the other hand, another failure could force more fundamental design changes, delaying crewed Moon/Mars missions and straining industry timelines.

Final Analysis

SpaceX is pushing the envelope of rocket engineering with rapid iteration. The Ship 36 explosion, while dramatic, fits into a pattern: fast-paced testing, failure, learning, adaptation. The leaked photos from Ship 34 provide a chilling look at the internal violence of engine failures, guiding engineers on what to fix.

With Ship 37 nearing readiness and FAA inspections reopening, Flight 10 will be a critical indicator. Will the fixes hold? Can COPV upgrades, venting systems, and engine reinforcements survive?

For fans of Mars missions and booster reuse, the next few months will be vital. The vision is bold: a reusable spacecraft system that lowers cost, increases launch frequency, and enables the next age of human spaceflight. SpaceX’s approach may be messy, but as the old adage goes: “Success comes from what we learn.”

FAQs

1. What caused the explosion of Starship Ship 36?
Ship 36 likely exploded due to a pressurization failure or propellant leak in the upper section during fueling. Some reports suggest a COPV failure or combustion instability involving liquid methane and oxygen.
