BREAKING: Pad B Mount Installed! SpaceX Completed Longest Test Ever, But Launch Date Delay...
S35 has officially completed a crucial and successful test in preparation for Flight 9. While there was a slight delay, it looks like the countdown is finally beginning.
Meanwhile, big milestones have been reached across the board. OLM-2 has been fully stacked at Pad B, Booster 14 has arrived at the launch pad, and Test Tank 17 has also taken an important step forward.
And on the other side of the world, China is preparing to launch the next module to expand its Tiangong space station.
Let’s dive into all the latest developments in today’s episode of Great SpaceX.
BREAKING: Pad B Mount Installed! SpaceX Completed Longest Test Ever, But Launch Date Delay...
In the previous episode, we saw S35 roll out to the Massey Test Site after undergoing an engine swap. However, the initial test attempt on May 11 was unexpectedly aborted due to an unspecified issue. Despite that setback, the SpaceX team quickly regrouped and pushed ahead without hesitation.
Just one day later, on the morning of May 12, SpaceX initiated another static fire test with S35. As usual, the vehicle underwent full fueling procedures. The venting from the tanks and vehicle indicated that both liquid oxygen (LOX) and methane were being loaded. While the methane load was lower than LOX, it was noticeably higher than in prior tests, hinting at a longer and more intensive test ahead.

And that’s exactly what happened. Once all systems were checked and ready, the engines roared to life. The thrust was redirected through the flame trench system, designed to protect the test stand and hardware from damage. From the visual output—thick dust clouds and intense engine flames—it’s estimated that all six engines successfully ignited, producing roughly 1,400 tons of thrust.
What stood out the most during this test was its duration. Based on footage and visual cues, the engines appeared to fire for a full minute—making it the longest full-duration static fire for a Starship upper stage to date. For comparison, the previous record was held by S34, which approached the one-minute mark. But S35 clearly crossed that milestone, setting a new benchmark for upper stage testing.
