Elon Musk just Reacted To Booster 7 Engines Firing, Booster 8 Moved To OLM

Elon Musk Just Reacted On Starship Booster 7 Engine Firing, and What Next For Booster 7.

On September 19, SpaceX continued testing of its Super Heavy Booster 7 stainless-steel vehicle. It’s engines were fueled with cryogenic liquid methane (CH4) and liquid oxygen (LOX). Only 7 Raptor V2 engines out of 33 were ignited on Monday afternoon.

However, this is a great milestone because it is the first time ever they ignite seven engines simultaneously. During Booster 7’s previous static-fire test on August 31st, only 3 engines were ignited.

“Chamber pressure looked good on all 7 engines,” shared Musk via Twitter soon after the test. NASASpaceflight shared a video of the brief engine ignition, linked below.

When asked about when SpaceX will perform a static-fire test of all 33 Raptor V2 engines simultaneously, Musk said the rocket will now undergo more preparations at the Starbase factory. “Booster 7 now returns to high bay for robustness upgrades & booster 8 moves to pad for testing,” said Musk, “Next big test is probably full stack wet dress rehearsal, then 33 engine firing in a few weeks.”

Few Days Ago, SpaceX workers replaced one of the center engines, specifically engine number seven, from Booster 7. This raised some eyebrows as the engine was not tested during the test campaign of the booster and wasn’t involved in the previous static fire tests.

Work on these issues would follow over the next week until Sept. 8. That day, both booster and ship were tested again, this time with a 33-engine spin prime test of Booster 7 and a six-engine static fire test of Ship 24 that lasted about six seconds.

  1. My concern about the starship system is the reliability of the raptor engines. It seems that after most tests, an engine has to be removed for service. Maybe, and hopefully, this is a normal thing in the development of a rocket engine, and any glitches will be fixed by the time the booster finally launches.

  2. A flame trench is the only solution. Concrete chips will be flying everywhere. Chips will hit the engines.
