A qualification take a look at of a Raptor 2 engine has resulted in a dramatic explosion at SpaceX’s McGregor facility. The firm has but to touch upon the incident, nevertheless it’s unlikely to have an effect on the upcoming fourth take a look at launch of the Starship megarocket.
The incident occurred on Thursday at round 4:15 p.m. native time at SpaceX’s Rocket Development and Test Facility in McGregor, Texas. Video footage from NASASpaceflight captured the mishap, displaying the Raptor engine shutting down roughly 14 seconds after ignition. Following the shutdown (which seemed to be regular), vapor continued to linger and dissipate beneath the engine, however a small hearth then appeared on the backside of the testing stand. The flames grew and traveled upwards, culminating in a huge fireball that engulfed all the tower.
SpaceX has not but commented on the incident, and it’s unclear if the blast triggered any injury to the Raptor engine or the take a look at stand. The seemingly gasses concerned within the explosion are methane and oxygen. SpaceX’s Raptor engine makes use of liquid methane (CH4) as its gas and liquid oxygen (LOX) as its oxidizer. If there was a leak or combustion anomaly, these gasses may combine and ignite, leading to a sort of fuel-air bomb that created the blast seen on Thursday. That one thing might need exploded on the take a look at stand on account of the fireball is one other chance, however we’ll have to attend for SpaceX to supply extra particulars.
Although the occasion was dramatic, anomalies throughout qualification checks do occur. SpaceX runs qualification checks of its engines previous to incorporating them into operational rockets to make sure they meet efficiency and security requirements. SpaceX is at the moment testing Raptor 2 engines, which characteristic improved efficiency, greater effectivity, and larger reliability in comparison with their predecessors.
It’s unlikely that this incident will delay IDF-4, the upcoming fourth launch of SpaceX’s experimental Starship megarocket, which makes use of Raptor engines. The firm carried out a moist gown rehearsal of the launch system on May 20, with firm CEO Elon Musk tweeting that “Starship Flight 4 [should happen] in about 2 weeks,” which must be across the first week of June.
