Elon Musk: Starship prototype could explode from helium entering engine

March 10, according to the Russian Sputnik website reported that American entrepreneur and founder of SpaceX and Tesla Elon. Mr Musk said helium gas entering the engine was likely to have caused the explosion of the Starship prototype after it landed smoothly.

Last week, SpaceX’s prototype “Starship” rocket, designed for manned space flights, exploded minutes after it lifted off from a Texas test site and landed without incident.

“SN10 engine thrust is low (possibly) due to entry of some helium in the tank,” Musk tweeted. The impact force at 10 meters per second destroyed the support and part of the skirt.” He emphasized that some modifications will be made when the SN11 trial is carried out.

On March 4, the SN10 prototype was successfully launched after two failed attempts. It climbed to an altitude of about 10,000 meters, and is believed to have completed fuel replacement, steering and a controlled descent. It started the engine again before landing and landed successfully.

This is the third time that a starship has been sent to an altitude of more than 10,000 meters, the report said. Previous launches on Dec. 10, 2020, and Feb. 3, 2021 both exploded and disintegrated on landing, but the tests were still considered successful because the main objective was not to land, but to check the movements of the rocket in the air: steering, maneuverability while gliding toward the surface, and the performance of the systems. Even before liftoff, Musk had estimated that there was only a one in three chance of a successful landing on the first launch.

SpaceX is reportedly developing a transport system consisting of a reusable Super Heavy rocket and a “starship” to deliver satellites, people and supplies to Earth orbit, the moon and Mars. (APP)
