Musk later said that leaky valves were the culprit and that it would be fixed on the next vehicle. The conversation around far more pressing issues meant that not only did "SN4" receive little coverage, but SpaceX coverage, on the whole, was minimized. Today's static-fire engine test was the fifth for the vehicle, the most of any to date. SpaceX was already building another Starship prototype, the SN5, at the time of today's SN4 failure. So far, both SN1 and SN3 have failed during pressure tests, while SN2 passed. The firm was expected to use the full-size prototype to finally complete a "hop test." ... An "SN4… SpaceX CEO and founder Elon Musk has said that this series of prototypes will be capable of flying to an altitude of around 12.4 miles (20 kilometers) and landing back on Earth. CNBC reported that SpaceX was able to raise $346 million in its most recent funding round.

However, SpaceX had also been planning to install three Raptor engines and a nosecone on Starship SN5 as opposed to the single-engine and no nosecone on SN4. That would have enabled the team to focus on planning for next stages, like sending Japanese billionaire Yusaky Maezawa around the moon by 2023. This has been the company's operating mode during Starship's development -- to rapidly assemble two prototypes at the time to be able to quickly pivot to a new unit if one fails. Its successor SN was lost in similar test in February. Work on the latest iteration of Elon Musk's Mars rocket is progressing rapidly despite some setbacks. That same day, SpaceX received a launch license for its Starship tests from the Federal Aviation Administration. The dramatic explosion of "SN4" ended hopes that it would be the first prototype to complete a small "hop" launch. It's not clear when we might see any of the Starship prototypes leave the ground, but Musk should soon have a quiver of three of the rockets to work with, which will surely help. The comments led to analysis from Teslarati that the explosion was caused by the ground support equipment, where the "quick disconnect" refers to a propellant connection. This miniaturized version of the ship, measuring around 60 feet tall rather than around 400 feet, flew to 150 meters in August 2019. Teslarati estimates that each prototype costs under $10 million to make, a small sum in the grander scheme. This was the first time SpaceX had launched a human, and the first time in nearly a decade American astronauts had entered space from the United States.

America's most successful employee-owned companies, SpaceX's Starship SN4 prototype explodes after rocket engine test. Musk stated in April that the prototype would be "physically ready" for a hop test in a few weeks, and that it would fly 150 meters or 500 feet into the air. Bad weather prevented the Demo-2 mission's initial launch attempt on Wednesday (May 27).

SpaceX successfully test-fired the Starship SN4 vehicle yesterday as part of its preparations for an upcoming launch test that could have carried the rocket about 500 feet (150 meters) up. The feat would have meant SpaceX had reached the same height as it did with the "Starhopper." That could devastate the economy and their lives. Starship SN4 became SpaceX’s first full-scale Starship prototype to pass a cryogenic proof test on Sunday evening at SpaceX’s launch site in Boca Chica, Texas. "Unfortunately what we thought was going to be a minor test of a quick disconnect ended up being a big problem," CEO Elon Musk told Reuters reporter Joey Roulette on Sunday, after leaving the Kennedy Space Center's press site.
