In 2010, eight years after its founding, engineers became stranded on a barge and had to sleep near a spaceship full of gas that could potentially explode, according to Ars Technica senior space editor Eric Berger. Berger, a Pulitzer Prize nominee, interviewed approximately 100 new and former SpaceX employees for his new book Reentry: SpaceX, Elon Musk, and the Reusable Rockets that Launched a Second Space Age.
SpaceX did not immediately respond to The Independent’s request for comment.
After the reusable Dragon spacecraft’s first flight, a SpaceX crew retrieved the spaceship from the ocean in December of that year.
According to Berger, workers immediately checked for fuel leaks. Leaks could mean the risk of explosion, because the fuel inside the Dragon’s Draco engine is made of hypergolic propellant. Hypergolic fuels, like hydrazine, are toxic liquids that react spontaneously and violently when they contact each other. They are used in many different rocket and aircraft systems. They don’t require an external source of ignition, like fire or heat.
An engineer used a 20-foot pole with a tool to detect propellant gases in the air, and no leaks were detected. Using a crane, Dragon was then hauled from the ocean off the coast of Florida and onto a barge.
Two engineers and three technicians wore protective equipment and used independent air supplies as they boarded the barge and began to empty the spaceship’s fuel tanks. Nothing happened, so five workers returned to their nearby crew boat to get some sleep.
But, on the next day and after eight hours draining fuel and storing it in containers, the ocean became rough. It became too dangerous for the workers to return to their boat. They were reportedly stuck overnight with no beds and a toxic Dragon spacecraft.
They had to sleep in a 20-foot-long shipping container next to the Dragon, the book says. Fortunately, crew members on their boat were able to throw them their sleeping bags.
“We got the best night’s sleep we could,” an engineer told Berger. “We were exhausted, so I can’t say that I slept terribly that night.”
They finished emptying the toxic propellant the next day, and the company was given the OK to bring Dragon back on land after depressurizing its propellant system.
Nearly a year later, SpaceX acknowledged there had been a rocket engine anomaly during its launch.
Nearly 15 years later, retrieving the Dragon only takes a few hours. It hasn’t caused explosions. It’s also become a major part of NASA’s space race, ferrying astronauts to and from the International Space Station. Recently, it was used to bring back four Crew-8 astronauts.
