SpaceX’s Crew Dragon is experiencing some major setbacks. The first test flight of the vehicle went without hitch, but further testing of the recovered spacecraft caused some serious issues. During an April 20th test of the SuperDraco engines, the capsule violently exploded. Obviously, this isn’t a great test result for something designed to carry people to space. Humans have a general adversity to explosions. In a statement by the vice president of Build and Flight Reliability at SpaceX, it was revealed that the engines were fired twice successfully, and the capsule then exploded moments before they were fired for the third time. Ignition and firing of the engines involves a lot of valves opening and closing, so it is highly possible that a failure of one of these systems caused the explosion, although nothing will be certain until the investigation is concluded.

However, this isn’t the only failure the program had recently. It was recently revealed before congress that SpaceX had conducted a failed “single-out” parachute test. The test, designed to ensure that the spacecraft could successfully land in event of one of four parachutes failing, ended with the capsule hitting the desert at too high a speed. The test vehicle was reportedly damaged in the incident. These setbacks are bad for the viability of the program as a whole, and will likely mean major setbacks in timing. The first manned spaceflight was scheduled as early as July, but it is no longer likely that this goal will be met. Hopefully, no further setbacks will impede the program’s progress, and the flight vehicle will finally fly with astronauts on-board.
