SpaceX experienced a setback yesterday. Apparently the Dragon capsule that recently returned from space, exploded.
They had it sitting on the launch pad for tests. Not sure what happened yet. Space X is pretty hush-hush about this, and already trying to cover up the leaked video by deleting the original tweet. They are calling this an "anomaly."
Initial data reviews indicated that the anomaly occurred approximately 100 milliseconds prior to ignition of Crew Dragon’s eight SuperDraco thrusters and during pressurization of the vehicle’s propulsion systems. Evidence shows that a leaking component allowed liquid oxidizer – nitrogen tetroxide (NTO) – to enter high-pressure helium tubes during ground processing. A slug of this NTO was driven through a helium check valve at high speed during rapid initialization of the launch escape system, resulting in structural failure within the check valve. The failure of the titanium component in a high-pressure NTO environment was sufficient to cause ignition of the check valve and led to an explosion.
“Government has three primary functions. It should provide for military defense of the nation. It should enforce contracts between individuals. It should protect citizens from crimes against themselves or their property. When government-- in pursuit of good intentions tries to rearrange the economy, legislate morality, or help special interests, the cost comes in inefficiency, lack of motivation, and loss of freedom. Government should be a referee, not an active player.” - Milton Friedman
