Engineers investigate another malfunction on SpaceX's Falcon 9 rocket
SpaceX is investigating a malfunction with the Falcon 9 rocket's upper stage, which reentered the atmosphere outside the designated area. They will not resume launches until the cause is identified.
Read original articleSpaceX is currently investigating a malfunction that occurred with the Falcon 9 rocket's upper stage during a recent launch. The issue caused the upper stage to reenter the atmosphere and land in the ocean outside of its designated disposal area after successfully deploying the Crew Dragon spacecraft, which carried NASA astronaut Nick Hague and Russian cosmonaut Aleksandr Gorbunov to the International Space Station. The Falcon 9's second stage engine performed as expected initially, but a problem arose during a planned deorbit burn, leading to an off-nominal trajectory. SpaceX has stated that they will not resume launches until they understand the root cause of the malfunction. This incident marks the third grounding of the Falcon 9 in less than three months, following a previous failure in July that resulted in a payload being stranded in a lower orbit due to a liquid oxygen leak. Experts suggest that the recent issue may be related to a slight underburn of the Merlin vacuum engine, which could have caused the rocket to veer off course.

The FAA care about safety. If you have anything falling back to Earth you have to prove it is safe. That usually means you have to do some analysis to show your chance of killing someone on the ground is less than 1 in 10,000 (that's the European level, I believe the US level might be tougher).
An easy way to meet this is to land in the middle of the ocean, since there's a lot of space and very few people around, hence SpaceX target the Pacific for the falling second stage.
As part of this you need to identify your expected landing zone, which is then used to warn sailors and aircraft about the risk. But also this is not really enforced - nobody goes out there to check the zone is empty before the launch is authorised, like they do around the launch pad.
But you also need to account for failures in your 1 in 10,000 analysis. So as part of it you look at the probability of something failing and of pushing you off track, and then the risk of killing someone if that happens. Again, this is easy if you are targeting the ocean, since being even a thousand miles off still brings you down in empty water.
So this scenario, where the upper stage fails and comes down in the wrong place, is almost certainly already included in SpaceX’s planning and licensing.
Where the FAA might have questions is whether the probability of failures is correct, or if something has changed in manufacturing to make them more likely.
For SpaceX, obviously, a dodgy second stage is a bigger problem. They need the stage to be reliable for upcoming interplanetary flights and others going beyong LEO. And they'll want to understand what caused it in order to make sure it couldn't happen earlier (which in this case could have been while astronauts were still attached).
So there's a good reason SpaceX are investigating and already announced a pause in flight, and probably a good reason too why the FAA is keeping quiet so far. Behind the scenes I'm sure they're already in contact about the matter.
Please, for the love of humanity, do your part and donate as much money as you can to Elon Musk so he can save us all.
