SpaceX is once again preparing to make history – the private spaceflight company is set to launch its Crew Dragon Demo-2 mission in collaboration with NASA today. This is the second time they’ve prepared to launch this mission, after an attempt on Wednesday last week was scrubbed due to bad weather. Today’s attempt is set for 3:22 PM EDT (12:22 PM PDT) and preparations, along with the launch itself, will be streamed above starting at 11 AM EDT (8 AM PDT).

The launch will take off from Cape Canaveral in Florida, and once again weather is a concern for today’s launch window. SpaceX and NASA have an instantaneous launch window today, which means they only have the one shot to take off – if the weather isn’t cooperating at 3:22 PM EDT, they’ll have to re-attempt the launch again, with the next possible window set for tomorrow, Sunday May 31.
