I think I heard them mention a computer that hadn't come up properly. Still, they have a reputation for fixing things quickly.
I thoroughly enjoyed watching their first mission where their programmers made changes while the craft was sitting outside of the ISS because the position markers weren't being spotted as they expected. They do have an amazing ability to change on the fly, not what you expect from a space program except in SciFi
Now they're trying again! T minus 13 minutes! So cool!
OMG so so so cool
Held, reset to T-13m. They have an hour+ long launch window so they have a good chance of lauching today.
Edit: clock is counting down again, launch estimated to be 3:30pm PST.
66 minute launch window through 6:43PM ET. T-13 cycle must start no later than 6:30PM ET.
