New launch time for Bob and Doug
If you want to watch the second attempt to launch SpaceX and Crew Dragon live on NASA TV, the scheduled launch time is 20.22 on Saturday. You've seen how fast the ISS travels (5 miles per second) and that is the reason if the launch is not at the exact time, the astronauts would not be able to catch up with ISS and the launch has to be put back.
You need patience for Astronomy! One of the first rules. You can control all the technology and personnel but sometimes the weather just doesn’t play ball! Let’s hope at GO/NO GO on Saturday we hear “You are good to go Bob and Doug”.
