All eyes are pointed to the sky, looking at the weather, which remains the main obstacle so far to the historical Space X’s launch (why it is so crucial, anyway? read this). The launch had to be cancelled (‘scrubbed’) on Wednesday at T-17 due to bad weather and the new go-date was set for today, Saturday (May 30) at 3:22 p.m. EDT (1922 GMT).
The launch time is a fixed variable of the equation, and it changes each day, linked as it is to the when the Earth’s rotation brings pad 39A (where Falcon rocket is standing) under the orbital ground track of the International Space Station.
Today forecasts don’t look too good either, and it is not unlikely for the launch to be postponed again. There are a series of considerations to be taken into account for a second-attempt decision. In case of success, the capsule will dock with the ISS about 19 hours after launching, for a long stay of 119 days before returning home. Fingers crossed!
