Why has the SpaceX launch been delayed?
Bad weather has prevented the first launch of NASA astronauts from US soil in nine years.
The SpaceX capsule is now due to attempt lift-off on Saturday.
A tweet from US-based space agency NASA wrote: “We are not going to launch today.”
“Due to the weather conditions, the launch is scrubbing.
“Our next opportunity will be Saturday, May 30.”
At 9.20pm BST (4.20pm ET), the countdown clock was held at t-minus 16 minutes and the flight was confirmed as grounded.
SpaceX’s launch commander officially scrubbed the launch under safety rules around weather conditions.
Apparently, it was the high chance of lightning that proved fatal for Demo-2.
If commanders had been able to delay the launch by ten minutes, it could have gone ahead, but unfortunately this was not possible.
