The next starting point is Saturday at 3:22 p.m. ET, with a backup window from 3pm ET on Sunday.
“The main problems are flight through precipitation and the anvil and cumulus cloud rules associated with afternoon convection,” the official weather relay forecast predicted Thursday morning.
On Wednesday there was a 50/50 chance the weather would clear and an additional 10 minutes might have given the starting team the go-ahead. But the timing had to be just right for a real rendezvous with the International Space Station.
“The weather is the only thing we can̵
During this time of year, it is not uncommon for a sea breeze along Florida’s east coast to cause thunderstorms in the afternoon.
It is not always easy to predict exactly where one of these storms will appear. Nevertheless, forecasters can use the overall pattern to determine whether conditions for the development of thunderstorms arise.
Sunday also has rain chances in the forecast, albeit a little less than Saturday, Brink said Thursday. The weather squadron also has a 40% chance of favorable conditions on Sunday.
Missile-controlled flashes are a danger of starting
An entire team of meteorologists from the 45th Space Wing and SpaceX is on site to determine whether the weather will scrub the launch. As on Wednesday, the decision can be made until the start.
A disappointment was evident during NASA’s Wednesday show when the weather team called it a no-go for launch.
For example, a flight is stopped by lightning in the area, as is a cloud with a sufficiently large electric field to generate a lightning-triggered lightning. This happens when a huge spark of electricity occurs when a large rocket flies through a sufficiently strong atmospheric electric field.
The electrical field required to fire a missile-triggered flash is much less than that of a natural flash.
“Any type of lightning could seriously damage the missile and pose a threat to public safety,” explains the weather squadron.
Forecasters also need to monitor the winds.
If there is a sustained wind of 30 mph or more at 162 feet above the launch pad, the mission will be canceled.
The weather squadron must also monitor the weather distance, because if the Crew Dragon capsule encounters a problem, it must have a safe spraying location.
