NASA Astronaut Nicole Stott, wife of Manxman and boss of space company ManSat Chris Stott, will be hoping to make into orbit at last this evening.
After two delays this week due to the weather and technical problems, it’s hoped Space Shuttle Discovery can be launched late tonight.
The shuttle is on a mission to the International Space Station, but there have been problems with a fuel valve and then thunderstorms over Canaveral in Florida.
If the launch doesn't take place this week it will have to be delayed until later next month.
