NASA has admitted that there’s around a 40% chance that tomorrow’s historic astronaut launch could be cancelled.
The mission will see astronauts Robert Behnken and Douglas Hurley launched into space on board a Falcon 9 rocket, on a 400 kilometre journey to the International Space Station.
While the launch is set to take place at 16:33 EDT (21:33 BST) from Kennedy’s Launch Complex 39A, NASA has warned that bad weather could force the space agency to cancel.
The US Air Force 45th Weather Squadron has predicted a 60% chance of unfavourable weather conditions for tomorrow mission.
However, Mike McAleenan, 45th Weather Squadron Launch Weather Officer, says things are looking up.
He said: “It certainly has been trending better over the last day or two for launch weather.
"If I was to issue the forecast today, right now, we would probably be down to 40% chance of violation.”
If the launch does go ahead, the astronauts will be launched into space on board a Falcon 9 rocket, on a 400 kilometre journey to the International Space Station.
Once at the International Space Station, the Crew Dragon spacecraft will dock with the station to test whether it’s capable on future missions of remaining connected for up to 210 days.
Kirk Shireman, manager of NASA’s International Space Station Program, said: “I think the on-orbit crew is definitely ready for some company, and very much looking forward to the launch this Wednesday.
"The ISS team is ready to support the docking of Crew Dragon.”
