After Wednesday's cancellation - the clear weather means Irish people should be able to see the NASA SpaceX rocket soaring across the skies on Saturday night.
All will depend on the weather in Florida but hopefully the rocket with two astronauts on board will launch at 8:22pm Irish time.
If skies stay clear and all goes to plan you should be able to see the craft under the moon in the south-west about 10-15 minutes later as it enters space.
However it will depend on weather across the Atlantic, after concerns yesterday that the mission could be cancelled due to unfavourable conditions.
If all goes to plan, the Falcon 9 rocket will take off from launchpad 39A at the Kennedy Space Centre in Florida and journey to the International Space Centre.
The mission is being touted as Elon Musk's biggest project yet, as the Space X founder looks to make history with its first-ever human flight.
Mr Musk tweeted a photo of the rocket framed by a stunning sunset the night before the mission.
While astronauts are regularly launched from Earth to the International Space Station, these launches don’t usually take place in the US.
Interestingly, if the SpaceX rocket was to abort its takeoff, it could land just off the west coast of Ireland.
NASA state: "Once liftoff occurs, the abort landing locations change with every passing second of flight, ultimately resulting in Crew Dragon requiring a potential landing off the western coast of Ireland."
The astronauts will fly to the International Space Station, where 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.”
