The launch may happen as early as eight:02 p.m. But the motion will start hours earlier than that.
If the schedule is much like SpaceX’s earlier NASA astronaut flights, then about three and a half hours earlier than the launch, the crew will start donning their custom-made SpaceX spacesuits. Once technicians have confirmed the fits are correctly fitted, the 4 astronauts will say goodbye to their households and be transported to the launchpad.
Approximately two and a half hours earlier than the flight — round 5:30 p.m. Eastern time — the crew will board the Crew Dragon capsule. SpaceX technicians will then full quite a lot of procedures earlier than sealing them inside the spacecraft, a course of that would take about an hour.
About 45 minutes earlier than the scheduled launch time, SpaceX will begin loading propellent into the rocket and start making closing checks of the spacecraft’s techniques and the climate to determine whether or not it’s secure for the mission to launch.
Once the rocket launches, the capsule will start a collection of steps to be lifted to orbit, together with separating from the rocket’s first and second phases. In the hour or in order that follows, the spacecraft will hearth its thrusters, setting it on the course it’s going to observe till the astronauts return to Earth on Saturday.
