TIMELINE: Inspiration4 crew schedule leading up to launch

At 8:02 p.m. Wednesday night, four people are scheduled to blast off from Florida on a 3-day mission to space on the first all-civilian crew. 

They spent many months and hours learning how to fly the Crew Dragon capsule for the Inspiration4 mission and doing simulations like getting suited up and doing a 30-hour test inside the capsule.

"We are doing everything for the first time. We are writing a couple of them, breaking a couple of them that NASA used to demand. Well, we get to kind of do things our own way," said Chris Sembroksi.

A CEO, cancer survivor, engineer, and professor are all writing new rules for space travel. Each of them is bringing something different to the space table.
