Axios space reporter Miriam Kramer goes inside SpaceX's headquarters in Hawthorne, California, to see the factory floor, the Inspiration4 crew's training regimen and how this mission fits into SpaceX's broader goals.

Kramer speaks with SpaceX senior leadership and tours the facility, culminating in a chance to see a brand new bubble window built specifically for the Inspiration4 crew.

She gets to sit in on the crew training in a cockpit simulator and learn about the various scenarios they are learning to anticipate.

She also peers inside the Dragon capsule simulator — a mock-up of the capsule they'll fly in — and hears the crew's testimony of a harrowing 30-hour simulation of their mission as the capstone of their training.
