CAPE CANAVERAL, Fla., Sept 15 (Reuters) – The latest in a recent line of space-obsessed billionaires was set for liftoff on Wednesday with three less wealthy private citizens along for the ride aboard a SpaceX rocket ship, seeking to become the first all-civilian crew launched into Earth orbit. They will fly aboard a gleaming white SpaceX Crew Dragon capsule, dubbed Resilience, perched atop one of the company’s reusable Falcon 9 rockets and fitted with a special observation dome in place of the usual docking hatch. Despite some largely honorary titles, the Inspiration4 crew will have no part to play in flying the spacecraft, which will be operated by ground-based flight teams and onboard guidance systems, even though two crew members are licensed pilots. Biomedical data and biological samples, including ultrasound scans, will also be collected from crew members before, during and after the flight.
