First privately-funded trip to orbit going well, but details few and far between

The first all-civilian, privately-funded crew to reach orbit came through their initial hours in the weightless environment of space "healthy, happy and resting comfortably," SpaceX reported Thursday.

Company founder Elon Musk tweeted: "Just spoke with (Inspiration4) crew. All is well."

But no immediate word on what they talked about or any details about the progress of the historic mission.
