In this case, SpaceX is planning to send the tourists to space in a Dragon 2 spacecraft currently under development, with its
first uncrewed test flight planned for this summer, and its first flight to the International Space Station planned for late this year.
Each company will conduct
an uncrewed test flight followed by a crewed test flight.
In December 2014, the spacecraft launched atop a United Launch Alliance Delta IV Heavy rocket on
an uncrewed test flight to Earth orbit.
As noted on Ars Technica, both Boeing and SpaceX have expressed confidence that
uncrewed test flights would begin before the close of this year (2018), according to the Ars Technica report, a U.S. House Subcommittee on Space hearing cast doubt on these assertions.
In October 2016, citing development and production concerns, Boeing spokesman William Barksdale stated that the company would delay its pad abort test from October 2017 to January 2018, with
the uncrewed test flight moving from December 2017 to June of 2018.
The rocket would carry crews in the agency's Orion space capsule, which has made one
uncrewed test flight.
NASA plans to certify the company's vehicles only after they've done
an uncrewed test flight and a crewed test flight, meaning the first astronauts likely won't fly until late next year at the earliest.
