Blue Origin, the commercial space company bankrolled by Amazon.com founder Jeff Bezos, plans to begin unmanned orbital flight tests of its biconic-shape human capsule in 2018. Ultimately, the company will use an orbital launch vehicle powered at least in part by a clean-sheet cryogenic engine it now has demonstrated can support suborbital human spaceflight.

Initial flights of the seven-seat orbital human vehicle—so far known only as “Space Vehicle”—are scheduled to go on the Atlas V, which has also been the choice of other companies vying for a NASA contract to transport crews to the International Space Station.
