On Saturday, @NASA will attempt to send into orbit a spacecraft designed to transport astronauts, a feat it hasn’t tried since retiring its space shuttles in 2011.⠀
⠀
The initial demonstration flight of @spacex's Dragon capsule won’t carry people, but is intended to test life-support and other systems for astronauts.⠀
⠀
For eight years, NASA has relied on buying rides aboard Russian rockets and capsules, with the price tripling over roughly a decade to some $80 million a seat.⠀
⠀
Depending on how many trips U.S. replacement capsules will make annually, and the number of astronauts on board, NASA estimates the price tag of Crew Dragon flights at less than $60 million a seat.⠀
