NASA has purchased two seats on Russian Soyuz capsules launching later this year and in early 2018 to expand the crew on the U.S. segment of the International Space Station from three to four, and reserved options to fly astronauts on Soyuz spacecraft in 2019 if commercial rides are not available in time.

The Russian Progress MS-16 cargo freighter rolled out to its launch pad Friday at the Baikonur Cosmodrome in Kazakhstan, its final stop before blastoff Sunday night with more than 5,000 pounds of fuel, food, and water for the International Space Station.
