The next three-person crew will launch to the International Space Station sometime between July 23 and July 25 after a two-month delay triggered by the failure of an unmanned Progress resupply mission in April, Russian officials said Tuesday.

Russian Soyuz commander Alexander Misurkin and two U.S. astronauts — flight engineers Mark Vande Hei and Joe Acaba — lifted off Tuesday from the Baikonur Cosmodrome in Kazakhstan. The trio began their six-hour journey to the International Space Station with a launch aboard a Soyuz rocket at 2117 GMT (5:17 p.m. EDT), and docking occurred at 0255 GMT (10:55 p.m. EDT).

America’s most experienced astronaut says her fully commercial visit to the International Space Station this week is a critical stepping stone on the road to space tourism, private-sector orbital research and development of commercially operated space stations.
