ISS Exp 71 to Welcome 1st Crewed Starliner and Dream Chaser Demo Missions in Summer

Newly commenced ISS Expedition 71 is underway with Cosmonaut Oleg Kononenko continuing command from Exp 70, and crewmates Nikolai Chub, Matthew Dominick, Michael Barratt, Jeanette Epps, Alexander Grebenkin, and Tracy Caldwell-Dyson. The 6-month Exp 71 mission is planned to perform 6 extravehicular activities (EVAs) – the first of which will be a 7-hour Russia spacewalk #62 on April 25. Currently there are 6 craft docked at ISS: Soyuz MS-25 crew ship, SpaceX Dragon crew 8 Endeavour, SpaceX Dragon cargo SpX-30, Northrop Grumman Cygnus NG-20 space freighter S.S. Patricia “Patty” Hilliard Robertson, and the Progress 86 and 87 resupply ships. During Exp 71, more cargo will arrive via Progress 88 and 89, as well as Cygnus NG-21. The Boeing Starliner CST-100 Crew Flight Test is now set to launch May 7, carry Barry Eugene Wilmore and Sunita Williams, and remain docked for 6 days. It will be the first crewed flight of Starliner which is designed to carry 4 crew and 100 kg of cargo to ISS, with a 210-day docked design life and reusability up to 10 times. First launch of Dream Chaser Tenacity (Sierra Nevada Corp. Demo-1 mission), under the NASA Commercial Orbital Transportation System program, is slated for June. The system features the Shooting Star expendable cargo module (capacity 4,536 kg, unpressurized) and the Dream Chaser reusable cargo craft (return capacity 1,750 kg, pressurized).
