Washington, April 16 : US space agency NASA is set to launch SpaceX Crew Dragon second flight to the International Space Station on April 22, it said. The Crew-2 with four astronauts on board, will lift-off at 6:11 a.m. EDT on April 22, from Launch Complex 39A at the agency's Kennedy Space Center in Florida. The Crew-2 flight will carry NASA astronauts Shane Kimbrough and Megan McArthur -- whoa-will serve as the mission's spacecraft commander and pilot, respectively -- along with JAXA (Japan Aerospace Exploration Agency) astronauta-Akihikoa-Hoshidea-and ESA (European Space Agency) astronaut Thomasa-Pesquet, whoa-will serve as mission specialists to the space station, the space agency said in a statement. The mission is the second of the six certified, crew missions NASA, and SpaceX will fly as a part of the agency's Commercial Crew Programme. Crew-1 successfully docked into the ISS in November, last year. The Crew-2 astronauts will remain aboard the space station for approximately six months as expedition crew members, along with three crewmates who will launch via a Russian Soyuz spacecraft. The increase of the full space station crew complement to seven members -- over the previous six - will allow NASA to effectively double the amount of science that can be conducted in space, NASA said. /IANS
