欧美文化:First U.S. private astronaut mission to space station returns to Earth

LOS ANGELES, April 25 (Xinhua) -- The first U.S. private astronaut mission to the International Space Station (ISS) returned to Earth on Monday.

The SpaceX Dragon spacecraft splashed down off the coast of Jacksonville, in the southeastern U.S. state of Florida, at 1:06 p.m. Monday Eastern Time, SpaceX confirmed.

The crew undocked from the ISS at 9:10 p.m. Sunday Eastern Time, completing the first all-private astronaut mission to the orbiting laboratory.

The four-person multinational crew is composed of Commander Michael Lopez-Alegria and Pilot Larry Connor of the United States, Mission Specialist Eytan Stibbe of Israel, and Mission Specialist Mark Pathy of Canada.

"The success of this first private astronaut mission to the International Space Station is an important step in opening opportunities for space travelers and achieving NASA's goal of enabling commercial business off the planet in low-Earth orbit," said NASA Administrator Bill Nelson.

"This progress has been made possible by NASA's work with private industry - especially the Commercial Crew Program," he said.

The mission, codenamed Ax-1, was launched on SpaceX's Falcon 9 rocket from NASA's Kennedy Space Center in Florida on April 8.

The crew spent 15 days in orbit, conducting a variety of science experiments and technology demonstrations, including research on cancer cell growth, a demonstration testing a new air purifier for station use, and a study utilizing swarms of autonomous tiles for future applications of in-space construction, according to NASA.

Following the splashdown, teams will retrieve science aboard the Dragon spacecraft and transport it to nearby Kennedy Space Center for further investigation.
