MIAMI: NASA astronauts entered the International Space Station on Sunday after a landmark 19-hour journey on the first crewed US spacecraft in nearly a decade.
The arrival completed the first leg of the trip, designed to test the capabilities of the Crew Dragon capsule by SpaceX. The mission will only be declared a success when the astronauts return safely to Earth in a few months’ time.
The spaceship’s hatch opened as Bob Behnken and Doug Hurley carried out final procedures before crossing the threshold about 20 minutes later. They were greeted by fellow American astronaut Chris Cassidy, as well as Russia cosmonauts Anatoli Ivanishin and Ivan Vagner.
The five men posed for photos and then NASA administrator Jim Bridenstine spoke to the crew from mission control in Houston. “Welcome to Bob and Doug,” said Bridenstine. “I will tell you the whole world saw this mission, and we are so, so proud of everything you have done for our country.”
“It’s great to get the United States back in the crewed launch business and we’re just really glad to be on board this magnificent complex,” replied Hurley.
Russian space chief Dmitry Rogozin also congratulated both NASA and Elon Musk, the founder of the private aerospace company SpaceX that built the Crew Dragon capsule.
The capsule spent 19 hours chasing down the station at speeds of up to 17,500 miles per hour before carefully aligning to its target and slowing to a crawl for the delicate docking procedure, which took place over northern China.
During their stay Behnken and Hurley will perform more checks on the capsule to certify its readiness as the United States transitions to using the commercial sector for rides to the ISS.
The space agency has had to rely on Russian Soyuz rockets ever since the Space Shuttle program ended in 2011 — with 2015 the original target for a replacement program.
The United States has paid SpaceX and aerospace giant Boeing a total of about $7 billion for their “space taxi” contracts. Boeing’s program had a failed test run late last year, which left SpaceX as clear frontrunner.
Hurley said he hoped the mission would inspire young Americans. “This was just one effort that we can show for the ages in this dark time that we’ve had over the past several months to kind of inspire, especially the young people in the United States, to reach for these lofty goals,” he said.
SpaceX’s two-stage Falcon 9 rocket began its voyage on Saturday, blasting off flawlessly in a cloud of bright orange flames and smoke from Florida’s Kennedy Space Center.
“I’m really quite overcome with emotion,” Musk said. “It’s been 18 years working towards this goal.” Hurley and Behnken had named their capsule “Endeavour” after the retired Space Shuttle on which they both flew.
NASA still plans to use Soyuz rockets to send some astronauts into space with each seat costing around $80 million.
