WASHINGTON: Nasa gave the green light on Friday to next week’s launch of two astronauts aboard a SpaceX vessel – the first crewed space flight from US soil in nine years and a crucial step towards ending American dependence on Russian rockets.
Top officials at the US space agency and Elon Musk’s company had been meeting since Thursday at the Kennedy Space Center in Florida for final checks of the Crew Dragon space capsule ahead of its maiden May 27 crewed mission.
“At the end we got to a go,” Nasa administrator Jim Bridenstine told reporters by video of the meticulous Flight Readiness Review, which provided the go-ahead.
US astronauts Robert Behnken and Douglas Hurley are scheduled to blast off from Kennedy’s historic Launch Pad 39A at 4.33pm (2033 GMT) on Wednesday for the International Space Station, arriving the next day.
Asked about going ahead with the mission in the midst of the coronavirus pandemic, Behnken told reporters: “Where there’s a will, there’s a way.”
Behnken and Hurley have been in strict quarantine since May 13 because of the pandemic, but they said their actual isolation began as far back as mid-March.
American astronauts have been flying to the ISS, which currently houses two Russians and one American, on Russian rockets since the US space shuttle program was shelved in 2011 after three decades of service.
Should the SpaceX mission succeed, the US will have achieved its goal of no longer having to buy seats on Russian Soyuz rockets to send astronauts to the ISS, which has been occupied by US and Russian astronauts since 2000.
Unlike the space shuttle – which suffered two fatal accidents – the SpaceX capsule includes an emergency escape system in the event there is a problem after liftoff.
At the end of the mission, which is expected to last several months, Crew Dragon will splash down in the ocean like the Apollo capsules did, slowed down by four enormous parachutes.
SpaceX and Boeing are being called upon to carry out six crewed voyages each to the ISS over the next few years.
If next week’s Crew Dragon mission – baptised Demo-2 – is successful SpaceX will be the first private company ever to deliver astronauts to the ISS. — AFP
