SpaceX成功发射新一批宇航员,接替NASA被困人员

SpaceX于周五晚成功发射新一批宇航员前往国际空间站,接替因飞船故障而滞留了九个月的NASA宇航员Butch Wilmore和Suni Williams。新团队包括NASA的Anne McClain和Nichole Ayers(均为军用飞行员),以及日本的Takuya Onishi和俄罗斯的Kirill Peskov(均为前航空公司飞行员),预计将在周六晚抵达空间站,并在未来六个月内执行常规任务。

The replacements for NASA’s two stuck astronauts launched to the International Space Station on Friday night, paving the way for the pair’s return after nine long months.

Butch Wilmore and Suni Williams need SpaceX to get this relief team to the space station before they can check out. Arrival is set for late Saturday night.

NASA wants overlap between the two crews so Wilmore and Williams can fill in the newcomers on happenings aboard the orbiting lab. That would put them on course for an undocking next week and a splashdown off the Florida coast, weather permitting.

The duo will be escorted back by astronauts who flew up on a rescue mission on SpaceX last September alongside two empty seats reserved for Wilmore and Williams on the return leg.

Rocketing toward orbit from NASA’s Kennedy Space Center, the newest crew includes NASA’s Anne McClain and Nichole Ayers, both military pilots; and Japan’s Takuya Onishi and Russia’s Kirill Peskov, both former airline pilots. They will spend the next six months at the space station, considered the normal stint, after springing Wilmore and Williams free.

As test pilots for Boeing’s new Starliner capsule, Wilmore and Williams expected to be gone just a week or so when they launched from Cape Canaveral on June 5. A series of helium leaks and thruster failures marred their trip to the space station, setting off months of investigation by NASA and Boeing on how best to proceed.

Eventually ruling it unsafe, NASA ordered Starliner to fly back empty last September and moved Wilmore and Williams to a SpaceX flight due back in February. Their return was further delayed when SpaceX’s brand new capsule needed extensive battery repairs before launching their replacements. To save a few weeks, SpaceX switched to a used capsule, moving up Wilmore and Williams’ homecoming to mid-March.

Already capturing the world’s attention, their unexpectedly long mission took a political twist when President Donald Trump and SpaceX’s Elon Musk vowed earlier this year to accelerate the astronauts’ return and blamed the former administration for stalling it.

Retired Navy captains who have lived at the space station before, Wilmore and Williams have repeatedly stressed that they support the decisions made by their NASA bosses since last summer. The two helped keep the station running — fixing a broken toilet, watering plants and conducting experiments — and even went out on a spacewalk together. With nine spacewalks, Williams set a new record for women: the most time spent spacewalking over a career.

A last-minute hydraulics issue delayed Wednesday’s initial launch attempt. Concern arose over one of the two clamp arms on the Falcon rocket’s support structure that needs to tilt away right before liftoff. SpaceX later flushed out the arm’s hydraulics system, removing trapped air.

The duo’s extended stay has been hardest, they said, on their families — Wilmore’s wife and two daughters, and Williams’ husband and mother. Besides reuniting with them, Wilmore, a church elder, is looking forward to getting back to face-to-face ministering and Williams can’t wait to walk her two Labrador retrievers.
