SpaceX rocket returns to shore after historic astronaut launch (photos)
4.完整新聞內文:
The rocket that launched SpaceX's first-ever crewed mission has returned to
terra firma.
That mission, called Demo-2, lifted off atop a two-stage Falcon 9 rocket on
Saturday (May 30) from NASA's Kennedy Space Center in Florida, sending NASA
astronauts Bob Behnken and Doug Hurley toward the International Space Station
(ISS) aboard a Crew Dragon capsule.
About 9 minutes after liftoff, the Falcon 9 first stage aced a pinpoint
landing on the SpaceX drone ship "Of Course I Still Love You," which was
stationed a few hundred miles off the Florida coast. The ship soon started
heading back toward shore, and on Tuesday (June 2) its sea voyage came to an
end: "Of Course I Still Love You," with the rocket secured to its deck,
arrived at Florida's Port Canaveral, SpaceX announced via Twitter.
SpaceX commonly refurbishes and reflies Falcon 9 first stages, as well as the
first stages of the company's Falcon Heavy megarocket. Such reuse is a key
priority of SpaceX founder and CEO Elon Musk, who wants to cut the cost of
spaceflight dramatically enough to enable a variety of ambitious exploration
feats — especially the colonization of Mars. (The one-engine Falcon 9 second
stage remains expendable at the moment, but it's not nearly as expensive as
the nine-engine first stage.)
We perhaps cannot assume that this particular booster will fly again,
however. SpaceX had not announced its fate as of the time of this writing,
and it's possible the company might want to preserve it as a historic
artifact. The first Falcon 9 first stage that ever landed successfully, for
example, now stands outside SpaceX's headquarters in Hawthorne, California.
And this particular Falcon 9 has a little bit of added historic appeal beyond
Saturday's exploits: Emblazoned across its body is NASA's retro "worm" logo,
which was brought out of retirement for Demo-2.
Demo-2, the first orbital human spaceflight to launch from the United States
since NASA's space shuttle fleet retired in 2011, is a joint SpaceX-NASA
effort. The company holds a $2.6 billion contract with NASA's Commercial Crew
Program to fly six operational crewed missions to the ISS, and Demo-2 is
designed to fully validate Crew Dragon and the Falcon 9 for those flights.
The Crew Dragon carrying Behnken and Hurley, named Endeavour after one of
NASA's old space shuttle orbiters, arrived at the ISS on Sunday (May 31).
Behnken and Hurley will stay aboard the orbiting lab for one to four months;
Demo-2's duration has not yet been decided.

無人回收艦它本身具有四具螺旋槳，可以在回收火箭時保持自己的位置
至於出港口跟回程通常是用另一艘船拖回來
它本身的動力不是設計用來長程移動的

Falcon 9 用的燃料是液氧跟煤油，火箭裡面都會有殘留不會用完
如果倒掉燃料槽或管線破損，加上一點小火花就會爆炸
