SpaceX成功发射重型猎鹰火箭 部署24颗卫星

American space company SpaceX has successfully launched its large Falcon Heavy rocket on a flight to deploy 24 satellites.

美国太空探索技术公司SpaceX成功发射大型猎鹰重型火箭,此次发射将部署24颗卫星。

The rocket lifted off early Tuesday morning from Florida’s Kennedy Space Center. The Falcon Heavy is considered the world’s most powerful operating rocket.

这枚火箭周二清晨从佛罗里达州肯尼迪航天中心发射升空。猎鹰重型火箭被认为是世界上最强大的运行火箭。

It was the third successful flight of a Falcon Heavy rocket. The U.S. Department of Defense ordered the current mission.

这是猎鹰重型火箭第三次成功发射。美国国防部下令执行这一任务。

The satellites will be used for experiments involving several U.S. government agencies, as well as some university projects.

这些卫星将被用于几个美国政府机构以及一些大学项目的实验研究。

SpaceX chief Elon Musk said Tuesday’s mission was the company’s “toughest rocket launch ever.” It required four separate upper-stage engine firings. The satellites also needed to be placed in three different orbits. The process was expected to take about six hours.

SpaceX首席执行官埃隆·马斯克表示,周二的任务是该公司“有史以来最艰难的火箭发射任务”。此次发射需要四次独立的上层发动机点火。这些卫星还需要被部署到三个不同的轨道上。整个过程预计需要大约6个小时。

SpaceX uses reusable rockets to reduce the cost of space travel for its customers. These include government and military agencies, the U.S. space agency NASA and private companies.

SpaceX使用了可循环使用的火箭来降低客户太空旅行的成本。其中包括政府和军事机构、美国宇航局和私营公司。

Several minutes after liftoff, the Falcon Heavy’s two side boosters returned safely to Earth and landed at Florida’s Cape Canaveral Air Force Station. The center booster was supposed to land on a special platform in the Atlantic Ocean, but did not reach its target.

发射升空几分钟后,“猎鹰重型”的两侧助推器安全返回地球,并降落在佛罗里达州卡纳维拉尔角空军基地。中央核心助推器本应降落在大西洋的一个特殊平台上,但没有到达指定着陆点。

SpaceX said the landing failure of the center booster was not unexpected because of the difficult nature of the mission. “It was a long shot,” SpaceX’s Musk said on Twitter.

SpaceX表示,由于任务的难度较大,因此中央核心助推器的着陆失败并不意外。SpaceX的马斯克在推特上说:“这是一次不大有希望会成功的尝试。”

In addition to the satellites, the Falcon Heavy carried an atomic clock built by NASA, a solar sail project and even human ashes.

除了卫星,猎鹰重型火箭还搭载着一个由美国宇航局制造的原子钟、一艘太阳帆,甚至还有人类骨灰。

The Deep Space Atomic Clock is a technology experiment aimed at giving spacecraft self-flying abilities in the future.

深空原子钟是一项技术实验,旨在赋予未来航天器自主飞行的能力。

The solar sail project was led by the U.S.-based Planetary Society. The goal of the group’s LightSail is to become the first orbiting spacecraft to be powered completely by sunlight. The head of the Planetary Society is scientist and television star Bill Nye, who praised SpaceX for its cooperation. “Hey @elonmusk, thanks for the ride!” he tweeted.

太阳帆是美国行星协会发起的项目。该协会“光帆号”的目标是成为第一个完全由阳光驱动的轨道航天器。行星协会主席是科学家兼电视明星比尔·奈伊,他赞扬了与SpaceX的合作。“嘿@elonmusk,谢谢你的搭载!”他在推特中写道。

Among the human ashes on the flight were some belonging to astronaut Bill Pogue, who flew on NASA’s first space station, Skylab, in the 1970s. Pogue died in 2014.

这次飞行搭载的人类骨灰中有已逝宇航员比尔·波格的骨灰,上个世纪90年代,他曾在美国宇航局的第一个空间站“天空实验室”上飞行。波格于2014年去世。

The Falcon Heavy is the most powerful rocket in use today. Each first-stage booster has nine engines, for a total of 27 firing at the same time during liftoff. SpaceX says the rocket has the ability to lift nearly 64 metric tons into orbit. Only NASA’s Saturn V rocket, which took U.S. astronauts to the moon, had the ability to carry more into space.

猎鹰重型火箭是目前使用的最强大的火箭。每个一级助推器有9个发动机,发射时同时点火27次。SpaceX公司表示,该火箭可承载近64公吨的物品进入轨道。只有美国宇航局建造的土星5号火箭能承载更重的物品进入太空,该火箭曾搭载美国宇航员登上月球。
