Watch: Nasa launches Roman telescope from Kennedy Space Center Nasa's powerful next-generation telescope has blasted off into space from its launchpad in Florida, with a mission to explore dark energy, black holes and other mysteries of the Universe.
观看：美国宇航局从肯尼迪航天中心发射罗马望远镜 美国宇航局强大的下一代望远镜已从佛罗里达州的发射台发射升空，其任务是探索暗能量、黑洞和宇宙的其他奥秘。
The Nancy Grace Roman telescope will capture vast panoramic views of space, with a field of vision 100 times larger than both the Hubble and James Webb space telescopes, Nasa says.
美国宇航局表示，南希·格蕾丝·罗曼望远镜将捕捉广阔的太空全景，其视野比哈勃和詹姆斯·韦伯太空望远镜大100倍。
The mission begins with a 100-day journey to a vantage point roughly one million miles from Earth, where the telescope will then start charting planets outside our solar system, known as exoplanets.
该任务从为期 100 天的旅程开始，到达距地球约 100 万英里的有利位置，然后望远镜将开始绘制太阳系外行星（称为系外行星）的图表。
"Roman is going to change the way we look at the Universe," said Nicky Fox, a Nasa administrator.
“罗曼将改变我们看待宇宙的方式，”美国宇航局管理员尼基福克斯说。
The successful launch of the telescope took place on Sunday morning local time from the Kennedy Space Center in Florida.
该望远镜于当地时间周日上午在佛罗里达州肯尼迪航天中心成功发射。
Jackie Townsend, a project manager on Nasa's Roman telescope, described it as "glorious" at a news conference afterwards.
美国宇航局罗马望远镜的项目经理杰基·汤森德在随后的新闻发布会上形容这是“光荣的”。
"The ride was magnificent. It put us right where we wanted to be." About 30 minutes after launch, Roman separated from its SpaceX rocket and is now heading towards its orbiting point around a million miles away.
“这次旅程非常棒。 它让我们到达了我们想去的地方。” 发射后约 30 分钟，Roman 与 SpaceX 火箭分离，目前正朝着约 100 万英里外的轨道点前进。
A SpaceX Falcon Heavy rocket lifts off carrying Nasa's Nancy Grace Roman Space Telescope Fox said Roman "is going to discover tens of thousands, maybe even 100,000 new exoplanets" - referring to planets located outside of our solar system.
SpaceX 猎鹰重型火箭搭载 NASA 的南希·格雷斯·罗马太空望远镜升空 福克斯表示，罗曼“将发现数万颗，甚至可能是 10 万颗新的系外行星”——指的是位于太阳系之外的行星。
"Why do we care so much about exoplanets?
“为什么我们如此关心系外行星？
Because one of our main goals at Nasa is answering the question, 'Are we alone in the universe'?" she added.
因为我们在美国宇航局的主要目标之一就是回答这个问题，‘我们在宇宙中是孤独的吗’？”她补充道。
US President Donald Trump dialled in to the space agency's news conference to congratulate the scientists working on the project. "You're the hottest in space, and we have the hottest country anywhere in the world.
美国总统唐纳德·特朗普拨通了航天局的新闻发布会，向从事该项目的科学家表示祝贺。 “你们是太空中最热门的，而我们拥有世界上最热门的国家。
So, let's keep it all going.
所以，让我们继续一切。
You're a big part of it," Trump said. The telescope was on display at the Goddard Space Center in April Astronomer Jenifer Millard said the telescope will be four times further from Earth than the Moon is, where a lot of infrared space cameras - made to pick up what she describes as "heat light"- operate. She told the BBC this is to make sure infrared light from the Moon and Earth don't interfere with the cameras.
你是其中的重要组成部分，”特朗普说。 该望远镜于四月在戈达德航天中心展出 天文学家詹妮弗·米勒德表示，这架望远镜距离地球的距离将是月球距离的四倍，月球上有许多红外太空相机，用于捕捉她所说的“热光”。 她告诉英国广播公司，这是为了确保来自月球和地球的红外光不会干扰相机。
Nasa's James Webb Space Telescope, launched in 2021, also orbits the Sun around one million miles from Earth, but its field of vision is not as expansive.
美国宇航局 (NASA) 的詹姆斯·韦伯太空望远镜于 2021 年发射，也绕太阳运行，距地球约 100 万英里，但其视野没有那么广阔。
Nasa's Hubble Space Telescope, launched in 1990, orbits at about 300 miles above Earth's surface.
美国宇航局的哈勃太空望远镜于 1990 年发射，其轨道距地球表面约 300 英里。
While Roman will look outward into the Universe, Millard said scientists are also anticipating it will find thousands of new worlds in our own galaxy.
米勒德表示，虽然罗曼将向外观察宇宙，但科学家们也预计它将在我们自己的星系中发现数千个新世界。
Nancy Grace Roman (1925-2018) was known as the "mother of Hubble" for her tole in planning the Hubble telescope The telescope is named after physicist Nancy Grace Roman, who was Nasa's first chief astronomer in the 1960s and its first female executive. During her career, she was instrumental in getting the Hubble Space Telescope approved by US Congress and later said its most interesting discovery was dark energy.
南希·格雷斯·罗曼（Nancy Grace Roman，1925-2018）因其在规划哈勃望远镜方面的贡献而被称为“哈勃之母” 该望远镜以物理学家南希·格雷斯·罗曼 (Nancy Grace Roman) 的名字命名，她是 20 世纪 60 年代美国宇航局第一位首席天文学家，也是第一位女性高管。 在她的职业生涯中，她在哈勃太空望远镜获得美国国会批准方面发挥了重要作用，后来表示其最有趣的发现是暗能量。
The new telescope is similarly expected to revolutionise our understanding of the Universe, including through investigating dark energy.
同样，新望远镜也有望彻底改变我们对宇宙的理解，包括通过研究暗能量。
It has a five-year primary lifespan with a goal to operate for 10 years.
它的主要寿命为五年，目标是运行 10 年。
Nasa says its "crisp, sweeping surveys will help scientists investigate dark energy and dark matter, discover and characterise exoplanets, map billions of galaxies, study black holes, and explore objects from our own solar system to the edge of the observable Universe."
美国宇航局表示，其“清晰、全面的调查将帮助科学家研究暗能量和暗物质，发现和描述系外行星，绘制数十亿个星系的地图，研究黑洞，并探索从太阳系到可观测宇宙边缘的物体。”
Dark matter, which is invisible, acts as a kind of gravitational glue, while dark energy is believed to be a repulsive force driving the Universe's expansion.
暗物质是不可见的，充当一种引力胶，而暗能量被认为是驱动宇宙膨胀的排斥力。
Together, they are thought to make up about 95% of the Universe. "One of our main goals at Nasa is answering the question: are we alone in the Universe?"
据认为，它们共同构成了宇宙的 95% 左右。 “美国宇航局的主要目标之一是回答这个问题：我们在宇宙中是孤独的吗？”
Fox said at a Sunday morning news conference.
福克斯在周日上午的新闻发布会上说道。
"With Roman, we are going to make this giant leap forward... that is going to allow us to look at these distant, distant worlds and start to really resolve the atmosphere around them to let us know: could they be habitable?" Millard said, through the work of telescopes like Roman, scientists are hoping to create "enormous cosmic maps" of the Universe at various stages.
“有了罗马，我们将实现巨大的飞跃……这将使我们能够观察这些遥远的世界，并开始真正解析它们周围的大气层，让我们知道：它们是否适合居住？” 米勒德说，通过像罗曼这样的望远镜的工作，科学家们希望能够绘制出宇宙各个阶段的“巨大的宇宙地图”。
"They'll be almost like an onion, so you can peel back layer upon layer... and see how the distribution of galaxies changes through cosmic time," she said. "What we want to do is use this distribution to try and figure out dark matter and dark energy because we know they exist, we see their effects, but what they are is a real mystery."
“它们几乎就像洋葱一样，所以你可以一层一层地剥开......并观察星系的分布如何随着宇宙时间而变化，”她说。 “我们想做的是利用这种分布来尝试找出暗物质和暗能量，因为我们知道它们存在，我们看到它们的影响，但它们到底是什么是一个真正的谜。”
