SA のユークリッド宇宙船は、4 月 30 日にフロリダ州ポートカナベラルに到着した後、ケープカナベラル近くのアストロテック施設に移されました。 この衛星は、7 月までに SpaceX の Falcon 9 ロケットで打ち上げられる予定で、太陽と地球のラグランジュ ポイント L2 まで 150 万 km 移動します。 Euclid は、天空の 3 分の 1 以上にわたる数十億の銀河をマッピングし、天文学者が宇宙の膨張、銀河の大規模な分布、重力、暗黒物質、暗黒エネルギーの役割を研究するのに役立ちます。大宇宙。 クレジット: Thales Alenia Space / ImagIn

ESA の Euclid 宇宙船は、[{” attribute=””>SpaceX Falcon 9 rocket in July, mapping billions of galaxies to study the Universe’s expansion, gravity, dark matter, and dark energy.

ESA’s Euclid spacecraft finished its ocean cruise safe and sound on April 30 at Port Canaveral in Florida. Subsequently, the satellite was moved by road to the Astrotech facility near Cape Canaveral.

Euclid will launch on a SpaceX Falcon 9 rocket, no earlier than July, before starting its 1.5 million km journey to the Sun-Earth Lagrange point L2. In orbit, Euclid will map billions of galaxies out to 10 billion light years, across more than one-third of the sky.

Euclid’s cosmic map will help us understand the Universe’s mysterious components: dark matter and dark energy. Together they appear to make up 95% of the Universe, while the normal matter that we know and are made of (together with stars, planets and all we see) makes up the other 5%.

Astronomers will use Euclid observations to study the evolution of the expansion of the Universe and the large-scale distribution of galaxies over cosmic history. From this, we can learn more about the role of gravity and the nature of dark matter and dark energy.
