CAPE CANAVERAL, Fla. — A European space telescope blasted off Saturday on a quest to explore the mysterious and invisible realm known as the dark universe.
SpaceX launched the European Space Agency’s Euclid observatory toward its ultimate destination 1 million miles away, the Webb Space Telescope’s neighborhood. It will take a month to get there and another two months before it starts its ambitious six-year survey this fall.
Flight controllers in Germany declared success nearly an hour into the flight, applauding and shouting “Yes!” as the telescope phoned home after a smooth liftoff.
“I’m so thrilled, I’m so excited to see now this mission up in space, knowing it is on its way,” the European Space Agency’s director general, Josef Aschbacher, said from the Florida launch site.
Named for antiquity’s Greek mathematician, Euclid will scour billions of galaxies covering more than one-third of the sky. By pinpointing the location and shape of galaxies up to 10 billion light-years away — almost all the way back to the cosmos-creating Big Bang — scientists hope to glean insight into the dark energy and dark matter that make up most of the universe and keep it expanding.
Scientists understand only 5 percent of the universe: stars, planets, us. The rest is “still a mystery and an enigma, a huge frontier in modern physics that we hope this mission will actually help to push forward,” the European Space Agency’s science director, Carole Mundell, said just before liftoff.
The telescope’s highly anticipated 3D map of the cosmos will span both space and time in a bid to explain how the dark universe evolved and why its expansion is speeding up.
The lead scientist for the $1.5 billion mission said Euclid will measure dark energy and dark matter with unprecedented precision.
Fifteen feet tall and almost as wide, Euclid sports a 4-foot telescope and two scientific instruments capable of observing the cosmos in both visible light and the near infrared. A huge sunshield is designed to keep the sensitive systems at the properly frigid temperatures.
