NASA’s James Webb Space Telescope, a revolutionary instrument built to peer the farthest yet into the cosmos, was launched by rocket early on Saturday from South America’s northeastern coast.
It is the world’s largest and most powerful space telescope ever built.
A joint effort with ESA (European Space Agency) and the Canadian Space Agency, the Webb observatory is NASA’s revolutionary flagship mission to seek the light from the first galaxies in the early universe and to explore our own solar system, as well as planets orbiting other stars, called exoplanets.
The powerful $9 billion infrared telescope, hailed by NASA as the premiere space-science observatory of the next decade, was carried aloft inside the cargo bay of an Ariane 5 rocket that blasted off at about 7:30am EST from the European Space Agency’s (ESA) launch base in French Guiana.
If all goes as planned, the 14,000-pound instrument will be released from the French-built rocket after a 26-minute ride into space and gradually unfurl to nearly the size of a tennis court over the next 13 days as it sails onward.
“The James Webb Space Telescope represents the ambition that NASA and our partners maintain to propel us forward into the future,” said NASA Administrator Bill Nelson. “The promise of Webb is not what we know we will discover; it’s what we don’t yet understand or can’t yet fathom about our universe. I can’t wait to see what it uncovers!”
