“Today we said goodbye to the telescope on the ground, and we opened our eyes to the universe.” “When we look farther, delve deeper or measure more precisely, we’re bound to find something wondrous,” says Ken Sembach, the Space Telescope Science Institute’s director. The James Webb Space Telescope is very much a part of that exploration.”Īs JWST separated from its rocket’s upper stage, a video feed showed the now independent spacecraft gleaming in sunlight, capturing one last close-up look at the observatory before its quest to pierce the veil of cosmic darkness took it inaccessibly far from Earth. That’s what this business is all about, and that’s why we dare to explore. “We know that in great reward, there is great risk. going to take us back to the very beginnings of the universe,” said NASA administrator Bill Nelson in postlaunch remarks. “This is a great day-not only for America and our European and Canadian partners, but it’s a great day for Planet Earth. As the successor to the Hubble Space Telescope (HST), JWST is one of those once-in-a-generation scientific projects that can strain the patience of government benefactors, as well as the responsible agency’s credibility, but also define a field for decades to come-and possibly redefine it forever. Also at risk is the viability of NASA’s vast space-science portfolio, if not the future of astronomy itself. Only after that first deployment proved successful, said a NASA spokesperson in a statement to Scientific American, would “we know we have a mission.”Īstronomers have more riding on the rocket than the James Webb Space Telescope (JWST). Half an hour postlaunch, the telescope still needed to decouple from its host rocket, after which it had to deploy solar panels to partly power its journey. (ET), the rocket carrying the largest, most ambitious space telescope in history cleared the launchpad in French Guiana, and the members of mission control at the Space Telescope Science Institute in Baltimore roared their elation. The relief was as deep as the stakes were high.
