CAPE CANAVERAL, Fla. (AP) — The $10 billion successor to the Hubble Space Telescope is about to take flight. NASA is entrusting the launch of the world’s biggest and most powerful space observatory to its European partners.

A French-built rocket is poised to blast off from South America on Friday with the James Webb Space Telescope.

Years behind schedule, the elaborate, budget-busting telescope had to be folded origami-style to fit in the rocket.

That’s because its sunshield is the size of a tennis court. Webb is designed to peer almost all the way back in time, beholding the first stars.
