The James Webb Space Telescope extended a four-foot tower Wednesday to give the observatory’s mirrors and instruments, designed to function at cryogenic temperatures, enough separation from the hot side of the spacecraft after the mission’s sunshield deploys over the next few days.

Mission controllers started the risky process Tuesday to unfurl the James Webb Space Telescope’s sunshield, a five-layer thermal barrier necessary to give the observatory infrared vision into the distant universe.

An Ariane 5 rocket, propelled by a main engine and two solid-fueled boosters, leaps off the pad at the Guiana Space Center with the James Webb Space Telescope.
The James Webb Space Telescope, a NASA-led international collaboration that took nearly 30 years and $10 billion to get to the launch pad, finally left Earth with a Christmas morning rocket ride from a European spaceport in South America, setting off on a mission to hunt for the first light in the universe. That was just the easy part.

Teams in French Guiana positioned a European Ariane 5 rocket into its starting blocks Thursday, ready for liftoff Christmas morning with the nearly $10 billion James Webb Space Telescope, the most expensive science instrument ever to leave planet Earth.
Spaceflight Now’s Editor, Stephen Clark, speaks with NASA’s Keith Parrish, the commissioning manager for the Webb Space Telescope. It is his job to make sure the observatory unfolds and extends correctly. He talks us through the deployment sequence in the month after launch. Find out how shake, shimmy and twirl are in the ground controller’s tool box to fix anything that goes wrong.
Spaceflight Now’s Stephen Clark speaks to astronaut, astronomer and former NASA science head, John Grunsfeld about the upcoming launch of the James Webb Space Telescope. What big discoveries is he expecting from JWST? Is he nervous about the complex process to unfold the telescope in space? Why did his efforts to prepare JWST for possible servicing fail?

Beginning next year, the James Webb Space Telescope will scan a sampling of the nearly 5,000 alien worlds discovered around other stars to help astronomers identify which of the rocky planets might have atmospheres that could sustain life.
