In another major milestone for the James Webb Space Telescope, a motor-driven tripod unfolded as planned Wednesday, moving a 2.4-foot-wide secondary mirror into position to reflect collected starlight back down to the instruments that will study it.

The final layers of the James Webb Space Telescope’s sunshade were robotically pulled taut with a system of motors, cables, and pulleys Tuesday, clearing a major milestone before unfolding mirrors to collect light from the oldest galaxies in the universe.

Mission controllers started the delicate work of tightening the five razor-thin layers of the James Webb Space Telescope’s sunshade Monday. Managers said the nearly $10 billion observatory is “hunky-dory” after pausing deployments over the weekend to adjust the observatory’s power levels and ensure motors needed for the tensioning are in tip-top shape.

Flying outbound from Earth at a distance of more than 400,000 miles, the James Webb Space Telescope extended one of two booms Friday to begin unfurling the mission’s five-layer sunshield. With the port-side boom deployed, work is underway tonight to extend another boom on the starboard side.

A Russian Soyuz rocket launched Monday with 36 more OneWeb internet satellites, the 12th of 19 Soyuz missions needed to deliver into orbit the company’s first-generation network of nearly 650 spacecraft.

The James Webb Space Telescope opened covers that protected the mission’s folded sunshield Thursday, and deployed a momentum flap to help the observatory balance against the unending light pressure from the sun.

China launched two classified Shiyan satellites Dec. 23 into a geostationary transfer orbit aboard a Long March 7A rocket, one of the country’s newest launch vehicles. The mission took off from China’s Wenchang launch base on Hainan Island.

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.
