NASA’s massive James Webb telescope is folded down to launch size for first time

Folding the James Webb Space Telescope to Fit Inside the Ariane V Rocket Fairing

NASA’S James Webb Space Telescope has achieved a milestone in preparations for its upcoming launch, despite work on the project being limited due to the coronavirus pandemic. The entire telescope has been folded down and stowed into the configuration that will be used for its launch, currently scheduled for next year.

The telescope includes a massive origami mirror which folds out to be 6.5 meters (over 21 feet) across, but has to fold down small enough to fit inside a rocket payload fairing so it can be launched into orbit. It also has a tennis court-sized sunshield that needs to be folded and stowed to fit in the limited space in the fairing.

With such large and delicate components needing to be stowed, getting them to fold down correctly is a big step in preparing the telescope for its eventual launch.

“The James Webb Space Telescope achieved another significant milestone with the entire observatory in its launch configuration for the first time, in preparation for environmental testing,” Bill Ochs, Webb project manager for NASA Goddard Space Flight Center, said in a statement.

“I am very proud of the entire Northrop Grumman and NASA integration and test team. This accomplishment demonstrates the outstanding dedication and diligence of the team in such trying times due to COVID-19.”

With the global pandemic of the coronavirus, NASA employees are working from home and many projects have had to be suspended, including the announcement that integration and testing operations on the James Webb would be suspended. But NASA says that progress is still being made on the telescope, albeit with a reduced team.

“While operating under augmented personal safety measures because of the novel coronavirus (COVID-19), the project continues to make good progress and achieve significant milestones in preparation for upcoming environmental testing,” Gregory L. Robinson, the Webb program director at NASA Headquarters said in the statement.

“Team member safety continues to be our highest priority as the project takes precautions to protect Webb’s hardware and continue with integration and testing. NASA will continually assess the project’s schedule and adjust decisions as the situation evolves.”

Meet NASA’s trio of mini moon rovers set to launch next year
Part of NASA’s CADRE technology demonstration, three small rovers that will explore the Moon together show off their ability to drive as a team autonomously – without explicit commands from engineers – during a test in a clean room at the agency’s Jet Propulsion Laboratory in December 2023.

NASA is ramping up its plans for exploring the moon, not only in terms of preparing to send astronauts there but also rovers. There's the VIPER rover, which will search for water around the lunar south pole, and now NASA is introducing a trio of mini rovers called CADRE, or Cooperative Autonomous Distributed Robotic Exploration. These will work together as a team to map the lunar surface, testing the possibilities of using rovers in groups for future exploration.

The rovers, developed at NASA's Jet Propulsion Laboratory, are just the size of a carry-on suitcase. They are designed to move independently but share data so they can cover more ground than a single rover could. They'll have to work over a lunar day, which is about two weeks, to map out features on the surface and look below ground using radar.
