"I don't expect any drama." "Sun Shield.

On Monday, six engines on the telescope began to fully expand the first of five sunscreens. These tennis-size layers, each made of a polyamide layer called kapton, shade the machine and allow it to cool to 50 K, which is -223 degrees Celsius and just 50 degrees above absolute zero. This wonderful environment is very important for the web to see infrared light and to detect heat from very distant objects. . The goal is to expand the other four layers on Tuesdays and Wednesdays. After this time, the massive coverage of the sun will be complete - the most intricate aspect of the complex diffusion process. "I don't expect any drama," Ochs said at a news conference on Monday over the next few days. There by the way. All told, from launch to launch, the web instrument must perform 344 actions in which a single point failure could destroy the telescope. After installing the sunvisor, Ochs said the Webb tool will overcome "70 to 75%" of single-point failures. Advertising

Support for secondary mirrors. And open the second wing of the main web mirror. These activities can be completed by the end of this week and the deployment phase can be practically completed.

Although scientific operations won't begin until mid-2022, NASA engineers and thousands of scientists will breathe a sigh of relief. . It took 20 years of hard work to get the web into space, and in less than 20 days, the telescope will be fully deployed - or not.

As part of the deployment, teams of NASA engineers, scientists and the telescope's main contractor, Northrop Grumman, have worked in 12-hour shifts since the launch of the Ariane 5 rocket this Christmas. "Over the weekend, the teams worked on two relatively small problems. There are five layers in the <b>James</b> <b>Webb</b> <b>Space</b> Telescope's solar mantle. There are five layers of the heliosphere for the James Webb Space Telescope. The first problem was NASA

is the performance of the 6-meter-high solar telescope array. Although the observatory has never had a "blackout," Lu said the initial five-panel configuration wasn't optimal. To achieve full power, he said , the matrix has been rebalanced and is now working as intended. This is not expected to be an issue in the future.

Another potential problem is the six engines involved in the traction. Lu said they were "running a little hot" , but after repositioning the telescope to keep them cooler, they reached 327 K, well below the operating limit of 340 K. Lu said he expects the engines to remain below the maximum for the next three days.
