James Webb Space Telescope will use high-tech origami technology to “drill” into rocket

What should be done when the cutting-edge space telescope is too big for any rocket at this stage, according tomedia reports. NASA’s James Webb Space Telescope is facing such a problem that the agency has come up with a way to use origami technology. That is, the space telescope is folded into the Ariane 5 rocket like a butterfly and put into orbit as planned.

The James Webb telescope, the largest and most complex space telescope ever developed by man, can measure more than 66 feet by 46 feet when its giant hood is opened. NASA completed the assembly in August 2019 and has been testing mirrors and scientific instruments ever since.

Weber is actually made up of two main parts: the telescope itself, a conical device that can point to distant galaxies; its optical telescope element consists of 18 52-inch hexagonal lenses, each made of molybdenum and goldplated. Together, they form a 21-foot-diameter mirror, which is much larger than the Hubble Space Telescope.

However, to make it look at the infrared spectrum correctly, it needs to stay cool. That’s what the second part does, and the huge sun visor will help it stay at minus 370 degrees Fahrenheit. Each layer of the five-layer structure of the sun visor is as thin as a human hair and is made of polyamide film and aluminum-silicon coating.

The telescope’s sun visor needs to be folded a total of 12 times if it wants to squeeze into the Ariane 5 rocket. This will reduce the Weber telescope to the size of a load rectifier suitable for 15 feet by 53 feet, like a moth in a moth.

Next, if the telescope folds successfully, engineers at NASA, ESA and the Canadian Space Agency will conduct final acoustic and vibration tests. If all this succeeds, it will be sent to French Guiana in ten months’ time for its final pre-launch deployment.
