NASA's next big space observatory—the James Webb Space Telescope—just had its mirror assembly completed. It's 18-segment gold-plated mirror, that is.

The National Institute of Standards and Technology (NIST) has accurately measured parts designed for the upcoming James Webb Space Telescope, the long-awaited successor to the Hubble Space Telescope. The NIST-measured composite titanium and stainless steel parts, which support the skeleton for the telescope’s massive mirror, will be used in the final round of NASA’s vibration tests on the mirror assembly before the telescope’s scheduled launch in October 2018.

The science we’re bound to learn from JWST is unlike anything else we’ve ever learned, and that’s why it was selected as the flagship NASA mission of this decade: the 2010s.
It will be the largest, most sophisticated (and most expensive) piece of scientific equipment ever launched into space. Here's why it matters.

This may not be everyone's cup of tea, but it's a conversation by modern Friends of Epicurus on the ancient Epicurean conception of the Gods rooted in atomism, which evolved into speculation on the possibility of superior beings from other worlds. It includes the several different viewpoints that exist within the School, from the speculators to those skeptical. Please enjoy and share!

All segments ready!

The 18th and final primary mirror segment is installed on what will be the biggest and most powerful space telescope ever launched. The final mirror installation Wednesday at NASA’s Goddard Space Flight Center in Greenbelt, Maryland marks an important milestone in the assembly of the agency’s James Webb Space Telescope.

Not long time ago I was wondering how exactly is the robotic arm manipulating with JWST segment. I should see this:

The team uses a robotic arm called the Primary Mirror Alignment and Integration Fixture to lift and lower each of Webb's 18 primary flight mirror segments to their locations on the telescope structure. Each of the mirrors is made with beryllium, chosen for its properties to withstand the super cold temperatures of space. Each segment also has a thin gold coating to reflect infrared light. These mirror segments will function as one when the telescope is in orbit.

To precisely install the segments, the robotic arm can move in six directions to maneuver over the telescope structure. While one team of engineers maneuvers the robotic arm, another team of engineers simultaneously takes measurements with lasers to ensure each mirror segment is placed, bolted and glued perfectly before moving to the next.
The James Webb Space Telescope must be pieced together from segments using a high-precision robotic arm.

Massive Space Telescope Is Finally Coming Together

This week, NASA is set to reach a milestone on one of its most ambitious projects. If all goes to plan, workers will finish assembling the huge mirror of the James Webb Space Telescope — an $8 billion successor to the famous Hubble telescope.
