  1. NASA Releases Timelapse Showing 9 Months of Testing The James Webb Space Telescope

    The James Webb Space Telescope has successfully finished nine months of testing at NASA’s Johnson Space Center in Houston.

    In order to get it ready for space, the JWST was placed inside a giant cryogenic vacuum chamber and exposed to extremely cold temperatures, to simulate the conditions it will eventually experience.

    As you can see from the video, a lot goes into getting 19 massive hexagonal mirrors ready for seeing into the most distant parts of the universe.

    Up next for the James Webb Space Telescope is to undergo even more testing at defense contractor Northrop Grumman’s facility in Redondo Beach, California, the JWST’s primary contractor.

    After attaching other pieces and completing the observatory, the telescope will nearly be ready for its 2019 launch.

  2. Launch of NASA’s James Webb Space Telescope Delayed Until Spring of 2019

    NASA’s James Webb Space Telescope is no stranger to launch delays.

    The latest sees it moved from the previously planned launch of October 2018 to Spring of 2019, sometime between March and June of 2019.

    According to NASA, this delay stems from component integration and testing taking longer than expected.

    Eric Smith, program director for the James Webb Space Telescope, notes, “The installation of more than 100 sunshield membrane release devices, factoring in lessons learned from earlier testing, like longer time spans for vibration testing, has meant the integration and testing process is just taking longer.”

    “The change in launch timing is not indicative of hardware or technical performance concerns,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate in a statement.

    Once the long-awaited James Webb finally does launch, it will be capable of doing some miraculous things, namely seeing deep into space and observing galaxies formed right after the Big Bang through infrared.

    Measuring 21-feet across, the telescope will be the largest and most powerful ever built, and an absolute gift to astronomers all over the world.
