  • Eyes on: Watching NASA Work on the JWST with ‘Webb-cam’

    Larry KlaesJune 5th, 2017

    NASA has continued its very popular "Webb-cam" monitoring of the James Webb Space Telescope (JWST) with a special Webb camera installed in NASA's Johnson Space Center clean room in front of the massive thermal vacuum testing chamber known as Chamber A.

  • James Webb Space Telescope prepares for deep freeze

    SpaceFlight InsiderMay 15th, 2017

    The James Webb Space Telescope (JWST) continued its long and meandering journey to space with a stop in Houston, Texas. The telescope has been moved to Johnson Space Center so it can undergo the last cryogenic test before the massive observatory is launched into space in 2018.

  • NASA’s James Webb Space Telescope completes testing at Goddard

    Jim SharkeyMay 5th, 2017

    NASA's James Webb Space Telescope (JWST) successfully completed the center of curvature test, a crucial optical measurement of the telescope's primary mirror prior to cryogenic testing, and the final test at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

  • James Webb Space Telescope will search TRAPPIST-1 planets for signs of life

    Laurel KornfeldMarch 3rd, 2017

    The seven Earth-sized planets discovered last month orbiting the star TRAPPIST-1 will be ideal targets for the James Webb Space Telescope (JWST), scheduled for launch next year, to probe in a search for signs of life.

  • Trump space advisors considering Hubble servicing mission

    Bart LeahyFebruary 16th, 2017

    The Wall Street Journal reports that Trump administration advisers are considering a public-private crewed mission aboard the Sierra Nevada Corporation (SNC) Dream Chaser spacecraft to keep the aging Hubble Space Telescope (HST) operational. The proposed mission, which would not happen before 2019, would require support from the next NASA administrator.

  • ‘Anomalous readings’ detected during James Webb Space Telescope tests

    Scott JohnsonDecember 19th, 2016

    Earlier this month, on Dec. 3, accelerometers at NASA's Goddard Space Flight Center (GSFC) detected "anomalous readings" in a portion of the James Webb Space Telescope (JWST). These "readings" took place during vibration tests being conducted to simulate anticipated launch conditions.

  • James Webb Space Telescope nears completion

    Scott JohnsonNovember 7th, 2016

    GREENBELT, Md. — On Nov. 2, NASA celebrated the completion of the OTIS (Optical Telescope, plus Integrated Science instrument module) portion of the James Webb Space Telescope during a "Golden Mirrors" media event in Building 29 at Goddard Space Flight Center. SpaceFlight Insider was on hand for the event.

  • Final layer of sunshield completed for NASA’s James Webb Space Telescope

    Jim SharkeyNovember 2nd, 2016

    NASA recently announced the completion of the fifth and final sunshield layer responsible for protecting the instruments and optics of the James Webb Space Telescope (JWST). The sunshield, designed by Northrop Grumman in Redondo Beach, California, will prevent heat from the Sun from interfering with the telescope's infrared sensors.

  • Our SpaceFlight Heritage: JWST – the once and future thing

    Mackenzie KaneSeptember 18th, 2016

    Conceived in 1989 by the Space Telescope Science Institute and backed by NASA’s Goddard Space Flight Center, the Next Generation Space Telescope, predecessor to the James Webb Space Telescope, was to succeed the Hubble Space Telescope. The journey that the JWST would take has been a long and winding one.

  • James Webb Space Telescope now fully equipped with science instruments

    Laurel KornfeldMay 29th, 2016

    A team of some two dozen NASA technicians and engineers have successfully installed the package of four science instruments that will accompany the James Webb Space Telescope.

  • Completion of primary mirror marks milestone for James Webb space telescope

    Laurel KornfeldFebruary 11th, 2016

    The James Webb Space Telescope, dubbed the successor to the Hubble Space Telescope, and the most powerful space-based observatory ever constructed, reached a major milestone recently when its 18th and final primary mirror was installed on February 3.

  • James Webb Space Telescope mirror installation halfway complete

    Jim SharkeyDecember 31st, 2015

    NASA recently announced that the ninth flight mirror of the James Webb Space Telescope (JWST) has been installed, marking the halfway completion point of the segmented primary mirror. Engineers working in the massive clean room at NASA's Goddard Space Flight Center used a robotic arm to place the mirror onto the telescope structure. The first of 18 mirror segments was installed in November.
