    The James Webb Space Telescope, in development for the past 22 years, is now scheduled to take flight on March 30, 2021. Known for its numerous delays and cost overruns, the JWST appears to be in the final stages for its flight atop an Ariane 5 rocket from Kourou, French Guiana.

  • James Webb Space Telescope to study Jupiter’s Great Red Spot

    Laurel KornfeldJune 26th, 2018

    When NASA's James Webb Space Telescope (JWST) launches in May 2020, one of its first targets is expected to be Jupiter's Great Red Spot, a large storm believed to have been active on the giant planet for more than 350 years.

  • NASA announces James Webb Space Telescope Independent Review Board members

    Jim SharkeyApril 12th, 2018

    NASA recently announced the formation of an external Independent Review Board for the space agency's James Webb Space Telescope (JWST). The board will study a variety of factors impacting the mission's success and reinforce NASA's strategy for completing the observatory's final integration and testing phase, launch phase and commissioning.

  • NASA delays launch of James Webb Space Telescope to 2020

    Laurel KornfeldMarch 28th, 2018

    The highly anticipated launch of NASA's James Webb Space Telescope (JWST) has been delayed to May 2020 due to the need for extensive testing and integration of its parts, which the agency says it now recognizes will take longer than previously anticipated.

  • Two halves of James Webb Space Telescope come together for testing in California

    Curt GodwinFebruary 6th, 2018

    After years of development, and having undertaken rounds of discrete testing, the two major components of NASA's James Webb Space Telescope (JWST) have arrived in California for fully-integrated testing. The flagship mission is referred to as the scientific successor to the stalwart Hubble Space Telescope (HST) and is set to launch on an Arianespace Ariane 5 rocket in the Spring of 2019 from Kourou, French Guiana.

  • James Webb Space Telescope comes in from the cold after final cryogenic test
