This page lists selected events from the chronology of the James Webb Space Telescope, a planned international 21st century space observatory. It is intended to be a premier observatory of the 2020s, combining the largest mirror yet on a near-infrared space telescope with a suite of technologically advanced instruments from around the world.[1]
Timeline
- 1996: Next Generation Space Telescope initiated[2]
- 2000: NEXUS cancelled (JWST technology demo)[3][4]
- 2002: $824.8 million prime contract for NGST awarded to TRW.[5]
- September 2002: NGST named James Webb Space Telescope [6][1]
- January 2007, 9/10 technology development items pass non-advocate review.[7]
- April 2010, technical part of Mission Critical Design Review (MCDR) passes.[8]
- July 2011, James Webb project threatened with cancellation.[9][10][11][12]
- November 2011, JWST survives cancellation attempt.[13]
- 2012, MIRI instrument hand-off.[14]
- 2014, first combined test of all four instruments.[15]
- March 2014, NIRCam installed in ISIM [16]
- February 2016, hexagonal segments of the primary mirror completed.[17]
- December 2015, contract for JWST's launcher signed.[18]
- March 2016, cryogenic testing of instruments and mirrors completed.[19]
- November 2016 JWST construction completed[20]
- October 2018 planned launch as of 2016.[1]
After-launch plan
- For 30 days after launch it takes a million mile trip to L2 halo orbit[21]
- For 6 months JWST is prepared for full-time science operation.[22] This includes letting everything cool down, calibrating the mirrors and instruments, etc.[23]
- 5 year science mission starts after 6 months (goal)[24]
