Recent Accomplishments
Updated February 6, 2013
The following list contains a record of program and project
accomplishments for the James Webb Space Telescope. The left column gives the original due date, the middle column gives the item accomplished, and the right column indicates the
schedule performance with green text denoting items accomplished earlier than
planned, black text for items completed on schedule, and red text for items
finishing later than planned. The list will be updated approximately every
month.
The image below points out various
major hardware components of the facility referred to in the list to orient the
reader. (Click to enlarge image.)
