FreeFlyer Team Visits 2022 AAS/AIAA Astrodynamics Specialist Conference to Present on James Webb Space Telescope
September 29, 2022
Members of a.i. solutions FreeFlyer team recently had the pleasure of attending the 2022 AAS/AIAA Astrodynamics Specialist Conference in Charlotte, North Carolina. While at the conference, not only did the team have the opportunity to share the latest updates on FreeFlyer, select members presented a variety of white papers on industry-related topics covering a variety of details about the James Webb Space Telescope.

Flight Dynamics Planning and Operations Support for the JWST Mission
September 29, 2022
The James Webb Space Telescope (JWST) was launched from Kourou Spaceport on December 25, 2021, at 12:20 UTC on an Ariane 5 launch vehicle. The launch vehicle inserted JWST into a 30-day transfer trajectory to the Sun-Earth-Moon (SEM) Lagrange point L2 region. JWST executed three mid-course correction maneuvers (MCCs) to insert the spacecraft into a quasi-halo orbit about SEM L2; JWST will maintain its trajectory about L2 for at least 5.5 years, with a goal of at least 10.5 years. This paper summarizes the flight dynamics support for JWST, including the prelaunch nominal trajectory design, the launch window analysis, contingency planning for trajectory-related anomalies, mission operations support for the first 6 months, and a comparison of the planned and achieved actual JWST trajectory results. The orbit determination strategy, both planned and executed, will be summarized, and the method of addressing the anomalies as they occurred will be included.
