The launch of the NASA/ESA/CSA James Webb Space Telescope (Webb) on an Ariane 5 rocket from Europe’s Spaceport in French Guiana is now planned for October 31, 2021.
NASA has announced the decision, based on a recently completed schedule risk assessment of the remaining integration and test activities before launch, accounting for impacts from the COVID-19 pandemic and technical challenges. Previously, Webb was targeted to launch in March 2021.
