The launch of the James Webb Space Telescope will not happen in March 2021 — the mission’s previously-scheduled launch date — after the coronavirus pandemic forced a more than 50 percent reduction in staff levels at the observatory’s assembly and test facility.

NASA awarded Northrop Grumman a contract worth as much as $84.5 million earlier this month to supply rocket motors for a first-of-its-kind launch vehicle to fire a capsule of rock samples off of Mars on a journey back to Earth.

An independent panel has informed NASA that the James Webb Space Telescope will not be ready for launch until March 2021, and Congress will have to reauthorize the long-delayed, over-budget mission after breaching an $8 billion cost cap, officials said Wednesday.
