Hi All,

Today, at 2 p.m. EST, Webb fired its onboard thrusters for nearly five minutes
(297 seconds) to complete the final postlaunch course correction to Webb's
trajectory. This mid-course correction burn inserted Webb toward its final
orbit around the second Sun-Earth Lagrange point, or L2, nearly 1 million miles
away from the Earth.

The final mid-course burn added only about 3.6 miles per hour (1.6 meters per
second) - a mere walking pace - to Webb's speed, which was all that was needed
to send it to its preferred "halo" orbit around the L2 point.
