   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.
