Where is Webb?

LOADING ...

This page tracks Webb on its journey from Earth to entry into its L2 halo orbit through all steps of its commissioning and finally to the delivery of its first science images.

While Webb is in flight to L2, it's journey is tracked numerically at the top of the page showing its progress in distance, speed, percentage of trip complete to L2. Below those numbers, is a timeline switchable between DAYS/DISTANCE since launch, a thumbnail of Webb's MOST RECENTLY COMPLETED deployment step marking its place in TIME or DISTANCE on its 30 day journey to L2 followed by details of the current deployment step shown with a larger image, info and links.

Once Webb has reached L2, this page will transition to tracking Webb's commissioning steps including the vital process of cooling to operating temperatures and mirror alignment, followed by instrument commissioning. At this point the top of the page will show a set of bellweather current daily temperature obsevations followed by plots of those temperatures.

On the you can Deployment Explorer page you can explore all past and upcoming deployments on the way to L2. The Deployment Explorer opens to the MOST RECENTLY COMPLETED deployment step, all deployment steps to the "left" (on the top thumbnail nav) are COMPLETED, ll deployment steps to the "right" (on the top thumbnail nav) are FUTURE.
