They illustrate the great contrast between the hot and cold sides of the spacecraft and the incredible engineering and effectiveness of the sunshield. These temperature observations are reported daily from actual spacecraft telemetry data. Temperature values will continue to be reported in the months that follow the completed deployment as the spacecraft cools to operational values. But Webb never actually arrives at L2, it is travelling to enter an orbit around L2. Webb's L2 orbit is very large in size and it enters its orbit before it reaches the linear distance between Earth and L2.

Webb's orbit around L2 is known as a halo orbit which, rather than a single path, is an orbit that periodically varies through a series of paths around L2. By design, the launch vehicle and Webb's trajectory put Webb on a path to an L2 orbit with only small inputs needed to refine it. As it separates from the upper stage of the launch vehicle, Webb is climbing the gravity ridge from Earth up into a halo orbit around L2. Once Webb is in its halo orbit it will be riding up and down and over and along the shallow saddle contour at L2.

To get the exact orbit needed, Webb's trajectory is fine tuned by a number of "burns" along the way. Therefore, this page, for purposes of calculations uses a distance to L2 orbit entry number and timing that is a sufficient distance and time after the MCC2 burn to say "Webb is in L2 Orbit".

Once in L2 orbit, this page will no longer track distance, but will track temperatures. The spacecraft will continue to cool to operating temperatures and numerous tests and calibrations occur to ready it for operations and its first images over the months that follow.

For example, a web tool can do any of the following: Calculate the probable evacuation area for a hazardous chemical spill Calculate the predicted track and strength of a hurricane Generate a report of land cover and soils within a specified watershed Produce a parcel map with historical details of ownership Geocode an address and feed into a permitting application for a home renovation system Any user connected to the ArcGIS Enterprise portal can access and use the web tool.

Author, publish, and use web tools The following sections describe the process for authoring, publishing, and using a web tool. Author To author a web tool, you typically create and document a geoprocessing tool using ModelBuilder or Python.

Learn more about authoring web tools Publish Once you've authored a tool, you must next run it in ArcGIS Pro , and the tool must complete successfully. Learn more about publishing web tools Use After publishing the web tool, it can be used in any client app that connects to the portal.
