The page constantly updates as Webb travels, deploys, cools to operating temperature and moves through its commissioning phases ultimately leading to the release of its first images. One can also explore Webb's location in 3d in a 3d solar system ( and compare it to Hubble and other spacecraft in 3d). WhereIsWebb also tracks Webb's current deployment/commissioning state and status of that state with updates as well as the overall schedule and sequence of major deployment and commissioning phases.
It will continue to track temperatures through the commissioning. Part of the way through its journey to L2 WhereIsWebb will start tracking Webb's cooldown to operational temperatures and the dramatic contrasts in temperatures from its hot side to its cool side. Post launch and until Webb reaches it's station orbitting L2, WhereIsWebb tracks Webb's journey to L2 tracking its speed and distance from Earth and L2. WhereIsWebb tracks Webb's flight to L2 in the weeks immediately after launch, its cooldown to operating temperature, major deployment/commissioning schedule phases, its current deployment/commissioning state and status of that state, as well as providing users with a 3d model of where Webb is located in a 3d solar sytem. 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. On the you can Deployment Explorer page you can explore all past and upcoming deployments on the way to L2. At this point the top of the page will show a set of bellweather current daily temperature obsevations followed by plots of those temperatures.
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. 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. 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. It’s perfect for situations where you have to time something in a pinch.Īnd yes you can also use the ‘time’ command to literally time the completion of commands as well, but that’s a topic for another article.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. No need for downloads or utilities, if all you need is a simple stop watch just turn to the command line.
NIFTY STOPWATCH MAC OS
This uses the time command and thus works in basically every version of macOS, Mac OS X, Linux, and it should also work in just about any other version of unix that supports the time and cat commands as well. How this stopwatch works is that you are using the ‘time’ command to measure the time of how long another command takes to execute, but since the cat command requires something to output and we are not providing anything, cat does nothing, thus creating a simple stopwatch. The top ‘real’ number is the elapsed time, that is, time that passed since executing the command. Once the stopwatch has ended running, you will return to the command prompt while returning something back that looks like this: To get started, launch the Terminal application, and then type the following following command string:Īt any point, you can stop the counting stopwatch by hitting Control-C on the keyboard. Try it yourself, this stopwatch trick is super easy.
