How is the most recent deployment step for Webb displayed?
The MOST RECENTLY COMPLETED deployment step for Webb is displayed along a line that also indicates the major deployment phases. Note that the timing, duration and/or order of deployment phases and steps may change. This page shows the default/nominal timing and order. The phases mark the start and end of major groups of deployment steps.
Where do the speed and distance numbers in Webbs data come from?
The numbers are derived from precalculated flight dynamics data that models Webbs flight up to its entry into L2 orbit. The distance numbers displayed are the approximate distance travelled as opposed to altitude. All the speed and distance data is with respect to an Earth-centered coordinate system.
What are the units of time on the Webb timeline?
The units are days. There are 30days on the timeline. Webb enters its L2 orbit at approimately 29.5days on the timeline. Note on smaller screens the labels are progressively removed. On portrait mobile screens of 300-600px wide only the units days is displayed. NEW! Instrument Temperatures
How long does it take Webb to reach L2?
We refer to deployment events in terms of launch + elapsed-time so this view is useful for tracking deployments and time progress. Webb enters its L2 orbit at approximately 29.5days on the timeline.
Is Webb in prime condition for the next major deployment step?
This will ensure Webb is in prime condition to begin the next major deployment step in its unfolding process. Specifically, the team is analyzing how the power subsystem is operating now that several of the major deployments have been completed.
How long does it take to deploy Webb to L2?
On its ~1,000,000 mile journey to L2 Webb will go though the major deployment steps shown above (there are many sub-steps not shown). Explore each of the major steps by clicking above and then using the additional info buttons below to see more images, video and related pages. Where Is Webb?
What is NASA’s Webb Telescope?
At a cost of nearly $10 billion, Webb is the most expensive science spacecraft ever built and by far the most powerful space telescope, 100 times more sensitive than the 31-year-old Hubble, the observatory it will eventually replace.
What has been Webb’s first month in space been like?
As we look back on Webb’s first month in space, we asked Bill Ochs, Webb project manager, to share with us his thoughts on the mission so far: “It has been about a month since launch, and it has been an unbelievable ride. I am so filled with pride for our team. The deployments could not have gone more perfectly.
Utilizing thrust every three weeks or so from small rocket engines aboard Webb will keep it orbiting L2, looping around it in a halo orbit once every six months. “So, why did the Ariane not give Webb more energy and why did Webb need course correction?
How long does it take for Webb to reach its orbit?
It will take roughly 30 days for Webb to reach the start of its orbit at L2, but it will take less than a day to get far away from Earth and much of the way there.
What happens to Webb when it reaches L2?
During the trip to L2, Webb will be fully deployed, will cool down to its operating temperature, and its systems will begin to be checked out and adjusted. These check-out procedures will continue until 6 months after launch, at which point routine scientific operations will begin.
Why is the Webb Telescope in L2 orbit?
However, at L2, exactly lined up with both the sun and Earth, the added gravity of the two large bodies pulling in the same direction gives a spacecraft an extra boost of energy, locking it into perfect unison with the Earths yearly orbit. The Webb telescope will be placed slightly off the true balance point, in a gentle orbit around L2.
How long does it take to get to L2?
Webb is currently 18 days into a 29-day journey to L2, although it has already completed around 82 percent of the distance, according to NASAs tracker.
