NASA’s Powerful Webb Telescope is now fully aligned and it is getting ready for the instrument commissioning phase. After a thorough review, it has been confirmed that it can now capture crisp and well-focused images with its 4 effective and highly sensitive onboard instruments.
Upon finishing the 7th and very last stage of telescope alignment, the concerned team has decided that Webb is ready to move into its final series of preparations called science instrument commissioning. This will take approximately 2 months before scientific operations planned in the summer take place.
The alignment of the telescope across all of its onboard instruments can be seen in a sequence of pictures that captures the observatory’s complete discipline of view.
“These remarkable test images from an effectively aligned telescope shows what humans across different countries and continents can achieve when they have a clearer and bolder scientific view to discover the universe,” stated Lee Feinberg, Webb optical telescope element manager at NASA’s Goddard Space Flight Center.
How Is JWST’s Optical Performance?
The overall optical performance of the telescope is still higher than the engineering group’s maximum positive predictions. Webb’s mirrors are presently directing fully focused light gathered from the space down into every instrument, and each one is effectively captured with the light being directed to them.
The quality of pictures which is delivered to all the Webb’s instruments is “diffraction-limited,” which means that the fineness of detail that may be visible is as good as physically possible, looking at the size of the telescope. From this point moving forward, modifications in the mirrors may be very few like periodic adjustments in the primary mirror segments.
“With the completion of telescope alignment and 1/2 of a lifetime well worth of effort, my position at the James Webb Space Telescope task has come to an end,” stated Scott Acton, Webb wavefront sensing and controls scientist. “These pictures have profoundly changed the way I see the universe.
We are surrounded through a symphony of creation; there are galaxies everywhere! It is my wish that everybody in the world can see them.”
What Does The Webb Team Planning?
The Webb team will now focus on commissioning scientific instruments. Each instrument is a very sophisticated set of detectors armed with unique lenses, masks, filters, and other equipment that aids in the performance of the research it was created to accomplish.
What Will Happen During The Instrument Commissioning?
During the instrument commissioning phase, the specialized characteristics of these instruments will be configured and operated in various combinations to fully confirm their preparedness for science.
With the formal completion of telescope alignment, important people engaged in the commissioning of each instrument have arrived at the Space Telescope Science Institute’s Mission Operations Center in Baltimore, and also some personnel which are involved in this alignment process have finished their duties.

Despite the fact that telescope alignment is accomplished, there are still certain telescope calibration tasks to be completed. The telescope will be ordered to point to different places in the sky where the total amount of solar radiation striking the observatory will fluctuate as part of scientific instrument commissioning to ensure thermal stability when changing targets.
In addition to this, every two days, maintenance observations will monitor the mirror alignment and, if required, make necessary changes to keep mirrors in their aligned positions.
