Ever the optimist! You can probably get treatment for that. :)<br>
<br>
NASA says six months, plus one month's work done during the journey to L2.<br>
<br>
See: <<a href="https://www.nasaspaceflight.com/2021/11/commissioning-jwst-1/" rel="noreferrer" target="_blank">https://www.nasaspaceflight.com/2021/11/commissioning-jwst-1/</a>><br>
Quotes:<br>
“It takes probably three to four months to get everything down to the<br>
30 to 50 Kelvin temperature ranges that [most instruments] need. But<br>
during that time, our optical team is continuing to align the<br>
telescope.<br>
<br>
After this, James Webb gets turned over to the instrument teams.<br>
“We have four instruments, and [those teams] will then go through a<br>
series of calibration exercises with those instruments. These<br>
exercises range from thermal stability measurements to looking at dark<br>
areas to just calibrating out all of the artifacts in the instruments<br>
that would interfere with science observations.”<br>
<br>
This delicate work will take about two months, bringing the total<br>
commissioning phase to about six months total.<br>
---------<br>
<br>
You will have to be patient for a while and hope everything checks out OK.<br>
<br>
