The James Webb space telescope has arrived at L2

Related, NASA has a big album of photos related to the preparations &amp; launch. So many awesome shots in here: <a href="https:&#x2F;&#x2F;www.flickr.com&#x2F;photos&#x2F;nasawebbtelescope&#x2F;albums&#x2F;72157720000770033" rel="nofollow">https:&#x2F;&#x2F;www.flickr.com&#x2F;photos&#x2F;nasawebbtelescope&#x2F;albums&#x2F;72157...</a>

&gt;The remaining five months of commissioning will be all about aligning the optics and calibrating the scientific instruments<p>Plenty of time for the mirror to cool down.<p>It is interested that we have 2 projects with huge solar shields; JWST and the Parker probe

Basically, the mirrors are still glowing white-hot, for a value of &quot;white&quot; that matters to an eye that sees in a spectrum consisting mostly of infrared.

Serious question, how does it stop when it gets to the right place? Does it have to thrust in the opposite direction or does it use some gravitational effect to slip into orbit?

Good BBC article at <a href="https:&#x2F;&#x2F;www.bbc.co.uk&#x2F;news&#x2F;science-environment-60116475" rel="nofollow">https:&#x2F;&#x2F;www.bbc.co.uk&#x2F;news&#x2F;science-environment-60116475</a>

I actually thought we chose L2 so that JWST could be shielded from the Sun by the Earth to keep it ultra cool. I didn’t realize it was solar powered.

Does anyone know why JWST will orbit around L2 instead of being parked at L2? (Is it even possible to be parked directly on top of L2?)
