Yesterday we installed the Side-Scoop of Joy, now that there’s enough free space in the highbay. This is a large sun shield structure mounted around the telescope; the joy is due to it allowing us to observe desirable regions, which during the Antarctic summer are very close to the sun. Because this makes the mirror much less accessible, some last mirror touch-ups were conducted first.
Plus, the mirror and scoop are both shiny. Today has a shiny theme.

The plug removed, cryostat window visible

Shutter closed
Because both are white, this doesn't look a lot different than the window

The Side Scoop of Joy
Giant mylar-covered carbon fiber structure that lets us observe very close to the sun

Lifting the scoop
It's not very heavy, but it is somewhat unwieldy

Wrestling into place
These bolts are tricky

After some slight damage had weakened it, BLAST made short work of destroying the anti-spin device rigged up for the hoist
