Description
Space blankets reflect IR (heat) but still be a bit translucent (1-8%) - so they are great for heat shields or shades - and they weight near nothing.
 UV-B protection is >99% ⇒ perfect sunscreen.
you can make 6 + 12 = 18 (+center) tiles to build a JWST mirror Sunblocker
(btw: the JWST uses multi layer space blankets as sun shield too while the mirrors are made from gold plated beryllium)
Using 20cm skewer will make a 40cm tile the JWST config would be 8×20cm in diameter=1.6×1.75meter! Maybe using just 10-15cm skewer for this.
or just use 7 Tiles with 30cm skewer for 1.5meter (1meter with 20cm skewer).
Which is about the size of just one original JWST Hex mirror.
Use the c-clips to tighten the space blanked around the hexagon frame.
