2. Space sunshade - Wikipedia

   en.wikipedia.org/wiki/Space_sunshade

   A sunshade could potentially be one climate engineering method for mitigating global warming through solar radiation management, because internationally negotiated reductions in carbon emissions may be insufficient to stem climate change. [5] [6] Sunshades could also be used to produce space solar power, acting as solar power satellites ...

3. Sun protective clothing - Wikipedia

   UPF (ultraviolet protection factor) represents the ratio of sunburn-causing UV without and with the protection of the fabric, similar to SPF (sun protection factor) ratings for sunscreen.

   The temperature differences between the hot and cold sides of the James Webb Space Telescope five-layer sunshield. The sunshield acts as large parasol allowing the main mirror, optics, and instruments to passively cool to 40 kelvins (−233 °C; −388 °F) or cooler, [6] and is one of the enabling technologies that will allow the JWST to operate.
