Kefir bacteria and yeast. Scanning electron micrograph (SEM) of Lactobacillus bacteria and yeast from kefir, a fermented milk beverage containing beneficial yeast as well as probiotic bacteria. Lactic acid bacteria produce lactic acid from the milk sugar lactose. The acid coagulates the milk. Yeasts produce carbon dioxide and a low concentration of ethanol (alcohol). Kefir thus tastes somewhat like an acidic carbonated drink. Magnification: x2500 when printed at 10 centimetres wide.

Aperture

A fully deployed OTIS, with the secondary mirror extended over the primary mirror, is removed from Chamber A after a successful thermal-vacuum test in 2017. Seen still in the chamber is a sunshield simulator, called the L5 Simulator, representing the fifth and innermost layer of the sunshield. The telescope would be shipped to the Northrop Grumman facility in California to be integrated with the real sunshield. I was suspended on a lift for this shot. Page 119
