Fighting Coronavirus with Llamas, Why Rain Stops Rocket Launches, and Listener Questions About Cold Things

Learn about why NASA doesn’t launch rockets in the rain (which is why there was a delay launching the SpaceX Crew Dragon spacecraft carrying NASA astronauts Robert Behnken and Douglas Hurley); why llamas are so promising for protecting humans against viruses like COVID-19; and why things get cold — when they’re wet, when you’re chewing mint gum, and when you blow air through narrowed lips.
