Coronavirus And Schools, New Mars Rover. July 17, 2020, Part 1

As we approach August, many of our young listeners and their parents are starting to think about going back to school. Usually, that might mean getting new notebooks and pencils, and the excitement of seeing classmates after a summer apart. But COVID-19 makes this upcoming school year different. Big districts, including Los Angeles and San Diego public schools, will be completely remote this fall. Other districts are looking at hybrid programs, with some time in the classroom and some at home. Still others want kids to return to the classroom full-time. The Centers for Disease Control and Prevention says schools should adjust plans based on how many coronavirus cases are in the community. Schools with little transmission may be able to go back to the classroom, but with more sanitation efforts and no sports events. For communities with high levels of spread, the CDC says stronger measures are needed, like staggered arrivals and dismissals, kids staying in one classroom, or all-remote education. However, Vice President Mike Pence said this week that CDC guidance should not dictate whether schools open for in-classroom instruction. Joining Ira to talk about what to consider in back-to-school plans are Pedro Noguera, dean of the Rossier School of Education at the University of Southern California in Los Angeles, and Laura Fuchs, a high school history teacher and secretary of the Washington Teachers’ Union in Washington, D.C. In just a few weeks, NASA is scheduled to launch its newest rover in the direction of Mars. Perseverance, the formal name for the Mars 2020 mission’s rover, is now safely at Cape Canaveral, strapped to its Atlas V rocket, waiting only for the launch window to open. If all goes well, Perseverance will begin roving Mars next February. Once on Mars, it will join its cousin Curiosity in combing through the dust and rocks of the red planet—but where Curiosity hunts inside a meteor crater for water and other signs of suitability for life, Perseverance will scour an ancient river delta for the traces left by potential microscopic life. Ira talks to two Perseverance masterminds, deputy project scientist Katie Stack Morgan and aerospace engineer Diana Trujillo, about the challenges of building for space exploration, and what it takes to conduct science experiments 70 million miles from Earth.
