Travelers in the Night Eps. 901 & 902: Rubin And Incoming Asteroids & Lighting Up The Night

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org From May & June 2026. Today's 2 topics: - However, according to a recent research project, the Rubin Observatory will discover but not give an adequate warning time for objects destined to hit the Earth. To provide time to take action to deflect an incoming object we will need to rely on ground based telescopes used by my Catalina Sky Survey teammates and other asteroid hunting groups as well as NASA's NEO Surveyor satellite when it is launched. - A start up company Reflect Orbital is proposing to launch 50,000 satellite mirrors by 2035 to illuminate solar panels on Earth all night long. This would be devastating for human sleep cycles, birds, insects, plants and many of the biological systems of organisms on which we all depend.
