FAIRFIELD-SUISUN, CALIFORNIA University of Arizona asteroid hunters overcome virus, wildfire in record year of discoveries [The Arizona Daily Star, Tucson] Feb. 15 Asteroid hunters from the University of Arizona set another record in 2020, despite a pair of earthly threats to their early-warning telescopes high in the Catalina Mountains. The NASA-funded Catalina Sky Survey identified 1,548 new near-Earth objects last year, the most productive year in the decades-old search for dangerous space rocks in our immediate cosmic neighborhood. To reach the new mark, survey members had to overcome a weeklong coronavirus shutdown in the spring. Then came the massive Bighorn Fire, which chased them off the mountain for three weeks and nearly burned down their telescopes.
