It might be possible to catch an asteroid, place it into Earth orbit, and thus provide a ready source of precious metals and water for space colonists to use. - The fireball meteor streaking across the sky the early evening of January 17, 2018, witnessed by 700 observers in 11 States and Canada was also recorded by infrasonic microphones and seismometers. Scientific studies of this event gives researchers the ability to assess the risks presented by the 2,000 large fireball meteor explosions which occur each year world wide and will allow scientists to detect any secret nuclear tests being conducted by rogue individuals or governments.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
