Two things we all should be paying more attention to but probably won’t:
The Air Force’s creepy, supersecret robot minishuttle, the X-37B, is finally landing after spending more than a year orbiting the Earth.
The Earth was buzzed—in cosmic terms—by two asteroids this week. Neither was of record size or came within a record distance, but here’s the thing, the second one, 2012 KT42, was only discovered a day before its flyby! It’s among the top 20 close approaches, and we only had a day of warning! It passed between the Earth and our geosynchronous satellites.
