Dust from Asteroid Mining Could Turn Into Another Space Junk Hazard

There is gold out there on asteroids. Silver and platinum and titanium, too. And if we’re seriously going to mine asteroids, it might be easier to tow them closer to Earth. But that could be serious trouble for satellites, according to new calculations by astrophysicists. Read More >>

Amateur Satellite Trackers Found the Secret X-37B Space Plane in Orbit

The US Air Force’s super-secret X-37B was launched into orbit for the fourth time last week, and amateur satellite watchers have promptly identified its secret orbit — also for the fourth time. There is, you see, a small army of amateurs who keep track of over 300 spy satellites, often with little more than a pair of binoculars. Read More >>

Saving the Last of the World’s Glaciers by Sending Them to Antarctica

Glaciology is in the middle of a slow-moving crisis. As the climate warms, glaciers are shrinking and then disappearing. So scientists have come up with a plan to put ice cores from melting glaciers in the most permanent cold storage possible on Earth: in Antarctica. Read More >>
