The first catalogued fragments of shattered satellite Cosmos 2251 are about to re-enter Earth’s atmosphere. According to US Strategic Command tracking data, reentries will occur on March 12th, 28th and 30th, followed by more in April.
Radar cross sections are not available for all of the reentering pieces; they are probably centimeter-class fragments that pose no threat to people on the ground. Visit spaceweather.com for more information.
Tonight’s full Moon has a special name—the Worm Moon. It signals the coming of northern spring, a thawing of the soil, and the first stirrings of earthworms in long-dormant gardens. Step outside tonight and behold the wakening landscape. “Worm moonlight” is prettier than it sounds.
