The NASA project NEOWISE, which has given astronomers a detailed view of near-Earth objects – some of which could strike the Earth – ended its mission and burned on reentering the atmosphere after nearly 15 years in space. On a clear night, the sky is full of bright objects – from stars, large planets and …

Imagine parallel parking a 15-passenger van into just two to three parking spaces surrounded by two-story boulders. On Oct. 20, a University of Arizona-led NASA mission 16 years in the making will attempt the astronomical equivalent more than 200 million miles away. A NASA mission called OSIRIS-REx will soon attempt to touch the surface of …
