Sentinel

When you have a new ICBM, you need a place to keep it, so Northrop Grumman is building a prototype silo for the US Air Force to house its next-generation LGM-35A Sentinel nuclear missile that will replace the Cold War Minuteman III.

​ESA's Sentinel-1A satellite has been struck by a fast moving space particle, creating a 40-cm-wide impact crater in one of the probe's twin solar arrays.
