Space Mechanic | Today's Space News

Astronomy Daily — S05E147: "Space Mechanic" Wednesday 22 July 2026 A spacecraft with robotic arms is on its way to geostationary orbit to keep other satellites alive. A discarded rocket stage is two weeks out from hitting the Moon, and twenty-three astronomers have just asked the world to watch. Plus the first binary star system where both stars exploded, the first complete magnetic map of a galaxy cluster, and the asteroid breakup that may have bombarded three worlds while Earth froze. In This Episode ● The Space Mechanic Launches — Northrop Grumman's Mission Robotic Vehicle lifted off from Cape Canaveral on 21 July carrying three Mission Extension Pods. With two 3-metre robotic arms built by the US Naval Research Laboratory, it is designed to inspect, relocate, repair and refuel satellites in geostationary orbit. Each pod can give a 2,000 kg satellite up to eight more years of life. ● UPDATE — The Rocket Aimed at the Moon — A new arXiv preprint signed by 23 astronomers calls for a coordinated observing campaign when Falcon 9 upper stage 2025-010D strikes the Moon near Einstein crater on 5 August. North America has the best seat: 2:34am EDT, with the paper naming observers in the Americas as the ideal group. Refined impact time, predicted crater size, and why the ejecta plume may be visible even if the flash is not. ● Sibling Supernovae — Sixteen years of Fermi data reveal a faint supernova remnant hiding in the glare of the Jellyfish Nebula. The two may be the first known pair of remnants traced back to a single binary star system. ● Mapping a Cluster's Magnetic Field — Using the deepest radio observations ever made with LOFAR, astronomers have reconstructed the magnetic field of galaxy cluster Abell 2255 from nucleus to outer edge for the first time. ● The Eulalia Bombardment — A new Planetary Science Journal paper links the breakup of a main-belt asteroid to an impact shower that battered the Moon, Earth and Mars 800 million years ago — and may connect to a global freeze. ● Skywatch, Both Hemispheres — Why this week beats peak night for the Delta Aquariids wherever you are, how to catch them from the southern US and Mediterranean, and what's coming on 12 August: a total solar eclipse across Iceland and Spain, a North American partial, and the best Perseid peak in years on a new Moon.
