The sixth and final satellite in the U.S. military’s network of ultra-secure, nuclear-hardened AEHF communications relay stations has arrived in Florida for final preparations for liftoff in March on a United Launch Alliance Atlas 5 rocket, the first of nearly 20 U.S. Space Force missions planned for launch in the first year of operations for the new military service.
A Northrop Grumman Antares rocket, upgraded to carry heavier payloads into orbit, lifted off Saturday from a launch pad on Virginia’s Eastern Shore with a Cygnus supply ship in pursuit of the International Space Station with fresh food, a collection of biological and technology demonstration experiments, a zero-g baking oven, and repair gear for an aging $2 billion particle physics experiment.
A Northrop Grumman Cygnus cargo ship arrive at the International Space Station Monday carrying around 4.1 tons of supplies, experiments and small research CubeSats. The automated spacecraft was captured by the station’s robotic arm at 4:10 a.m. EST (0910 GMT) Monday to close out a two-day flight from a launch pad in Virginia.
Northrop Grumman’s Cygnus supply ship set for liftoff Saturday will deliver to the International Space Station the final hardware for a series of ambitious spacewalks later this month to install a new coolant system on the Alpha Magnetic Spectrometer, a $2 billion particle physics experiment seeking the cosmic signatures of dark matter and antimatter.
