NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft has spotted a never-before-seen comet -- its first such discovery since coming out of hibernation late last year.
Process Could Allow Satellites To Be Replenished In Orbit
NASA has successfully concluded a remotely controlled test of new technologies that would empower future space robots to transfer hazardous oxidizer – a type of propellant – into the tanks of satellites currently in orbit. Concurrently on the ground, NASA is incorporating results from this test and the Robotic Refueling Mission on the International Space Station to prepare for an upcoming ground-based test of a full-sized robotic servicer system that will perform tasks on a mock satellite client.
