NASA’s Cassini probe is doomed. The nuclear-powered robot — part of a $3.26 billion, three-decade-long effort — has orbited Saturn for nearly 13 years. But it’s running dangerously low on fuel. Continue reading

NASA’s Cassini spacecraft sped by the moon Titan on Saturday, using the hazy world’s gravity to slingshot the probe on a trailblazing trajectory to explore the region between Saturn’s hydrogen-helium atmosphere and the planet’s famous rings for the first time. Continue reading

A Long March 7 rocket lifted off Thursday with Tianzhou 1, an unpiloted refueling freighter heading for China’s Tiangong 2 mini-space station to conduct several months of robotic demonstrations, practicing for the assembly and maintenance of a future permanently-staffed orbital research complex.

We examine the possibility that Fast Radio Bursts (FRBs) originate from the activity of extragalactic civilizations. Our analysis shows that beams used for powering large light sails could yield parameters that are consistent with FRBs. The characteristic diameter of the beam emitter is estimated through a combination of energetic and engineering constraints,
