A sophisticated communications satellite launches into orbit atop an Atlas 5 rocket Sunday to bring residential high-speed Internet to parts of the U.S. that must look to space for connectivity.

The most powerful Atlas rocket to ever fly from the West Coast is poised for launch Thursday to deliver a secret payload into orbit while debuting a new upper stage engine.

Track the progress of the MASCOT lander, a tiny robot developed in Germany and France, as it explores asteroid Ryugu for a daring mission to hop across the austere world’s boulder-strewn landscape, taking pictures and collecting scientific data along the way. The robotic probe was released from the Hayabusa 2 spacecraft around 0200 GMT Wednesday (10 p.m. EDT Tuesday), and touched down a few minutes later.
