Pluto passed in front of a star on the evening of August 14. Mat Kaplan joined pro and amateur astronomers on a mountain to observe this rare event. It may reveal more about the dwarf planet’s tenuous atmosphere and other properties. Everyone hopes that Mars Exploration Rover Opportunity will phone home when the waning worldwide Martian dust storm allows the robot to charge its batteries. Digital Editor Jason Davis tells us about the online mistake that had some fans believing it had already happened. And it will be “raining fire in the sky” when Bruce Betts drops another What’s Up segment.
