The NASA rover Curiosity has beamed back pictures of bedrock that suggest a fast-moving stream, possibly waist-deep, once flowed on Mars -- a find that the mission's chief scientist called exciting.

The eXtreme Deep Field (XDF) focuses on a small patch of the constellation Fornax, containing some 5,500 galaxies. The image was culled from 10 years of photos of the same region of space shown in the Hubble Ultra Deep Field, which was last updated in 2009, based on data gathered in 2003 and 2004.

Space shuttle Endeavour landed safely at the Los Angeles International Airport Friday after a whirlwind aerial tour around California landmarks. Strapped to the back of a 747 jumbo jet, the pair touched down around 1 p.m. after a nearly five-hour flyover. One of the crew members stuck an American flag out of the hatch of the jet. The flyover took Endeavour over the state Capitol, Golden Gate Bridge, Hollywood Sign and other icons en route to the Los Angeles airport, where the shuttle will be prepped for a slow-speed journey to its museum home next month.

No, it’s not science fiction: for those who have run out of places to go, companies are competing to take amateur astronauts into the heights, and beyond.

Getting a six-wheeled car-size rover safely onto the surface of the red planet? Daunting, sure. But NASA did it with Curiosity. Sending humans on a mission to Mars? That requires overcoming even more outlandish obstacles.

David's time on Earth had come to a temporary end — and he was taking his family with him. As soon as the rover Curiosity dropped onto the Martian surface on Aug. 5, David and hundreds of his fellow scientists and engineers at NASA's Jet Propulsion Laboratory switched from Earth time to Mars time.

NASA's Curiosity rover on Wednesday left its first tracks on Mars, successfully completing a short test drive that showed it was ready to roll on longer treks for science investigations over the next two years.

NASA's Curiosity rover has zapped its first Martian rock, aiming its laser for the sake of science. During the target practice on Sunday, Curiosity fired 30 pulses at a nearby rock over a 10-second window, burning a small hole.

Curiosity phoned home throughout its daring and unprecedented landing sequence that night, giving its nervous handlers step-by-step status and health updates. The European Space Agency's Mars Express orbiter recorded some of this chatter, and now we can hear what Curiosity had to say.

Many skywatchers go through their entire lives without ever seeing the elusive planet of Mercury. Thursday morning, Aug. 16, is one of the rare opportunities when you can catch a glimpse of  it.
