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.

Jet Propulsion Laboratory scientists aren't sure what to expect, but they think it's nearing interstellar space. In 1977, Jimmy Carter moved into the White House, "Star Wars" and "Saturday Night Fever" premiered in theaters and the Voyager 1 and 2 spacecraft launched from Florida's Cape Canaveral to explore the outer solar system.

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.

Television news didn't seem to fully recognize the importance of the first human to walk on the moon on the weekend he died. In the hours after Armstrong's death was announced, news networks were airing canned programming - jailhouse documentaries, a rerun interview with Rielle Hunter, Mike Huckabee's weekend show. Menacing satellite pictures of Tropical Storm Isaac had much more air time than Armstrong's dusty hops on the lunar surface. Talk of the upcoming GOP national convention sucked up the air.

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.

Scientists have located a galaxy that gives births to more stars in a day than ours does in a year. Astronomers used NASA's Chandra X-Ray telescope to spot this distant gigantic galaxy creating about 740 new stars a year. By comparison, our Milky Way galaxy spawns just about one new star each year.
