PASADENA, Calif. (AP) — Cheers and applause echoed through the NASA Jet Propulsion Laboratory in Pasadena on late Sunday after the robotic explorer Curiosity signaled it had survived a harrowing plunge through the thin Mars atmosphere. The most high-tech interplanetary rover ever built touched down on the Martian surface inside of a giant crater after a tricky landing routine that included a series of braking tricks, a heat shield and a supersonic parachute.

MOSCOW (AP) — An unmanned Russian cargo spacecraft (similar to the one pictured here) has redocked with the International Space Station after an aborted attempt five days earlier. The Progress cargo ship had separated from the station a week ago to perform engineering tests and try out a new docking system and had been due to reconnect with the station on Tuesday. But problems developed with the avionics in the docking system. The second attempt early Sunday was successful. Video streamed from Russian mission control reported no problems.

We now know that Pluto, the dwarf planet formerly known as a planet, has one more moon orbiting it. Using the Hubble Space telescope, astronomers have discovered Pluto's fifth moon.

NPR's Joe Palca filed this report for our Newscast unit:

"The new moon is tiny, something between 6 and 15 miles across. It showed up in nine separate images the space telescope made in the last month. The latest image came earlier this week.
