[EX Q]: (CNN) -- X-ray data from NASA's MESSENGER probe points to high levels of magnesium and sulfur on the surface of the planet Mercury, suggesting its makeup is far different from that of other planets, scientists say. The unmanned orbiter has been beaming back data from the first planet for a year and a half. Readings from its X-ray spectrometer point to a planet whose northern volcanic plains formed through upwellings of rocks more exotic than those often found on the Earth, the Moon or Mars, said Shoshana Weider, a researcher at the Carnegie Institution of Washington. "Before this MESSENGER mission, a lot of people assumed it was very like the Moon -- it's dark, it's grey," Weider said. But while the Moon's surface formed when light materials floated to the top of an ocean of molten rock, the low level of calcium on Mercury indicates that didn't happen there.NASA probe gives insight into Mercury's formationThe surface has sulfur levels 10 times higher than Earth'sThe MESSENGER orbiter has been circling Mercury since March 2011

[EX Q]: Wenchang, China (CNN) The second launch of China's new-generation Long March-5 carrier rocket failed Sunday -- dealing a blow to the country's ambitious space aspirations. Carrying an experimental communications satellite, China's largest rocket lifted off at 7:23 p.m. local time (7:23 a.m. ET) toward clear skies from the seaside Wenchang space launch center on the southern Chinese island of Hainan. But 40 minutes later, the state-run Xinhua news agency flashed a headline declaring the launch a failure -- without providing any details. Dubbed "Chubby 5" for its huge size -- 5 meters in diameter and 57 meters tall -- the LM-5 rocket is designed to carry up to 25 tons of payload into low orbit, more than doubling the country's previous lift capability.Details of what happened are unknown.Rocket carried communications satellite.
