Following is a summary of current science news briefs. NASA bids adieu to Opportunity, the Mars rover that kept going and going

Opportunity, a remarkably durable NASA rover designed to roll along the surface of Mars for three months, has stopped communicating with Earth after 15 years of service, officials said on Wednesday, ending a mission that astounded the U.S. space agency. Engineers lost contact with the solar-powered vehicle on June 10 during a dust storm that encircled Mars. Since then, NASA officials made numerous attempts to reach the six-wheeled rover, which is about the size of a golf cart. Tanzanian 'beast' sheds light on gigantic dinosaur group

A relatively complete skeleton of a long-necked, long-tailed plant-eater excavated from a rocky cliff above a Tanzanian river is providing insight into the early evolution of a dinosaur group that later included Earth's largest-ever land animals. Scientists on Wednesday announced the discovery of fossils of a dinosaur called Mnyamawamtuka moyowamkia that measured roughly 26 feet (8 meters) long, weighed about one ton, lived between 110 and 100 million years ago and was an early and comparatively small member of the group called titanosaurs.
