At sunrise Monday, Endeavour will depart Kennedy Space Center for a museum in California, with a two-day stopover in Houston, home to Mission Control and the astronauts who flew aboard the replacement for the lost shuttle Challenger.

Antarctica's Ross Sea is often described as the most isolated and pristine ocean on Earth, a place where seals and penguins still rule the waves and humans are about as far away as they could be. But even there it has proven difficult, and maybe impossible, for nations to agree on how strongly to protect the environment.

The United States and New Zealand have spent two years trying to agree on an Alaska-sized marine sanctuary where fishing would be banned and scientists could study climate change. U.S. Secretary of State Hillary Rodham Clinton took a strong interest in the outcome, regularly prodding diplomats, and New Zealand recently sent a delegation to Washington to hash out a tentative deal.

The Mars rover Curiosity is preparing to roll again after it completes its health checkups this week, project managers said Wednesday.

The head of ESA's human spaceflight division says some European astronauts are already learning Chinese in preparation for joint missions.

Scientists have discovered well-preserved frozen woolly mammoth fragments deep in Siberia that may contain living cells, edging a tad closer to the "Jurassic Park" possibility of cloning a prehistoric animal, the mission's organizer said Tuesday.

Russia's North-Eastern Federal University said an international team of researchers had discovered mammoth hair, soft tissues and bone marrow some 328 feet (100 meters) underground during a summer expedition in the northeastern province of Yakutia.

Less than a year after going public, the digital production company founded by director James Cameron has filed for Chapter 11 bankruptcy protection and agreed to sell the core of its business to a private investment firm for $15 million.

Digital Domain Media Group Inc., best known for its work on Cameron's "Titanic," has produced visual effects for more than 90 movies, including "Pirates of the Caribbean: At World's End" and the "Transformers" series. And in April, its Tupac Shakur hologram made a splash when it took the stage at the Coachella Valley Music and Arts Festival and appeared to perform alongside Snoop Dogg.

While its rivals covered the solemn commemoration of the first plane striking the World Trade Center on Tuesday, NBC's "Today" show aired Kardashian family matriarch Kris Jenner talking about her breast augmentation.
