Vintage Find: 1,000-Year-Old Vineyards Discovered in Spain

Traces of ancient vineyards that date back 1,000 years were discovered in the terraced fields of a medieval village in Spain, according to a new archaeological study. Researchers from the University of the Basque Country found evidence that fields within the medieval settlement of Zaballa were once intensely used to grow grape vines. "Archaeo-botanical studies of seed remains found in the excavations and pollen studies have provided material evidence of the existence of vine cultivation in a relatively early period like the 10th century," study author Juan Antonio QuirĂ³s-Castillo said in a statement. The village of Zaballa was abandoned in the 15th century, largely after local lords operating under a newly created rent-seeking system drove out many of the town's settlers.

New Eruption May Be Brewing at El Hierro Volcano

Two years after a new underwater volcano appeared offshore of El Hierro in the Canary Islands, earthquake swarms and a sudden change in height suggest a new eruption is brewing near the island's villages, officials announced today (Dec. 27). After the announcement, one of the largest temblors ever recorded at the volcanic island, a magnitude-5.1 earthquake, struck offshore of El Hierro at 12:46 p.m. ET (5:46 p.m. local time) today, the National Geographic Institute reported. Before the earthquake struck early this afternoon, the island's volcano monitoring agency, Pelvolca, had raised the volcanic eruption risk for El Hierro to "yellow." This warning means that activity is increasing at the volcano, but no eruption is imminent. Parts of El Hierro have swelled nearly 3 inches (7 centimeters) in the past week, with the growth centered between El Pinar and La Restinga, according to Involcan, the Volcanological Institute of the Canaries.

Technical problem delays space station streaming-video venture

By Irene Klotz CAPE CANAVERAL, Florida (Reuters) - Spacewalking cosmonauts on Friday installed two cameras outside the International Space Station for a Canadian streaming-video business but then retrieved the gear after electrical connections failed, officials said. Station commander Oleg Kotov and flight engineer Sergey Ryazanskiy left the station's Pirs airlock at 8 a.m. EST (1300 GMT) as the complex sailed 260 miles over Australia, mission commentator Rob Navias said during a NASA Television broadcast of the spacewalk. ...

Cosmonauts Hit Snag with HD Cameras in Record-Breaking Spacewalk

Two Russian cosmonauts installed new HD camera eyes on the International Space Station during a record-setting spacewalk Friday (Dec. 27), only to have to return the devices inside due to an unspecified data glitch. Cosmonauts Oleg Kotov and Sergey Ryazanskiy spent just over eight hours — a new endurance record for Russian spacewalks — working outside the space station to install the new Earth-watching cameras for the Canadian company UrtheCast as part of an agreement with Russia's Federal Space Agency. "It appears that we have seen an unsuccessful attempt at bringing those two cameras to life," NASA spokesman Rob Navias said during spacewalk commentary.

Camera glitch triggers marathon Russian spacewalk

Russia launches new Soyuz rocket

Russia successfully launched an upgraded version of its Soviet-design Soyuz rocket on Saturday, the Defence Ministry said, giving a boost to the country's troubled space program. The launch of the Soyuz 2.1v rocket, which features a new engine and digital guidance system, had originally been planned for the beginning of 2012 but was postponed due to an accident during testing which caused engine damage, Interfax reported. The lightweight launch vehicle blasted off Saturday afternoon from Russia's Plesetsk launch pad in the northwest Arkhangelsk region. The Soyuz 2.1v is the latest addition to Russia's Soyuz family of rockets, which has become the world's most frequently used booster since its first launch in 1966.
