Robotic probe to awaken for comet rendezvous, landing

After a 10-year journey, Europe's Rosetta spacecraft is due to end its hibernation on Monday and prepare for an unprecedented mission to orbit a comet and dispatch a lander to the surface. Rosetta's on-board alarm clock is due to go off at 5 a.m. EST (1000 GMT), but it will take the spacecraft about seven hours to warm up its star tracking navigation gear, fire up rocket thrusters to slow its spin, turn on its transmitter and beam a message back to Earth, the European Space Agency said in a status report posted on its website. Ground control teams hope to have confirmation of Rosetta's resuscitation by 1:30 p.m. EST (1830 GMT), the European Space Agency said. It is due to reach a 2.4-mile diameter comet called 67P/Churyumov-Gerasimenko in August.

Comet-Chasing Rosetta Spacecraft Wakes from Deep Sleep Monday: Watch It Live

After more than two years in a deep sleep, the European Space Agency's Rosetta spacecraft is due to awake from its "hibernation" mode at 5 a.m. EST (1000 GMT) on Monday to gear up for an August arrival at its comet target. To mark the occasion, ESA officials will celebrate with a special day-long series of press briefings from the European Space Operations Center in Darmstadt, Germany. The Rosetta spacecraft launched in 2004 on a decade-long journey to the Comet 67P/Churyumov-Gerasimenko. But in mid-2011, Rosetta entered a 31-month "hibernation" as it sailed out toward the orbit of Jupiter — where the available sunlight was too low to power all of its systems.

Rosetta Spacecraft Waking Up for Final Leg of Comet Journey

Rosetta, the first spacecraft built to orbit a comet and land a probe on these icy nomads, is now waking up after more than two years of slumber, and videos filmed as part of an international competition will help greet the spacecraft after it awakens. By analyzing the composition of the comet, the European Space Agency's Rosetta spacecraft will help scientists learn more about the role comets have played in the evolution of the solar system and life on Earth.

The mission's final destination is the mysterious Comet 67P/Churyumov–Gerasimenko, which Rosetta is scheduled to reach in August.

For NASA, 2014 Brings a Big Year for Commercial Spaceflight (Video)

Four private companies working to build commercial spaceships to launch NASA astronauts into space are gearing up for a big year in 2014, space agency officials say. This year, private spaceflight companies Blue Origin, Sierra Nevada Corp., Boeing Space Exploration and SpaceX — which are all NASA partners the space agency's commercial crew program — will continue to perform tests and reviews for their respective space systems. NASA officials are planning on announcing one or two more Commercial Crew Transportation Capability contracts by August that would lead to commercial systems flying astronauts to the International Space Station.

The 5 Places Millennials Want to Work Most

"What are your plans after graduation?" It's a question that high school and college students are forced to answer ad nauseam to every academic adviser and older relative. If students don't have a post-grad plan yet, the very mention of this question can induce fear and panic. Since 2008, the National Society of High School Scholars (NSHSS), a nationwide organization of student academic scholars and young professionals, has released an annual survey highlighting the fields, companies and environments in which its members hope to work. James Lewis, president and co-founder of the NSHSS, said that businesses that want to attract, hire and retain top young, diverse talent should be paying attention to the career goals of this up-and-coming generation of workers.

Too Many Jobs? When Job Hopping Hurts Your Resume

Paul McDonald, senior executive director at Robert Half, said that because the job market has been unpredictable in recent years, most employers understand that job candidates may have had short stints in some positions. "Too much voluntary job hopping can be a red flag." [8 Words That Will Land Your Resume in the Trash] Robert Half offers questions employees should ask themselves when determining if they should stay at their current job or look for a new one: Have you looked within your current company?

Money Isn't The Only Thing Making Bosses Happy

A study by the Pew Research Center revealed that in addition to earning higher salaries, America's bosses are more satisfied with their family life, jobs and overall financial situation than nonmanagerial employees are. Additionally, top managers who have children are less likely than other working parents to say parenthood has been an obstacle to job advancement. Top managers are also significantly more likely than those who work for them to think of their job as a career and less likely to say it's just a job. The study showed that four in 10 top managers said they are very satisfied with their financial situation, compared with just 28 percent of nonmanagerial workers.

Scientists hope comet-chaser spacecraft wakes up

BERLIN (AP) — Scientists at the European Space Agency are expecting an important call.

Panda Cub Bao Bao Makes Public Debut at National Zoo

Visitors to the Smithsonian's National Zoo in Washington, D.C., can finally get a glimpse of the panda cub Bao Bao. Bao Bao, whose name means "precious" or "treasure" in Mandarin, was born on Aug. 23, 2013 to the 15-year-old panda Mei Xiang. The cub is one of more than 300 pandas living in captivity worldwide, most of them in China. The only other zoo in the United States that currently has newborn pandas on exhibit is Zoo Atlanta, where female twins were born in July.

Sunshine May Lower Your Blood Pressure

While too much sun exposure may bring on skin cancer, researchers have found evidence getting some rays could protect against high blood pressure, a condition known as the silent killer. Researchers in the United Kingdom gave healthy study volunteers a dose of Ultraviolent-A (UVA) radiation in a lab, correspondingto what they would receive while under the sun for about 30 minutes during summer in Southern Europe. In response, the participants' blood vessels dilated, and their blood pressure decreased, the researchers report. "But sunlight and the potential contribution the skin may make has never been on the radar," said study researcher Martin Feelisch, professor of experimental medicine and integrative biology at the University of Southampton.

Melatonin Linked to Prostate Cancer Risk

Men with higher levels of the sleep hormone melatonin may be less likely to develop prostate cancer, a new study suggests. The research also revealed that men who had higher levels of melatonin in their urine had a 75 percent decreased risk of advanced prostate cancer, compared with men with lower melatonin levels. "It's notable that we found a stronger association between melatonin levels and more advanced prostate cancer," said study researcher Sarah Markt, a doctoral candidate in the department of epidemiology at the Harvard School of Public Health in Boston.
