Three cavenauts during ESAs 2013 underground astronaut training

course CAVES. CAVES stands for Cooperative Adventure for Valuing and

Exercising human behaviour and performance Skills. The two-week

course prepares astronauts to work safely and effectively in multicultural

teams in an environment where safety is critical in caves. (Credit: ESA-

Oct. 4, 2013 Usually, ESA sends astronauts to outer space, but

last week six astronauts from around the world spent six days

underground to get a taste of working together in extreme

conditions. ESA's caves training in Sardinia, Italy ended with a

debriefing, with the astronauts claiming, "This is some of the best,

arguably the best, spaceflight 'analogue' training we have received."

Veteran and rookie astronauts worked together and learned from each

other on how to conduct science and survive in isolation while living

disconnected from aErth's normal day and night cycle -- just like on the

International Space Station. CAVES is not a simulation but a real

expedition and the only expedition training on offer to involve

astronauts from all Space Station partners.

Oct. 9, 2013 A mystery that has stumped scientists for decades might be one step closer to solution after

ESA tracking stations carefully record signals from NASA's Juno spacecraft as it swings by Earth today.NASA's deep-space probe will zip past to within 561 km at 19:21 GMT as it picks up a gravitational speedboost to help it reach Jupiter in 2016. During the high-speed event, radio signals from the 2870 kg Juno will

be carefully recorded by ESA tracking stations in Argentina and Australia. Engineers hope that the newmeasurements will unravel the decades-old 'flyby anomaly' -- an unexplained variation in spacecraft speeds

detected during some swingbys. "We detected the flyby anomaly during Rosetta's first Earth visit in March2005," says Trevor Morley, flight dynamics expert at ESA's ESOC operations centre in Darmstadt, Germany.

"Frustratingly, no anomaly was seen during Rosetta's subsequent Earth flybys in 2007 and 2011. This is a real

cosmic mystery that no one has yet figured out."

Knowledge exists potentially in the human soul like the seed in the soil; by

learning thepotential becomes actual. IMAM AL-GHAZALI
