Russia Soon To View Two Space Transport Projects
Moscow (RIA Novosti) Dec 14, 2007 Russia's rocket and space corporation Energia has developed six projects for new manned spacecraft, two of which will be submitted to Russia's space agency in the near future, a source said Wednesday. "Two of the most attractive projects for spacecraft as part of a reusable manned transport system could be submitted to the Federal Space Agency in the near future," the spokesman said. Russia has been developing the Clipper, a six-man spacecraft similar to the U.S. space shuttle, designed to replace the Soyuz and Progress launch vehicles in making regular flights to the International Space Station and even the Moon and Mars. It is proposed the craft will carry two professional astronauts and up to four passengers, compared to the Soyuz's three-member crews. The projects also envisage innovations such as an orbital transfer vehicle and a cargo container with an increased payload capacity of 12 metric tons, as compared to the current two tons. In December 2006, Anatoly Perminov, the head of the Federal Space Agency, said the agency planned to start construction of the new Clipper in 2012.

Brain Stem Cells Sensitive To Space Radiation
Gainesville FL (SPX) Dec 13, 2007Measures to protect astronauts from health risks caused by space radiation will be important during extended missions to the moon or Mars, say researchers in a paper currently online in Experimental Neurology. Using a mouse model designed to reveal even slight changes in brain cell populations, scientists found radiation appeared to target a type of stem cell in an area of the brain believed to be important for learning and mood control. |
