Russian Alien Spaceship Claims Raise Eyebrows, Skepticism - Space.com The Russian research team is called the Tunguska Space Phenomenon foundation and is led by Yuri Labvin. He said in late July that an expedition to the scene would seek evidence that aliens were involved. "We intend to uncover evidences that will prove the fact that it was not a meteorite that rammed the Earth, but a UFO," Labvin was quoted by the Russian newspaper Pravda on July 29.  
Image of Mars, PA Stem cell study's NASA link - BBC  Left:  The technology will be tested in a mission to Mars in 2008.   UK tissue engineering experts are teaming up with Nasa on a series of space experiments which could boost stem cell research - and protect astronauts from radiation. They will use the zero gravity of space to speed up the growth of new tissue from stem cells, potentially easing future organ donor shortages. The Kingston University team hope the project will uncover better ways to protect astronauts from cosmic rays. The research is in preparation for US manned missions to Mars in 2020.

NASA Develops Robust AI For Planetary Rovers - SpaceDaily  NASA is planning to add a strong dose of artificial intelligence (AI) to planetary rovers to make them much more self-reliant, capable of making basic decisions during a mission. Scientists at NASA Ames Research Center, in the heart of California's Silicon Valley, are developing very complex AI software that enables a higher level of robotic intelligence. "It takes about three days for a MER rover to visualize a target, get to the target and do some contact science," said Rajan. "Part of the problem is we are not closing the loop on board the rover. Signals from the rover have to go to Earth for a human with his/her cognitive capacity to deliberate on the information in the signal and make a decision.
