Finding The Wreckage of NASA’s Mars Polar Lander Will Lead The Clues What Went Wrong

Start discussionYessi Pratiwi on June 1st, 2008

It was revealed in NewScientist that finding the wreckage might explain why the mission of NASA’s Mars Polar Lander failed in 1999.
Alfred McEwen of the University of Arizona in Tucson, US, said that if they can find the Mars Polar Lander and be convinced they understand what they’re looking at, it might provide some clues […]

The Research of Nose Spray Anthrax Vaccine

Start discussionYessi Pratiwi on May 7th, 2008

In recent years, anthrax has become a top choice as a biological warfare agent, according to the U.S. Department of Defense (DOD), because its spores can easily become airborne.
Early studies show that a new mucosal vaccine against anthrax has the potential to provide military personnel with more effective and efficient protection against a “popular” bioweapon. […]

ScienceDaily reported, a team of Japanese astronomers has discovered that our galaxy’items’ => 4,s central black hole let loose a powerful flare three centuries ago by using NASA, Japanese, and European X-ray satellites.
This finding helps resolve a long-standing mystery: why is the Milky Way’items’ => 4,s black hole so quiescent? Black Hole is an extremely […]

Great Advantages of Hybrid Car

One replyYessi Pratiwi on April 4th, 2008

Hybrid cars are presently considered as very beneficial to the preservation of the environment. A hybrid car combines an electric motor and gasoline engine to provide sufficient power to the vehicle with least fuel usage and fewer emissions. They are also far more fuel-efficient than purely gas-powered cars, and far more practical for everyday […]
