The International Space Station

The International Space Station is an orbiting Laboratory and construction site that synthesizes the scientific expertise of 16 nations to maintain a permanent human in space.while floating some 240 miles (390 kilometers) above Eart's surface, the space station has hosted a rotating international crew since november 2000. astronauts and supplies are ferried by the U.S.Space shuttles and the Russians soyuz and progress spacecraft.Astronauts who reach the facility aboard one of these mission typically live and work in orbit for about six months. simply by spending time in orbit,astronauts reveal much more about how humans can live and work in space.Crews have learned the difficulties of diet,in a world in which their sense of taste is decreased, and of getting a good night sleep while secured to a non-floating objects. but the crew is also occupied with a full suite of scientific experiments,the ongoing improvement and construction of the station, and a rigorous regime of physical training.Astronauts must exercise for two hours each day to counteract the detrimental effects of low gravity on the body's skeleton and circulatory system.

Robot to create competition for uddharakajera pentaganera

the robot to create a competition organized by the inclement uddharakaja pentaganera advanced research laboratory.The main objective, to reduce any risk to the management of disasters, as well as faster time uddharaja management.In this contest, the advanced research laboratoru in pentagon, competition participants will be able to protect human life and foul of modern technology to create the next generation robot.And it will be easier robatake management.

Nasa and Japan Released improved Topographic map of EarthPANSADENA

The map , known as a global digital elevation model , was created from images collected by the japanese Advanced Space borne Thermal Emission Reflection Radiometer , or ASTER, instrument aboard Terra.So-called stereo-pair images are produced by merging two slightly offset two-dimensional images to create the three-dimensional effect of depth.The first version of the map was released by NASA and Japans Ministry of Economy,Trade and Industry (METI) in june 2009.The aster global digital elevation model was already the most complete , consistent global topographic map in the world, said woody Turner, ASTER program scientist at NASA Headquarters in Washington.with these en

Cold Dark Matter Cusps

the presence of a cusp in the centers of CDM halos is one of the earliest and strongest result derived from cosmological N-body simulations.Dubinski and Carlberg [14] were among the first to investigate the density profiles of CDM halos and found that the inner parts of these simulated halos could be characterized by power law slope.they did not rule out the existence of central cores but noted that these would have to be smaller than resolution of their simulations (~1.4kpc).Subsequent simulation, at higher and higher resolution, made the presence of cores in simulated CDM halos, derived assuming many different sets of cosmological
