Gravitational corridors could help spacecraft ply the solar system like ships borne on ocean currents, it has been disclosed by scientists investigating space travel. Click on the image to read about this
Scientists in the United States are trying to map the twisting ''tubes'' so they can be used to cut the cost of journeys in space.
Each one acts like a gravitational Gulf Stream, created from the complex interplay of attractive forces between planets and moons..............
Mars today is a world of cold and lonely deserts, apparently without life of any kind, at least on the surface. Worse still, it looks like Mars has been cold and dry for billions of years, with an atmosphere so thin, any liquid water on the surface quickly boils away while the sun's ultraviolet radiation scorches the ground.
But there is evidence of a warmer and wetter past..........
Montana State University scientists are involved in a new space mission to figure out how energy is transferred through the sun's atmosphere.
As a partner on the IRIS team headed by Lockheed Martin, MSU will receive about $3 million to design an optical system for a telescope that could be launched on a NASA rocket in 2012, said solar physicist Charles Kankelborg. If Lockheed Martin agrees, MSU could receive another $2 million for an associated project involving MSU students.
