Ariane 5 lifts off
BBC News reports the ESA's Ariane 5 rocket has lifted off from its launch facility in French Guiana. The rocket left the launch pad at 2103 GMT, or 2:03 p.m. Pacific time.
Lagrange 5 is a waypoint to internet destinations about space and spaceflight. L5 evolved from a series of hyperlink sites hosted from GeoCities since 1999.
Lagrange points are five locations in space around two gravitational bodies (such as the earth and the moon), where future spacecraft will be able to achieve "fixed" orbits. The most stable of these points are L4 and L5. Each of these locations are equidistant from the earth and the moon, so that the forces between the objects are balanced.
Lagrange points were discovered by Italian-French mathemetician Joseph Louis Lagrange (1736-1813). Also called libration points, they are considered ideal staging areas for future exploration within the solar system.
