Giant space sail could take spacecraft to
the stars
Humankind’s first venture beyond the
solar system may begin soon

A future NASA mission could take a spacecraft out of the solar
system.
The interstellar probe would be the biggest, fastest spacecraft
ever.
Using thin reflective sails made of composite materials, it would
span 440 yards -- twice the diameter of the Louisiana
Superdome.
The spacecraft would use sunlight for propulsion and later
missions might use microwave beams or laser beams.
It would move fast -- 58 miles per second, more than 10 times
faster than the Space Shuttle’s orbit speed of 5 miles per second,
or New York to Los Angeles in 43 seconds.
The challenging, unprecedented 15-year journey could begin as
early as 2010.
Team members from the Marshall Space Flight Center and
NASA’s Jet Propulsion Laboratory in Pasadena, Calif. are
working to make space sails a reality.
