Today, national agencies like NASA aren't the only ones taking on the challenge of space exploration. Many private companies are developing vehicles to ferry astronauts, private citizens and cargo into space.In 2009, Virgin Galactic unveiled its new spaceplanes--currently undergoing flight-testing.
FLYING TO SPACE
Founded by entrepreneur Richard Branson, private company Virgin Galactic is developing spaceplanes that will one day carry paying citizens into suborbital space--more than 60 miles above Earth--for a brief but unforgettable journey.
TRAINING FOR THE TRIP
If you can afford a flight on SpaceShipTwo, get ready for days of pre-flight training to prepare for some of the intense effects. Several times during the flight, passengers will experience many times the normal force of gravity back on Earth.
