Will people travel to Mars on vacation? According to Richard Brason, space travel might become common by the end of this century. Branson founded the Virgin Galactic space program to take people into space. You can make a reservation today for a future trip!
But traveling to Mars is more difficult. It is 35 million miles away! Franklin Chang Diaz, a former NASA scientist, is developing a rocket that will send a shuttle into space at the speed of 55 kilometers per second. The trip from the Earth to Mars will be reduced from 6 to 8 months to 39 day. NASA, the U.S. space agency, announced that someday people may even live on Mars. But before that happens, many questions will have to be answered.
