Unfortunately earlier in the week Felix Baumgartner had to delay his space jump from 120,000 feet, due to windy weather conditions. However hopefully if the weather allows, he will be re-attempting to jump this Sunday 14th at 8:30am EDT.

Taking him up to 120,000 feet height above the Earth is a special balloon called the Red Bull Stratos, which has been specially created to hold a colossal 30 million cubic foot (843,497 cubic meters) of helium gas.

As you can see in the image above the balloon is absolutely gigantic in size and is the biggest balloon ever made measuring 102.05 m tall approximately 335 feet. Equivalent to a 55 story building, or higher than the Statue of Liberty to put it in perspective.

When Felix Baumgartner makes the jump back to Earth from 120,000 ft up he is expected to travel at around 690 miles per hour or 1,110 kilometers per hour, as he hurtles back to Earth.
