Space: The Ultimate View (01:52)
The edge of space is 120 miles above sea level. Some predict it is the realm of ultimate, extreme sport. Thrill seekers will engage in spacediving--skydiving from space. Earth orbit is a window to the universe.
Environment of Earth Orbit (05:36)
Cosmic threats exist beyond Earth's orbit. About 1% of the time, a space exploration mission ends in disaster, and there is no evacuation plan for escape from a space capsule. A very special space suit for space divers is under construction.
Space Tourism (04:51)
Space Adventurers, Ltd. is currently the only private space company. Started ten years ago, the company's first private customer was Dennis Tito, a California-based multi-millionaire.
Earth's Orbits (05:47)
Low Earth orbit is like a busy city. Some of the residents include the Hubble telescope and the space station. In medium Earth orbit, global positioning and communications satellites are in orbit. In high Earth orbit 2000 satellites reside.
What Is in Earth's Orbit? (06:03)
Objects are held in orbit by Earth's gravity, and they can stay in space as long as they have enough velocity to resist Earth's gravity. Fifty years' accumulation of space junk orbits the Earth, posing danger for space satellites and for humans on Earth.
Space Debris (02:37)
In 2007, approximately 20,000 pieces of space debris were caught in Earth's orbit. China caused two satellites to collide in orbit. This created a massive amount of space debris. Space debris is a hazard for spacecraft and equipment.
Space Junk Lands on Earth (03:30)
No matter what their size, objects are always in danger of being pulled out of orbit by orbital decay. Some of them survive re-entry and fall to Earth. In the last 40 years, 17,000 pieces of space debris have landed on Earth.
Emerging Industries for Earth Orbit (05:26)
Memorial space flights launch cremated remains into low Earth orbit. Skylab, Mir, and the International Space Station have all created an arena for long-term habitation and experiments in space. Private companies begin to do the same.
Inclinations of Earth's Orbits (02:38)
Satellites are launched into different orbit inclinations, such as the equatorial and polar inclinations, or tilt. Geosynchronous satellites are positioned far away from Earth so that entire continents are within their view.
Private Citizens in Space (02:12)
Bigelow Aerospace in Nevada manufactures and launches inflatable pods that can be used as workplaces, labs, hotels, and more. Their goal is to support private citizens in space for industry or tourism.
Future Space Concepts (02:00)
Many concepts for space have been envisioned by people with dreams and imaginations. They include the space elevator, space "fountain," space mining, and more. Earth orbit offers sustainable power through solar collectors.
