Asteroid Headed Towards Earth (03:50)
In October 2008, an asteroid appears to be headed towards Earth. Soon, it is obvious that it is headed straight towards the Nubian Desert. It rips into Earth's atmosphere with the energy of 1,000 tons of TNT. It disintegrates before impact.
Meteorite Hunt (03:15)
Scientists hunt for meteorites left over from the 2008 asteroid. They recover 280 meteorite samples in the Nubian desert.
Rock from the Asteroid Belt (03:02)
Scientists believe meteorite fragments from a 2008 asteroid came from a larger rock from the asteroid belt, a region between Jupiter and Mars
Meteorites Strike Earth (02:03)
When asteroids enter Earth's atmosphere, they become meteors. Over the past century, meteorites have struck homes, vehicles, and people. There is physical evidence of huge impacts by space debris.
Earth Development: Cosmic Violence (01:39)
Over a period that lasted between 20 and 200 million years, Earth's surface was battered by a storm of impactors that beat it to a pulp. Today, 170 impact craters evidence this era called the Late Heavy Bombardment" of planet Earth.
Proof of Earth's Tumultuous Past (02:12)
Evidence on the moon reveals Earth's tumultuous past because it was created at the same time as Earth. Without plate tectonics, the moon's surface still holds the evident of what must have happened to the developing Earth.
Impact Craters Below the Surface (03:24)
Scientific experiments reveal what impact craters might look like beneath the surface of a moon or planet. Impact experiments at the vertical gun range shed light on the large-scale destruction caused by the asteroids that have fallen from space.
Space Impactors and Evolution of Life on Earth (01:48)
Space impacts have affected the evolution of life on Earth. About 65 millions years ago, an asteroid the size of Mt. Everest struck Earth. It created a 100-mile-wide crater underground that was finally discovered in the 1980s.
Cosmic Event and Extinction of Ice Age Pleistocene Mammals (05:19)
What happened on Earth 13,000 years ago to cause a sudden climate change and the extinction of Pleistocene mammals? Evidence of charred earth carbon spherals, and shocked diamonds suggest a cosmic impact that caused climate change.
Fireball from the Sky (03:43)
On June 30, 1908, a ball of fire exploded about 6 miles above the ground in the Tunguska region in Russia. The blast released 15 megatons of energy. A similar event may have contributed to the near extinction of the North American mega-animals.
Meteorite Samples (02:44)
Most meteorites are found in arid desert regions and cold deserts like Antarctica--though they fall everywhere with equal probability. Meteorites come mostly from the asteroid belt. Meteorites provide valuable information about the developing Earth.
Meteorites and Life on Earth (04:04)
Meteorites have played an important role in life on Earth. They may have once supplied the necessary components for life. Could a space rock deliver harmful elements to Earth, such as lethal bacteria or viruses?
Space Age Debris (05:50)
In 2003, space shuttle Columbia disintegrated during reentry to Earth's atmosphere, scattering debris over 3 states. Space is littered with debris from spacecraft, satellites, and more. Fifty-four hundred tons of space junk has already landed on Earth.
