Documenting NASA's Phoenix mission to search for water on Mars and determine whether the planet may have sustained life in the past.
Examining Earth's complex atmosphere. Included: how it is necessary for life on the surface; a man who braved its dangerous upper reaches and survived.
One day technological advances may allow us to relocate to other planets. Journey through the solar system to discover what we would find and how these alien planets compare with our own.
Is it possible to stop a hurricane? Some scientists think it is.We have chosen seven scientists and inventors who will pitch their theories, and we observe a real mega-storm bearing down on the Gulf Coast. Intercutting between hurricane footage, experiments, small-scale trials and computer animation, the seven innovators present how their plans would stop, stall, weaken or divert a future hurricane before it can make landfall on a major coastal city.
Why do some buildings collapse during earthquakes? Meet the man who may have made a breakthrough in predicting earthquakes and hear the compelling stories from survivors and rescuers.
Local scientists try to ascertain the cause of a series of worsening quakes in Reno, Nevada. Is the city on the verge of a major disaster?
Imagine a world where sea levels have risen by 20 feet. Cities flood and coastal regions disappear. Travel to Greenland where scientists are investigating if this nightmare could become a reality.
Is Mount Vesuvius set for another enormous eruption? Explore the alarming evidence helping to forecast the mighty volcano's future activity.
Scientists believe that our universe started with a colossal explosion called the Big Bang. That powerful blast created all the matter and energy in the universe and laid the groundwork for every explosion since.
How did life begin? its one of the most fundamental and difficult questions that has challenged us for ages. Our planet is teaming with life, from the highest mountain to the deepest ocean; life is everywhere. But what was the firing pistol that started the evolutionary race? How did material go from non-living to alive?
In 250 million years, Earth may be a single supercontinent. Scientists believe a future single landmass world could destroy all life.
America once was ravaged by some of the largest, most destructive hurricanes ever. Are these mega-storms poised to return, targeting the heavily populated eastern coastline?
Many serious scientists believe that time travel is inevitable, but travelling into the past raises difficult issues. Could we change history?
Scientists are uncovering ways in which the sun dictates our climate. Could the sun be the key to saving the Earth from global warming? Plus, could solar wind be more important than we ever realised?
The Hubble Space Telescope can see to the far reaching corners of the galaxy and is one of the most important scientific instruments ever built, but can it unlock the secrets of the universe?
On a single day on a single street, with the DNA of just a couple of hundred random people, National Geographic Channel sets out to trace the ancestral footsteps of all humanity. Narrated by Kevin Bacon, The Human Family Tree travels to one of the most diverse corners of the world -- Queens, N.Y. -- to demonstrate how we all share common ancestors who embarked on very different journeys. Regardless of race, nationality or religion, all of us can trace our ancient origin back to the cradle of humanity, East Africa. What did our collective journey look like, and where did it take your specific ancestors? At what point in our past did we first cross paths with the supposed strangers living in our neighborhood? Now, in The Human Family Tree, the people of this quintessential American melting pot find out that their connections go much deeper than a common ZIP code.
More humans have traveled to the moon that have been to the ocean's floor. Virtually unexplored, the trenches of the oceans could swallow Mt. Everest. Despite the crushing pressure, Earth's final frontier holds great potential for meeting the planet's energy needs and perhaps to cure diseases.
The story of mankind's first open ocean crossing to Australia. Experts answer mysteries surrounding the journey, including how it was achieved.
The Genographic Project aims to sample the DNA of more than 100,000 indigenous people from around the world, with the ultimate goal of charting new knowledge about the migratory history of the human species. DNA will be used for a five-year research partnership led by Dr. Spencer Wells, renowned international scientists, and IBM researchers.
Who really discovered America?
They were sent to Mars on a 90-day mission, but almost five years later the rovers Spirit and Opportunity have traveled farther, seen more, and survived longer than anyone imagined possible, earning a place among the most prolific explorers in history.
