Space Science - Everyday Astronauts
Part of the Series: Show Me Science Series - Advanced
With the retirement of NASA's space shuttle fleet in 2011, the role of getting people, satellites and other instruments into space falls to private companies. As of June 2011, there have been only 523 people to reach the 100 kilometer mark (considered human spaceflight), and only 24 have traveled beyond…
Part II: Physics in Space - Orbital Motion and Re-entry
Part of the Series: Physics of Spaceflight Series
Concepts Covered:
  • Newton's Laws of Motion
  • Circular Motion
  • Rotational Dynamics
  • Heat
  • Conservation of Energy
This program focuses on the physics of orbital motion and re-entry into the earth's atmosphere. The program discusses the dynamics of orbital motion and the apparent weightlessness experienced while in orbit. Kepler's 3 laws…
Our Fascinating Universe
Embark on a journey to distant worlds in this fascinating presentation that attempts to answer questions on the origins and meaning of the universe.
Order Out of Chaos
Part of the Series: Seven Wonders of the Solar System
In Order Out of Chaos, Brian reveals how beauty and order in earth's cosmic backyard was formed from nothing more than a chaotic cloud of gas. Chasing tornados in Oklahoma, he explains how the same physics that creates these spinning storms shaped the young solar system. Out of this celestial…
Man on Mars - Mission to the Red Planet
Part of the Series: Horizon
Horizon goes behind the scenes at Nasa to discover how it is preparing for its most ambitious and daring mission: to land men - and possibly women - on the surface of Mars. It's over 40 years since Neil Armstrong made the first human footprint on the moon. But getting…
Alien Planets Revealed
Part of the Series: NOVA
It's a golden age for planet hunters: NASA's Kepler mission has identified more than 3,500 potential planets orbiting stars beyond our Sun. Some of them, like a planet called Kepler-22b, might even be able to harbor life. How did we come upon this distant planet? Combining startling animation with input…
Mission to Mars
Part of the Series: Horizon
Due to land in August 2012, NASA's Curiosity Rover is intended to answer the big question about Mars - is it a suitable environment for life? The biggest and most powerful machine ever sent to Mars, Curiosity is a mobile lab packed with diverse scientific equipment and the information it…
The Stellar Atom-Building Machine
Episode 5 of The Nature of Matter
Where did atoms come from? Trace the story of nucleosynthesis--the formation of complex nuclei and atoms. Cover this process from the big bang, which filled the universe with hydrogen and helium, to the events inside stars that produced practically all of the heavier elements.
The Cyclic Universe with Professor Sir Roger Penrose of the University of Oxford
Sir Roger Penrose, Emeritus Rouse Ball Professor of Mathematics at the Mathematical Institute of the University of Oxford, is convinced that there is one fundamental problem that is consistently being overlooked in modern cosmological approaches: why did our universe begin in such a particular state of extremely low entropy? His…
Cosmic Antigravity—Inflation and Dark Energy
In this episode, investigate cosmic antigravity, starting with cosmic inflation, a phenomenon that exponentially increased the size of the universe during the big bang. Then, learn why dark matter cannot be made of ordinary protons and neutrons, and explore the recent discovery that the expansion of the universe is accelerating,…
