Have you ever heard of the Showdown at Separation Point? In 1878, astronomers, James Watson and Urbain J.J. Le Verrier, disagreed about the existence of a planet, being named Vulcan, between the sun and Mercury. During an eclipse over Wyoming with telescopes and sky maps, they were finally able to discover which astronomer was right. Who do you think won this science showdown?

Do you know that astronauts are not the only living beings who can travel through space? Our human microbes do as well! When human astronauts go into space and return, they bring the microbes inside their bodies with them! Learn what these organisms teach scientists and how they can affect the human body both in space and on Earth.

Have you ever wondered what living in space would be like? Meet the Kellys who are identical twins and both astronauts for NASA. With one brother in space and the other on Earth, they are an experiment to learn how human bodies that share the same DNA are affected by living in space for a long time. What do you think NASA can learn from this twin science study?

Take a ride on a rover with NASA as they explore the planet Mars. Learn how NASA explores Mars for evidence of life especially the existence of water. Scientists believe that life depends on water. Is it possible that Mars had life and why is it so different from Earth? Discover the tools, equipment and methods scientists use to uncover rock, water, and fossils to test as evidence of life.

What should you expect if you want to become one of the first inhabitants of a Martian colony? Humans have never lived on Mars so they will have many challenges to overcome in order to successfully stay there. Learn what the future lives of new Martians will be like and understand the obstacles they will need to overcome in order to build a new Martian society.

Do you know what kinds of food astronauts eat and drink while on a space mission? Learn how NASA prepares, dries and packages different food so it lasts for the journey! Find out the different ways that astronauts cook and eat in space which has zero gravity so it doesn't float away. Discover how astronauts use a very different kind of bathroom toilet and what happens to human waste in space.

Did you hear? Pluto is not considered to be a planet anymore—but don’t worry, astronomists used scientific evidence to prove Pluto's demotion. Learn about the scientific method and how it allows scientists to reevaluate theories as new evidence emerges. What do you think Pluto should be classified as? Planet or Dwarf Planet?

Have you heard of the spidernauts? These two special jumping spiders were sent to space for a special mission—to see how they would adapt to microgravity. Would the spiders still be able to hunt for their food for their survival or would they starve? Learn how this experiment with insects was important to understanding microgravity and its effects on the human body!

Peter was born on the east side of Germany, the side that wasn't free. He watches news programs rather than cartoons, and wears scratchy uniforms instead of blue jeans. His family endures long lines and early curfews. But Peter knows it won't always be this way. Peter and his family have a secret. Late at night in their attic, they are piecing together a hot-air balloon—and a plan. Can Peter and his family fly their way to freedom?

Sixty-six million years ago an asteroid as large as Mt. Everest hit what is now the Yucatan Peninsula at a speed ten times faster than the fastest rifle bullet. Debris from the impact blew into space, re-entered the atmosphere as a swarm of shooting stars that burned the global forests and grasslands, leaving behind a thin global layer containing rock from the asteroid and from Mexico, and smoke from the fires. This layer marks one of the greatest extinctions in Earth history including not just dinosaurs, but also fish, plankton, ammonites, and plants making up about 75% of the known species.
