NASA | Exploring the Inner Solar System (Part 6/6)

In the final part of Dr. Garvin’s lecture he continues discussion for the future of exploring Mars with the upcoming Mars Science Lab/Curiosity Rover, the concepts for a future Mars sample-return mission, and his dreams of one day sending humans to Mars. (Show Description) Chief Scientist of NASA’s Goddard Space Flight Center, Dr. Jim Garvin, takes us on a journey to Mercury, Venus, Earth, the moon, near-Earth objects, and Mars. Why does space matter? Why is exploring the inner solar system so crucial? Where will humans and robots venture to next? In this video lecture, filmed July 14, 2010 in NASA Goddard’s HD Science Studio with an audience of summer interns and co-op students, Dr. Garvin discusses NASA’s past, present, and future of discovery on our nearest neighbors in the solar system.

By looking for evidence of water, carbon, and other important building blocks of life in the Mars soil and atmosphere, this suite will help answer one of humankind’s biggest questions about the planet: did it ever support life? SAM was designed and built in an international collaboration between Goddard Space Flight Center, the Jet Propulsion Laboratory, the University of Paris, and Honeybee Robotics.

The water cycle is the movement of water around the Earth in all its forms, from the ocean to the atmosphere, to snow, soil, aquifers, lakes, and streams on land, and ultimately backs to the ocean. This video explains what the water cycle is and how important it is to life on earth.

This unique atom is the basic building block of life, and its compounds form solids, liquids, or gases. Carbon helps form the bodies of living organisms; it dissolves in the ocean; mixes in the atmosphere; and can be stored in the crust of the planet. A carbon atom could spend millions of years moving through this complex cycle. The ocean plays the most critical role in regulating Earths carbon balance, and understanding how the carbon cycle is changing is key to understanding Earths changing climate.

Subscribe to NASA on itunes! phobos.apple.com Or get tweeted by NASA: twitter.com We know climate change can affect us, but does climate change alter something as vast, deep and mysterious as our oceans? For years, scientists have studied the world’s oceans by sending out ships and divers, deploying data-gathering buoys, and by taking aerial measurements from planes. But one of the better ways to understand oceans is to gain an even broader perspective – the view from space. nasa’s Earth observing satellites do more than just take pictures of our planet. High-tech sensors gather data, including ocean surface temperature, surface winds, sea level, circulation, and even marine life. Information the satellites obtain help us understand the complex interactions driving the world’s oceans today – and gain valuable insight into how the impacts of climate change on oceans might affect us on dry land.

In the last two decades, the rate of our world’s warming accelerated. Scientists predict that the globe will continue to warm over the course of the 21st century. Is this warming trend a reason for concern? After all, our world has witnessed extreme warm periods before, such as during the time of the dinosaurs. Earth …
