50 Years in Space Humans have always looked up at the sky. They used astronomy to track time, orient their cities, decide when to plant their crops, and even based their religious practices on their celestial world. But there was much more to learn. Click on image to watch video. |

Looking at Hurricanes Hurricanes are the most powerful accumulations of energy on Earth. Nothing else even comes close. They are fearsome tropical storms that spring to life roughly the same time every year, churning up oceans around the world and shredding nerves of residents living along coastal zones.

Cryosphere In a little more than seven minutes, NASA's "Tour Of The Cryosphere: Earth's Frozen Assets" leads viewers across the icy reaches of Antarctica, the drifting expanse of polar sea ice, the shrinking cap around the North Pole, and more. The tour conveys the interconnectedness of the cryosphere and the scientific importance of continued collection of this kind of data. Click on image to watch video.

Thermal Vacuum Testing Thermal vacuum testing is the last major phase of the rigorous environmental testing that a spacecraft undergoes. During this phase, the spacecraft is exposed to alternate cycles of extreme heat and cold simulating the harsh environment of space. Click on image to watch video.

An Inside Look: The EOC Spacecraft subsystems and science instruments must be scheduled, controlled, and monitored daily. These operations are performed primarily at the EOS Operations Center (EOC), located at NASA's Goddard Spaceflight Center in Greenbelt, Maryland. Click on image to watch video. |

Stereo Ever wonder why two spacecraft are needed to study the Sun or how you build them to operate in the extreme conditions they'll experience in space? How do you launch two spacecraft on one rocket? This 6-minute video, "Solar News Network: NASA Gets a Double Dose of the Sun," helps answer these questions. Click on image to watch video. |
