NASA Science website is an awesome resource

To show how useful this site can be, here are links to pages I found as I dug deeper into just one of the many areas on the NASA Science website.

Science for different levels of learning

The NASA Science website provides learning opportunities for four learning groups.

Earth, sun, planets, and astrophysics

The NASA Science website is divided into these parts.

Ten year birthday for Cassini Huygens

The Cassini Huygens mission to Saturn just passed its ten year mark. It blasted off from Earth on Oct 15, 1997. I hooked up my computer to the internet a month later, and have been enjoying photos from it ever since. Last year for Paul McCartney's 64th birthday, sixty-four images from Cassini were put together into a poster and a movie.

Jupiter, Saturn, and its moons

Cassini flew by Jupiter on the way to Saturn . Cassini approached Saturn in mid-2004. One of my favorite photos is titled, The Dragon Storm. You can click through all of the Cassini photos by starting on this Cassini Imaging Diary page.

Huygens lands on Titan

The term "Huygens" refers to a probe attached to the Cassini craft. On Christmas Day, 2004 it separated itself and landed on Saturn's moon, Titan (click here to access videos and photos).

The Cassini spacecraft currently in orbit around Saturn is sending back incredible images of the ringed planet and its moons. Its next flyby of Saturn’s moon Titan is tomorrow, at around 3:30 am Central Time. The flyby tomorrow will be used to determine if Titan has a subsurface ocean.

Like most other NASA missions, there is a lot of material to whet your appetite for space information. There are video updates from the Jet Propulsion Laboratory (JPL), image galleries, and even an opportunity to vote on your favoriate image from the Cassini mission.

The Cassini spacecraft is a joint project between NASA/JPL, the European Space Agency (ESA) and the Italian Space Agency (ASI). Cassini was launched on October 15, 1997 and has been in orbit around Saturn since July 2004.

Saturn's moon Titan is the only satellite (moon) in our solar system that has a dense atmosphere. Nitrogen is the main component of this atmosphere and methane the second most important. The Cassini spacecraft photographed Titan as it passed by on October 26, 2004. Later analyses of the images revealed a cryovolcano that spews ice instead of lava. This finding is reported by Christopher Sotin and associates at Universite de Nantes and the Universite de Paris-Sud in France and other institutions in Germany, Italy, and the USA (Arizona, California, Colorado, New York, Washington). This giant ice volcano may also release methane into the atmosphere; however, the images show that a widespread methane ocean does not exist. Because Titan's atmosphere is similar to that of Earth, scientists are studying Titan for clues to the origin of life.
