Fastest Glacier in Greenland Doubles Speed
12.1.04 -- Scientists who study Earth's ice and the flow of glaciers have been surprised to find that the world's fastest glacier in Greenland doubled its speed between 1997 and 2003.

Lunar Reconnaissance Orbiter
10.26.04 -- NASA plans to launch in 2008 the Lunar Reconnaissance Orbiter. The mission will map the lunar surface, search for surface ice deposits and investigate space radiation. NASA's mission to extend human exploration into the solar system embraces the International Polar Year as we study the poles of our own moon.

Arctic Sea Ice Decline Continues Between 2002-2004
10.6.04 -- Every September researchers produce a map of Arctic sea ice and compare that year's measurements to the long-term average. The ice extent was 13.4 percent less than average in September 2004, 12 percent below average in 2003, and 15 percent below average in 2002.

Larsen-B Ice Shelf Collapse, 2002
9.21.04 -- In 2002, after 12,000 years of stability, the Larsen-B Ice shelf collapsed in just five weeks. The ice shelves that surround half of the Antarctic continent slow the relentless march of ice streams and glaciers to the ocean.

GRACE and Ice
2.24.04 -- As NASA's Gravity Recovery and Climate Experiment (GRACE) twin satellites travel over areas of snow and ice sheets such as Greenland and Antarctica, changes in mass are recorded. This information, along with measurements from the ground and other satellites will enable scientists to determine if these areas are growing or shrinking.

Phoenix: A Mission to the Martian Arctic
1.1.04 -- In 2008, NASA's Phoenix mission will land at the icy northern pole of Mars. Using a robotic arm, Phoenix will dig trenches and use its on-board laboratory to analyze the samples. Phoenix will reveal a clearer picture of the history of the Martian arctic.
