Convert equation of a circle to polar form

On Sept. 9th, 2011, Arctic sea ice most likely hit its minimum extent for the year. On Sept. 20th, NASA's Cryosphere Program Manager, Tom Wagner, shared his perspectives on the ice with television audiences across the...

Convert a linear equation to polar equation

A look at how the historic DaisyWorld model illustrates earth science concepts, such as albedo and feedback loops. This webshort was produced as an educational tie-in with the Science on a Sphere feature LOOP.

Earth's polar regions: the "canary in the coal mine" of global climate change. The time to learn more is now. Two years of intensive research and education focused on the Earth's poles began March 1, 2007 with the launch of the...

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

NASA’s Operation IceBridge is back in the field, but this time, there’s a twist. Instead of using the P-3 or DC-8 aircraft from previous campaigns, they’ve outfitted a C-130 cargo plane for the trip. Science flights begin this week as...

Arctic sea ice has reached its peak winter extent for the year, and it’s the lowest winter maximum on record. <b<b<br/>r/>r/>

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

With spring right around the corner it is the season for auroras. The beautiful and mysterious auroras are spectacular to watch, but they are actually a manifestation of violent space weather. This weather can create big problems here...

Organic Chemistry Practice Exam 9

For the second straight year, NASA's Operation IceBridge is collaborating with the European Space Agency's CryoVEx program, flying aircraft low over Arctic sea ice while ESA's CryoSat satellite orbits above. In this video, IceBridge...

Where’s it coming from? With global average temperatures rising, it would be natural to assume that total quantities of sea ice would be falling. But it’s not. Scientists have begun to observe sea ice increases around Antarctica, and...

NPP is the prototype of the next generation weather satellites, named JPSS. NPP has five instruments on board and will continue the legacy of existing weather satellites like Terra and Aqua. NPP will deliver critical data not only for...

Earth is currently in a period of warming. Over the last century, Earth's average temperature rose about 1.1 F (0.6C). In the last two decades, the rate of our world's warming accelerated. Scientists predict that the globe will...

NASA's Operation IceBridge has launched its Antarctic 2012 campaign, flying high-priority missions measuring polar ice from a base of operations at the tip of Patagonia on the Strait of Magellan. They have even made a return visit to...

Last year Operation IceBridge flew for the first time out of McMurdo Station in Antarctica, reaching a new slate of exciting science targets. But that means it's now been two years since the mission has flown over critical areas in West...

Having just arrived in Greenland, the first challenge for the Operation IceBridge Arctic 2015 campaign was to survey a broad swath of Arctic sea ice … and along the way, locate and precisely overfly a Norwegian research vessel frozen...

NPP is nearly ready to be launched! This video describes the final steps for this Earth-observing climate and weather satellite before it launches, currently scheduled for the morning of Oct. 28, 2011.<b<b<br/>r/>r/>

This animation shows the seasonal advance and retreat of sea ice over the Arctic from 2005-2006. The false color of the sea ice, derived from the AMSR-E instrument on NASA's Aqua satellite, highlights the fissures in the sea ice by...

How can Greenland's ice sheets still be more than 10,000 feet thick, if carbon dioxide is warming the planet?<b<b<br/>r/>r/>

The Arctic sea ice pack is nearing its annual minimum extent, which is projected to be one of the lowest since satellite observations began.



Using satellite data and airborne observations, NASA researchers are monitoring the...

Consistency counts when collecting scientific data. With global ice inventories in a profound state of change, it’s essential to maintain regular measurements of ice at the poles. NASA’s ICESat satellite amassed a substantial body of...
