Some anticipated the 'collision of the century': the vast, drifting B15-A iceberg was apparently on collision course with the floating pier of ice known as the Drygalski ice tongue. Whatever actually happens from here, Envisat's radar vision will pierce through Antarctic clouds to give researchers a ringside seat.

China's spectacular economic growth during the last decade has brought many benefits ? and some challenges. Global atmospheric mapping of nitrogen dioxide pollution performed by ERS-2's GOME and Envisat's SCIAMACHY reveals the world's largest amount of NO2 hanging above Beijing and northeast China, as reported in Nature this week.
A week after the tsunami that hit Asia on 26 December the death toll is still rising. Nearly 140 000 people are confirmed dead, more than 1.8 million people need food aid and an estimated five million are homeless.

There is a desert in the heart of the South Pacific. Surrounding Easter Island is the purest and bluest seawater on Earth, almost empty of the microscopic phytoplankton at the base of the marine food web. French vessel L'Atalante recently completed a research cruise through this region, its day-to-day route guided by ocean colour satellites.

This ultra high-resolution sea surface temperature map of the Mediterranean could only have been made with satellites. Any equivalent ground-based map would need almost a million and a half thermometers placed into the water simultaneously, one for every two square kilometres of sea.

It is hard to overstate the scale of the humanitarian emergency unfolding in Sudan's strife-torn Darfur region: by current estimates there are 1.45 million people displaced from their homes across an area the size of France. However, images from space are assisting aid workers as they cope with the crisis.

Based on 18 months of Envisat observations, this high-resolution global atmospheric map of nitrogen dioxide pollution makes clear just how human activities impact air quality.

The 2004 ENVISAT & ERS Symposium provided a forum for investigators to present results of on-going research project activities and assess the development of applications and services.

Hurricanes are one of those forces of nature that can only fully be captured by satellite imagery. For Hurricane Frances, currently thundering towards the United States coast, ESA's Envisat is going one better, peering through the hurricane from top to bottom, even helping to 'see' under the waves to map hidden forces powering the storm.

This season's Antarctic ozone hole has swollen to an area of ten million square kilometres from mid-August - approximately the same size as Europe and still expanding. It is expected to reach maximum extent during September, and ESA satellites are vital for monitoring its development.
