The most detailed portrait ever of the Earth's land surface is being created with ESA's Envisat environmental satellite. The GLOBCOVER project aims at producing a global land cover map to a resolution three times sharper than any previous satellite map.
Since the launch of Envisat in 2002, numerous validation activities have been carried out to confirm that the data received from its ten optical and radar instruments are as accurate as possible.
The final stretch of the Scott Dunn Polar Challenge is approaching: 44 competitors on 16 teams from all over Britain and Ireland are racing on skis, pulling sledges to the 500-kilometre-distant Magnetic North Pole. In this extreme environment, radar ice images from ESA's Envisat help ensure competitors keep safe.

ERS-2 is a notable European engineering achievement, reaching the milestone of 10 years in orbit on 21 April 2005 with all instruments still working and providing excellent data.

Despite the efforts deployed to understand the GOMOS instrument anomaly, the investigation team does not yet fully comprehend the problem.
The SCIAMACHY sensor aboard Envisat has performed the first space-based measurements of the global distribution of near-surface methane, one of the most important greenhouse gases. As reported in Thursday's issue of Science Express, the results show larger than expected emissions across tropical land regions.

Envisat radar imagery confirms that the B-15A iceberg ? the world's largest floating object ? is adrift once more after two months aground on a shallow seamount. This latest development poses a renewed threat to the nearby pier of land-attached ice known as the Drygalski ice tongue.

Spring gets off to an unseasonal start across Europe: this Envisat image from last week shows the continent covered by snow all the way down from Sweden down to Italy.

Acquired from orbit 800 kilometres away, this Envisat image shows two volcanoes erupting simultaneously on Russia's snowy Kamchatka Peninsula this week.

Australian researchers have found Envisat's MERIS sensor can detect coral bleaching down to ten metres deep. This means Envisat could potentially monitor impacted coral reefs worldwide on a twice-weekly basis.
