The loss of the Envisat satellite is affecting services by Europe´s Global Monitoring for Environment and Security program. Efforts are being coordinated with other space agencies to fill some of the gaps, but the situation adds further urgency to launch the Sentinel missions. Carrying an array of sophisticated instruments, Envisat provided a continuous stream of information about the state of our planet for 10 years. Envisat not only advanced science, but also supplied data for...

[ Watch the Video ] In the early hours of 1 March 2002, the largest Earth observation satellite ever built soared into orbit from ESA´s launch base in Kourou, French Guiana. For a decade, Envisat has been keeping watch over our planet. The eight-ton satellite has doubled its planned five-year lifetime, circling Earth more than 50 000 times. With ten sophisticated optical and radar sensors, the satellite is continuously observing and monitoring Earth´s land, atmosphere,...

   ESA´s Envisat observation satellite yesterday completed its 50,000th circuit of Earth — travelling 2.25 billion km since its launch nearly a decade ago. Envisat orbits our planet every 100 minutes, speeding along at more than seven kilometers per second. During this milestone spin around the world on 22 September, the satellite passed from the Arctic to the Antarctic, catching glimpses of northern Greenland and New Zealand. Launched on 28 February 2002, the...

Originally designed to monitor Earth for just three years, ESA's veteran ERS-2 satellite is still in orbit and going strong after 15 years of delivering essential data to improve our understanding of Earth and climate change. ERS-2 was launched on 21 April 1995 to follow on from the first European Remote-Sensing mission, ERS-1, which had been in orbit since 1991. At the time, these two satellites were the most sophisticated European Earth observation spacecraft ever developed, delivering...

By merging more than a decade of atmospheric data from European satellites, scientists have compiled a homogeneous long-term ozone record that allows them to monitor total ozone trends on a global scale "“ and the findings look promising. Scientists merged monthly total ozone data derived from the vertically downward-looking measurements of the GOME instrument on ESA's ERS-2 satellite, SCIAMACHY on ESA's Envisat and GOME-2 on the European Meteorological Satellite Organization's...

The SCIAMACHY sensor on ESA's Envisat satellite has provided scientists with invaluable data on our planet, allowing them to map global air pollution and the distribution of the most important greenhouse gases. Earlier this year, its sights were set on our nearest planetary neighbor, Venus. In March and June, SCIAMACHY (Scanning Imaging Spectrometer for Atmospheric Chartography) captured visible and near-infrared spectra of sunlight reflected by Venus. These observations, acquired from a...

Using data from the satellite-based MIPAS and GOME-2 instruments, scientists have for the first time detected important bromine species in the atmosphere. These new measurements will help scientists to better understand sources of ozone-depleting species and to improve simulations of stratospheric ozone chemistry. Despite the detection of bromine monoxide (BrO) in the atmosphere some 20 years ago, bromine nitrate (BrONO2) was first observed in 2008 when scientists from the Karlsruhe...

The 2008 ozone hole "“ a thinning in the ozone layer over Antarctica "“ is larger both in size and ozone loss than 2007 but is not as large as 2006. Ozone is a protective atmospheric layer found in about 25 kilometers altitude that acts as a sunlight filter shielding life on Earth from harmful ultraviolet rays, which can increase the risk of skin cancer and cataracts and harm marine life. This year the area of the thinned ozone layer over the South Pole reached about 27 million...

Using data from the SCIAMACHY instrument aboard ESA's Envisat environmental satellite, scientists have for the first time detected regionally elevated atmospheric carbon dioxide "“ the most important greenhouse gas that contributes to global warming "“ originating from manmade emissions.More than 30 billion tons of extra carbon dioxide (CO2) is released into the atmosphere annually by human activities, mainly through the burning of fossil fuels. According to the latest report by...

Air pollution is becoming one of the biggest dangers for the future of the planet, causing premature deaths of humans and damaging flora and fauna. With their vantage point from space, satellites are the only way to carry out effective global measurements of air-polluting emissions and their transboundary movement. Scientists and researchers from around the world gathered at ESRIN, ESA's Earth Observation Centre in Frascati, Italy, last week to discuss the contribution of satellite data in...
