ENVISAT 2000 is the title of this video: Since the first satellite, space has far become the best perspective of observing the Earth, including natural or man-made disasters, global warming, climatic changes, pollution and deforestation. It was for this reason ESA decided to build ENVISAT, an orbital laboratory that supports local and global study of our planet. ENVISAT is also one of the major tools responding to the European Commission’s initiative son global monitoring of the environment and security. ENVISAT is the largest satellites build in Europe with ten instruments to observe and monitor a series of parameters relevant to “the health of the Earth”.
0:41 – Introduction: Satellites best to monitor changes on Earth
1:17 – Animated video, pre-ENVISAT, of existing satellites observing the Erath, all optical or radar satellites.
1:38 – Envisat construction in European factories.
1:52 – Animated video of ENVISAT orbiting the Earth. ENVISAT is the logical continuation of ESA’s ERS satellites.
2:03 – Video of disasters on Earth
2:14 – In Max Planck Institute, Germany, the scientist Paul Crutzen discovered at the end of the seventies that the ozone layer was not able to withstand the barrage of chemicals unleashed on it by humans. He was nominated the Nobel prize in 1995 for his work in chemistry.
2:35 Professor Paul Crutzen, former Director Division of Atmospheric Chemistry, Max Planck Institute for Chemistry, explains the advantages of looking on the Earth from satellites.
3:04 ENVISAT is the largest satellite ever build in Europe: 10m tall weighting 8tons. Views from the integration and testing.
3:21 Jacques Louet, ENVISAT Programme Manager, explains that building ENVISAT was a major achievements for European industry.
4:00 Professor Paul Crutzen, explains the need for such a complex instrument as ENVISAT.
5:28 ENVISAT has three instruments for analysing atmospheric gasses. GOMOS, MIPAS and SCIAMACHY, will perform measurements never done before.
6:45 ENVISAT will observe the coastal regions with the instrument MERIS.
7:22 Like ERS satellites ENVISAT will also have an Synthetic Aperture Radar instrument ASAR, with a programmable beam.
9:07 ENVISAT’s instrument Advanced Along Track Scanning Radiometer (AATSR) is to establish continuity of the ATSR-1 and ATSR-2 data sets taken by the ERS-1 and ERS-2 missions.
9:15 Jacques Louet, ENVISAT Programme Manager, explains some of the final tests ENVISAT has to undergo.
9:42 ESA’s control centre ESOC in Darmstadt will test the control facilities with ENVISAT before launch.
9:51 ENISAT will be launched from Kourou onboard an Ariane 5 rocket, planned to take place in 2001, to be followed by a series of validation tests.
10:43 ENVISAT data are store onboard and supported by a high-performance infrastructure on Earth of ground stations to recover the data.
11:00 ESA ground station in Kiruna, Sweden, will receive ENVISAT data every 90 minutes. ENVISAT will also communicating with ARTEMIS for relaying data to the ESRIN data management centre near Rome, Italy. The ground data network will make available ENVISAT data within maximum 3 hours from the data take.
11:40 Professor Paul Crutzen explains that the ENVISAT data will be used by not only European scientists.
12:20 Thanks to the internet the observations will be made available to the scientific community world wide
12:44 The End
