Satellites See Unprecedented Ice Melt in Greenland

For several days this month, Greenland's surface ice cover melted over a larger area than at any time in more than 30 years of satellite observations. Nearly the entire ice cover of Greenland, from its thin, low-lying coastal edges to its two-mile-thick center, experienced some degree of melting at its surface, according to measurements from three independent satellites analyzed by NASA and university scientists.

Understanding Risk Forum: Importance of satellite data stressed

The risk of natural disasters can be reduced by understanding our environment and the fundamental forces that shape it. Earth-observing satellites can provide vital information to mitigate and prepare for disasters. These data can support risk assessment for a range of hazards, from hydrometeorological risks to geo-hazards such as landslides and terrain subsidence.

Bangladeshi Meteorological Department

The Bangladesh Meteorological Department is the authorised Government organisation for all meteorological activities in the country. It maintains a network of surface and upper air observatories, radar and satellite stations, agro-meteorological observatories, geomagnetic and seismological observatories and meteorological telecommunication system. The Department has its Headquarters in Dhaka with two regional centres i.e. the Storm Warning Centre (SWC) in Dhaka and the Meteorological & Geo-Physical Centre (M & GC) in Chittagong.

ESA hands over weather satellite for operations

ESA's weather satellite MSG-3 has smoothly traveled 36 000 km above the Equator. The satellite is now nearly in its geostationary orbit, drifting slowly east toward its final orbit position. With MSG-3 healthy and now in its place of work, ESA has handed operations over to Eumetsat, the European Organisation for Exploitation of Meteorological Satellites, who then commissions the payload and carries out routine operations. When fully operational, Eumetsat will rename MSG-3 as Meteosat-10. Meteosat-10 joins its predecessor Meteosat-9 to keep a constant watch on developing weather systems.

Australia becomes Landsat 8 partner

Australia became an international collaborator on the new US-satellite mission Landsat 8, under an agreement signed on 12 July 2012 with the United States Geological Survey. Landsat 8, the latest in the series of Landsat satellites, is expected to launch in January 2013. It will continue almost forty years of operation of the Landsat series of land observing satellites, part of the Landsat Data Continuity Mission, which is the longest continuous record of the Earth’s surface as seen from space.

50 years of satellite communications

10th July 1962 marked the birth of satellite communications. Exactly 50 years ago today the Telstar satellite commenced its journey into space from Cape Canaveral and became the first ever active communications satellite. It carried the first live trans-Atlantic TV broadcasts. Telstar was built by a team at Bell Telephone Laboratories and incorporated many innovations such as the transistor and the 3,600 solar panels that powered the satellite and which had been invented by Bell Labs.

ESA: End of mission for navigation satellite GIOVE-A

With the initial satellites of the Galileo constellation working well in orbit, ESA decided to end the mission of its pioneering GIOVE-A navigation satellite. Launched on 28 December 2005, this first experimental satellite performed the vital task of securing the radio frequencies provisionally set aside for Galileo by the International Telecommunications Union. It also flight-tested Galileo atomic clocks and other equipment in space for the very first time and investigated the radiation environment of medium-altitude orbits, never used before by a European mission.

NOAA improves weather satellite

Seven months after launch, data is now flowing from a new generation of instruments onboard the Suomi NPP satellite, a joint NASA/NOAA mission being used in NOAA’s global numerical weather forecast system. NOAA is the US National Oceanic and Atmospheric Administration. The Suomi NPP polar-orbiting satellite circles the Earth every 102 minutes, flying 512 miles above the surface, capturing data from the land, oceans and atmosphere.
