On March 18 the scientists said they believe that the increased area of sea ice this winter is due to recent weather conditions, while the decline in perennial ice reflects the longer-term warming climate trend and is a result of increased...Delta II launches GPS IIR-19 satelliteA Delta II rocket launched at 06:10 GMT this morning, with the GPS IIR-19 navigation satellite. The spacecraft, which forms part of the US Air Force's NAVSTAR Global Positioning System, has been successfully delivered into a Medium Earth orbit. The rocket flew in the 7925-9.5 configuration, with 9 GEM-40 solid-rocket boosters, an Extra Extended Long Tank Thor first stage, a Delta-K second stage, a Star 48B third stage, and a 9.5 ft (2.9m) diameter payload fairing. Launch was conducted by...Atlas V successfully launches spy satelliteAn Atlas V rocket has successfully launched a classified spy satellite for the United States National Reconnaissance Office (NRO). The satellite, currently known to the public as NRO L-28, or Launch 28, is believed by amateur enthusiasts to be a signals intellegence (SIGINT) spacecraft, known by the codename Trumpet. The Atlas V carrier rocket flew in the 411 configutation, with a 4 metre diameter fairing, one solid rocket motor, and a single-engine Centaur upper stage. The rocket lifted off...Space Shuttle Atlantis completes mission STS-122Space Shuttle Atlantis has landed on runway 15 of the Kennedy Space Center Shuttle Landing Facility, completing the STS-122 mission to the International Space Station (ISS). Landing occurred at the earliest opportunity today, with Atlantis touching down at 14:07:10 GMT (09:07:10 local time), following a de-orbit burn at 13:00 GMT, and entry interface at 13:35.

A modified SM-3 missile was launched from the USS Lake Erie at 03:26 GMT this morning, and intercepted the USA-193 satellite around three minutes later. It has been reported that the satellite has broken into around 80 pieces, some of which have already re-entered the Earth's atmosphere. The SM-3 missile was designed to shoot down other missiles, however for this...GOES-12 weather satellite fails during adjustmentThe weather satellite GOES-12, which provides most of the weather pictures for the United States, became unusable on Tuesday, December 4. The satellite is positioned in geostationary orbit over the Amazon. A normal station-keeping maneuver to adjust its location was not completed as usual and services could not be continued. The National Oceanic and Atmospheric Administration (NOAA) operates the satellites for its National Weather Service (NWS). NOAA's satellite division intends to...Satellite ModemWhat is satellite modem..? A device used to transmit and receive signals from a satellite transponder. For transmission, it modulates digital data signals from a multiplexing device into a carrier frequency for delivery to an upconverter, amplifier and antenna. For receiving, it converts the frequencies from the downconverter into digital pulses for the multiplexor.Satellite modem is a revolutionary communications system that enables you to surf the web, send e-mail and transfer a host of other...Watch Satellite TV Online – Answers to Whether you Should WatchPeople are often caught in the dilemma of whether they should watch satellite TV online or go for the conventional TV set.
