Satellite image shows temperatures soaring across Europe

Satellite image shows temperatures soaring across Europe

Science
June 28 (UPI) -- It is really hot in Europe, and the European Space Agency has the satellite images to prove it. Scientists with ESA generated a heat map of continental Europe using data collected by the space agency's Copernicus Sentinel-3's Sea and Land Surface Temperature Radiometer. The map shows the temperature of the land across Europe on June 26. The heatwave currently gripping Europe is producing record temperatures for June. In France, thermometers are registering 100 degrees Fahrenheit, moving Paris officials to ban certain vehicles inside the city. Cities throughout Spain, Italy and Germany also experienced extreme highs on Wednesday and Thursday. In Catalonia, wildfires fueled by the extreme heat and winds are quickly spreading. The heatwave has already claimed several lives,...
Antarctic glaciers to honour ‘satellite heroes’

Antarctic glaciers to honour ‘satellite heroes’

Science
A series of glaciers in the Antarctic are being named after the satellites that have revealed the changing state of the White Continent.The spacecraft, from Europe, the US and Japan, have all contributed important observational data which confirms a picture of accelerating ice loss. They include the pioneering American Landsat series of satellites and Europe's new Sentinel fleet. Their namesake glaciers run parallel to each other in Palmer Land. This is a sector on the western side of the Antarctic Peninsula. It's an area studied by Dr Anna Hogg, who was frustrated that the glaciers she was looking at were known only by their coordinates on a map.The Leeds University scientist proposed the satellite names idea to the UK Antarctic Place-names Committee. It...
Satellite plane-tracking goes global

Satellite plane-tracking goes global

Science
Tracking aeroplanes anywhere in the world just got a lot easier.The US firm Aireon says its new satellite surveillance network is now fully live and being trialled over the North Atlantic.The system employs a constellation of 66 spacecraft, which monitor the situational messages pumped out by aircraft transponders.These report a plane's position, altitude, direction and speed every eight seconds.The two big navigation management companies that marshal plane movements across the North Atlantic - UK Nats and Nav Canada - intend to use Aireon to transform their operations.The more detailed information they now have about the behaviour of aeroplanes means more efficient routing can be introduced. This ought to reduce costs for airlin...

ULA launches 10th WGS comms satellite for U.S. military

Science
March 15 (UPI) -- United Launch Alliance launched a communications satellite for the United States Air Force on Friday evening at 8:26 p.m. EST. ULA's Delta IV rocket had a successful launch and jettisoned its liquid rocket motors on time as it entered the atmosphere. Just a few minutes after liftoff, the first and second stages separated. The rocket's second stage executed a series of engine burns to properly position the payload. After a technical glitch delayed proceedings, ULA released a new liftoff target of 7:52 p.m. Just minutes later, ULA announced a problem with NASA's Tracking and Data Relay Satellite System "will delay liftoff beyond our new ... launch time." The sun is rising over the #DeltaIV with #WGS10 on the launch pad this morning. Liftoff planned for today, March 15 at ...

Jan. 19 (UPI) -- A rocket carrying a spy satellite launched Saturday from Vandenberg Air Force Base in Southern California after bad weather and technical problems delayed the sendoff for more than one month. At 11:10 a.m. Pacific time, the United Launch Alliance Delta IV Heavy rocket lifted off, carrying a U.S. National Reconnaissance Office satellite into orbit, United Launch Alliance said in a news release. ULA in a joint venture of two competitors, Lockheed Martin and Boeing. NROL-71 was the 132nd successful launch since the company was formed in December 2006, according to its website. The alliance said the satellite is "in support of our country's national defense." "Congratulations to our team and mission partners for successfully delivering this critical asset to support national...
