ICON satellite to study the ionosphere, the boundary between Earth’s atmosphere and space

Science
Oct. 8 (UPI) -- Inside the outermost layer of Earth's atmosphere, billions of negatively charged electrons bounce freely for long periods of time before being tamed by positive ions. The layer, the ionosphere, and its highly variable plasma waves can disrupt GPS signals and other radio-wave-based communication systems. To better understand the ionosphere and pinpoint the forces responsible for its variability, scientists at NASA are sending a specially equipped satellite into space to observe the enigmatic layer. The Ionospheric Connection Explorer, or ICON, developed by a team of scientists and engineers at the University of California, Berkeley, will be carried into space this week by Northrup Grumman's Pegasus XL rocket. "ICON is built specifically to understand the connection between...
Virgin Orbit selects RAF pilot as it plans satellite launch program

Virgin Orbit selects RAF pilot as it plans satellite launch program

Business
Oct. 4 (UPI) -- Virgin Orbit, a private company planning launches of orbital satellites, announced that a Royal Air Force pilot will join its team. Flight Lt. Mathew Stannard will join the Virgin Orbit program in a three-year contract. He will be one of the company's pilots in the trials of Boeing 747-400 aircraft from which satellites will be launched. The announcement was made on Thursday in California. Stannard is currently a Typhoon pilot with the RAF's test an evaluation squadrons. Virgin Orbit has a business relationship with the RAF and the U.S. Air Force in demonstrating the utility of launching small satellites by means other than traditional vertical rockets. The first "air launch" of a rocket and satellite is planned for the autumn. Last week the first rocket, LauncherOne, was...
Europe launches second EDRS space laser satellite

Europe launches second EDRS space laser satellite

Science
Europe has launched the second satellite in its space laser telecommunications network.It will use optical beams to pull pictures and data from other spacecraft and then speed that information to the ground.EDRS-C, as it is known, was sent into orbit on Tuesday by an Ariane-5 rocket from the Kourou spaceport in French Guiana.It joins the first node in the network, EDRS-A, which was put up in 2016.That spacecraft was positioned over Central Africa to service Europe.The new satellite will sit slightly to the east, where it will provide additional capacity.The European Data Relay System is a joint venture between the European Space Agency and aerospace giant Airbus.It is used predominantly by the European Union's Sentinel-1 and Sent...
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...
