A powerful transmitter in remote Alaska sent long wavelength radio signals into space Tuesday with the purpose of bouncing them off an asteroid to learn about its interior. The asteroid, 2010 XC15, is estimated to be about 500 feet across and is passing by Earth at two lunar distances, which is twice the distance between […]
An experiment to bounce a radio signal off an asteroid on Dec. 27 will serve as a test for probing a larger asteroid that in 2029 will pass closer to Earth than the many geostationary satellites that orbit our planet. The High-frequency Active Auroral Research Program research site in Gakona will transmit radio signals to asteroid […]
An unexpected find in a University of Alaska Fairbanks archive has revealed more information about the oft-debated April 1910 Sourdough Expedition climb of Denali, North America’s highest mountain. Photographs found by UAF Geophysical Institute professor Matthew Sturm in the university’s Rasmuson Library archives in October show the climbing party at about 16,500 feet — far […]

The satellite, once in full operation, will bring timely data about the weather, sea ice, wildfires and much more to Alaskans for the next seven […]
