A 500-foot-wide asteroid called 2010 XC15 will pass by Earth on December 27. Scientists at the University of Alaska Fairbanks (UAF) and NASA want to examine the 2010 XC15 space rock to test their preparation against Apophis. This dangerous asteroid might hit our planet in 2029. The researchers will use the HAARP (High-frequency Active Auroral Research Program) array to shoot 9.6 megahertz radio waves at the 2010 XC15 asteroid. HAARP is a government-funded research program that generally studies the ionosphere (part of Earth’s atmosphere at 50 to 400 miles above the surface). However, this will be the first time it...

NASA is teaming with scientists from the University of Alaska Fairbanks’ Geophysical Institute to send about 9.6 million radio waves to 2010 XC15, an asteroid that will pass by about twice the distance from Earth to the Moon.

(Photos and image at link.)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 the Earth and the moon. Results of Tuesday’s experiment at the High-frequency Active Auroral Research Program research facility at Gakona could aid efforts to defend Earth from larger asteroids that could cause significant damage.“We will be analyzing the data over the next...
