Dec. 26, 2022:<\/strong> <\/p>\n\n\n\n

Researchers from NASA and the University of Alaska are about to perform an unusual radar experiment. <\/p>\n\n\n\n

They\u2019re going to ping a near-Earth asteroid using shortwave radio. The target is a 500-ft-wide space rock named \u201c2010 XC15<\/a>.\u201d When it passes by Earth on Tuesday, Dec. 27th, the HAARP array in Alaska will hit it with a pulse of 9.6 MHz radio waves.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Radio astronomers ping asteroids all the time. What\u2019s unusual about this experiment is the frequency: 9.6 MHz is hundreds of times lower than typical S-band<\/a> and X-band<\/a> frequencies used by other asteroid radars. The goal is to probe the asteroid\u2019s interior.<\/p>\n\n\n\n

Lead investigator Mark Haynes of the Jet Propulsion Laboratory (JPL) explains: \u201cThe low frequencies we are using can penetrate the asteroid, unlike S-band or X-band frequencies which reflect mostly off of the surface. Ultimately the idea is to use echoes to form tomographic images of asteroid interiors.\u201d<\/p>\n\n\n\n

Knowing the internal structure of an asteroid could come in handy \u2014 especially if you need to destroy it. 2010 XC15 poses no threat 770,000 km from Earth. Tomorrow\u2019s experiment is proof-of-concept for a scarier object: Asteroid Apophis<\/a>, which will buzz Earth closer than many satellites on April 13, 2029. If shortwave asteroid radar works for 2010 XC15, it should work for Apophis, too, giving planetary defense experts key data about the asteroid\u2019s vulnerabilities.<\/p>\n\n\n\n

<\/p>\n\n\n\n

HAARP will transmit a continually chirping signal to asteroid 2010 XC15 at slightly above and below 9.6 MHz. The chirp will repeat at two-second intervals. The University of New Mexico Long Wavelength Array near Socorro, NM, and the Owens Valley Radio Observatory Long Wavelength Array near Bishop, CA, will receive the reflected signal.<\/p>\n\n\n\n

\u201cThis will be the lowest frequency asteroid radar observation ever attempted,\u201d notes Lance Benner, a co-investigator from JPL. If the experiment works it could mark a significant advance in asteroid radar. Stay tuned!<\/p>\n\n\n\n
