Hailing Frequencies Open? Communication Via Neutrinos Tested Successfully

by Nancy Atkinson on April 11, 2012

In science fiction – like in Star Trek, for example — interstellar communication was never a problem; all you needed was to have Urhura open up hailing frequencies to Starfleet Command. But in the real universe, communicating between star systems poses a dilemma with current radio technology. There’s also a very real problem today for operating spacecraft in that communications are impossible when a planetary body is blocking the signal. One of the more outlandish methods proposed for solving deep space communication problems has been to devise a technique using neutrinos. But now, it turns out, using neutrinos for communication might not be that crazy of an idea: communicating with neutrinos has, for the first time, been tested successfully.

Scientists of the MINERvA collaboration at the Fermi National Accelerator Laboratory successfully transmitted a message through 240 meters of rock using neutrinos. The team says their demonstration “illustrates the feasibility of using neutrino beams to provide a low-rate communications link, independent of any existing electromagnetic communications infrastructure.”

The scientists used the a 170-ton MINERvA detector at Fermilab and a NuMI beam line, a powerful, pulsed accelerator beam to produce neutrinos. They were able to manipulate the pulsed beam and turn it — for a couple of hours — into a sort of “neutrino telegraph,” according to R&D magazine.
