23 July 2012—In 1960, astronomer Frank Drake pointed a single radio dish at two nearby stars to hunt for signals from extraterrestrial civilizations. Since then, the search has gotten considerably more high-tech. Among those leading the charge is IEEE Member Gerry Harp, who in May took over as director of research at the SETI Institute, a position most recently held by famed signal hunter Jill Tarter. IEEE Spectrum Associate Editor Rachel Courtland talked to Harp about the track record of SETI (Search for Extraterrestrial Intelligence) so far and what can be done to improve the search. 

IEEE Spectrum: The Allen Telescope Array is the only telescope designed specifically to search for signals made by an extraterrestrial intelligence. How does it work?

Top Tech 2022: A Special Report

At the start of each year, IEEE Spectrum attempts to predict the future. It can be tricky, but we do our best, filling the January issue with a couple of dozen reports, short and long, about developments the editors expect to make news in the coming year.

This isn’t hard to do when the project has been in the works for a long time and is progressing on schedule—the coming first flight of NASA’s Space Launch System, for example. For other stories, we must go farther out on a limb. A case in point: the description of a hardware wallet for Bitcoin that the company formerly known as Square (which recently changed its name to Block) is developing but won’t officially comment on. One thing we can predict with confidence, though, is that Spectrum readers, familiar with the vicissitudes of technical development work, will understand if some of these projects don’t, in fact, pan out. That’s still okay.

Engineering, like life, is as much about the journey as the destination.
