SETI Project Stopped


The search for extra-terrestrial life (ET) seems to have stopped – at least for the moment, since the decades-long search for extraterrestrial life will be closing down due to a very common reason, which is the lack of funding. What is one going to do with a $50 million alien telescope array?
SETI (short for Search for ExtraTerrestrial Intelligence) is a project that has been long running, using..

the power of idle computers in the search for life apart from planet earth, where the original plans actually included the Allen Telescope Array, which was part of the Hat Creek Radio Observatory, where it was meant to house up to 350 dishes.

"This means that the equipment is unavailable for normal observations and is being maintained in a safe state by a significantly reduced staff," CEO Tom Pierson said.
SETI, which stands for Search for Extraterrestrial Intelligence, is the scientific institute made famous in Carl Sagan's novel Contact.  The organization has spent half a century searching the universe for radio signals from deep space that might indicate we are not alone.
The financial problems specifically involve the operation of the ATA, a set of radio dishes dedicated to searching for alien signals.

Although the ATA was paid for by the SETI Institute, it is managed and operated by the radio astronomy lab of the University of California at Berkeley.
SETI senior astronomer Seth Shostak said the facility needs about $2m-$3m a year to function, and the scientists need an additional $5m to fund a two-year project to listen for possible radio signals coming from the exoplanets found by NASA’s Kepler satellite.
Until now, the funds needed to operate the observatory have come from a combination of private donations, the U.S. National Science Foundation (NSF) and the state government of California.
However, funding from the NSF has been reduced to roughly a tenth of its former level, while growing budget shortfalls in the state of California have severely cut the amount of state funds available for support of the HCRO site.

"As it happens, Berkeley's budget is way down – the state of California is in terrible financial circumstances because of the economic downturn," Shostak told the Guardian.
"Consequently, they don't have the money to keep the doors open and pay the electric bills and pay the staff at the antenna. And we don't either, because we run our SETI projects mostly based on private donations, and those are down as well."
There is some hope of raising the money through working with the U.S. Air Force on future projects, Pierson said.   One idea being considered is a collaborative project between the ATA and the USAF's space surveillance network to track space debris, which can damage satellites and space vehicles.
However, given impending cuts in federal funding for the U.S. military, such a plan is uncertain.
"The other possibility is that private donations could bring the telescope back to life and keep it working," Shostak said.
The ATA is the SETI Institute's largest facility, and its only dedicated one. Its shutdown means astronomers will need to rely on data gathered during downtime from other telescopes, lessening its chances of finding any alien signals.
