so why SETI doesnt get a copy of all these data and process them to check if any alien signals in it? :P

Someone would have to "pay" for the data to be copied, a fund raiser has just been held to purchase the HDD's and transport case necessary for getting data from Green Bank. No one has mentioned who will actually pay for these HDD's to get from Green Bank and back.

Remember SETI@Home has no money to pay for this sort of thing and would have to rely on the ASKAP to donate everything. "Sometimes it is the people no one imagines anything of who do the things that no one can imagine."

Another reason is that satellite time costs money. SETI@Home gets a free ride off anyone paying for the Arecibo satellite - anytime someone rents the satellite, the SETI@Home data recorder is running to collect data.

SETI@Home is not likely to get the same deal from other telescope arrays. This means they would have to pay for observation time, which we all know SETI@Home has little to no money to pay for.

Many donors are happy to give money for hardware upgrades or donate hardware directly, but it seems very few people are willing to donate the cash required to pay the SETI@Home staff or observation time on the satellites.

we dont need observation time, only a copy, or free ride. someone needs to do it
if it s not seti then it will be who ?

The location is ideal because it is 'radio quiet', or lacks man-made radio signals that would interfere with the antennas picking up astronomical radio signals.

...

But will the telescope be looking for extra terrestrial life?

'It's not a primary of many of these surveys, but it's certainly a secondary goal that you almost get for free,' Boyle said.

'As you're surveying the sky, particularly over wide areas of sky looking for objects, you are also increasing the search volume for signals from extraterrestrial life.'

it has been the SETI only goal to do that since 30 years and after all these years... they will let another grp to get all the credits ?
Seti with all our computers has the most powerful computing force in the world that will never exist.

Actually, you'll still need observation time to double-check any potential signals. But most of the world doesn't allow for "free rides". Arecibo may be a special deal. If they can get that deal with another satellite provider, then all the better for SETI@Home, but it shouldn't be expected to have a free ride.
