Why the hell is NASA wasting public money on giving publicity to this group of attention seekers, yes I'm looking at you Paul McCartney.

In case you haven't heard NASA will be broadcasting the Beatles song Across the Universe towards Polaris on the 4th.

Amazing! Well done, NASA! Send my love to the aliens. All the best, Paul.

Yoko Ono of course had her bit to say as well.

I see that this is the beginning of the new age in which we will communicate with billions of planets across the universe.

As nutty as ever, has anybody told her that Polaris is 400 odd light years away? Wait, she probably doesn't even know what that means. Enjoy waiting 800 odd years for a response, if any, Yoko.

Why NASA are doing this is totally beyond me. There is zero scientific justification to this, all it seems to be doing is wasting US tax payers money on promoting the Beatles. NASA's budget is tight enough, with dozens of scientific programs being cut without wasting money on this nonsense.

If you want to send messages out into the cosmos (we've only done this once or twice before, it is expensive), at least do it properly. Use some mathematical sequence which can only be interpreted as artificial, and send it to high probability targets that are closer to the Earth - and then keep transmitting.

The private exploitation of space needs to stop, yes that means you too Richard Branson, Virgin Galactic - even the name is false advertising! I think its time for a campaign - Keep Space Public.
