How will the messages be sent to Gliese 581d?
After the final message was collected on Monday 24 August 2009, messages were exported as a text file and sent to NASA's Jet Propulsion Laboratory in California, where they were encoded into binary, packaged and tested before transmission. The resulting collection beeps and pauses (on and off radio signals) was sent back to Australia to the NASA/CSIRO Canberra Deep Space Communication Complex at Tidbinbilla. At midday on Friday 28 August 2009, the 70-metre main antenna, known as DSS43, transmitted the signal to Gliese 581d at a frequency of 7.145 gigahertz and a power of 18 kilowatts. The resulting signal, repeated twice over two hours, was equivalent to using the combined power of over 300 billion mobile phones at the same time. The DSS43 has supported many missions exploring our Solar System and beyond, including keeping in touch with the Apollo astronauts, providing two-way radio contact with the Mars Exploration Rovers, and deep-space missions such as the twin Voyager spacecraft and NASA's New Horizons probe to Pluto and the Kuiper Belt.

If you can read this you are an alien civilisation.
I welcome our new Alien Overlords! We come in peace!
Come visit Earth, just don't land in America - they don't seem to like alien visits.
Are you on Twitter or Facebook?
I think the surest sign that alien intelligence does exist is that none of you have tried to contact us yet.
Do your females have high standards? I'm not much to look at, but I feel as though I can't connect with anyone from earth.
Some useful numbers: Pi:3.1415926535, Planck's constant:6.626 × 10-34, e:2.71828183. If this is too advanced for you then bang those rocks together guys!
Wow 160 character, guess folks from other planets txt as well. Please come and save all the cute animals from humans.
Bite me aliens.
I'm 12 and what is this?
Hello, does everything on your planet taste like chicken? Have a good one, from Earth.
Did ET get home Safe?
I wonder if my brains are bigger than your brains? From Zac
No matter if you are a mushroom or just bacteria. Important is, you can read english finally...don't learn too much, the next message is going to be in chinese.
Hello from Earth, please come and visit us but watch out for Uranus!
When you visit our planet, dont forget to bring a charged mobile so that you can phone home (check to see if you have interplanetery roaming activated too!)
Hey I'm Katelyn. I just want to know what's with all the abductions? If you need a volunteer, please take my brothers! Take your pick. I thank you in advance. x

Why would they send a signal over a year ago, to a part of the sky we have been told they only just discovered that there is an Earth like World which could hold life?
Does anyone remember the thread where a NASA technician told us that he and his work colleague discovered anomalies showing a signal from Mars that travelled faster than light?

... well the signal is due to reach Gliese 581 in 2029.........
How the hell is that possible? As far as I know, Gliese 581 is more than 20 light years away from us and it wouldn't take only 20 Earth years for the radio signal to reach there, more like 200 years, minimum.
Gliese 581 is a red dwarf star with spectral type M3V, located 20.3 light years away from Earth in the constellation Libra.
