Nasa Releases Mass Water in Space and UFO Comes!?

According to Jamie maussan, The shuttle Atlantis released a ton of water into space and a mysterious UFO goes near to investigate..
Hang on..Back up a second!? Water being released into space by NASA? Now forgive me if there is some plausible explanation that I did not know about. But try as I might I have not found anything online about the shuttle releasing water, let alone why.
Now why would NASA release a large amount of water into space?
Is it just a standard procedure for the shuttle Atlantis to release what it doesn't need in fluid or is it something more sinister like secret experiment we don't know about or weather manipulation?.. Warning or gift to the extraterrestrial? It may all sound crazy but isn't thousands of litres of water being released into space Crazy too considering the damage it could do in the universe. And I say could not will as I like everyone do not know 100% how the universe works. Most Astronomers know that when it comes to the universe nothing is certain. And I believe that to be true :-)
