Seriously. The amount of difference between Chinese and Latin-based languages is so freakin enormous that we can't even translate modern texts right.
Huh?? Who is the "we"? There exists quite a few people who can very precisely translate Chinese (Mandarin, Cantonese or Classical along with their many dialects and other mutually-unintelligible languages spoken in China) into any modern or dead (but well understood) language you'd like - and no, no one person could likely perform all permutations of these translations. I myself have no trouble translating Mandarin (specifically 普通话 / 国语) to English or vice-versa. All that is required is a suitable grasp of both languages and of the cultural aspects (idioms, allegories, metaphors, etc) embedded within the sample to be translated. Yeah, some idioms still are hard for me - but there certainly exists experts who aren't tripped up.
I realize that there are times where one might doubt this. The ever present "chinglish" or "engrish" examples found on signs, product labels and documentation, etc. shows how hard it is for someone not knowing a lot about both languages to produce a good translation. And it shows how hard it is for automated systems to render good translations over a broad range of samples.
Now, to translate a language you know nothing about is tricky at best. Lacking any knowledge of the culture or even the nature of the creature using it or of the environment in which that creature lives makes it practically impossible. There are examples of dead languages used by human cultures here on earth that have so far resisted our understanding. And these are relatively easy.
But, suppose the message was specifically crafted by an intelligent being with the INTENT that it be understandable to any sufficiently advanced culture. That kind of message would necessarily be based on simple (at first) encodings of universal principles (math, physics, etc) and completely free of cultural or environmental biases. Such a message could be decoded with effort and could be used to build up a synthetic language used to encode nearly any manner of subject.
This EXERCISE by the NSA seems to be an example of identifying and decoding such a message. I doubt it is more than that.
This particular exercise does seem to ignore the issue of message transport encoding suitable for broadcasting (directed or not) a message where its integrity must be be maintained over interstellar distances where even tightly collimated coherent beams would diverge substantially to cause power at the receiver to be relatively low and yet still detectable and able to carry information in the presence of all manner of noise and signal attenuating conditions.
Consider how little power even a 1 gigawatt transmitter could deliver to a 100 meter disk even when its beam is constrained to only the area covered by orbits of the terrestrial planets (radius of about 250,000km) of our solar system - that's about 0.5 microwatts if I did my math right. That, I believe, would be an amazingly (impossibly?) narrow beam, assuming interstellar distances, sent by someone who already knows or suspects our star holds at least one planet inhabited with an advanced civilization. More likely the beam would be very broad or would be an omnidirectional broadcast so the transmitter would have to be ridiculously powerful to produce a few picowatts worth of signal at even a very large receiver more than a handful of lightyears away. Not impossible, but not trivial. Obviously SETI folks think this is feasible.
This encoding (in frequency, modulation and information encoding) would also have to be devised in a way that is discoverable and robust (with sufficient redundancy) but is suitable for carrying useful amounts of information. And it has to work with no requirement for the receiver to ask "can you repeat that". I am sure this too is readily solvable by the suitably trained and capable mathematicians, scientists and engineers we have today. Further, I assume any other truly advanced culture capable of having the intent to and of building the means to send such a message could do this as well.

I am fairly certain NASA does not work with astrologers.

If this is real, why has it not been picked up by the news or at the least, sites like ATS? Unless it's possible to upload fake documents to the NSA website, I don't see how this could be made up. I wonder what all those messages say... lol I imagine it being like galactic voicemail!

it seems that this year, there has definatly been a spike in non-terrestrial presence

a simple ATS search would have revealed these have been on ATS before, and recently!
they are a HOAX...
ok?

How ironic of you to tell me to do a search without even reading through the thread to see how many times I've apologized for re-hashing material already covered... A simple read would have let you know your post is more redundant than this thread. Ok? seeya
