After quite a long time, here I go again with some information about the whole thing:
- Another main character: A freshman-soldier. Just joined the army. A geek, who studied propulsion technology before, but was only interested in weapons. Helps out with weapons in the story (need some tasks for his storyline later on ;)
- The story starts with a man who discovers, that the mars is leaving it's orbit around the sun slowly. (No - not what you think. It woun't crash into the earth)
- Another discovery: S.E.T.I. finds out, that someone receives the signal they're sending. Someone tries to find out, if the signal changes, if it's being answered. But the way it's being answered - in very small, alomst undiscoverable packages - makes S.E.T.I. suspicious about the intensions of the receiver. Maybe it wasn't so good to let everyone know, that we're here ;)
- Yes, there will be a contact. But I am not completely sure about, how. Because it'll not be very peaceful.

Hope, that gives you an impression, how the story will change in the second part.
