Pioneer One's first season has finished. The entire thing is available on youtube, or as a download if you prefer. It's a great little story about a capsule that crashes to Earth containing a Russian man, supposedly descended from cosmonauts of an old Soviet experimental launch to Mars decades ago.
I highly recommend it. The show really needs as much exposure as possible to make a second season possible, so give it a watch, and if you like it, spread the word (and let me know so I know I'm not wasting my breath here. :P)
