1) From the MarsDawn History file, we know there are three MN missions on their way to Mars.
2) From past information from P&H, they seem to be afilliated with the European group.
3) Again, from the History file: "The first will be the Japanese, then the Chinese, and last the Europeans"
Because of the above, the "visitor" to arrive in two weeks is NOT P&H's probes.
Further, A.S.'s messages are clearly not intended to be accecpted at face value. If I remember correctly, A.S.'s first message mentioned that his/her communication was being filtered by someone. Perhaps we are overlooking some less obvious messages within the A.S. messages.
Too bad we don't have Mushroom to pull the old files...
