The Mars base is mostly complete after roughly a week and a half. The primary construction goes quickly, but ordering some of the materials and the equipment takes some time, even with large sums of money to lubricate the process. After that period, improvements will likely be made by those visiting, as needs arise.
The base, as Gravitas knows, is largely sheilded by the red haze of the martian surface, and simple distance. It is also obscured somewhat by the crags of the mountain it is positioned on (since it was built around the alien device). It would however be possible, theoretically at least, for prying eyes to spot the base, and if novas were to visit, it becomes much more likely, as it is positioned on one of the higher peaks on the Martian surface (not Olympus Mons, but still a respectable third place in height).
The device is now in a position to be studied. Also of note, when the device is covered, and its solar panneling not recieving energy, it seems to switch into some sort of alternate mode. Those with electromagnetic senses note that it switches to a backup generator, though it is difficult even for nova senses to pick up, due to the excessive shielding on the device. One of the instruments on top of the device also begins to move slightly, re-orienting itself (those with mega-int or perception = or > 2 will note that it is pointing at the area of the cieling with least obstruction to the open sky).
