Planet Four Challenge Part 2

The Planet Four Challenge is off to a great start towards crossing the 5 million classification mark! As a way to extend our thanks to each and everyone who has contributed to the project, we’re holding a question and answer session tomorrow. The Planet Four Team will be answering any and all of your posted questions about Mars and Planet Four on Zooniverse Talk. Ask away in this thread, and  the team will be standing by to  answer throughout the day tomorrow.
