We are only about $325 away from unlocking Viking. I bet we could do this by Monday. It always slows down in the middle, usually with a bump toward the end.

If the title throws you off, it’s because it refers to the combined mission of Spirit and Opportunity, better known as the Mars Exploration Rovers. These twin robots helped redefine what we expect from surface missions, and this patch will finally give them their place in the series.
If you are already pledged, you can now go back in and add the new Shuttle patch, as well as ISS patch which was just added a few days ago.
