I did it as a joke to Dave's signature. I did get a sticker with the mission logo. To my knowledge, its not out for sale yet. Also ordered a couple of shirts (polo and t-shirt) that JPL offered for MSL employees.
Back on topic, its exciting that Opportunity, or MER2, is entering the crater.
Hopefully the rovers wont experience a dust storm like that in the near future, or in their future in general.
Astronomy picture of the day is so cool. A few days ago was crazy cool...
