Right along with the Mars walking, picture-taking Curiosity, the Lake Superior barrel retrieval project has its own remote camera, although it operates on the bottom of Lake Superior, a hard place to do business but nothing like going to Mars to do it.
The picture at the left is an enlargement of the previously published picture of the barge. The ROV, as it is called, sits within the silver colored rigging seen here on the barge Kokosing. The ROV is sent down to the bottom of the Lake where the barrels are located and gives the operators above their first opportunity to evaluate the condition of the barrels. (click picture to enlarge)
