From Mike "Mike the Mission Manager" the Mission Manager's report:
The IDD activities on Sol 2713 will begin with imaging of the IDD cable guard with the Hazcam, Navcam, and Pancam. This sequence will execute and data will be returned on 11 Sept. 2011. These images are being captured in remembrance of the terrorist attacks on September 11, 2001. The RAT cable gaurd is made of aluminum that was recovered from the remains of World Trade Center 1 and 2. The cable guard is adorned with the flag of the United States of America. While steel from the towers was repurposed in defense of the United States as part of the hull of the USS New York; this aluminum has been repurposed in the name of exploration sponsored by the United States to benefit all mankind.
