As the U.S. commemorated the 15-year anniversary of the Sept. 11th terrorist attacks, NASA shared a tribute in a place far beyond America’s borders.
NASA shared a photo on Facebook Sunday that showed the Mars Exploration Rover Mission’s memorial to the victims of the Sept. 11th attacks on the World Trade Center.
The photo was originally taken and shared with the world on Sept. 11, 2011, during the 10-year anniversary of the attacks. The memorial, located on the abrasion tool on the Opportunity rover, is an image of the American flag on a cable guard made of aluminum recovered from Ground Zero.
Back in 2001, workers at Honeybee Robotics, which was located less than a mile from the World Trade Center, built the rover’s rock abrasion tool.
