According to Space.Com: Phoenix performed the test dig Sunday in a spot just above a dent left by the scoop of its robotic arm when it first touched the soil on May 31. Researchers dubbed the dent "Yeti" because of its strong resemblance to a footprint.
NASA is claiming that this footprint was actually created on Mars by the Phoenix lander's robotic arm
"This first touch allows us to utilize the Robotic Arm accurately. We are in a good situation for the upcoming sample acquisition and transfer," David Spencer, Phoenix's surface mission manager from NASA's Jet Propulsion Laboratory in Pasadena, California, said in a statement. - from www.thelondonpaper.com.
