The images show that the arm has moved quite a bit since it was first deployed on Sol 6 and has been used to collect and analyze a variety of soil and ice samples. The arm has also been used to take pictures of the lander and its surroundings and has even been used to scratch the surface of the Martian soil.

The pictures show that the arm is in good condition and is still fully functional after 90 sols of use. The arm has been a very important tool for the Phoenix mission and has been used to collect data and images that have helped scientists to better understand the Martian environment.
