Scientific Measurements


Phoenix's Robotic Arm (RA) is the single most crucial element to making scientific measurements. The robotic arm combines strength and finesse to dig trenches, scrape water ice, and precisely deliver samples to other instruments on the science deck. Also, the robotic arm carries a camera and thermal-electric probe to make measurements directly in the trench.

The following table shows the relationships between Phoenix's science objectives, the scientific measurements to be made, and the instruments that will make these measurements.
