The Remote Manipulator System (RMS) is a versatile robotic arm that supports both construction and operations aboard the International Space Station. Now your museum & science center guests can try it for themselves with A Call to RMS! A view of the slowly-spinning Earth provides a spectacular backdrop for this exercise in grappling a set of free-flying satellites from inside the Space Station's cupola. Each grapple is a little more challenging than the last, allowing the operator to gain experience and confidence as the simulation progresses.

A Call to RMS is also offered in a dual language Science, Technology, Engineering and Math (STEM) version, titled Working in XYZ Space. This version teaches some simple 3D math concepts and includes the ability to select English or an alternative language.
