There are few existing robots that perform exploratory tasks in extraterrestrial environments, namely Mars or Moon. To use these robots efficiently they can perform certain tasks autonomously. However, no robot system
consisting of multiple mobile units performing cooperative tasks has yet been deployed on a celestial body. In this paper we present and evaluate a scenario for cooperation in a space mission using two mobile robots: a six-wheeled rover and an eight-legged scout robot. Additionally a scaled down mockup of a landing unit with a robotic arm and a sensor tower is used in the presented project LUNARES). Figure 1 depicts the three units in
the artificial crater environment we set up to evaluate the system's performance. The mission goal is to extract a sample from the bottom of a lunar crater and return it to the lander unit. Figure 2 shows a CAD model of the
artificial crater environment, and Figure 3 illustrates the mission from start till reaching the crater bottom.
