1. 1. Rationale: APPROXIMATE ESTIMATION FOR HYDROTHERMAL BAND: ZONE INSIDE OF EBERSWALDE CRATER Juan C. Echaurren Codelco Chile North Division Fourth MSL Landing Workshop Latitude/Longitude/Window of Probability 1: ~ -23.913  S, 326.481  E ; 2: ~ -23.836  S, 326.500  E Is shown here, the hydrothermal band that was predicted with the models used, and the intersection between this band, and one portion of the “Delta”. This intersection defines a window of probability, which, generates the possibility of finding traces of microscopic life on that region. The edges of this window are not absolute, i.e., targets can be located around of them, and targets can be located around of the hydrothermal band too. 2. Morphology and Mineralogy: Possibility of to find argillaceous limestone, and traces of microscopic organic life. 3. What will the rover specifically do here? The rover will use the CheMin instrument for to detect traces of argillaceous limestone.

2. 2.8 km 2 1 Intersection between, a portion of the hydrothermal band, and a portion of the “Delta” (window of probability) Hydrothermal band of ~ 0.790 km

3. 2.88 km Intersection between, a portion of the hydrothermal band, and a portion of the “Delta” (window of probability) 2 1 568 m 2 1 Window of Probability
