It's really a robust mission. |
We can directly measure water ice, and then we can fly right through the plume. |
We know that we can steer it sufficiently to sample another region of the crater. |
We will create a substantial plume, excavate a bunch of material, some of which we believe may be water ice and be able to measure that directly as the plume is created, and a great opportunity to really understand what we have there. |
