Ion propulsion?
With the leftover tonnes in the Ariane 6-2... maybe "small" is relative. Could maybe be several times more massive than Deep Space 1. |

Ion propulsion? The proposal summary on their web page says it’s a trade to be performed whether chemical or electrical propulsion is used. I’d suspect chemical is the way to go for a fast-response mission like this to keep cost down. Remember that it starts at L2, so you can dive into the gravity well for an efficient departure. |
