The $80M doesn't cover the launch costs. That would be part of the $2.4B for the overall rover project.
For comparison: SpaceX's entire Falcon 1 program cost $90M over 6 years. That was to develop two new rocket engines (Merlin & Kestrel), build out the launch site on Omelek Island, and launch five times.
