NASA's costs for the InSight mission are expected to be $813.6 million. Of this amount, $596.3 million was spent on spacecraft development and $163.4 million was spent for the Atlas V-401 launch vehicle. Prime mission operations are expected to cost approximately $53.9 million over 2 years. International contributions for the project's science instruments account for an additional $180 million to InSight’s total cost.
InSight accounted for 0.0023% of all spending by the United States during the 9-years of its development and prime mission operations.
InSight costs by fiscal year, U.S. contributions only. The project entered formulation in September of 2012. Technical issues with one its instruments delayed InSight's launch from 2016 to 2018. After launch in May of 2018, the InSight project moved from development to its operational phase.
