Previous years’ spending bills required the use of the SLS for Europa Clipper, even as NASA requested the flexibility to acquire a commercial launch vehicle.
A month after the passage of the bill, NASA directed the Europa Clipper project to halt all planning for launching the spacecraft on SLS and instead prepare to use a commercial vehicle.NASA, in its fiscal year 2021 budget request, argued that a commercial launch could save the agency “over $1.5 billion compared to using a Space Launch System rocket.†By contrast, a NASA Office of Inspector General report in 2019 concluded the cost difference could be less than $300 million, although that study estimated the cost of a Falcon Heavy launch at $450 million, more than twice the value of the contract awarded to SpaceX.
The Europa Clipper contract adds to a growing manifest of future Falcon Heavy missions for NASA, the Defense Department and commercial customers.
