NASA's Europa Clipper has been liberated from the Space Launch System

Almost unnoticed, tucked into the 2021 fiscal NASA funding section of the recently passed omnibus spending bill, is a provision that would seem to liberate the upcoming Europa Clipper mission from the Space Launch System (SLS).

According to Space News, the mandate that the Europa Clipper mission be launched on an SLS remains in place only if the behind-schedule and overpriced heavy lift rocket is available and if concerns about hardware compatibility between the probe and the launcher are resolved. Otherwise, NASA is free to search for commercial alternatives to get the Europa Clipper to Jupiter's ice-shrouded moon.

[....] The Europa Clipper being mandated to fly on an SLS to begin with was the result of an unseemly side of congressional budget politics. The space probe was championed by former Rep. John Culberson (R-Texas), who at the time was the chair of the House appropriations subcommittee that funds NASA. In order to get support for the Europa Clipper, Culberson added the SLS mandate, which garnered support from Sen. Richard Shelby ( R-Ala.), chair of the Senate Appropriations Committee. Shelby's state contains a number of aerospace contractors involved in developing the SLS.

[....] As Ars Technica points out, launching the Europa Clipper on a SpaceX Falcon Heavy saves the mission $1.5 billion. An advantage of using the SLS has been that it allows for a direct path to Jupiter without the time-consuming planetary flyby maneuvers that previous missions to the outer planets have required. The Falcon Heavy alone would not be able to get the Europa Clipper to Jupiter space directly, though it might be able to if equipped with a powerful Centaur kick stage.

Both the economics and physics of getting to Europa change if SpaceX's Starship, currently under development in Boca Chica, Texas, becomes available to launch the Europa Clipper in the mid-2020s. The Starship is meant to fulfill SpaceX's CEO Elon Musk's dreams of settling Mars. But the massive reusable rocket would be available for other things, presumably including sending probes to the outer planets.

[....] The SLS has since been a lead weight on America's space ambitions. The SLS slated to launch the Artemis 1 uncrewed mission around the moon is currently stuck in a ground-based "green run" series of tests. The SLS is currently using up a great deal of the money allocated to NASA's Artemis program. The first flight is scheduled for November 2021 at the earliest.

Perhaps Boeing could rescue the SLS by introducing a new SLS-MAX product.
