Credit: NASA/JPL-Caltech NASA has decided to launch the multibillion-dollar Europa Clipper mission on a commercial heavy-lift rocket in October 2024, and not on the government-owned Space Launch System, officials said Wednesday. The decision ends a prolonged dilemma for NASA, which until last year was legally required to launch the Europa Clipper mission on the more expensive Space Launch System. The language passed in previous NASA appropriations bills directed NASA to launch the probe on the SLS rocket, but Congress relented in the fiscal year 2021 spending bill passed in December.
