NASA decides against launching Europa Clipper using the Space Launch System Shane McGlaun - Feb 13, 2021, 11:25am CST One of the places in our solar system that scientists have hopes of harboring extraterrestrial life is Europa, one of the moons of Jupiter. To learn more about the icy moon, NASA is gearing up to launch the Europa Clipper mission. Originally, that mission was to be launched aboard the Space Launch System known as SLS. However, a few days ago, NASA confirmed during a presentation meeting of its Outer Planets Assessment Group that leaders of the Europa Clipper project decided to consider only commercial launch vehicles for the mission. That means the end of support for launch aboard the SLS.
