Europa Clipper to be delayed because of SLS bottleneck
Because Boeing will be unable to provide an SLS rocket in time for the planned 2024 launch of Europa Clipper, once the probe is completed NASA will be forced to put it in storage.
The problem is that Congress has mandated that the Jupiter probe be launched on SLS, but has only funded the first two Artemis launches to the Moon. Boeing will also need at least three years to build it, meaning that even if the money from Congress appeared today, it would likely not be ready for its ’24 launch date.
In terms of rocket science, right now, Europa Clipper can launch on a commercial vehicle, like SpaceX’s Falcon Heavy or United Launch Alliance’s Delta-IV Heavy rocket, although the mission would then need a longer cruise time to reach its destination.
But in terms of the law, NASA’s hands are tied.
“Because of that, we’re planning to build the Europa Clipper and then put it into storage, because we’re not going to have an SLS rocket available until 2025,” Bridenstine said. “That’s the current plan. I don’t think that’s the right plan, but we’re going to follow the law.”
Though the common sense thing for Congress to do would be to release NASA from this mandate and allow the agency to pick the launch rocket, do not expect that to happen. Congress wants SLS because of all the pork it produces. They will not allow NASA to reduce its reliance on SLS one iota, if they can. Unless pressured publicly (which I think is NASA’s goal with this announcement), Congress will let Europa Clipper sit in a warehouse for years, at a cost of between $36 to $60 million per year, waiting for SLS.
