SpaceX waits in the wings as NASA risks maiming Jupiter probe to pinch pennies
SpaceX and its Falcon Heavy rocket continue to wait in the wings as NASA risks maiming its ‘Europa Clipper’ Jupiter probe by pinching the wrong pennies.
For the second time, NASA has performed “continuation/termination reviews†of three of the Europa Clipper spacecraft’s scientific instruments after budget overruns on the order of no more than a few tens of millions of dollars. Thankfully, no instruments were canceled, unlike the “ICEMAG†magnetometer that was functionally killed last year. Still, a NASA program scientist casually noted that the space agency would tolerate launching without one of two cameras and would offer no more funding to a mass spectrometer instrument (MASPEX), raising the risk of instrument failure during the challenging mission.
For any scientific spacecraft or rover, the instruments carried along are effectively the entire reason for their existence: if those instruments are faulty (or even removed before launch), the mission is effectively rendered pointless. Further, due to the sheer complexity and challenges posed by the act of getting to the destination and surviving after arrival, the actual instruments most scientific spacecraft carry represent a tiny fraction of the overall mission cost and mass. It’s not easy to readily imagine a better way to signal inept program management than by singularly focusing on that tiny, lifeblood-esque portion of a spacecraft’s budget. Undeterred, that is exactly what NASA appears to be doing with Europa Clipper – penny-wise, perhaps, but undoubtedly pound-foolish.
Notably, for the first time, the House legislation frees the Europa Clipper mission from the SLS rocket. It says the agency should use one "if available." No one at NASA presently expects an SLS will be available for the Clipper launch, so that's big.
It’s not always true that only a small portion of an exploratory spacecraft’s budget is spent on scientific instruments but it absolutely is when it comes to Europa Clipper. Originally hoped to cost as little as $2 billion in 2013, Europa Clipper’s budget allocation has ballooned to $4.5 billion over the life of the program. Of that $4.5 billion, as little as $110M was dedicated to nine scientific instruments assigned to the spacecraft – a ratio of ~41:1. Even if instrument cost ballooned by 100% to ~$220 million, it would still be a measly 20:1. The space environment around Jupiter is admittedly one of the most challenging in the Solar System, warranting some imbalance, but either ratio is still exceptionally bad as far as most exploratory missions go.
