Curiosity Blog, Sols 4954–4960: Celebrating Our Rover Engineers Past and Present

Written by Lucy Thompson, Senior Research Scientist, University of New Brunswick, Canada Earth planning date: Friday, July 27, 2026 As an APXS uplink lead and strategic planner, I have the privilege of working with the rover engineers most. The institutional report frames the development in practical terms and ties it to the broader mission or observing effort.

The significance lies in physics only takes a result seriously when the measurement chain remains robust under scrutiny. Experimental particle physics and precision metrology both operate in regimes where the signal sits far below the background noise, and where systematic uncertainties can mimic new physics if not controlled rigorously. The history of the field contains numerous anomalies that generated theoretical excitement before better data showed them to be artifacts, and it also contains genuine discoveries that were initially dismissed as noise. The difference is almost always resolved by independent replication with different instruments and different systematics.

The team managed to find rock targets of interest (x5), which the rover engineers were able to safely place the arm on and brush so that we could analyze them with APXS and MAHLI. Despite unexpected damage to the wheels early in the mission and getting a little bogged down in some soil/sand just as we started to climb Mount Sharp, the engineers have.

Of course, the engineers were able to accommodate our desires, with the first stop crossed off in Monday’s plan, and the drive that is being planned this weekend taking us toward. This required completely reconfiguring how we drill after a motor failed back in 2016, with extensive behind-the-scenes work at JPL for nearly a year and a half before we resumed.

The broader interest lies as much in the method as in the headline number, because a durable measurement procedure can travel farther than a single result. When experimental physicists develop a technique that achieves new sensitivity or controls a previously uncharacterized systematic, that methodological contribution persists even if the specific measurement is later revised. This is one reason why precision physics experiments often generate long-term value that is not immediately visible in the original publication.

Because the account originates with NASA News Releases, it functions best as a primary institutional report that is close to the data and operations, not as independent scientific validation. Institutional communications are produced by organizations with legitimate interests in presenting their work in a favorable light, which does not make them unreliable but does make them partial. Details that complicate the narrative, including instrument limitations, unexpected failures and results below projections, tend to be minimized relative to progress messages. Technical documentation and peer-reviewed publications, where they exist, provide the complementary layer that institutional releases cannot substitute.

The next step is more measurement, tighter systematic control and scrutiny from groups whose experimental setups are genuinely independent. In experimental particle physics and precision metrology, the threshold for a discovery claim is a five-sigma excess surviving multiple analyses; an intriguing signal at lower significance is a reason to run more experiments, not a reason to revise the textbooks. Next-generation experiments currently under construction or commissioning will revisit several of the open questions that give the current result its context.
