Curiosity gets a software update that will speed its travels and better protect its wheels

Engineers this week completed a major software update on the Mars rover Curiosity that, among many other improvements, will allow it to travel more quickly across the rocky Martian surface but at the same time better protect its damaged wheels.
The team also wants to maintain the health of Curiosity’s aluminum wheels, which began showing signs of broken treads in 2013. When engineers realized that sharp rocks were chipping away at the treads, they came up with an algorithm to improve traction and reduce wheel wear by adjusting the rover’s speed depending on the rocks it’s rolling over.
The new software goes further by introducing two new mobility commands that reduce the amount of steering Curiosity needs to do while driving in an arc toward a specific waypoint. With less steering required, the team can reach the drive target quicker and decrease the wear that inherently comes with steering. “That ability was actually dreamed up during the Spirit and Opportunity days,” Denison said. “It was a ‘nice to have’ they decided not to implement.”
The software will also make it possible for Curiosity to travel more without the help of humans on Earth, which will also speed its travels up Mount Sharp, on ground that is getting increasingly rough, as shown in the mosaic above of navigation images from March 27th.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.

“…will allow it to travel more quickly across the rocket Martian surface…”
I’m sure you probably meant “rocky” Martian surface, right?
Ray Van Dune: Thank you. Fixed. As I get older I increasingly discover that what I meant to write has no relation to what my fingers type.
