More wear found on Curiosity’s wheels
Routine inspections of Curiosity’s wheels has found new damage on the rover’s left middle wheel.
None of this is unexpected. Nor is it a serious problem. They expected the wheels to wear out over time, though I must say that it seems to me that Curiosity’s wheels, in use now for about five years, do not seem to be doing as well as Opportunity’s, working on Mars for more than a dozen years. Opportunity was only supposed to last for 90 days. Curiosity was designed to last years. Yet, it seems that Curiosity’s wheels are wearing out faster than Opportunity’s.

My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID 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. Every one of those 2020 conclusions has turned out right.
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.

I think the difficulties with simulating Mars’ reduced gravity on Earth plays a part in this. The Mars 2020 rover will show how NASA has solved the wheel and drill problems. But then again, it will land in a different landscape and could encounter other challenges. Previously not seen small hard sharp rocks covering the entire landscape would be a setback even for the new reinforced rover wheels.
It’s a really nice thing to have roads.
Not so nice to have rover wheels made out of crushed beer cans.
Space exploration is hard. How many other countries have active rovers on planets?
We do our best and learn from the results.
