Curiosity: 4844th day of the mission

@pomarede Where is Canadian Automobile Association when you need it?

@SCALETHEORY @pomarede The mission was designed to last about 700 days, but is now on day ~5000. Undoubtedly the wheels were made as light as they thought they could get away with, because every ounce matters in a rocket launch. If you make something lighter to save weight, it will necessarily be less durable. According to other comments, NASA decided the durability of the wheels wasn't as high as they were hoping and future rovers got thicker wheels, necessarily at the cost of weight.

@nazokiyoubinbou @pomarede every gram of weight is hideously expensive to thrust, so the thickness matters, alot. This has already lasted 10x what it needed to for the mission to be successful, so id say they designed it very well for durability, nothing lasts forever.

@raven667 @pomarede I mean, that's fair enough, but if it had been intended to last longer that would be a problem so easily solved.

If It had torn up more sooner it really would have been bad... The way it could potentially just rip through it seems like it could have failed just with a tiny bit of bad luck even perhaps on day one.

@pomarede When 4800 sols old you reach, look as good you will not.

@pomarede They should have got Schwalbe Marathons, I'm pretty sure they'd still be going strong

[kintarian@norcal.social]

@pomarede Better call AAA

[nazokiyoubinbou@urusai.social]

@Ann_Effes @pomarede What's the cost if the whole thing failed on day one?

@nazokiyoubinbou And if it was supposed to feed martian children they should have made it out of cheese. /s

Change the specifications of the mission, and any expert decision can be made to sound foolish. That's called "whataboutism."

[wronglang@bayes.club]

@nyrath @pomarede more like pessimistic about how long the darn things would keep trying to drive around!

[nazokiyoubinbou@urusai.social]

@grim_elsewhere @raven667 @pomarede How is it a "whataboutism" to say "what if the landscape had been even just a little bit rougher?" The landscape was not really fully known at the time it was landed.

Bear in mind that knowing it would hold up longer is only a valid argument for a time traveler.

@pomarede this is so sad!

[hoco@sfba.social]

@Kintarian @pomarede It's so far away.... It's gonna need AAAAAAAAAAAAAAAAAAAAA.

[scaletheory@mastodon.social]

@Ann_Effes @pomarede

Yeah yeah, got it, but this is still the best of the best? Wow, okay next excuse.
Seems a wheel from a lawnmower/shopping cart (made lighter with the most expensive metals/plastic) would last longer.
How about putting what was wasted in research for anti-magravity/ion/alternatives or just half/quarter/eighth of what CERN has spent.

Common sense, its societies new superpower. Rockets don't even make sense worried about weight.

@pomarede Our poor lonely fellow️

Soon you wonderful machine! Hopefully soon we’ll be there!

[faraiwe@mstdn.social]

@pomarede me too, little rover, me too...
