Perseverance bit off more than it could chew

[@tinkertailor7385]

I can guarantee that if they dropped that coring bit in the dirt, that mushroom would fall right out and laugh at them.

Hey Perseverance, You've got something stuck between your teeth.... No problems, I have 5 more sets I can use.

[@AtkinsAtelier]

Ive been watching since the beginning and wanted to actually come out and say how much I appreciate your videos every week. Solid serious information and high quality production always ending on a funny quip. Thank you Mars guy!!

[@MarsGuy]

So glad you appreciate this content. Nice to have such longtime viewers.

I keep all my old drill bits too for the day I rig up something to sharpen them again... Thx Mars Guy!

[@MarsGuy]

Ha ha!

[@jimcabezola3051]

Mahalo for this! I guess I never paid enough attention to realise that Perseverance had SPARE drill bits and could replace them! It's great that I DID NOT design it, isn't it? I would not have thought about bringing spare bits! Aloha!

[@MarsGuy]

Ha, well, not everyone thinks like an engineer!

[@rjung_ch]

Hi Mars Guys, love your Sunday compilations. Thanks for yet another interesting one. Cheers 👍💪✌

[@MarsGuy]

Glad you're still watching.

[@flannelshirtdad]

Reminds me of an old joke: How many engineers does it take to unscrew a coring bit?😂

[@Sheaker]

Thank You Mars Guy! So many spare core bits! So much mass! Fortunately they correctly predicted it will be useful.

[@MarsGuy]

Yeah, that extra mass is worth it to ensure all the samples can be acquired.

[@apriladams7119]

Thank you, Mars Guy! I love how I learn something from every video. You're the best for updates!

Thanks again. Happy to have appreciative viewers.

Hell I was ignorant of Sherloc with Watson! Ingenious naming!!!!!!

[@stefanschneider3681]

Thx as always ☺! Talking of geology: Last night I was glued to the Laptop when the earth opened up again in Iceland with no warning, spiting out millions and millions of tons of fresh lava. How would that look in a hundred million or a billion of years? Especially if untouched by what an ISS astronaut once called "All that shit going on within our atmosphere we call LIFE"? Just wondering ...

[@justyce_yt]

Iceland doesn't sound too icy right now

[@28th_St_Air]

So you’re saying it bit off more than it could chew. 🥁

[@hopelessnerd6677]

Ace Ventura: "Do I have something in my teeth?"

[@wordreet]

Disappointing that the core got stuck, since the cutting "tips" will describe a circle smaller than the internal dimension. Presumably a bunch of sandy granules somehow went up alongside the sample and jammed it.

[@Sherwoody]

Now if Mars Guy could just tap it a bit with his geology hammer, it would drop right out.

[@MarsGuy]

Ha ha!

[@rickc4317]

Excellent report and explanation once again. Thanks, Mars Guy.

[@MarsGuy]

Thanks again for watching.

[@siberx4]

If they could find a pointy enough rock, they could try poking it with the middle of the coring bit to see if it dislodges the sample.

[@JKTCGMV13]

I had known the tubes were eccentric but I had no idea why until this video 😮

[@MarsGuy]

Yeah, really clever design.

[@polocarthaigh893]

The next lander needs robotic arms and spare parts, wings for instance, for it's friends.

[@MarsGuy]

Well, at least this one's got plenty of spare drill bits.

[@1kreature]

I think I'd try a very short coring operation and then without doing a new shearing-operation I'd try dislodge or ingesting the fragment again.

[@coralie9469]

You just want to reach in there and knock it out, just like wanting to fix that lens cover, it's just amazing what all they can do from so far away! Thanks Mr Mars, another great video, you never disappoint!

[@MarsGuy]

Yeah, I know the feeling! And thanks.

[@drguenther]

thanx for that episode again. 2 cores and one hole made me thinking and wondering for a while. Didn't remember the stuck core :-)

[@omnijack]

It would be wonderful if the stuck rock brought in some accidental science when recovered.

[@Don.Challenger]

That tool carousel should have a station with a prong and a compressed Martian air air port that can clear/blow through the coring bits (of course with the default spring actuated prong's position being retracted).

[@GWNorth-db8vn]

Springs and air won't do it. It's wedged and needs a shock to get it free, then it will fall out. You'd normally use a brass punch and give it a few taps.

[@MrGaborseres]

Thanks 👍

[@bazpearce9993]

If it's got that much sample in there they should be keeping it.

[@tommyfred6180]

yah they should drop it off when the do the next sample collection dump.

[@gordonwallin2368]

Very nice videos. Cheers from the Pacific West Coast of Canada.

[@MarsGuy]

Thanks from AZ!

[@ericfielding2540]

I expect that we will bring the samples back to Earth, but it will take longer than originally planned. We will see later this month what the reviews of Mars Sample Return mission say.

Wow Mr. Mars Guy! ❤️ You know how to make a girl stay awake 😉

[@MarsGuy]

[@beyerdr]

So cool. At the beginning i was thinking man it would have been cool.if it could change out clogged or broken bits and then i find out at the end it can! These rovers are fascinating feats of engineering and always exceed expectations!

[@L.LGodwill]

Lesson learned , And always forward

[@armandomercado2248]

Good update. ⛏️

[@MarsGuy]

Thanks 👍

[@johngardiner5206]

Presumably they tried just using it to cut, at least, a short core? If it Jams up worse, there's no loss anyway.

[@crowguy506]

The next rover needs a maintenance arm. Hopefully Starship will basically get rid of the payload cap.

[@Allan_aka_RocKITEman]

_Perseverance_ was equipped with _6-bit_ technology...😉

[@Rmm1722]

Good work 💯😎

[@Yezpahr]

I say drop it, mark the location, pick it up with the other dropped modules when it's pickup-time.

[@colinantink9094]

Percy is falling apart lol. I say this in jest because of the vast HUGE selection of tools it has. If you have 100 things. More stuff will fail then if you have 1 thing. But. I feel the pain when my hole saws get jammed up.

[@rougehawk]

Did Curiosity ever have similar problems?

[@DarkVoidIII]

They need to design and ship a service rover whose job is to perform maintenance on these rovers. Something simple like pulling a stuck core sample shouldn't be that hard for it to do.

[@glencrandall7051]

Thanks. Have a great day.🙂🙂

[@MarsGuy]

Thank you too.

[@ts-900]

I was hoping that they would stick with it a bit longer.

[@billykershaw2781]

Great vid.

[@MarsGuy]

Thanks

[@Don.Challenger]

Can the dropped coring bit be picked up like the sampling container drops will be, how much dust will they be expected to have covering them. (When the rover is parking/idle do the folks at Perseverance HQ document the 'passing tumbleweeds' and other activity/accumulations with motion capture, periodic time lapse or bracketing (stop/start) pictures?)

[@caevans61]

True!

[@puddintame7794]

I wonder why it wasn't replaced in 2022 then?

[@GWNorth-db8vn]

It was. It's been sitting in the rack and they just got around to giving it another try. The first version of this rover is still running 11 years later, and this one might last long enough to wear out the supply of bits it has.

[@MarsGuy]

Thanks, good answer.

[@drillthrallable]

Hello, Mars Guy! I really enjoy your videos. Thanks for not bombarding us with background music. Much appreciated. Anyway, quick question. If Mars only got as far as algae for life, would it show up in the rocks in some form that Perseverance could detect, see?

[@MarsGuy]

Thanks, glad you appreciate this content. It's possible that algae could be preserved as highly degraded organic matter preserved in clay-rich mudstones, which might be detected by some instruments on Perseverance.

[@worldofrandometry6912]

Such a 'boring' video 😁. An amazing machine.

[@MarsGuy]

Ha ha!

[@markusrobinson3858]

Why did the engineers wait two years to drop it in the dirt? Sure seems like nothing changed over two years except perhaps that half of it fell out over those two years if im reading the image correctly. If half did fall out, presumably because normal bouncing around of Perseverance, why not wait longer (since they were prepared to wait two years for this development)? Seems like there is more to this story than meets the eye.

[@GodmanchesterGoblin]

Yes. You might give it a couple of months, drive around a bit, use other tools to shake things up, but if they have spare tools you want to start using them before other parts of the vehicle become less reliable and might then restrict further investigation.

[@willierants5880]

Why not just try to use it to drill into another rock? The subsequent drilling action might very well help to crush the stuck fragment thus allowing it to come out. What is there to lose if they are going to just stop using it altogether? Seems obvious.

[@ExopMan]

Why didn't they swap the bit out years ago? Instead they stopped coring for this whole time??

[@GWNorth-db8vn]

They did swap it and they didn't stop coring. The transport costs make this the most expensive drill bit in human history, and they're taking another try at saving it.

[@middleagedwhitebloke]

👍🏻. Thank you Mars Guy.

[@MarsGuy]

Rite Mars Dude, Who's yeah Daddy cough Boss! How much for one of those bits? Stay safe n well out there. TFS, GB :)

[@josephd.5524]

If they have half a dozen replacement tools, why wait a year to swap out? Your rover has a limited lifespan, use your tools!

[@antibrevity]

You misunderstood. They DID swap it out. They got the tool back out in order to try cleaning it again.

[@MarsGuy]

Correct

[@josephd.5524]

@@antibrevity Aaaah, I see. Thank you.

[@President_NotSure]

Perseverance says take care of Earth instead

[@antibrevity]

I agree with taking care of Earth as we are presently doing nothing except to document our own destruction. However, Apollo was a tremendously beneficial economic program for industrialized humans; space exploration is not a relevant cost to humanity or Earth. People might debate whether industrialism has itself been good for us our our finite planet, but please do not claim the planetary exploration is a waste of resources when humans are DESIGNED to be explorers. Our inherent wonder and curiosity are some of our best traits. Driving pickup trucks to and from desk and retail jobs is a *huge* waste of resources that kills our descendants, but sending rovers and probes to study the Universe is God's work, regardless of what spirituality you have. NASA has 8% of the budget it did during Apollo, yet American taxpayers waste billions on inefficient transportation and lawn care and trillions on lost wars over the past few decades. Millions of people having green, manicured lawns is harming Earth *far* more than if we increased space spending by 10X or more. Spend *more* on science and exploration and less on suicidal destruction and murderous warfare. We can afford to explore the Universe, but should never pretend that becoming multi-planetary is a salvation from Earth's destruction. That's pessimistic escapism, not hope

[@dragonmares59110]

Quite a lot of defects and issue with perseverance. I feel like they did not do enough tests in the end.

[@GodmanchesterGoblin]

So, how do you test a remote-controlled vehicle and its tools in a Martian environment for three years to see what may go wrong? You can only test so many times before you have to try out a thing for real. For some of the faults that have happened, even the reduced gravity on Mars might affect how they developed, making sustained laboratory testing difficult. This stuff IS rocket science.

[@antibrevity]

Perseverance has performed just fine. NOTHING will work perfectly forever on another planet with a harsh environment. Things WILL break and they will continue to break the longer the rover goes on. That does not mean it has defects.

[@GodmanchesterGoblin]

@@antibrevity Exactly.
