Episode 115
Collecting rock samples for return to Earth is a primary objective for the Perseverance rover. So there was cause for concern when the last two attempts failed. Here’s what happened on the third attempt.
Third time's a charm. Always has been. It's really amazing what NASA has been doing, but I'm still stomped at how this will be retrieved. They plan to send another rover that picks all of these up and in the mean time they will just be laying on the ground, or at least a portion of them. One dust devil and it's buried or moved into a different location. The latter being more dangerous as there's no way to find them then unless you drive in outward circles while brushing all the sand away….
How many unused sample tubes remain in the Perseverance sampling mission? Will Perseverance and Ingenuity continue exploring uncharted territory following the end of the sampling mission, or will both return to their initial landing area to act as a landing port for the future UPS delivery truck mission to pick up the samples?
That's great news that they've got a sample. Interesting, slightly gung ho approach, but sometimes you just have to go for it! Thank you for the update!
Once again exceptionally good at communicating complex operations and the issues associated with each step in a concise understandable way. Really great stuff.
Has it even been explained how these rocks are going to be returned to Earth? Because it is a human going to collect them, then might as well just dig and rest on Mars and save a few hundred million dollars.
Interesting article in NASA Mars 2020 blog written by Denise Buckner, Student at the University of Florida: "Persevering Across the Upper Fan in Search of Record-Keeping Rocks".
About conglomerates as sedimentary rocks, plus many other interesting things, Buckner says:
"Certain types of iron-bearing minerals display magnetic properties, and when a magnetic field is applied to these minerals, the direction of magnetization can shift, serving as a record of the event. The conglomerate test is used to determine whether a rock experienced a “remagnetization” event after it formed."
The above has reminded me that not only many birds, and marine animals are oriented by the earth's magnetic field. Man, from time immemorial, has also developed magnetic orientation instruments.
Many vessels are built with ferromagnetic materials. The terrestrial magnetic field is capable of inducing magnetism or polarizing, from a needle or small ferromagnetic strips, to a steel vessel docked in the same pier for a long time, what's more, the latter will need a magnetic compass adjuster, since we know that the acquired magnetism will cause a deviation in the on-board compass.
Very interesting! Thank you.

Amazing, roughneck software does the job!

Awesome boyo !!
Thanks
I can't say that I haven't taken samples while precariously perched.
Well done, as always!
A nail biter for sure… Thanks Mars Guy!
Hmmm I don't understand the last line in the video
Rite Mars Dude, pesky humans interfering @ the end how very dare they! TFS, GB 🙂
I can't wait until we start going back there to get the samples. Now that should make for some great MG vids. Cheers MG. 😎
That was riveting, l mean drilling.
Thanks Dr Ruff. 🔴
".. without human intervention.." wonder if Mars will first be colonized by AI-aided robots setting everything up before we get there?
That's great news that they've got a sample. Interesting, slightly gung ho approach, but sometimes you just have to go for it! Thank you for the update!
Wow, the action on Mars is moving on at pace. Thanks for keeping us posted Mars Guy.n
All things taken into account, Perseverance/Ingenuity have been truly successful.
Sounds to me like an intern was at the wheel 😂
Love your content, thanks! Such good editing.
Clearly some mad lad behind the wheel this time. Drifted into the opposite direction and YOLO'd a drilling operation. 😀
Mmm roggs

Wouldn’t using the same tube for all three samples invalidate it? There is residue from all three locations.
Phew, that was a rather risqué episode.
Great story telling, complete with a Mars style cliff hanger!
I didn't really understand the ending of this video? Why did the team choose not to fully seal the sample? In case they had to try coring again?
Thanks mars guy! Appreciate all your hard work and updates… have you ever thought about doing an interview with Fraser Cain? 👍👍👍
The rover didn’t need to return to Earth, since it was already here. They just had to get it from whatever remote place on earth they were doing this.
I wonder what the big rush was all about.
Has it even been explained how these rocks are going to be returned to Earth? Because it is a human going to collect them, then might as well just dig and rest on Mars and save a few hundred million dollars.
Ah that's nothing you should see the ship they take to wipe down the rovers panels with, it uses magneto-hydrodynamics to fly to Mars easily. 👏😂
Coring bit looks red hot. Must have drilled it really fast!
<jk> whole planet is red.
Beautiful landscape images e.g. at 0:24. And I would like to see 1:14 come true (astronauts on the surface of Mars).
BOWIE!!
Wham, bam, thank you ma'am?
… Besides rock, is there a plan to return Martian atmosphere?
What will happen to the upload of photos on the NASA Mars 2020 mission science blog? It is not usual to spend 4 sols without uploading photos.
Thank you these videos are really easy to understand and not complex like other channels ❤
