Episode 189
Impact craters can expose the subsurface in a way that no rover is equipped to do. So the biggest crater accessible to Perseverance in many months looked like a good exploration target, until it disappeared from view.
There seems to be something sticking out from the distant ridge in the horizon at 3.20, left of the upper end of the red arrow. Any ideas what that might be?
Spirit, Opportunity, and recently Ginny… Thank you for your service and for sparking so many people's interest in Mars, NASA, and engineering/rovers! ♥️ 🫡
Anyways, this episode reminds me of Star Wars EP 2, where Obi-Wan is trying to find a planet that wasn't showing up in the database… 😅
The difference between a vertical view and a side view is often surprising. Too bad Ingenuity was not able to continue long enough to reach some of these interesting features where the view from above would be helpful. From a field geology perspective, though, the crater is too eroded to have useful outcrops, so I understand why Perseverance moved on without looking closer.
Hidden in plain sight. Interesting impactful and thought provoking observations.
The view (2:10) has grey and red colored surface, while Perseverance view (2:22) doesn't have much grey tones. Wondering how much lighting angle may have effected an orbital crater reveal. Perhaps a time-lapse, or a flicker-cam view of two images hours apart would reveal changes in shadows, and thus better perspective of the crater topology?
Curious, if the crater has almost vanished after 10 years due to 'weathering', then why are river courses still visible since they apparently dried up billions of years ago?
Could it be that since Mars is smaller than Earth, "things are hidden sooner"? It is possible that the cavity of the crater that you mention is there but its study is not of interest, or that it is difficult to access due to sand or landslides, or that Percy "has not stretched his neck properly." 🙂
The only one who transmits the authentic news of the other world in the format of people. Your calm voice has become part of the landscape of another planet for humans. When the next amazing movie about the red planet appears, your voice should be taken into account for a more realistic look
😎👍

I feel that in these parts (VA) it is the vegetation that cover up and fill up any ground shapes rather quickly… Thx Mars Guy.
This phenomenon sort of reminds me of LIDAR imagery on earth that sometimes reveals buried shapes or structures. The Carolina Bays come to mind.
Actually, it's possible to discern the top of the rim of the crater just below the big rock.
On the back looking view you can just make out the crater.
Your confidence in identifying an invisible feature is commendable.
Some 🕳️ in One, NASA Engineer's must be avid ⛳🏌️😉

Thinking about Opportunity reminded me – I haven’t heard about what Curiosity is doing in a while.

Probably some Martian guy covered it 👽
Neat
Greatly appreciated
Could you turn off the mouse clicks in your presentation? Distracting, and irritating.
Happy Sunday!
interesting

what is in the sky at 2:29?
Pico crater
Why not stop and explore it anyway?

Thanks!
red rover red rover send mars guy right over
