Marveling at the world

Lots of Martian rocks and landscapes, looking all too familiar, but don't be fooled by that: Mars is an inhospitable toxic planet. Let's not mistake fiction for reality.

I like dirt and rocks, but I Am Not A Geologist (IANAG).

Yeah, I noticed you didn't hint at the location but I'm currently neck deep into some work I'm doing so I may let it pass (the previous one over Valles Marineris desperately called for some Mars Trilogy toponyms, but I passed that too).

I expect to spend some time in plotting Perseverance's next drive, if LA announces a new one, but apparently the rover is having a Memorial Day BBQ right now, on the MMRTG grill 🙃

@andrealuck
One thing I noticed is that Phobos moves right to left in the animation, which would make it east to west, assuming north is up. In reality Phobos rises in the west and sets in the east, which could suggest that this animation is upside down? 🤔 However one should also consider the spacecraft's motion relative to Phobos in those ~34 seconds, so it's not certain it's upside down.

North up helps with the maps 🤓

Amidst the sand waves.

#Perseverance's MastcamZ is ~1.9m above ground level. The tilt of the image may be indicative of (but is not equal to) the inclination of the ground where the rover was located when it captured the image.

Another ~25m and #Perseverance will be out of t̵h̵e̵ ̵w̵o̵o̵d̵s̵ the regolith ripple field and in the mostly flat part of the Neretva Vallis riverbed.

Tosol's ~17m drive brought the rover right where those ripples start. The dark area is where #Ingenuity will be hidden from our remote prying eyes.

It was about time after all those months in the middle of rocky nowhere 😜 The loose regolith ahead seems rather shallow, with bedrock showing here and there (IANAG™), and the rover drivers did a pretty good job bringing it down here on a steady and safe pace. Two more drives and that's it, I think.

#Ingenuity is seen here sticking its solar panel above the sandy waves of #ValinorHills in this image from Sol 1152 received today. While the solar panel of the #MarsHelicopter may still be visible from the rover at its present location on Sol 1159, it will soon disappear when #Perseverance clears the ripples it's facing on its way northwest to Bright Angel.

Another ~13m drive, -2m in elevation change for , along the easternmost path I mentioned yesterday. Maybe those ripples aren't that difficult to cross after all.

Those shortcuts I thought I found through the regolith ripples look pretty impassable from this angle; but maybe they'll look better as the rover comes closer to them.

Instead of putting up "angry" performances wrt student protests and ICC's issuance of an arrest warrant for Netanyahu, Biden had better listen to what the Irish Prime Minister had to say when Ireland announced the recognition of the State of Palestine (along with and ).

That's how politicians, who actually respect the intelligence of the people whom they serve, deal with political issues, and how they honor their homeland's love for freedom.

I'm afraid I'm not well versed in inter-government dynamics in the countries involved, but whatever they be, the end result is significant and probably puts things in motion. Undoubtedly politicians would make as best a use of the opportunity as they could.

Listening to the words spoken by the Irish trio, I got the impression that they bore real meaning, especially when contrasted to Biden's "angry" and hypocritical preaching about "the right thing" to do.

@65dBnoise@mastodon.social avatar

@jesusmargar @Lassielmr
Biden is of partial Irish descent so the contrast between the Taoiseach mentioning his county's past and Biden's theatrics couldn't be starker. I take heed of the words of an Irish who recalls his country's suffering when offering a path to peace (what a contrast to Israel's offering only wars in the name of the Holocaust), but I find Biden's words hypocritical, offering no solution to the problems his government's Middle East policy is creating.

New location for on Sol 1156, after a rather short ~16m drive downhill, which brought the rover 2m lower, to RMC 52.2750. There is now a ~10m remaining vertical distance to be covered to the bottom of the riverbank and onto the ancient riverbed of Neretva Vallis.

The maps were made with using 's data, imagery and DTMs.

No, ICC's request for an arrest warrant for Netanyahu is not outrageous. What's outrageous is your defending of a corrupt extreme-right politician's genocidal war.

And good luck trying to explain to young voters how your idea about justice and "law and order" differs from that of the clown who's in court these days in NY.

@jesusmargar
The same theatrical "angry" response, peppered with some old-man's preaching about his idea of morality, when mass graves are discovered and tens of thousands of children have been murdered with weapons he supplied in abundance, while civilians starve and suffer. Some "morality" to preach others about...

Not only not convincing on moral grounds, but very hypocritical and immoral.
