Totally! It's a bit of a gray zone between LA and Sac. Sac has the worst driving/traffic because everyone is doing their own thing / own form of chaotic driving. LA driving is madness, but comparatively it kind of works because at least everyone is on the same wavelength of crazy.

Mars 2020 Perseverance Rover SHERLOC Instrument Isolation System - NASA Technical Reports Server (NTRS) The NASA Jet Propulsion Laboratory (JPL) successfully landed the Mars 2020 Perseverance Rover at Jezero Crater on the Martian surface. Perseverance’s main mission objective is to cache Martian rock an...

Ah, found a paper on just this! These isolators shield SHERLOC from the percussion of the drill, compensate for the extreme thermal range, and compliance during installation (among other things). Paper found in the link therein ntrs.nasa.gov/citations/20...

Any MechE rover heads out there know what went into the design of these mechanical interfaces to SHERLOC on Perserverance? It's like a gas strut with two degrees of compliance at both ends. Is this just a combination of thermal expansion, shock, assembly compliance? Why solid thin-fin vs a joint?

Looking east towards Lone Pine. Probably around the 3800 meter mark. I think that is Consultation Lake (it's been a minute!). This one is so blown out it has its own vignette.

Towers of cold icy granite in Cirque of the Towers. I recall feeling rather underdressed in a way only a teenager's planning could manage.

I found a grip of negatives of photos I shot as a teenager. It was this weird camera that shot wide on 35mm. The exposures are a bonkers 14x37mm. Lots of knicks in the negatives. The lens wasn't great and there was no shutter speed control. I think this is heading into the Cirque of the Towers.

Chotiner has really been doing the work the last few years. Even when the situation is terrible (as with this one), reading this type of sober interview/accounting feels almost like a salve in comparison to the general media/information environment.

My review of Caves of Qud, based solely on phrases my partner mutters to themself while playing, is that it's effectively a Pliny the Elder simulator. They just hissed, "I believe honey has something to do with healing, but I don't know what it is" and then starting inspecting a pig
