If it's beforehand, wouldn't that just be enact the landing?

I feel the name Perseverance kinds of jinks the mission. How about "I got two days to operate" in Hebrew and then let it defy expectations.
/nothing can beat the GOAT Curiosity

I'm not sure, but I think that's a small scale die-cast replica of a Space Shuttle.

I thought buying Hot Wheels - and other similar diecast thingies - would be a good distraction from my other vices and in a couple years I ended up with more than I know what to do with so recently I made a list of just the ones I was really looking for.  I got it down to FOUR.  Thanks to subby, my list is up to five.  (I'm sure I would have eventually stumbled across it anyway.)

And if you look closely, you can tell that one of the shuttles cannot tell if it's supposed to be Discovery or Endeavour.  Just to be safe, Mattel slapped both names on it.

I'm just glad to be in before the Spirit Rover XKCD, that one always gives me a sad.

//JPL seems amazing, I would love my kid to end up there (at 9 years old he loved The Martian, and likes math so maybe there's hope?)

If you look on either side of it you can see Challenger and Columbia

I recall a cartoon by motorsport cartoonist Russell Brockbank showing a flabbergasted tycoon in an opulent office, seated behind a huge desk and in front of an ego wall of trophies and photos of winning racecars, facing a modest but triumphant gentleman clutching a set of blueprints.

The caption reads something like "so you claim OUR world championship-winning car infringes the patent on YOUR Wattel Superwheels 1:64-scale Monster Drag Racer"?

May I just say as someone that has worked on software for converting between them... unit systems are freaking hard. Maybe not as hard as accurate local time, but still bloody hard.

Forgive my ignorance but what exactly do you mean by that--
Like, you can never really know what time it is?
Serious question.

If you've got a sextant, a horizon (natural or artificial), and a clear sky, you can accurately determine local noon.  Comparing that to Coordinated Universal Time will give you your longitude, and the altitude of the sun above the horizon (along with the date) will give you your latitude.

It's more a question of translating current/historical times between jurisdictions than it is a measurement problem.

Jurisdictions of course are an artificial human construct and how they treat time is both arbitrary and not consistent over time.

For a complex but hilarious read, I'd suggest https://zachholman.com/talk/utc-is-en​o​ugh-for-everyone-right

The TLDR though is that economic synchronizing, geopolitical changes, daylight savings policy, leap seconds, calendar migrations and such all impact how any moment in time is represented at the location a person might be. So handling all of that accurately is actually a huge coordinated effort that more or less means maintaining a database of time related events for every location on the planet.

Naming it Perseverance is kind of like telling a dancer good luck before a performance. Thing will be dead within a week if it makes it to the ground in one piece.

And that article (review? dissertation? manifesto?) looks like a pretty entertaining read. Thanks

Mudd's woman: article (review? dissertation? manifesto?)


Good description. Kind of like a blog post that got crossed with textbook.

The fact that his further reading includes links to both Dan Carlin and The Internet Society's RFC for Standardization also kind of speak to how weird of a read it is.
