Admittedly NASA’s plan for Mars Sample Return was like throwing a long bomb downfield and hoping like hell someone would be there to catch it.
(But oh it’s infinitely frustrating to have those carefully curated, painstakingly collected tubes of precious Mars dirt w no clear path to return them!)

The Wall Street Journal just illustrated the core argument of my book: a system rigged to reward capital over labor is one in which even full-time work no longer secures the most basic material needs.
This is the economic order that produces the "working homeless."

Our “president “ is such a cruel lying bastard.
This is what Hess said: “It brings up mixed emotions to represent the US right now. I think it’s a little hard. There’s obviously a lot going on that I’m not the biggest fan of. Just because I wear the flag doesn't mean I represent everything that's going on in the US.”

This especially applies to Star Trek Picard, where the United Federation of Planets exists to promote peace and mutual benefit, wherease in the Q induced alternate future we had a polluted Federation of Earth, which was an Earth First tyrrany. Sound familiar?

Go to bed, Galileo!

GALILEO'S WIFE:
Dinner, Galileo!
GALILEO [Looking through telescope]:
Just need to check my orbits

[Galileo's friend the POPE is now standing next to Galileo, who is still looking through his telescope]
THE POPE: Come to church, Galileo!
GALILEO: Not now...
6. FALLING OUT WITH FRIENDS
GALILEO: [Showing The Pope the book he's working on) I'm just working on my book challenging the Bible's view of the Universe
7. BEING ARRESTED BY THE INQUISITION
[GALILEO is being dragged out of the room, hands outstretched to his telescope. He is calling to it]:
GALILEO: Telescooope

[GALILEO sitting in front of his telescope, now with bars over the windows]
GALILEO: Ah, crap.

ICE at the polls! Bannon is basically yelling “fire” in a crowded theater here. His objective is to cause chaos (and suppress votes on the left). And it’s already working.
This threat works on multiple levels and doesn’t have to be “real” to serve its purpose.
Let me explain & offer some advice.

If you're rich you get a tax cut, if you're not you have to work longer and harder. Populism! bsky.app/profile/atru...
Dr Oz: "If we could get the average American to start working a year earlier, right out of high school, or a year later -- not retire -- or work better during their lifetime because they're healthy, it would generate about $3 trillion to the US economy. That would more than remove the debt."
