@DanielleFong EDS is a close second to TDS.

@ChrisDMarshall @LunarCitizens Do they have the cross range to bring it back to the launch site in a single orbit? They may have to wait several orbits.

@eulersnightmare @DrPhiltill @A_J_Higgins It would be a good thing for BTC.

Wouldn't you rather I gave the money to you than to the bartender?

[Not-So-OK Boomer @Rand_Simberg]

The NFL should consider just offering PPV per game for people who just follow one non-local team. I'd pay $30. It would beat going to a sports bar, which is my only current option absent Sunday ticket.

Incredible as it may seem, this one building will likely produce as much value as a member of the G20.

And that's just a single facet of the megacorp that will one day (soon?) rise from the amalgamation of SpaceX and Tesla.

Who knows, maybe NVIDIA will end up in there too.

16.5 years ago, one-sixth of a century, I was a prospective student here at the Berkeley School of Physics. Now it's Sunday and the doors are locked. No one's around. Are we going to make it?

Maybe the centaurs are working from home.

@StephenFleming It depends on their purpose. Equatorial isn't feasible until we build equatorial launch and landing platforms, but it's the best orbit if you don't need to see the planet.

Just which aspirations of Putin are there that we should be helping him achieve? I hope someone's going to ask him.

[Caolan @CaolanReports]

Jared Kushner says peace should be a “win-win” deal that helps Putin achieve his “aspirations.”

@JeffGreason While it's an overgeneralization, physicists tend to be better at telling you why something won't work than they are at figuring out how to make it work.

Wendell Barry has passed, at age 92. He was virulently opposed to space settlements. Here is an exchange he had on the topic with Steward Brand in the 1970s: https://t.co/br68PNC7gG

The comments on this are appropriately brutal.

[Men's Health Mag @MensHealthMag]

Everyone's favorite science expert Bill Nye gives us a tour of his gym & fridge.

[Not-So-OK Boomer @Rand_Simberg]

Hmmm...probably Michael Mann. He owes me half a million bucks after his lawsuit against me.

[Rand Simberg @Simberg_Space]

Your occasional reminder that physics PhDs are not engineers. The physics PhDs told us that we couldn't do missile defense.

[SafeNotAnOption @SafeNotAnOption]

@Robotbeat I suspect there remains lingering skepticism that they can make it work.

[SafeNotAnOption @SafeNotAnOption]

@peterrhague That's funny, but Leibniz did come up with a superior notation, because it was easily applicable to independent variables other than time.

[SafeNotAnOption @SafeNotAnOption]

@Robotbeat NASA could have demonstrated it in the 90s after the broke DC-X, but instead they gave X-33 to the wrong company, then used it as an excuse to say that it proved that reusability was impossible.

@MadTreeMan @enL3X1 @JamesRaxz Seat belts don't cost that much, but not clear how many lives ABS and airbags save.
