  1. Fine, Bezos has a vehicle that can land cars on the Moon, but how long until there's a monetary return on that? It seems like Blue will be burning through Jeff's cash for some time to come. Obligatory: "Hey, Mr Bezos - wanna come outside and see my eco-bus and its friendly toilet?"

  2. Then you'll really, really love Starship

  3. Regarding Dear Moon / Elon Time - could it fly by 2029?

  4. So since red blood cells aren't really alive to begin with, then what was the criteria for calling them 'dead', or saying that they die at an increased rate in space?

  5. @1:32 - regarding landing on Mars and taking off on Mars, that wouldn't happen with a 33-engine booster, but only with the 6-engine Starship stage. So special precautions for the OLM are warranted, since it alone is handling the full launch stack with SuperHeavy on the bottom.

  6. When are you going to make this in KSP, Manley?

  7. So on the one hand, Musk once tweeted that the tank must be the hull, to be volumetrically efficient and avoid having "box inside of box". But on the other hand, the tank is made of composite and the hull is made of steel, so isn't it back to "(composite) box inside of (steel) box"?

  8.  @scottmanley  wow - shouldn't there at least be a liner, rather than just a pressure vessel made of welds? It seems weird - and full of seams.

  9.  @scottmanley  can welds really do the job, though? What evidence is there to support this?

  10.  @रेनी10  - yes, that's true - although this is mission Luna 25 for Russian space scientists. They've been there many times already.

  11. Why can't they use electromechanical actuators instead of the pneumatics/hydraulics? Wouldn't those be more reliable?

  12. SS-520? So a Soviet naming convention then?

  13. ​ @Christina Aubin - is he? SpaceX shares aren't publicly traded. So is he among the private investors who own stakes in SpaceX?

  14. ​ @Mike - I don't understand your phrase "earn the right" - what right? And who has earned it? What does it mean to earn the right to go to space? Are we saying that only some people deserve to go to space? Who are these people who deserve to? Who deserves to, and who doesn't? Did Charles Lindbergh earn the right to fly across the Atlantic? Did Elon Musk earn the right to build rockets, even though he never earned any formal aerospace degree from any academic institution? Does he have the right to build tunnels without any civil engineering designation? Or the right to build neural implants without a medical degree? We can all attempt things while making use of the expertise of others.

  15. ​ @Ben Katz - hah, I dunno about Scott, but I know I'm jealous of Jared. Although I'll admit that I don't have the guts to be the guinea pig for Starship's first crewed flight. Maybe it's because all those Starship RUDs are seared into my memory. I think I wouldn't mind flying on Dragon, since the forces don't go above 3 G's.

  16. Wow - so does Virgin Galactic have any paying customers lined up for orbital launches?

  17. Moon's too empty, not overcrowded

  18. Didn't one of the senior SpaceX guys state that the 20km Starship flight will take another 4 months to happen?

  19. If the Phosphine was from a biological source, like tiny anaerobic bacteria floating high enough in the atmosphere, would there be a particular altitude or atmospheric layer/strata that would be more favorable to the sustenance of such bacteria?

  20. Only 4 roentgens - I'm told that's the equivalent of a chest x-ray, comrades

  21. I wonder whether the Chandrayaan-3 mission will be able to send its propulsion stage to hit a crater and stir up a debris cloud for analysis, like how LCROSS did.

  22. How long could this latest debris cloud stay up there?

  23.  Feiner Fug  sounds like a job for computational/combinatorial chemistry, to figure out how some geological process could create Phosphine. Are there any other ways to distinguish where the Phosphine came from? Such as fluctuation in the Phosphine levels, periodicity, timing, etc?

  24. If the Phosphine was from a biological source, like tiny anaerobic bacteria floating high enough in the atmosphere, would there be a particular altitude or atmospheric layer/strata that would be more favorable to the sustenance of such bacteria?

  25.  PANTIME  I know they don't drop rocket stages on villages and towns
