I hope we get that greenhouse on Mars sooner rather than later. Seems more important than Twitter.
- TEP_Kim_Il_Sung 4y agoFreeze peach always seems unimportant until you lose it. Good thing that goes hand in hand with economic improvement, based on historical evidence, and make greenhouses on Mars more likely.
- AlexandrB 4y agoIf our free speech rights depend on the whims of billionaire media owners we don't have those rights in any meaningful sense. I don't think that Twitter changing hands moved the needle one way or the other.
- TEP_Kim_Il_Sung 4y agoTwitter is just one, now fully exposed, symptom of a larger problem, which will be easier to deal with now that more people are watching.
- throwawaylinux 4y agoIt definitely moved the needle as you can see from the wailing and gnashing of teeth by a lot of the billionaire owned politicians, bureaucrats, institutions, and legacy media corporate "journalists". It's funny how angrily and desperately they insist that nothing really changed and everything is a "nothing-burger", but they're gaslighting you as usual. Speech and public opinion is still under the control of billionaires, and Musk is not likely to be particularly less greedy, self-serving, or egomaniacal as Murdoch or Soros or Bezos, but he is not in lock step with them. The enemy of my enemy is... quite possibly still my enemy, but it's beautiful to watch them fight one another. And if it can distract them from starting new wars or stealing more money and rights from people for just one minute, that's a wonderful bonus.

- c54 4y agoPeople have high hopes that Musk is some kind of principled arbiter but it's wishful thinking. https://www.cnn.com/2022/12/14/tech/elonjet-twitter-suspended/index.html https://www.cnn.com/2022/12/14/tech/elonjet-twitter-suspende...
- ericbarrett 4y agoGonna have to figure out how to deal with relativistic iron nuclei: https://pubmed.ncbi.nlm.nih.gov/11540033/ https://pubmed.ncbi.nlm.nih.gov/11540033/
- JumpCrisscross 4y ago> relativistic iron nuclei The Martian atmosphere is 1/166th the density of Earth's [1]. At the ISS's altitude, it's something like a trillionth. [1] https://en.wikipedia.org/wiki/Atmosphere_of_Mars https://en.wikipedia.org/wiki/Atmosphere_of_Mars
- idlewords 4y agoThe Martian atmosphere does not provide meaningful shielding against heavy ion radiation unless you're way down in the Hellas basin (where no one particularly wants to land). You reduce the flux by half compared to deep space just by having a big rock blocking half of the sky, but you'll still get all the cancer sooner than later.
- ericbarrett 4y agoA little napkin math says the columnar mass of the Martian atmosphere is 18 g/cm^2, versus 10g / cm^2 of aluminum shielding discussed in the paper. So being on the Martian surface would probably give you something like 1/10 (atmosphere + planetary mass + environment suit) the heavy ion radiation exposure of deep space. You'd need to be pretty deep underground most of the time (no windows, at least) to be safe for the duration of a reasonable visit. I'll pass!
- idlewords 4y agoThe napkin math falls short a bit because the heavy ions that absorb in the atmosphere will create a shower of secondary radiation that reaches the surface. Similarly, heavy ions that hit the surface will create secondary radiation from rock. This factor is why partial shielding in a spacecraft can give the crew a bigger absorbed dose than having no shielding at all.
- stronglikedan 4y agoThe Twitter takeover solved a real, current problem. Those are always more important than future problems.
- tasty_freeze 4y ago> a real, current problem. Those are always more important than future problems. You mean like addressing climate change, vs spending trillions trying to terraform a planet to make it barely habitable.
- rglover 4y agoMaintaining free speech will allow people to discuss and shed light on actual—not heavily manufactured—issues like the climate change movement being used as a distraction while banks and corporations implement natural asset corporations.

- kmonsen 4y agoThere is no evidence there is more free speech on Twitter after the Elon takeover. It's just different people being banned and for more arbitrary reasons.
- tagami 4y agoOff-world crop production can benefit life here on the Homeworld. We are working on that with our ExoLab missions. Our 10th mission is currently on the ISS looking at legumes for protein and vitamins like thiamine. https://magnitude.io/exolab-10 https://magnitude.io/exolab-10
- enkid 4y agoNo offense, but how? It just seems way more economical to grow plants in the environment they were evolved for.
- genocidicbunny 4y agoSeems it would be useful to quantify what that environment specifically is, maybe find some ways to improve it such that the plants are hardier or have better yields.
- nashashmi 4y agoWhy do people think this is even possible? CO2 is heavy stuff. All it will do is just fall back to the surface. Maybe methane will be better or even better will be O3 ozone. But methane does not last. And I’m not sure how to get ozone in the planet. Also, we hardly understand life on earth. Do we really think we can get life on mars for long periods of time?
- foobarbecue 4y agoMaybe they meant an actual greenhouse, not a greenhouse effect.
- Tepix 4y agoI was referring to the greenhouse that Elon Musk planned to launch to Mars that led him to found SpaceX.
- nashashmi 4y agoyeah. I realized that after someone else posted the same. I was referring to another crazy idea: Nuke the CO2 ice caps for a greenhouse effect on the entire planet.

- Tepix 4y agoYes. Most people think it wouldn't work.
- Taek 4y agoWhat Elon does with his time and money is his own business. What are you doing to help humanity get to Mars beyond scolding the person who is arguably the greatest single contributer to humans in space of the past 20 years?
- Teever 4y agoyou may want to consider why you're taking OPs comment about Elon Musk personally.
- moloch-hai 4y agoI don't want humanity on Mars. On Earth is bad enough. But we won't be going to Mars, help or no. Starship and Superheavy (Can and Kicker, by my lights) are woefully inadequate to the task.
