    Observed magnitudes of Qianfan spacecraft range from 4 when they are near zenith to 8 when low in the sky.

    Since this is the first run of the Qianfan satellite constellation, the most appropriate comparison would be to Starlink’s original satellites. As you can see below, the notion that China’s satellites are “significantly brighter than those of Western systems” is a inaccurate.

    A 2022 paper on Starlink Original, VisorSat and Post-VisorSat models: https://arxiv.org/pdf/2210.17268

    The Original spacecrafts have a relatively flat phase function, so they are comparatively bright over a wide range of phase angle. […] the characteristic magnitudes are: 4.7 (Original) […]

    A 2024 paper on Starlink newer Direct-to-Cell satellites: https://arxiv.org/abs/2407.03092

    The mean apparent magnitude of Starlink Mini Direct-To-Cell (DTC) satellites is 4.62 while the mean of magnitudes adjusted to a uniform distance of 1000 km is 5.50.

    Clearly, even the newest Starlink satellites are well above the magnitude 7 limit astronomers recommend for satellite brightness.

    “Communism works the same way, except the party leaders are the ones on top,” you think to yourself as the crimson Poverty Line flashes upwards across your field of view. “Capitalism is the only system that works.” The wind is rushing hard in your ears now; the bottom of the Money Pit is coming up fast. “Besides, they worked hard to swim in the Money Pool, they deser–.” Splat.





  • Again, perfectly fair. Before I was a communist, I rejected Marxist concepts as well. I’ve spent over two decades reading and listening to arguments for and against all sort of political, social and economic ideas. I’ve identified with centrism, liberalism, libertarianism, social democracy and other ideologies. Today, I consider myself to be a Marxist/socialist/communist not because it’s just the latest thing I’ve hit upon, but because it’s what’s made the most sense to me. When I use Marxist words and ideas, I don’t do so because I’m a Marxist; I’m a Marxist because those words and ideas have helped me to make the most sense of the world. And I’m certainly not demanding, or even asking, you do become a Marxist, I’m just asking you to consider what makes the most sense.

  • Joseph Sisko’s restaurant is his personal property, not his private property since it is not a money-making venture. Since money, and capitalism, do not exist in the Federation, there is no private property in any form. Furthermore, given Star Trek’s egalitarian/utopian vision of the future, no one is going to take Joseph Sisko’s restaurant – the laws of the United Earth government (which has direct jurisdiction over Earth) exist (imo) to protect people’s personal property, not take it away.
