Here's the text without having to execute arbitrary code from twitter. --- Update: according to #EUSST's latest estimates using data from its surveillance radars, the close approach between #space objects SL-8 R/B & OPS 6182 expected by tomorrow will have a miss distance under 10m and a Scaled Probability of Collision over 20%! +updates to follow soon See the below plot for the conjunction plane at Time of Close Approach (TCA) #EUSST #spacedebris #space https://pbs.twimg.com/media/EycvaPZWQAMXjV2?format=png&name=large https://pbs.twimg.com/media/EycvaPZWQAMXjV2?format=png&name=... Update: #EUSST simulations indicate that the potential collision between the two #space objects would generate more than 4 million fragments. This plot shows the Delta-V distribution of the whole cloud of fragments #spacedebris https://pbs.twimg.com/media/EyhGxpjXMAE-pmM?format=jpg&name=small https://pbs.twimg.com/media/EyhGxpjXMAE-pmM?format=jpg&name=... More than 400 of the fragments generated by the potential collision would be larger than 20cm. Gabbard diagram shows the extent of orbital regimes that these simulated fragments would reach. #EUSST continues monitoring the probability of collision. Stay tuned for more updates. https://pbs.twimg.com/media/EyhQ_InWYAI5V5a?format=jpg&name=small https://pbs.twimg.com/media/EyhQ_InWYAI5V5a?format=jpg&name=... Latest update: according to #EUSST the close approach between #space objects SL-8 R/B and OPS 6182 remains stable in geometry and in Scaled Probability of Collision. Miss distance would be ~21m and Scaled PoC over 20%. This should be the last estimate until TCA. https://pbs.twimg.com/media/EyiBCnsXEAAgrCu?format=jpg&name=small https://pbs.twimg.com/media/EyiBCnsXEAAgrCu?format=jpg&name=...

Are you able to translate this to layman's terms? Should I find a bunker?

  I assume the fear of this sort of thing is the potential for causing Kessler Syndrome.

  No, there's not a risk of space debris.

  You don't need to find a bunker, but there's a risk that we'll soon have a lot more 'space debris' in orbit. If a collision happens, it'll basically turn the colliding satellites into scattershot, leading to a higher likelyhood of other smaller collisions with other satellites (less spectacular but could still disable even more satellite). Not sure how likely the latter scenario is, but it could get very costly if it did happen.

  You're running Javascript. It's sandboxed, which is why I have it enabled by default, but often the javascript in a website is made to spy on you and your behaviour. It's not on your side but on the side of the people who made the website. Personally I'm ok when something like discord breaks as it contains real time updates. But twitter just displays a bunch of text and pictues in a non real time manner. Even video can be played back without any js.

    You can put a video on a page without js, but a lot of your customers would have a poor experience.

      Apparently ≈2.24% of global users are using a browser that doesn't fully support HTML5 video: https://caniuse.com/video https://caniuse.com/video

        That's one hell of a lot of people.
  - airza 6y ago
    That's not arbitrary code in the security sense though. It's the very narrow range of things which are permitted to run in a javascript sandbox (more or less "things javascript can do in a web browser context, minus the extremely small chance someone is trying to drop a JS 0day on you using this link")

Replace `twitter.com` with `nitter.eu`: https://nitter.eu/EU_SST/status/1380120766071635968 https://nitter.eu/EU_SST/status/1380120766071635968

  I was pretty excited when I found out about nitter. After some months I realized that every nitter mirror only stays up for a few weeks before it becomes so popular it's throttled most of the time (like nitter.net). Also, it's 17:41 UTC now... the events of this post should be occuring now. Or not occuring.
  - dpifke 6y ago
    It's really easy to run a private instance of your own: https://github.com/zedeus/nitter https://github.com/zedeus/nitter Mine isn't publicly accessible so never gets throttled.
    - andrepd 6y ago
      I have one for invidious, probably should spin one for nitter as well :p

Please omit flamebait from your comments here. You started a totally off-topic argument about Javascript which got upvoted to the top of the thread, gaining mass and choking out interesting discussion. Not cool. https://news.ycombinator.com/newsguidelines.html https://news.ycombinator.com/newsguidelines.html

  While I agree with hiding the parent commit for the flamebait, that also hid my on-topic layman's explanation of what's happening :( [Er… commit = comment… TGIF, leaving it in for fun ;D]

    Good point. I've detached https://news.ycombinator.com/item?id=26752335 https://news.ycombinator.com/item?id=26752335, which was the return to ontopicness.
