- After you get a second/third COVID vaccine, people have symptoms because it is part of the immune response. Why doesn't that happen when you're actually exposed to COVID after vaccination? Why doesn't that immune response cause symptoms?
- How does the immune system determine which anti-bodies are needed to deal with a virus infection?
- Did the solar panel on the JWST deploy a little earlier than planned? Will that cause problems?
- How many of the single-point failures of the James Webb Space Telescope are already behind us?
- Since JWST will be so far from earth, will we be able to get better distance measurements through parallax from it?
- How long will it take for the Webb to set up and start sending us images?

| How does the immune system determine which anti-bodies are needed to deal with a virus infection? Posted: 26 Dec 2021 07:20 AM PST I guess it tries a lot of different anti-bodies and some will work but how does it tell which are working? Does it count blocked/broken viruses somehow?

| Did the solar panel on the JWST deploy a little earlier than planned? Will that cause problems? Posted: 25 Dec 2021 07:47 AM PST I was watching the live stream, and just as the JWST separated from the last stage and the video was showing it drift away, the solar array deployed. It was pretty clearly a few minutes earlier than expected, and there seemed to be some sudden tension in the audio among the flight control team. Was the deployment early? And, will that cause problems down the line? [link] [comments] |
| How many of the single-point failures of the James Webb Space Telescope are already behind us? Posted: 25 Dec 2021 07:27 AM PST I assume there was a bunch of single point failures that could have occured at the time of launch, now there will be a somewhat "easier" period, and there will be another bunch when JWST arrives at the Lagrange point and opens up. At the time of writing this post JWST is ~4.5% of the way to the Lagrange point 2. [link] [comments] |
| Posted: 25 Dec 2021 08:13 AM PST JWST is going to be 1 million miles from earth, much further than ground based or orbiting telescopes. Are scientists planning to use the additional distance to be able to look for shifts in relative positions of objects due to parallax to help us refine distance measurements? Typically we get astronomical parallax measurements from the changing position of the earth through its orbit, but that takes time (6 months). Maybe JWST will help measure distance to short-lived phenomenon? I've heard lots of discussion of how JWST will help image the farthest/oldest objects, but not anything concerning if it can help refine our measurements of closer objects based on it being offset from earth.
