  1. https://blogs.nasa.gov/webb/2022/02/11/photons-received-webb-sees-its-first-star-18-times/
  2. There is at least one cooler for MIRI https://sci.esa.int/web/jwst/-/46831-cryocooler-for-miri This video explain how this cooler works
  3. Maybe a Blue Dot 2.0... not looking to our current home... but to our next!
  4. Yeah yeah... perhaps I was just a little... overcautious with all of this. It's a already risky mission, losing redudance pre-launch knowing how much redundant stuff already saved a lot of mission or launching a possible flawed spacecraft seemed a little too much. But in the end, as both of you said, it was deemed not worth repairing the sensor
  5. Yeah... maybe... or let's risk throwing billions and decades away... I know I know, it would work "just fine" with two last mirror, just some loss in "apperture" and some aberrations to be compensated... But still... I would not be ok given green light to a flawed equipment of this importance, but maybe that's just me... I really trust their decision, but I don't know... it irks me EDIT: looks like they are moving fine, already 4,5 out of the 12,5mm for both of them
  6. So... according with the lastest Scott Manley video, the two mirrors that aren't in position yet are flawled... each motor has a couple sensor, one in each motor isn't working, there is a work around, but they laft these two for last... Even worst, they knew it before launch EDIT: They knew since the vacuum chamber test, they just thought it to be much work to do... no words
  7. I did not expected to be this much, I thought they would be much closer to final position... Maybe some small alignment due to rocket vibration or assembly tolerance, but only that
  8. Man... on her launch reaction video, I wish the she had watched until separation and the deployment of solar panels... I imagine what was her reaction to the view o JWST and if she would be worried about the early deployment
  9. Instrument Radiator Deployed Only two manjor deployments left to go! Is it safe to say that JWST is now functional? Even without the primary fully opened it will be able to cool down, gather light and process images, just with a smaller area (assuming everything else works)
