I really dislike the where is Webb graphic. It's layed out like a map, but it's a timeline not a map. It's basically 1/2 way distance wise to l2, but it's mapped at less than 1/4 of the way there.

What's neat is the Moon on the timeline is at day 2.5, and the Moon orbits at just a smidge under 250,000mi(4% off from actual). L2 is just a smidge under 1,000,000mi(7% off from actual). This means that Day 10 is the location of L2 in relative space. So, rough distance, JWST is almost at the Day 5 mark. ETA: The number of days being "10", counts as metric, right?

Wonder if the covers rolled back to just short of triggering the closing latches, what can happen if they aren't secured? |

Quote HistoryOriginally Posted By junker46: Travel or learn anything useful about distant stars/planets. I don't think there is any real benefit to all this. There is a lot to see but very little if any practicality deep space exploration. We may guess at compositions of other stars and planets; learn more about gravitational fields or time or whatever. And of course the 'spin-off' technologies, and keeping several thousands educated and employed. But outside radio waves, I doubt mankind will reach other star patterns. We'd have a difficult time reaching Mars. Its like billions spent studying earthquakes and hurricanes. We may, at some point, learn very precise and predictable effects of them. But guess what? There is fuck-all to do anything about it. All you can do is learn to mitigate the damage caused. I know this is in contrast with 'Astronaut Heros' and 'muh NASA!' and 'Merica!. Just one of it's functions is to allow us to see what we cannot currently see due to red shift caused by the expansion of the universe. It has the potential to see "back in time". Another possibility is discovering what dark matter is. You know the mass we know exists in a 6 to 1 ratio of visible matter but is otherwise not visible? We are still at the infancy of space knowledge but it sounds like you have checked out and are done learning. Cool I guess.  |

 In order to successfully deploy both booms 107 actuators all had to function correctly, and it appears they have. I believe when the sun shield tore during testing a couple years back it was during the boom deployment stage, so getting past that without incident is a big relief |

Does NASA have wide angle POV cameras onboard to verify the unfolding process or do they just go by sensors. It would be cool if they have a couple of GoPro style POV cameras proving a feed to NASA that they may release at some point. |

With all the crap flying around at incredible speeds in space, it makes me wonder how confident they are about not having an object strike the shield. It probably wouldn't take something more than the size of a marble flying at 20kmph to hit near an anchor point of the film to completely wreck it.

Please explain something to me. I'm probably misunderstanding some fundamental point, and if I am, please enlighten me.
The Webb lets us see galaxies so distant their light has red-shifted into the otherwise invisible infrared spectrum. So they're saying that with the Webb they will be able to see "the beginning of the universe," the farthest galaxies, etc. But isn't it presumptuous to say that the infrared spectrum is the edge of it all, that "as far as we can see" is "as far as it goes"? How do they know it doesn't go "beyond the infrared"? Maybe when we reach the limits of the infrared, it goes a THOUSAND times further away than that, although of course it would be beyond any detectable light spectrum. Yet, they talk as if what they can see in infrared with the Webb is the end of it, there's nothing beyond that, they will see "all the way back to the beginning of the universe." It just seems presumptuous. Again, maybe I'm missing some point, but that's my question. Anybody? |

Again, maybe I'm missing some point, but that's my question. Anybody? Microwave and radio wavelengths are longer than the IR spectrum. Here’s a good illustration of the full electromagnetic spectrum and what range the JWST will be capable of detecting:  The oldest light we can detect is the cosmic microwave background radiation:  The Cosmic Microwave Background radiation, or CMB for short, is a faint glow of light that fills the universe, falling on Earth from every direction with nearly uniform intensity. It is the residual heat of creation--the afterglow of the big bang--streaming through space these last 14 billion years like the heat from a sun-warmed rock, reradiated at night. https://www.scientificamerican.com/article/what-is-the-cosmic-microw/ |
