October 21, 20214 yr We shouldn't underestimate how important this mission is. 50 deployments, 178 release mechanisms. All have to work perfectly. Thousands of people, entire careers and all comes down to the launch. No second chances. The largest telescope ever put in space. One million miles from Earth. Edited October 21, 20214 yr by martin-w
October 22, 20214 yr Moderator This is exciting. Hope abounds that it will be fully successful! 😎 Fr. Bill AOPA Member: 07141481 AARP Member: 3209010556 Avsim Board of Directors | Avsim Forums Moderator
October 22, 20214 yr I'm praying this goes well. The James Webb Space Telescope will enable us to see and discover things like never before. I also like the collaboration between NASA, the ESA, and the CSA. We can do great things by working together and combining our resources.

October 22, 20214 yr Those Lagrange points are very interesting, because (contrary to popular opinion) they are not locations where the gravitational force of Earth and Sun are the same. However, they are balancing points, which means that the telescope will have to expend minimal amounts of fuel to keep it in position. It will be at the L2 Lagrange point, which is approximately 1.5 million kms from Earth on the opposite side to the Sun.

October 22, 20214 yr There goes more flying time because of something fascinating from Martin. I had not even heard of this. When I think of how Hubble changed how we think of the universe, I can't wait for this. I will admit a chuckle at the mention of Ariane, though, here on AVSIM. A lot of memories in this place.

Dave Yep, we'll actually be able to analyse the atmospheres of planets which is astonishing. improved infrared resolution and sensitivity over Hubble, and will enable a broad range of investigations across the fields of astronomy and cosmology, including observing some of the most distant events and objects in the universe, such as the formation of the first galaxies, and detailed atmospheric characterization of potentially habitable exoplanets. https://en.wikipedia.org/wiki/James_Webb_Space_Telescope The countdown... https://www.jwst.nasa.gov/content/webbLaunch/countdown.html

It will be at the L2 Lagrange point, which is approximately 1.5 million kms from Earth on the opposite side to the Sun. 1.2 million kilometres is astounding. Will only take 30 days to get there though. It sounds like the unfolding of the mirror and sun shield occurs within the first two weeks of the journey. There will be no second chances like we had with Hubble, no chance to fly a mission to fix dodgy optics. Fascinating that the solar wind will put enough pressure on the sun shield to move it around, so they have to have "trim tabs". I must say I am concerned, so complex, so much has to go right, but if successful it will be an incredible technological achievement. Of course I will have some "mega cat points" ready if they're successful. Here's ten for their achievements and dedication so far. 😺 X10 Edited October 22, 20214 yr by martin-w

There's always a sunset happening somewhere in the world that somebody is enjoying.

The solar sail is an idea that's been around for a very long time. In fact NASA are launching a mission in 2022 to test such a thing. You would be surprised what sort of velocities can be achieved with solar sails. Especially if a laser is used to boost the velocity. Max speed of a solar sail is something like 10% of the speed of light. Constant light pressure is very useful. It would have to be a lot bigger than the sail in DS9 though. 😁
