This is the official r/space megathread for the deployment period of the James Webb Space Telescope. Now that deployment is complete, the rules for posting about Webb have been relaxed.
This megathread will run for the 29 day long deployment phase. Here's a link to the previous megathread, focused on the launch.
#Details
This morning, the joint NASA-ESA James Webb Space Telescope (J.W.S.T) had a perfect launch from French Guiana. Webb is a $10 billion behemoth, with a 6.5m wide primary mirror (compared to Hubble's 2.4m). Unlike Hubble, though, Webb is designed to study the universe in infrared light. And instead of going to low Earth orbit, Webb's on its way to L2 which is a point in space several times further away than the Moon is from Earth, all to shield the telescope's sensitive optics from the heat of the Sun, Moon and Earth. During this 29 day journey, the telescope will gradually unfold in a precise sequence of carefully planned deployments that must go exactly according to plan.
What will Webb find? Some key science goals are:
-
Image the very first stars and galaxies in the universe
-
Study the atmospheres of planets around other stars, looking for gases that may suggest the presence of life
-
Provide further insights into the nature of dark matter and dark energy
However, like any good scientific experiment, we don't really know what we might find!. Webb's first science targets can be found on this website.

Maybe a dumb question
I understand that the lagrange point itself changes position while the earth travels around the sun
But why does JAmes Webb needs to orbit the lagrange point itself? Couldnt it just stay motionless relatively to the point?
I just learned about Lagrange points today thanks to the James Webb telescope and wondering if this mechanic is possible in KSP and if so how complex is it to position?
o7 CMDRs, hope all of you are having a great Christmas. I just want to share my first experience at a storm cloud. Now I've been all over the galaxy, and seen many things. I seldom come across NSP, and they're usually Proto-Lagrange clouds anyway. But I noticed that in the codex, there has been a storm cloud and anomaly located in a nearby system.
I drop in, and wow. The rumbles of thunder, my ship rocking back and forth as it gets struck by lightning, that right there has to have been one of the best experiences I've ever had in E:D. So atmospheric, the sound and graphics design is perfect.
If you haven't already, I highly recommend you guys visit one to see for yourself.
See you in the black
In older versions I saw a lot of Lagrange points in systems, but now I'm seeing most systems have 1 or none, since most systems don't have planets. If I choose the one to transit from I can't go anywhere because there are no Lagrange points. Why? What's changed?
Also there's an option to stabilise Lagrange points that some fleets have, and not the usual gate building ships. What's this do?
Freshman college student so pardon if the question is dumb. Iβm currently taking an intermediate microeconomics class and we just introduced Lagrange multipliers. However, it was in a slightly different fashion to the method in my multivariable calc class, so I wanted to ask if there was a reason for this difference. In Economics they introduced the lagrangian = U(X,Y) - lamba * (I - PxX - PxY) and to optimize they set partial derivatives with respect to X, Y and lamba equal to 0. In my math class, we would optimize this by setting gradient of U equal to lamba * gradient of the constraint. Both of these methods lead to the same result: MUx/Px = MUy/Py, but I wanted to ask if there was any difference in the approaches and simply why economics would present it in a different way.
Using an unstable Lagrange point gives a service life to the JWST as it will eventually run out of fuel. Surely using a stable Lagrange point would extend its usable lifespan?
I played Rise of Kingdoms for a few years and I'm looking for something fresh yet similar to RoK. The one thing I enjoy about RoK is real time battles with freedom of movement and open field fighting, and it seems most games don't have this mechanic. Do any of these games allow this? What are some pros and cons for each? Which one do you enjoy?
So it's been years since I've done partial and total derivation, and I can't afford Mathematica. I've already asked on Stackexchange to no avail and i'd like to get through this problem rather quickly since this is just the start of a larger problem I'm working on.
Any help would be greatly appreciated.
Title: Lagrange
Format: Short
Genre: Sci-Fi
Pages: 9
Logline: Alone in an escape pod stranded between the Moon and the Earth, the mission's only survivor must find a way back home before she runs out of air and power.
Feedback/Concerns; This is the first draft of a short I'll be filming early next year. Since I am self-financing and building the ship in my garage, the "contained" nature of the story is a true budgetary and logistic limit. So please try to keep comments with production realities in mind.
Looking to make a career pivot but $ ISN'T my main motivation. I've researched them and the top story was title white collar sweat shop. Looking for some advice from previous/ current employees. Thanks in advance, y'all
EDIT: Thanks everyone! I think I'll still interview with them to keep my interview skills sharp. This is probably the universe telling me to go back to grad school, hahaha. This time I'll actually study and network and join some clubs or something. Networking is SO flipping underated.
Saw some videos of how the telescope will be doing a mini orbit at the L2 point while it goes around the sun. Do not understand what it will be orbiting exactly? How does it orbit nothing?
