- xtiansimon 5y agoGreat vidy. Total pop-science neophyte here. I found it very very interesting to hear about the work required of the “flight dynamics” team to keep the telescope in its orbit. Wondering how this project stacks up against other man-made orbiting bodies in this regard. Is there a set-it-and-forget it to Webb range of complexity story here?
- 8bitsrule 5y agoWow. The 6-month-long orbit around L2 is twice the size of the Moon-Earth orbit. Sure it's 4 times as far away. But still, with the Earth rotating, the comms calculations for these guys must be messy: [https://eyes.nasa.gov/dsn/dsn.html https://eyes.nasa.gov/dsn/dsn.html Deep Space Network]
