Talk:Spacecraft bus (James Webb Space Telescope)

2016 Proposed merge with James Webb Space Telescope
This is just one component of the JWST IdreamofJeanie (talk) 16:22, 12 December 2016 (UTC)

Note: Relevant policies for this include: WP:CONSPLIT, WP:OVERLAP and Inclusion (non policy but useful). TheMagikCow (talk) 16:34, 12 December 2016 (UTC)


 * Support: Not worthy of its own article, but a notable inclusion on the JWT page. Per WP:CONSPLIT, I would say that this topic is not distinct, so does not merit an individual article. TheMagikCow (talk) 16:34, 12 December 2016 (UTC)
 * Commment This was created for the page when it was just a few sentences, on that day . Fotaun (talk) 12:50, 20 January 2017 (UTC)
 * Keep This proposal seemed to have gone stale, but I don't think this is a good merge. I would have just added this content to the main page then. It did not seem like a good fit and that page is quite packed as it is. Fotaun (talk) 12:50, 20 January 2017 (UTC)

How much power does the EPS produce?
The most basic spec for an Electrical Power Subsystem is the available power in Watts, yet this article never provides that number. And, it would be interesting to see how that number compares with the figures for the previous space telescopes. Perhaps even a graph?

404 Errors
Many of the sources contain only a weblink that is not available any longer. The whole article needs a redo, proper sourcing including the names of the website plus page titles, authors, dates etc. PDFs need to be treated as literature not as simple site links. Outdated links need to be updated or replaced by archive links.

Antenna/communications ref
"The communications dish which can point at Earth is attached to the bus.[15]:Fig 1 " does not seem a good ref here as it is just a figure annotation and not discussed. Is there a ref that discusses the communications that will say eg what angle the HGA can steer (if at all), what its diameter is, and how data downloads are scheduled relative to observations ? - Rod57 (talk) 10:50, 9 June 2021 (UTC)
 * In 2004 it was decided to stick with X-band and not bear the $40 M cost of changing to Ka-band. Would be interesting to have ref for the later change to ka-band. That ref says Ka-band might only need 35W transmitter rather than 50W. and that about 250 Gbits/day need to be sent, which is hard to send in 8 hours with X-band. - Rod57 (talk) 21:14, 13 October 2021 (UTC)

What processor chips used
Article mentions multiple processors, but does not list them or identify the chips used or and chip details like clock-freq, power, ips, or what memory (RAM/SSD) is in the bus. Is any of it radiation hardened ? - Rod57 (talk) 14:15, 20 August 2022 (UTC)
