IMHO the article should briefly explain what part of the spectrum the telescope is looking at and what can be seen there. It is too technical right off, it needs a understandable introduction. 85.197.16.138 ( talk) 04:29, 14 May 2009 (UTC)
Only SPIRE and PACS have detector temperatures below 2K. HIFI has a detector temperature between 2 and 3K.
The image reflects the design forseen until 2001, i.e. a totally outdated mounting of the subreflector and the old service module design. It should be replaced by one of the current images from the ESA site. According to the Terms of Use this should be possible. —Preceding unsigned comment added by 81.173.179.240 ( talk) 12:59, 25 January 2009 (UTC)
This whole article is written in the future tense, as if it has not been updated since Hershcel started operating. The mismatch between tense and reality is nw even more acute now that Hershel is about to run out of liquid helium and cease operation.
So there is a lot more than just the image that is out of date. 64.134.239.71 ( talk) —Preceding undated comment added 23:24, 12 March 2013 (UTC)
What do you use as reference value when calculating dB's? 10^-12 ? —Preceding unsigned comment added by 94.209.25.26 ( talk) 20:05, 14 May 2009 (UTC)
The spectrometer has a resolution between 1000 and 5000 [clarification needed] and is ...
If this is a dimensionless unit there needs to be some explanation (a link to another article, perhaps), else it appears that a dimension is missing. This is not in my field, so I do not know the technical merits of the text, only that in reading it seemed a bit odd. - Leonard G. ( talk) 00:09, 16 May 2009 (UTC)
Hello, I have moved the "launch and orbit" § to the end of the article.
It seems to me more logical in the life of the satellite.
In addition, this § will have much more details in the near future when the satellite will be submited to manoeuvres to be put in its final Lissajous orbit.
Then, new § will logicaly appear : tests in orbit, activation of the payloads, and finally a very large paragraph with results of the experimenations (many years of very interesting informations, I hope.-- Friendly, aaaf-wiki ( talk) 04:53, 16 May 2009 (UTC)
It is implied by a couple sites (below) that the Hifi camera has not responded for about a month - however I can only see it reported from a few Dutch media (and don't really speak Dutch). Can anyone find enough confirmation to consider it verifiable?

Was there any consideration of a warm mission as WISE and Spitzer had after their coolant was exhausted ? - Rod57 ( talk) 16:27, 13 March 2021 (UTC)
After decommissioning (at SEL2?) it was just left to drift randomly away into a near-earth heliocentric orbit ? - Rod57 ( talk) 12:51, 7 July 2021 (UTC)
