A Big Rocket

This sentence in the second paragraph of the Introduction: "Launched aboard a big rocketTitan IVB/Centaur on October 15, 1997, Cassini was active in space for more than 19 years, with 13 years spent orbiting Saturn, studying the planet and its system after entering orbit on July 1, 2004." could use some work. Some spacing corrections and I'm not sure that the term "a big rocket" is really encyclopedic.

Telemetry incorrect/incomplete

I was the Cassini ground processing telemetry engineer from the start (1990) until 2012 when I retired. The telemetry section is misleading and incomplete. Only the AACS and CDS subsystems used mini-packets. There are many more measurements than stated. There are many more subsystems creating packets than stated. It is all much more complex than stated. These few paragraphs were written entirely from the AACS subsystem point of view, why?

Probably because whoever wrote it didn't have all the relevant information. Please update the information in the article and add some links to the relevant docs! - Parejkoj (talk) 23:30, 12 May 2021 (UTC)

Farewell Photo posthumous (?) date

How can the Farewell photo (see last section of the article) be dated "21 November 2017", when Cassini had by then been destroyed for more than two months? Maybe the mosaic was composed later (in November?), but the original photos included in the mosaic surely cannot have been made later than September? Should not then the Farewell picture, as giving an overview of the situation in September, be dated September 2017? Hans van Deukeren (talk)

The November date looks like the date of the press release of the image. The image itself was taken on September 13. Specifically, 2017-256 13:05 to 15:35, Spacecraft Event Time, although we can't use that in the article. The exact time is from internal project documents and not citable. If no one objects, I'll change the date in the caption to September 13, 2017. And I think I'll also add the Enceladus setting image (last Cassini image of Enceladus) which was taken immediately after the Farewell image. Fcrary (talk) 02:09, 7 August 2021 (UTC)

Changing lead sentence from using the words "intentionally destroy" to "scuttle"

In one of the final sentences in the lead paragraph, there is the passage, " Template:Tq " . I propose we change the "intentionally destroy" - to scuttle, which is just a more precise description. I will be bold and make the edit at some point, unless I get some push back here on the talk page. MaximusEditor (talk) 18:51, 19 October 2022 (UTC)

Is the term "scuttle" used outside a naval context? Cassini didn't open any valves to let water in so it would sink into the sea... - Parejkoj (talk) 03:47, 20 October 2022 (UTC)

Not more precise, even used outside maritime, it infers, an opening (door, hatch, ect...). - FlightTime (open channel) 04:04, 20 October 2022 (UTC)
