This article is about a robotic space mission to Jupiter. This article is about the mission; there is a separate article about the spacecraft itself.

Very much coming in as a non-expert here, but it looks like a cracking article and at least gives me the illusion that I can understand what is going on.

* {{Green|October 18, 1989 by}}: comma after ''1989''.

* {{green|gravitational assist flybys}}: should this be ''gravitationally assisted flybys'', as the first two words modify the third? I see no hits on Google Books for this precise phrasing.
*:It seems that "gravity assist flyby" is the correct scientific term [https://science.nasa.gov/learn/basics-of-space-flight/primer/], so standardised on that.

* {{green|Jupiter's atmospheric composition and ammonia clouds were recorded. Io's volcanism and plasma interactions with Jupiter's atmosphere were also recorded}}: any way to avoid the slightly clunky repetition of ''were recorded''?

* Suggest linking "encounter", as it has a more specific meaning in this context than its everyday loose one.
*: Added a link to the Wiktionary entry (which I just created): "The period of a space mission during which it carries out its data-gathering objectives".
* {{green|There was also concern about the effects of radiation on spacecraft components, '''which would be '''better understood after Pioneer 10 and Pioneer 11 had conducted their flybys. '''These indicated''' that the effects were less severe than feared}}: the tenses are a bit confusing here. How much time has passed between the two sentences? I'd suggest something in the middle to the effect of "these took place on [date] and indicated..."

* {{green|who had headed the Mariner and Voyager projects}}: I'm not clear on the logic as to when names like ''Mariner'' and ''Voyager'' are italicised, but it seems to be inconsistent in this paragraph.

* {{green|Longer travel times meant that components would age}}: well, yes, but I suppose the problem was that they would wear out with age? Things simply becoming older isn't ''necessarily'' a problem.
*: Added "and possibly fail" [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 18:48, 3 April 2024 (UTC)
* {{green|the onboard power supply and propellant would be depleted}}: is this quite true? For the first part, perhaps, but wasn't the point of the gravity assists that the overall mission would require less delta-v (and so less propellant) than a mission that didn't use them?
*: The onboard propellant is only used for inflight maneuvers, so gravity assist maneuvers would require more of them. [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 18:48, 3 April 2024 (UTC)
* {{Green| Some of the gravity assist options also meant flying closer to the Sun, which would induce thermal stresses. However, the IUS was constructed in a modular fashion, with two stages}}: I'm not sure I see the point of the ''however'' here -- what's being contrasted? It sounds like we've just discussed reasons why the IUS was a ''bad'' component for this mission, and are now about to discuss reasons why it was a ''good'' one: could that be made clearer and more explicit?
*: Reworded the paragraph, and got rid of the "however". [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 18:48, 3 April 2024 (UTC)
* {{green|An important decision made at this time by Ames and the JPL was}}: a bit mealy-mouthed: better as ''Ames and the JPL decided...''? Always better to show, not tell, that it was important, and we don't (in this paragraph at least) really set out ''why'' this made a difference.
*: The paragraph ''does'' explain: ''This allowed it to take high resolution images, but the functionality came at the cost of increased weight.''

* {{green|The IUS was not powerful enough to launch a payload to Jupiter without resorting to using a series of gravity assist maneuvers around planets to garner additional speed}}: could we rework the double negative: something like "to launch a payload to Jupiter, the IUS needed to use a series of..."? I would also stick a full stop after ''additional speed'' and then do something like "Most engineers regarded the use of such maneuvers as..."

* {{green|Casani solicited suggestions for a more inspirational name for the project, and the most votes went to "Galileo" after Galileo Galilei}}: in both cases, I find myself asking: [suggestions/votes] from whom?
*: Added a bit about this. [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 03:18, 4 April 2024 (UTC)

* {{green|Lifting Galileo and the IUS would require}}: in this and similar sentences, if they actually ''did'' the thing suggested, it's better in the indicative: ''Lifting G. and the IUS required...''.
*: As explained further on, they did not do it. [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 04:12, 4 April 2024 (UTC)
* {{green|By late 1980, the price tag for the IUS had risen to $506 million (equivalent to $1.714 billion in 2023). The USAF could absorb this cost overrun}}: I'm not totally clear on the relationship between NASA and the USAF in this project. Had NASA contracted the Air Force?
*: As explained earlier, the USAF was in change of the two-stage IUS, NASA of the three-stage one.
* {{green|What saved it from cancellation was the intervention of the USAF}}: less verbose as ''the USAF intervened to save it from cancellation''.
*: I fail to see the value, but changed as suggested. [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 04:12, 4 April 2024 (UTC)
{{collapse bottom}}

* {{green|in reality, the antenna got stuck while in space and didn't open all the way}}: I know that brevity is important in a caption, but I don't think "got stuck" or a contraction are the right [[WP:TONE]]. Suggest "the antenna's motors stalled, preventing it from fully opening", or similar. ''[[User:UndercoverClassicist|<b style="color:#7F007F">UndercoverClassicist</b>]]'' <sup>[[User talk:UndercoverClassicist|T]]·[[Special:Contributions/UndercoverClassicist|C]]</sup> 10:27, 3 April 2024 (UTC)

*: Not sure about the revised {{green|but in reality the antenna could not open all the way}}: to me, that reads as if it was impossible for the antenna to open fully.

*::: I still think we have the same problem: it sounds as though the antenna wasn't extendable at all. How about "failed to extend", which makes clear that it ''should'' have done so?

Another few:

* {{green|pressurized atmospheric entry probe to a vented one}}: it would be useful to know what these things are: perhaps clearer if we explain it by what the probe would or wouldn't do?
*:
* {{green|But the three-stage IUS was itself overweight}}: It's not a ''rule'', as such, but most style guides would avoid starting a sentence with ''but''. More importantly, if we ''do'' use ''but'' here, we're setting up some followup in which this additional weight prevented something from taking place, and that never comes, so the paragraph would read better with something like "Furthermore", "Additionally", or indeed nothing at all.
*: Changed as suggested. [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 03:18, 4 April 2024 (UTC)

* {{Green|109 percent of their rated power level}}: can we explain or link what a rated power level is?
*: I will see if I can dig up a source. [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 07:01, 16 April 2024 (UTC)
* {{green|The second was that despite this, it was also more gentle than the IUS, as it had lower thrust, thereby minimizing the chance of damage to the payload.}}: grammatically, needs a comma before ''despite this'', but then becomes quite a winding sentence. I would go with something like {{green|The second was that it had lower thrust, thereby minimizing the resultant forces on and therefore the chance of damage to the payload.}}
*: Split sentence. [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 07:01, 16 April 2024 (UTC)
* {{green| David Stockman, the Director of the OMB}}: per the ever-confusing [[MOS:PEOPLETITLES]], we should decap ''director'' here.
*: De-capped. [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 07:01, 16 April 2024 (UTC)
* {{green|could damage the spacecraft's optics and possibly the spacecraft itself.}}: the optics are part of the spacecraft, aren't they? Suggest "and possibly other parts of the spacecraft", or even something like "other, more mission-critical parts of the spacecraft", "other parts of the spacecraft, particularly..."
*: Re-worded. [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 07:01, 16 April 2024 (UTC)
* {{green|reads from one memory location disturbed those in adjacent locations}}: not quite grammatical (what's the antecedent of ''those'': grammatically, it should be ''reads'', but you can't damage a read). The noun "reads" is also a little tricky to parse. Suggest "repeatedly reading data from a single data cell damaged the other data cells around it", or similar.
*: Re-worded. [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 07:01, 16 April 2024 (UTC)
* {{green|Shuttle-Centaur project}}: needs an endash, I think, as this is really "Shuttle plus Centaur" (compare Lee{{ndash}}Enfield or Mason–Dixon line) ([[MOS:DASH]])
*: [[MOS:ENBETWEEN]]: ''Generally, use a hyphen in compounded proper names of single entities.'' [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 07:01, 16 April 2024 (UTC)
*:That's not the case here, though, as there's nothing called a "Shuttle-Centaur" (that is, a Centaur that is also a shuttle, as distinct from maybe a "Saucer-Centaur"). This is instead the example given of {{green|Wilkes-Barre, a single city named after two people, ''but Minneapolis–Saint Paul, an area encompassing two cities''}} ''[[User:UndercoverClassicist|<b style="color:#7F007F">UndercoverClassicist</b>]]'' <sup>[[User talk:UndercoverClassicist|T]]·[[Special:Contributions/UndercoverClassicist|C]]</sup> 08:38, 16 April 2024 (UTC)

* {{tq|and the Space Shuttle main engines (SSME) running at full power—109 percent of their rated power level.[20] Running at this power level necessitated the development of a more elaborate engine cooling system.[28]}} - two questions. First: full power should be 100%, so is it correct to say "at full power" here? Maybe smth like "above its full power"? I don't know the right terminology here, so maybe I'm wrong. And second: why more elaborate cooling system was needed? The engines were not designed to work at full power?

*"Galileo performed close observations of another asteroid, 243 Ida, at 16:52:04 UTC on August 28, 1993, at a range of 2,410 km (1,500 mi). Measurements were taken from Galileo" Was 2,410 the closest approach or the point where they started taking observations? Maybe I'm wrong but my understanding of these flybys is that there is a brief period of time to take observations, and observations start and end at a greater distance than the instance of closest approach.
*: I have elaborated on this. It was both the closest approach and the point where they started taking observations, due to an operational problem.

*"It orbits faster though, with a rotation period of 1.769 days. As a result, rotational and tidal forces are 220 times as great as those on Earth's moon." I thought that the greater mass and maybe proximity of Jupiter to Io as opposed to the Moon to Earth would explain the tidal forces.

*"a signal from Earth takes anything from 35 to 52 minutes to reach Jupiter". A few points here. First, "anything" is kind of informal language. But more importantly, I'd explain the nature of this variation; i.e. it's because the Earth-Jupiter distance varies depending on where they both are in their orbits; readers who are not familiar with how this stuff works might guess it has to do with other factors like varying amounts of power available on the spacecraft, or whatnot. Also, I think these sorts of things are typically cited as round-trip time because that's what really matters if you're trying to do remote control; downlink delay to send telemetry, plus the uplink delay to send a command based on the telemetry you received.

* Even more generically, please read through the entire article looking for technical words and consider whether a naive reader would understand them.

* Still talking generically, it might be a good idea to give real-life examples of units that a reader might be unfamiliar with.

*: On average, a 12-Volt car battery can maintain about 5 Amperes for ten hours. That makes such a battery a 50 Ampere-Hour battery. That is equal to around 12 x 50 = 600 Watt-Hours.

* "generated 570 Watts at launch ... rated at 730 Watt-hours." I'm not sure how to handle this better, but it's jarring to have two consecutive sentences talking about power sources using different units (power vs energy). I understand the difference, but I suspect a less technically savvy reader will just be confused and/or come away with the wrong impression that the battery is "bigger" than the RTG, when in fact those values can't be compared in any useful way. I see that you're just giving the data as it's presented in the NASA report, but it would still be nice if there was a better way to present this. Actually, a quick calculation says average of 520 watts x 8 year = 36 MW-Hrs. Upon reflection, this makes sense; the battery only runs the atmopheric probe for the short time it takes to descend and burn up. Hopefully you can find some RS that goes into this sort of analysis so you can present it in the article.

* "This was only partly due to the NASA management's increased aversion to risk in the wake of the Challenger disaster; NASA management also considered ..." This appears to be based on a p 217 quote from Marty Winkler of General Dynamics commenting on his interpretation of NASA management's decision. So I think this deserves attribution as Winkler's opinion.

*"for a time it looked like its next trip would be to the Smithsonian Institution." That's a cute way to phrase it, but maybe it should be stated a bit more formally. Also, it's an unattributed quote from the source, so that's a problem.

=====Nuclear concerns=====
* "plutonium in the Galileo's radioisotope thermoelectric generators (RTGs) and General Purpose Heat Source (GPHS) modules" This makes it sound like these are two different things, each with their own plutonium supply. My reading of [[GPHS-RTG]] leads me to believe this is a single unit with a single plutonium supply which performs both functions, so this needs to be clarified.
*: Correct. Changed to "''Galileo''{{'s}} GPHS-RTG modules [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 21:36, 13 April 2024 (UTC)
* The overall tone of the first paragraph seems in violation of [[WP:NPOV]]. You minimize the risk ("what they perceived as an unacceptable risk") and then state in wiki-voice that "They had been used for years in planetary exploration without mishap", implying that there is indeed no risk.
*: There is a whole paragraph about the risk. The issue is what degree of risk is "unacceptable". [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 21:36, 13 April 2024 (UTC)

* "an accident might have released up to 11,568 curies (428,000 GBq)." Another example of a unit which is almost certainly unfamiliar to most of our readers. Is that a lot? Are we talking a couple of dental X-ray's worth or another Chernobyl? Likewise with "NASA concluded that the chance of such a disaster was 1 in 2,500". I have no idea if that's a lot compared to all the other risks. NASA must have some standard risk analysis budget. How does this compare with other missions? Also, what does "such a disaster" refer to? In ther previous paragraph you give two different scenarios; which of those is this?
*: Chernobyl released between 50 and 185 ''million'' curies; three mile island released about 2.5 million curies. I have no figures on the risk assessments of other missions. Part of my job involves carrying out risk assessments, and the low odds and moderate consequences would mean approval. Linked the unite. Deleted "such".

=====Launch=====
*"There were fears that the spacecraft might be hijacked by anti-nuclear activists or terrorists". I'm guessing this is due to the plutonium, but please don't make the reader guess. As an aside, I also have to wonder about the risk was of sleep-deprived truck drivers in a high speed convoy over an unfamiliar route at night having a crash. :-)
*: Apparently, there is a [[Nova (American TV program)]] episode about this, but I haven't seen it. Added that the plutonium was the concern. [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 21:36, 13 April 2024 (UTC)

=====Venus encounter=====
* "three hours into the flyby, the tracking station at Goldstone had to be shut down due to high winds" If it was being tracked by Canberra and Madrid, why did it matter what was going on at Goldstone? I'm guessing the answer is that by the time three hours had passed, Goldstone had become the active station, but that should be explained for the benefit of our less technically savvy readers. It also seems odd that you give the time of the flyby down to the second ("05:58:48 UTC") implying it's a discrete moment in time, then later talk about being three hours into it. Maybe just note that 05:58:48 was the time of closest approach?
*:Clarified. Note that 10 February in Canberra and Madrid was only 9 February at JPL. [[User:Hawkeye7|<span style="color:#800082">Hawkeye7</span>]] [[User_talk:Hawkeye7|<span style="font-size:80%">(discuss)</span>]] 21:36, 13 April 2024 (UTC)

* You might also want to explain that doppler provides a direct measurement of the relative velocity between two bodies (in this case, Galileo and the Earth). Again, this is something our more sophisticated readers will know, but will leave others struggling to understand.

*:Yeah, but I think it would still be better to provide some explanation here. I suspect most people are familiar with the "train whistle gets lower in pitch as the train passes" demonstration, but I don't think they would necessarily make the leap to "by measuring the change in carrier frequency of the spacecraft's transmission compared to the nominal frequency, you can compute the spacecraft's velocity relative to Earth", and [[Doppler effect]] isn't much help for the casual reader trying to figure that out. Likewise, they might have heard of "Doppler radar" in the context of some gizmo the cops use to give you a speeding ticket, but I think it's asking a lot to expect the casual reader to understand the application of that to space navigation.
