Galileo (spacecraft) was a good article nominee, but did not meet the good article criteria at the time. There are suggestions below for improving the article. Once these are addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake. Reviewed version: February 14, 2008 |

[edit] Name
Is there anyone who can explain why GalileO and not GalileI is the name? I would say that the surname is Galilei, so it is named for his first name? Why?
- Because that is the name that the astronomer is commonly known by. AKRadeckiSpeaketh 20:05, 22 November 2007 (UTC)
[edit] Atmospheric Entry probe
hi There is a nice picture of the atmospheric entry probe in "atmospheric reentry" page on wikipedia. Maybe nice to add?
The instruments aboard Galileo should be described in more detail. Information is available at: http://www.jpl.nasa.gov/galileo/instruments/index.html
- Done! :) --Deglr6328 06:08, 23 Jul 2004 (UTC)
According to "Journey Beyond Selene" by Jeffrey Kluger (1999), the low-gain bandwidth was initially 8 bits per second. A recent Slashdot 'legacy' article claimed that the bandwidth was raised to 120bps using compression methods. Also, Kluger stated that the high-gain deployment wasn't attempted until Galileo had passed Mars ... was that after the *first* flyby?
- I'm the author of that slashdot article :-D ; fixed a couple LGA related things and added more detail on the increase to 160bps.--Deglr6328 05:52, 18 Jul 2004 (UTC)
- This passage - "The probe would have been melted and vaporized after many hours of falling, completely dissolving into Jupiter's interior. The parachute would have melted or been burnt first, after roughly 3-4 hours. Then the probe would have gone into a free fall through a black dark abyss lasting many hours. Due to the higher pressure, the metals would have been vaporised once their critical temperature had been reached."
- (1) It repeats "melted and vaporized" twice, with "parachute failure" sentence _in between_, but parachute failure happened _before_ "melt and vaporize", right? It just doesn't sounds nice.
- (2) "black dark abyss" sounds like poetry (I mean, it is possible that it is factually incorrect). In reality, at tamperatures where metals melt, atmosphere wouldn't be "black" anymore. It will shine with red from temperatere, probably. —The preceding unsigned comment was added by 195.212.29.171 (talk) 08:27, 29 December 2006 (UTC).
[edit] incorrect energy units?
The article says "The PLS will measure particles in the energy range from 9 volts to 52 kilovolts." Energy is in joules, not volts. I presume that the author is referring to the 'electronvolt'. What do you think? Bobblewik (talk) 17:36, 17 Sep 2004 (UTC)
- Yes, I saw that when I added it to the article but figured it might actually be "volts" because I confused it with the plasma WAVE subsystem and thought...well maybe its measuring the electric field strength etc. However reading the homepage http://www2.jpl.nasa.gov/galileo/instruments/pls.html clearly indicates (~2/3ds down) that it is measuring particles with eV energies. However the same page says it measures from "9 to 52 kilovolts" and "0.9 eV to 52 KeV"....I'm going to go with the latter.--Deglr6328 01:56, 18 Sep 2004 (UTC)
[edit] Impact of mission
Is it worth a section on the impact of Galileo on later deep space missions by NASA? The planning of the project began in the mid-1970s but the design was frozen before the Voyager results could be fully interpreted. As a result the Jupiter atmosphere probe had less scientific interest than a probe of Europa. Arguably a consequence of Galileo was the 'faster, quicker, cheaper' NASA ethos of the 1990s.
- that seems a bit speculative at best....--Deglr6328 05:29, 29 August 2005 (UTC)
[edit] Galileo's Atmospheric Entry Probe
"All the probe's electronics were powered by lithium sulfur dioxide (LiSO2) batteries which provided a nominal power output of about 580 watts with an estimated capacity of about 21 ampere-hours on arrival at Jupiter."
This is missing important information - knowing what the total power output and the amp-hour capacity was is totally useless without knowing what voltage the battery was providing.
[edit] What this article needs
Pictures of Jupiter! That was the major mission of Galileo... (just my opinion)
Whoa! Way too much information! Try to speak of the details in a little less complicated manner.
[edit] Did Galileo nuke Jupiter?
I found a bizarre story on the internet about how the Radioisotope Thermoelectric Generators (RTGs) revealed their innards of Plutonium 238 pellets as the spacecraft disintegrated as it entered Jupiter’s atmosphere. The article describes the existence of a “black spot” on the surface of Jupiter which had never been observed before. This black spot appeared roughly one month after the craft slammed into the planet. It was at this time that the Plutonium would reach the point in Jupiter’s atmosphere in which the pressure could crush the pellets to supercritical mass causing a nuclear explosion. The black spot is supposedly the carbon released from the dissociation of millions of tons of methane molecules in the surrounding atmosphere. Maybe this should be mentioned in the article? Here’s the story: [1]
- That is a speculation site and it's contents shouldn't be on a Encyclopedia. None of the "facts" are verified.--Ricnun 20:54, 6 August 2006 (UTC)
- Wacky conspiracy theories do not belong here. --Deglr6328 04:38, 7 August 2006 (UTC)
[edit] atmospheric entry probe
There is a nice picture of the atmospheric entry probe on the "atmospheric reentry" page on Wikipedia. Maybe nice to add?
[edit] Music / Greetings
I was watching a documentary last night and I think it said that Galileo has Mozart's The Magic Flute, a song by Chuck Berry, and greetings in 60 languages on board. Is this true or did I mishear it? If so, does anyone know what the Chuck Berry song is. Lastly, is it worth including in the article? Dgen 23:22, 11 February 2007 (UTC)
[edit] Eight Years
This spacecraft spent 8 years in orbit of Jupiter and took no pictures of the planet ? What a waste. 65.92.244.134 11:02, 5 April 2007 (UTC)
[edit] Theme song?
Back when the probe dropped into the atmosphere, a group of engineers at JPL adapted the lyrics of Tom Petty's song Free Fallin' as a sort of theme song. They used to be posted to the web, but I can't find them now. Anyone remember the site, or the lyrics? If they can be ref'ed, I'd like to add this bit to the song's article.

[edit] Sorry, but this is no way a GA!!
First, there are two full sections until you encounter the first reference. THis is inadmissible. Secondly, please reformat titles such as the table of contents won't take this much space. Thirdly it has a tag placed for expanding a section. Lastly, pelase add al least the titles to each of the references. Nergaal (talk) 10:35, 14 February 2008 (UTC)
