Talk:Exploration of Jupiter

I'm confused...
...by this:


 * "Reaching Jupiter from Earth requires a delta-v of 9.2 km/s,[1] which is comparable to the 9.7 km/s delta-v needed to reach low Earth orbit.[2] Fortunately, gravity assists through planetary flybys..."

The reference http://www2.jpl.nasa.gov/galileo/faqnav.html says "Starting out from a low Earth orbit, a spacecraft needs to increase its speed by 9 kilometers per second (19,440 mph) in order to reach Jupiter" (my italics). Also, as it stands, the word "fortunately" doesn't make sense. It implies that acheiving the stated delta-v for Jupiter is difficult, and yet if it's the same as required for LEO then it can't be that difficult as that operation is very routine. Possibly the difficulty is because the 9.2 km/s is on top of the delta-v needed for LEO, as the reference seems to be saying. Maybe someone who understands this could clarify the text in the article in these respects. Matt 11:07, 6 June 2007 (UTC).

Launching a spacecraft on a direct Jupiter trajectory does requires a great deal of energy. In 2 cases Galileo and Cassini, the on pad mass of the spacecraft were too great to fly a direct trajectory to Jupiter. In other words, no launch system at the time could provide enough delta-V to make a direct flight. If it wasn't for the possibility of gravity assists maneuvers these spacecraft would never have reached Jupiter. So the word Fortunately makes sense in the sense we can still reach Jupiter with a high mass probe using gravity assists.

Merge with Colonization of Jupiter
As long as we're discussing manned exploration, how about moving material from that article to this one? That article has never been sourced and I would prefer a small number of sourced sentences to a large, unsourced paragraph that basically amounted to wishful thinking.

 * Exploration and colonization of Jupiter ? Ruslik_ Zero 12:21, 25 June 2009 (UTC)
 * Merge into the newly created section on manned exploration: i.e. Manned exploration and colonization (and leave the title in its present state since the colonization part is minor). Nergaal (talk) 16:20, 26 June 2009 (UTC)
 * OK; I've merged it. But it's going to have to either be sourced or radically trimmed.  Serendi pod ous  16:37, 26 June 2009 (UTC)

Is the comet actually part of this article?
Every time I open the article I get question marks about how the comet fits into the scope of the article. One solution is to throw it out completely and put a sentence or two in the Galileo section, while the other one would be to expand that section into an Earth-based observation and exploration one. And speaking of this: is Hubble-looking-at-Jupiter within the scope of this article? Nergaal (talk) 04:52, 10 July 2009 (UTC)
 * Perhaps not. But please let's wait until the reassessment is over before making any more changes.  Serendi pod ous  09:03, 10 July 2009 (UTC)
 * Expanding the remit to telescopes would perhaps go beyond the concept of "exploration", so I think the best option is to merge the appropriate info with the Galileo section and ditch the rest.  Serendi pod ous  21:24, 10 July 2009 (UTC)

Now that this is done
Is it actually FAC-able? To what I recall, the only section that may need more careful expansion/checking/cleanup is the paragraph of Major scientific results of the Galileo mission include:. Nergaal (talk) 00:20, 11 July 2009 (UTC)

query: is this actually true? Can't Mars be used as a slingshot too?
