Talk:Exploration of Neptune

message: As far as I know, Neptune is an ice giant, not a gas giant. It has extensive atmosphere, and below it, it's covered with an ocean of water and ammonia in both liquid, and icy state. What about sending a boat that could land on the planet? Were there any plans like that? Critto (talk) 14:12, 22 November 2011 (UTC)
replies: text: Sure, if your boat can withstand pressures in the gigapascal range! That's a rather difficult problem to get around. Double sharp (talk) 17:17, 19 July 2015 (UTC)

text: Good point about the ice giant vs. gas giant. But afaik even the so-called gas giants have layers of solid (crystal) matter. Inside Jupiter it is just hydrogen for the most part, but at the extreme pressures it is compressed to a solid metal. Whatever the truth is, it would be technically (physically?) impossible to reach these layers with a functioning probe. One could however have stationary probes floating and circling about in the planets dense atmospheres. The pressures here are manageable, it would be like floating on an ocean, except there will be no well-defined surface. And the extreme wind systems will carry the probe round and round the planet in a rather stable trajectory. RhinoMind (talk) 01:43, 3 August 2015 (UTC)
replies: text: The nomenclature has changed. Years ago, they were considered gas giants, but as it was realized how different Uranus and Neptune are from Jupiter and Saturn, the name was shifted to "ice giant" planets. Skepticalgiraffe (talk) 20:16, 11 June 2020 (UTC)

message: Hello. 
User:Cmglee formerly added a "missions to the outer Solar System"-template here back in July. I Subsequently removed it from the page, mainly because of some errors in the template info. However, I support the idea of a template such as this (if it contains correct information) and would like to discuss it here. The template that I removed is shown to the right.

One of the errors is the mixing of actual missions and decommissioned and abandoned missions, such as the Ulysses. Maybe someone is able and willing to update and correct the templates info?
