What eight plants are impossible to explore? Is it possible to venture on Neptune's surface or atmosphere?
If we're talking about human exploration:
Mercury - Too hot
Venus - Could survive in upper atmosphere maybe (that whole blimp idea)
Earth - Duh
Mars - This could also work
Jupiter - Possible to survive in the same conditions as Venus, but much more difficult due to the extreme cold
Saturn - Again, floating on the surface of a gas giant is possible, but I don't know if it would be feasible anytime soon
Uranus - Probably too cold, we'd need some amazing life support
Neptune - Even colder, trip would take a lifetime
Pluto - Not a planet, but basically the same as above.
>Pluto - Not a planet
oh....you're one of those people.
first of all, Uranus is actually colder than neptune. And Venus is actually hotter than Mercury. It's not just distance to the sun that matters (especially in the Jovian planets). Secondly, even the calmest of the gas giants have upper atmosphere wind speeds of over 450 mph, I highly doubt any human would ever be able to just "float on the surface". Life is nothing like the magic school bus you basement dwelling fuckwit.
Mercury has a really slow rotation period so the other side is freeing. So it's also a candidate for exploration. but it would be pretty insane. Both sides are on some really intense temperatures.
>Mercury - Too hot
Nah, with no atmosphere to worry about, staying cool isn't that big of a challenge. Just stay in the shade and it's otherwise pretty much like living on the Moon. Much easier than trying to hang out in limbo above Venus.
The big issue with Mercury is getting there. It's not a convenient place to stop or even fly by.
Yeah, but it's a much more challenging proposition than subsisting in a planet with little to no atmosphere to cause problems.
Atmosphere is thick enough for aerobraking, yet thin enough not to cause major thermal management problems. Easily the easiest place to reach and explore other than the Moon and perhaps Phobos.
>Jupiter; Saturn - Possible to survive in the same conditions as Venus, but much more difficult due to the extreme cold
Won't work. Balloons wouldn't float in the atmosphere (unless heated and very, very large) of these two since it's composed of hydrogen and helium. But these planets DO have the most interesting Moons, which could be far more amenable to exploration and settlement.
Same problem as Jupiter and Saturn, only the lower temperatures might make it feasible to survive in a hot gas balloon at elevated pressures. Still tremendously more difficult than any of the terrestrial planets.
>Pluto - Not a planet, but basically the same as above.
With no atmosphere, it's again much like trying to live on the Moon or in space. Or more closely, on one of the Jovian moons. VERY difficult to get to, though.
It's radioactive as shit, too.
This may make exploring it's moons a challenge.
>Both sides are on some really intense temperatures.
It doesn't have an atmosphere, so it's a vacuum on its dark side. Vacuum is a perfect insulator.
Staying warm in a vacuum is not a challenge. Cooling off, is.
Now you've got me wondering just how many celestial bodies including the moons in our soloar system we could actually explore. There must be atleast several dozen including all the moons. A base on every body in the solar system, what an achievement for mankind that would be.
What an achievement! To be able to establish bases all over the moons and set a commune there! Wow that sounds perfect. Imagine people living in Europa, or Ganemedes or any other moon of Jupiter for example, and come around for a 'vacation break' to Earth.
>implying pluto isnt a planet because its small
A dwarf planet is still a planet.
The size of the object isn't relevant to its classification as a planet as long as it has hydrostatic equilibrium.
