Unless the weather turns bad and the wind picks up.

Depends on the composition of the atmosphere. Lower gravity implies a more rarified atmosphere, so 'air'ships would require a larger volume of lighter-than-'air' gas.

Methane, ethane... plentiful on hydrocarbon rich bodies such as Titan.

Kinda like giant ghosts in a snow storm.
I do like the shape of these ships,
Great work

Did you get your inspiration from this? vimeo.com/108650530

partially yes, its a great movie, but the idea of "lighter-than-air" planetary probes is quite old.

same here... but i really doubt, because space exploration doesn't seems to be the priority. Look at the recently launched Orion - it is just Apollo on steroids. Actually it is a step back, especially when you consider ambitious single-stage-to-orbit programs like Venture Star. That would be a decent space shuttle replacement... not the Orion.

Unlike unmanned probes, manned space exploration will remain a costly affair, never routine. I disagree with your thoughts on Orion; I think it is the way to go. Simple works best in space. Complex spacecraft like the space shuttle turned out to be a very costly dead end (no pun intended). I worked on the X33/Venture Star (and lost my NASA science writing job when Congress pulled the plug on the effort in 2000). I knew it was a dead end, good for LEO use only. We just don't need fancy, complex winged spacecraft to shuttle back and forth to space stations. SSTO is a wonderful concept but it seems daunting, so why wait? Let's fly! A Ford Focus gets you to the exact same destination as a Lexus, and in the same time. The Lexus is for your ego and to show off to others that you've made it. Meanwhile, the Focus does the same job without the hype. I think we've been over stimulated in our expectations by science fantasy movies and TV shows and novels--a lot of it is wishful daydreaming, kids stuff. Any step into space is a step forward; it will always remain dangerous and demanding. Orion works because it follows the physics of interplanetary flight. You can't reinvent the wheel if it already works (i.e., Apollo). It worked and will work again. Consider Soyuz's long history and success as space's Ford Focus. Consider all the national infrastructure we trashed based on poor national space policy following Apollo. Honestly, it's the tribal politics of space I worry about more than our collective national ability to accomplish the mission.

Agreed.
I would think that high altitude airplane+shuttle a la Virgin Galactic is a nice try, as the biggest problem is the lower part of the atmosphere and initial velocity/momentum.
Looking at three stages rockets for the Moon is just not that anymore. There are plenty of otherwise valid options, like LEO assembly of a larger spacecraft.
Kinda sad it all started that well in the 60-70s then bailed out completely. We would have been living in a much different World by now...

But if the atmosphere is less dense will it work!? ^_^;
👍: 0 ⏩: 2
maybe the atmosphere is not less dense? anyway - airships and balloons can be used in almost any atmosphere, especially in combination with low gravity. For example Jupiters moon Titan has 5 times denser atmosphere that earth and low gravity - a relatively small balloon can carry a lot of cargo. Titans atmosphere is so dense that it is hard to look at the surface of the moon - probe with balloon can be a great tool to scan or photograph the surface.

Wikipedia: "The atmosphere is so thick (on Titan) and the gravity so low that humans could fly through it by flapping "wings" attached to their arms." There you have it! Seems like there are a lot of factors! Temperature and celestial neighbors too! You win the contract to build the balloon aircraft. ^_^

That's what I thought too! Hot "air" perhaps. Helium too rare, hydrogen too explosive.
👍: 0 ⏩: 2
Weeeeell you might be able to use hydrogen on any place without oxygen. ^_^
👍: 0 ⏩: 1
i think helium is a better option. Because you don't need fuel to heat the air... just inflate the balloon or airship and you can fly for ages...
👍: 0 ⏩: 1
helium is rare on earth, but in the space - it is the second most abundant element. Can be "mined" and of course can be transported from Earth.

yeah, balloons were actually used on Venus back in 1980s... and can be used on Mars or Titan moon for example...

I think we should do it. Titan sounds like a worthy start, although further, we may get more exciting information from there than Mars. In my opinion at least.
