I think what we want to do is assemble stuff in orbit. I don't mean like the ISS. I mean like setting up a robotic base on some icy-stony rock somewhere, and actually building probes and making fuel from the materials on the asteroid. Avoiding launch costs, avoiding all the delta-v needed to get something from the ground to interplanetary space.

To pollute less, cars just use grams of platinum combined with rhobidium and paradium (which are more cheap) in different cycles to save platinum.
Paradium, you say?

Back on topic...
I don't think an economy in space is really going to start up until we can get stuff from space, make stuff in space, and live in space. Basically, once space is independent of Earth, a space economy will start taking off. Otherwise, we're just relying on the planet for our needs. That isn't going to work in the long run. Once we actually have an independent space economy, I worry it will remain a space economy for a long time. It'll be more profitable to have and sell resources in space to people who need them in space (i.e. water ice for rocket fuel, breathing air, water to drink, water to farm in, hydrogen for fusion reactors, yada yada yada) than it will be to bring stuff down to Earth (carry a hundred tons of quite dense metallic material inside a reentry module) and from Earth to space (rocket launches for going up with really big expensive rockets).

Wouldn't an air-breathing engine need to convert Co2 to O2 before burning?
I meant, we need a CO2-breathing engine. One that doesn't need oxygen to work.

The top inch or so is basically all rocks, then below that it is rocks and mud. By the way, in like one minute I will be on a plane and unable to answer posts (uses Internet) so I will see you all and be able to post again in like three hours.

Maybe a SABRE engine that works as a Nuclear air-breathing engine, as long as there's enough air, it produces thrust.
I read the article. It looks like the same tech as in hot air balloons, put into a jet engine. Does it basically heat the air and put it through a ramjet? I doubt it is as efficient as a co2-breathing engine.

It's not geologically active. There is some sulphur in the air and ground but it is from human activities.

Like a scaled-up Skylon.
Kind of. Skylon uses a SABRE. SABRE needs O2. Venus has no O2, but it has CO2. We have to find a way to make it work with that.

There is a "field" of rocks near my house in which I frequently find pyrite (fool's gold). I go there a couple times a week. There is usually a rock with pyrite in it that I can bring home. I don't understand how it seems to replenish itself while I am gone. I can go to a place and there will be no pyrite, then I can go back a month later and there will be some. Is it actually forming on the rocks in timescales we can see or am I just missing them the first times? I have been exploring that place since like 2007 or 2010 or something, and it isn't a very big place, so I don't know how likely it is.
-
We could lower costs for Venus a lot if we had air-breathing engines that work there.

Does "to Eve" strictly mean being on the ground?

I don't think any of them are terraformable.

Where's the launch video?
-
Does the KSC Switcher work in RSS? If so, does it have launch sites on all the continents?
-
I can see Ross Island. And Cape Adare. And Dumont D'Urville. And Casey and Mirny and Concordia and Vostok. Actually, that's like half the continent. RSS is more accurate than I thought, wow.

Why not launch the rover vertically? You only need it horizontal when it's landing. What I do is I just put parachutes on the rover and detach it from the transfer stage during reentry, so that it reaches the ground fine. If it is without an atmosphere, it generally has low gravity and I can just land the transfer stage and detach the rover after. Exceptions to this are Tylo (no atmosphere, high gravity), Jool (no ground), and Kerbol (no chance). Those exceptions are okay because I've never built a Tylo Rover, a Jool Rover, or a Sun Rover before.
On second thought, I wonder if a sun rover is possible.

We're getting JWST in a couple years.

Actually, Europa or Enceledus life would be good enough due to the lack of dust sharing between Earth and Jupiter.
Billions of years ago, when life first appeared, there was a lot more dust in total. We know things were crashing into each other back then, the evidence is all over the place. It's conceivable that water-based life inside Europa or Enceladus could have got there from Earth. My point was more that Titan's life would be so different from Earth's life that it is impossible for them to share a common origin, and that the only way you can pretty much guarantee the independent origin of life somewhere else would be in another star system. By natural processes, those are pretty much unreachable.

I vote BCE. Billions BCE. Before Earth had any atmosphere or substantial mass. When it was the size of Deimos. I'd pick up a rock and throw it into orbit.

EDIT: nvmnvmnvm

Define rocket.
-
Oh, okay
I assume it's still being recorded, though, so those of us who can't view it can see the launch later.
EDIT: Got it, can see satellite.

There is only graphs in the stream

Quickly how do I see this
