"Wait, so the whole CubeSat is pressurized?" The phone is in space. But it's shielded by the bottle and the inflatable module. A coke bottle can reist up to 1200 pascal according the internet. So. That' not the problem. we can do it up to 5 bars without problem. with an Effectrive volume of 0.2 litre we can do it.

That sound awesome. Like really. If we can do that, we should.

Don't want to take the job of the ESA fan, but they got an university behind them. If we can build a void resistant small container, it would be easy, even in an 1U. We just need a small, inside camera, a smartphone and an antenna (I don't count the kerbal toothpick flag on it but). Some Iphone can do the job. OOOOOO OATTBBO OATSBBO OOOOOO A being the antenna, T the bottle, S the phone and B the inflatable part. Don't point the smartphone to space, protect him, one side with the bottle, the other one by the inflatable, the camera on it looking inside the inflatable (who might have a window for space photo). Advantages : 1) we don't need spacegrade processor. 2) we don't need space grade camera 3)possible in an 1U

Are u millionair, or something ? An 1U sat, we can launch, maybe even freely via esa or nasa

That would take at least 75% of the module for a 10 litre and 50% for 5 litre. Kinda throwin' number out of my hat, but I think they are accurate from my experience in dive bottle(really usefull on a space launch). The problem, is how we will build a bottle sized for the 1U, or 2U and 3U. And don't expect anything more than an 1U sat. Does someone know if plastic bottle, with 5 bars can survive in space ? Cuz that's easy to model with a 3D printer.

http://www.snowbigdeal.com/avalanche-airbag-reviews-weights 7 LBS (3.5 Kg) for an 170 Litre airbag avalanche designed. 2.5 kg for airbags on a car. (On a french site they said that it's around 700 gr for the bottle of 170 litre, so 100/150 g for the bottle and 50 gramme for a good valve should do the job. With that, we need to include 200/300 g for the inflatable module and it's contained plants, sprouts,...) Count 500 g, no less( the size isn't quite the problem here, we can go to 20 bars without problems (50 bar for oxygène kit for dive, on an 35cm long cylinder). with the folded equipement, forget about thrust or anything, but enjoy our inflatable module.

That's what's good with the inflatable modules. They does inflate. Airbag might be an interesting thing to look at. Lemme check

"Yea, they actually had something that can explode. That's a testimony to them having 1 billion times more experience than vast majority of people in this topic has. ;)" Launched a small candy fusee out of a baloon.It didn't explode but kinda ripe off the baloon and one of the fin then goes full derp, but that's what parachute are for. At least it didn't exploded at all.

Don't even have the beginning of a clue. But if u don't contradict me, we can safely assume that it's possible. That could only be a really small one. But we do need either plants or bacteria for to test-prove that he won't get a leak in space (if they die, too bad, inflatable module can't be done with the used technology) and that actually might interest nasa.

I am quite sure that our space program is way better engaged than, for say, congo's one (2 explosion on the launch pad. one explosion in the near farm). And random mean that someone could also be the top executive on the NASA.

That's hard, okay. But using math it's easy, IF both transmitter and receiver can be precise enough.

"But yea - pointing at the target is a major challenge. Both: for receiver and transmitter." We have the orbit informations.We have the satelit orientation. That's not even a problem dude.

Inflatable module. Let's try it. We might even put plants on it (we does need some chemist who can give us a reaction for it)

So, the problem for orienting the craft is solved. Orient at the sun and it's good One problem solved. Just thousand of them left.

1) Don't even think about it. 2) might be feasible. But still useless and not kerbal. 3) So, how do u intend to get someone to put a bomb on their millions of dollars launchs ? 4) Feasible. 5) we can try. 6) Someone can hack the nasa for us ? Probably not. Otherwise, we can inflate a module in space and monitor the way it's affected in space.We can even try a patchwork for the inflatable module, thus doing moar science:cool:

"On a serious note: think about reliable technologies" Kerbal space program. KERBAL. Anyway, CAT is using also an untested IIRC propulsor. Thus, your point is invalid. And failure still mean datas.

For pointing that's quite easy. The camera can record a revolution around the earth, and so, using some maths, we can easily get the rotation of it and thus it's actual pointing.

Didn't knew. Does the thrust got from it is linear to the angle ?

Sails. E-sail for example. Not tested for what I know, and have the avantage that it can only propulse in a single way. The opposite of the sun.

Space is big. Earth is small. Pointing the ship at one direction and go on. If u have enough delta-V u might arrive, uh somwhere. More seriously, we can use the gps system, don't we ? Or using the 1st orbit data and slow inducted, and using the transmissions energy for to correct any change. Then for to point, that's what our video is for

We could maybe use the earth magnetosphere for to propulse ? We charge a small part positevely, and let it go, then negatively around the poles with another,.. What real life don't work like that ? Or build an inflatable module ? (some reactions to make the gaz, then plants/reprocessing transform it into a breathable athmosphère CO2 has a low energy I tough so could be feasible). Or solar sail

Venus sound easier too hit and there is more science to get done (via a baloon). Let's go to venus

For LEO we should try new propulsion system. Like for exemple we launch our cube into LEO it separate in 2 piece, one with a sail the other one who fire something (the same way the solar sail work but in a way more controled way). The sailed probe after a flyby on the moon is lost in the interplanetary. We can maybe get founding for this or even a free ride. http://en.wikipedia.org/wiki/Laser_propulsion If we don't do science we won't get anything free and I doubt about the ability of kickstarter for the amount we are talkin' about. We could also try in situ the E-sail ? Or using some condensater, charge them in orbit and fire the energy back to earth. For uh, Science and maybe a low comsuption light ? We could also, using plants make some rocket fuel. For show once again. Or launch ra drawing of a colomb from orbit to wars (need thermal shield tough) And ONU could give money for that. There is plenty of studies to get done in space. And many university would love that their studies get into space. We could even do docking by using the magnetic field of earth for to slow a craft and speed the other one. (kinda come up with that idea writing it so dunno if feasible or anything.)

That look awesome but for what I know space is a scary place. Radiations, solar flare, high energy electrons,... So how will u protect the craft ? A launch to venus sound way moar feasible since the thermal shield needed could be directed to the sun during the transfer, and thus prevent spending weight in shielding. It would need something like 3k from LEO (2.5 to interplanetary and 0.5 to raise the perige), wich is feasible. ANd we could get found for to study the venus athmophere via a ballon hide behing the thermal shield who would fall back in venus. The interplanetary craft used as a relay and would study the magnetospher of venus + weather. I don't believe that either squad nor musk would spend the price of that sat just for pub. So we need to make science otherwise we won't achieve anything else than LEO PS: Sorry for my pitoyable english. Feel free to insult me for it. PS2: Aye first post on the forum \o/
