I wouldn't call it cheating but I am pretty envious. I got: Man I'm just sitting here staring at those google fiber results and can't wait until its widespread.

When I was 10 I went out and bought my first computing device, it was the original iPad. It ran on Iphone operating system 3.2 and had 256Mb of ram. I still use it even though I have a newer Tab pro because I still have shows on it. I like the quick iOS interface and such but when it comes down to it, I prefer my Tab Pro over my 5s and iPad. For starters, when it comes to raw processing power and storage, Samsung and android devices tend to beat out Apple products rather consistently per price. A few examples of this are Phones like the Galaxy S5 and Oppo Find 7, both have similar price points to mid storage iPhones. The find sports a 13mp rear camera and the s5 has a 16mp one, the iPhone is left with just an 8mp camera. Another point is the pixel density of the screen. Now keep in mind the iPhone was released a few months before the other two but the discrepancy is still too large for that to account for it. Back to pixel density, both phones are larger yet still usable with one hand and both have a higher pixel density. The S5 has a density of 432 ppi on a 5.1 inch screen and the Find 7 has a density of 538 ppi on a 5.5 inch screen. The iPhone 5S is left with a density of just 326 ppi on a tiny 4 inch screen. The next big thing is storage, both the S5 and Find 7 feature 32 GB of built in storage but also accept a Micro SD card of up to 128 GB that is also interchangeable, leaving you with 160 GB of storage. The iPhone is left in the dust once again with a limit of 64 GB that is not expandable. The next point is battery, The S5 features a 2800 mAh batter and the Find 7 has a 3000 mAh battery both much more than the Iphone 5S at a measly 1570 mAh. This brings us to processing power. The S5 has a 2500 MHz 4 core processor and 2 GB of ram. The find 7 also features a 2500 MHz quad core along with 3 GB of ram. Both beat out the iPhone's dual core 1300 MHz processor. The final point here is price. The iPhone comes in at around 800$ for the 32 GB version- On par with the other two phones storage wise. The Galaxy S5 is 700$ and the Find 7 is a relatively low 600$. In the end it seems price is inversely proportional to screen area, density and processing power. Not only are the raw specs better but I find that the Kitkat interface is much better than the iOS 7 one.

Are we seriously considering a Phobos mission? Or is this still hypothetical planning fod funds+?

What year is that noiseless computer from? He says 2 GB is enough for most people when windows 7 needs at least 2 GB and I use 4 just browsing.

We could name it Cubesat Kerman, like the names the kerbals get.

I don't have a picture of the encounter I already landed the probe and got plenty of sciences.

http://ksp.olex.biz/ I used that and had my origin as Kerbin and my destination as Eve. Waited until i got just past kerbin prograde and burned my entire node for 1km/s deltav with no closest approach. I set up another nod that got me an intercept but it took 6km/s deltav so I made another one that I could actually do. It still took more deltav than necessary.

He means orbit capable rockets are also capable of putting a larger payload on a suborbital trajectory to another country.

So a few minutes ago in my career save I decider after Duna I would go to Eve. A logical step considering a transfer window was only a couple weeks away. I had no problem doing a complex double probe deployment on my Duna mission but decided to keep it simple as I had never been to Gilly. I began my launch and waited until I got to my ejection angle then burnt for roughly 1km/s until my orbit was dipping through Eve's. That's funny I thought, I had Eve selected as a target and didn't even get a closest encounter marker. I played around with some maneuver nodes until I got an encounter. I had a 350km encounter, perfect for aerobraking and I would need to as my orbit had me nearly hit the sun after the Eve encounter. This happens nearly every time I try to get to Eve, I either have to sundive or just wait until I get captured. I have no problem getting to Jool or Duna or even any other inclined bodies like Minmus. Does anyone else always have trouble with Eve? Does anyone else seem to always have to sundive to get to the inner solar system?

Are C6-x Rockets considered large in Pre-made motors? My only experience with rockets is KSP and a few videos from real life and a couple model rockets I got for my birthday. One day I decided i would make my own rocket and I figured an Airhogs Titan glider would be a good body. I went out and I wasn't really up to date with the rocket sizing and grabbed a pack with the highest letter and number. Some tape and wires later I launched a rocket with two c6-5s on it. I had always figured they were still pretty small. One of the model rockets I got was actually an Alpha 3 and I've recovered it a few times after launching it from an acreage. I enjoy the stuff you can buy and throw together in a few hours but I don't think any will come close to modifying a 10$ foam plane into a rocket that flies over 300m powered.

How big of a problem would board layout be when we have to deal with heat and all? Since PCB is a better heatsink than the vacuum around the chips would they all end up overheating each other from the heat they take in from the sun and the heat they generate?

Last time I checked we were aiming for a cost around 10 - 25 thousand.

Would we be able to supply an Amp? What kind of voltage would we be looking at?

Will such a low cost processor be able to support 2 Cameras? Will we have to have some sort of secondary chip just for handling image processing?

This is starting to Co, e together pretty good. I never would have expected to use a 10$ cpu on a space mission. What type of battery and capacity would we want? I suppose we need to get components together first to check power consumption but a general estimate wouldn't hurt.

Earlier you said we may need to balance the stuff inside to prevent it from wobbling. What level of balance would we need? Would the weight at each end depend on the chips on the boards or could we be a dozen or so grams off?

I think it may have been a tad bit too early to collect funds. Once we do a kickstarted I'll probably go around and explain the mission to the science teachers at my school. I'm sure they would be willing to donate and help fund the cubesat.

That could be part of the test. We could see how long plants last up there or if they can survive at all.

Haha I did that on my phone and while I used to be a strong advocate of its keyboards I much prefer my tabpro for long messages. It took me a bit too long to realize my mistake though. I hope we get a lunch from a p-pod on the ISS.

Would a mission like this require deployable solar panels? They wouldn't offer much of an advantage over fixed ones unless our rotation was perpendicular to the sun so we could have as many as 3 panels gaining power at once.

That's fine. We need to decide on hardware now. We need things like high quality batteries and computers. Solar panels are important too. Edit: I would go with acrylic. I've tried making plexiglass cases for stuff larger than .5u and it's pretty hard. I agree that testing rad effects on plants and bacteria would be part of the experiment.

I thought we were generating the artificial gravity simply by spinning up the cubesat to 30 rpm like k^2 said. Edit: we are effectively using .5 u for electronics because the jar will take up half the sat.

Are you sure all of this will fit in a .5u stack? Do we have any estimates on the weight of some components we could use?

My science teacher and his wife are biologists. I don't k ow how experienced he is but I'm sure he would be happy to help out. What kind of data would we even be able to collect without bringing samples back?

If we aren't using parts specifically for cubesats we should use something easy to develop for. My personal pick would be the raspberry pi compute. http://www.raspberrypi.org/raspberry-pi-compute-module-new-product/ it's pretty compact and dependable. I'm sure we could do it with something like a Picaxe chip but then we would need to do lots of coding and such ourselves. The pi compute is pretty much a little computer. I don't know about its power consumption though.
