Ask Mazon Del (I guess he's in charge of the biology part of the mission) if it'd be useful to observe the moss with a camera/with a microscope/with special cameras (infrared, etc). What other aspects of it will we be monitoring? Keep in mind we want as much of actually useful data as we can.

CAMERA

NERVAfan and I think the GoPro would be best because they are sturdy, HD, and actually smaller in length than the other options... I wrote down their weights and dimensions on the doc.

ON AN UNRELATED NOTE:

I've just found the ISS only releases cubesats if their parts have already physically been to space and survived (in experimental flights). I don't know about brute launches but that's something we should keep an eye on.

Probably just regular life getting in the way. Happens all the time.

I think a stripped webcam would be our best option because we can add our own thermal control to it much more easily than something in a case like a go pro.

OK, OK Let's sort this mess out

Priority Number 1

Organize the project

Order of business

  1. Get a team together.
  2. Set up a roadmap.
  3. Determine responsibilities.
  4. Create a schedule.

We can only figure out the specifics of the work after we get this done.

It doesn't need to be military-strict, but we need some kind of tasks assigned to different people. Of course we'll be flexible and understanding if things don't go smooth, we're not exactly on a contract with anyone. We need to have a more cohesive group to start skype meetings or whatever. I mean, I want this project to fly, not just as a thought experiment. So I ask, honestly, who will join me?!

We should start a new thread only for this particular mission, this one's getting dragged.

How can we organize this project? There are some free project management software out there (bitrix24 and producteev)

IF YOU'D LIKE TO JOIN THE PROJECT MESSAGE ME be sure to add what you can/would do. No requirements besides enthusiasm!

No, seriously, even if you're good at nothing we'll accept you. We have plenty of vacancies.

I feel that we just started discussing with seriousness in the last few dozen pages. So 100 pages of dead weight. Also, this thread is misleading in the sense it gives the impression this is a thought-experiment on a Phobos mission. But that's just my humble opinion, of course.

Hey guys! I'm back!

Sorry about my absense for the last week or so. I've been swamped with a bunch of stuff related to work and my rover project (a submission in the NASA SRR challenge, I'll post pics at some point). We've been hitting a critical stage so I've been a bit distracted. I'm going to look through the backlog of pages to see what I've missed.

So as far as the plants and camera. If we do have the experiment exist in total darkness with sucrose providing the energy to the plants, then it was recommended by the biologist professor that we utilize an IR camera for the microscope. Though as long as long as the lights were on for only a few seconds it might be fine to go with normal visible light.

Great! Do you want to be added to edit-able list? I'd need a gmail in that case.

I'll set up a gmail account in the next couple of days then.

Well... best of the cameras listed in the doc. There might be other good ones I don't know. I'm not a camera expert - but the other ones listed are a real stretch dimensions wise.

Near IR or thermal IR?

http://www.goelectronic.com/SONY%20XCEI50.html?source=googleps&gclid=Cj0KEQjwiJiiBRDh3Z-ctPfS5MgBEiQAAlkbQip0tMNd2_3M3WBkNpxGc7ycf5jJfEYv5FCUR13jgNUaAikE8P8HAQ Needs a near-IR light source (LED suggested). 50 or 60 grams (page is inconsistent). 29 (W) x 29 (H) x 32 (D) mm. $589.95

Thermal IR: http://www.optris.com/thermal-imager-pi160 195 grams. 45 mm x 45 mm x 62 mm. 2,960 Euros and up (ouch).

FLIR makes tiny thermal IR cameras but I don't know how expensive they are.

Is it going to be total darkness? On second thought, that'd probably be easier for luminescence control (rather than 45 min spinning sunlight 45 min total darkness). I think he means IR as a method of nightvision that wouldn't affect plant growth. But in that case we'd need and IR light up there. What wavelength is the least absorbed by the moss Mazon Del?

I would need to check about the wavelengths, but I do believe that the LED illuminated near IR that you brought up NERVAfan is the acceptable method. Though I am uncertain this camera would be a suitable item, mainly because the things it is going to be looking at are going to likely be centimeters (or less) away from the lens.

I have been advised that total darkness will work best for the moss. We provide it with a sucrose alotment and the moss will happily matabolize it without access to sunlight. The gravitometric response is more exagerated in dark environments for some reason.

Great, we're waiting for the info, Mazon!

Now, I just had an idea that'd be most useful later on. Everyone should state their timezones and latitudes, even if general. If you're afraid of giving you coordinates, a city would be enough. This is to know when each person is reachable and how opportune their global position is to this project (tracking and all that). I'll just go right ahead and post mine now!

I assume that is because the moss would try to grow towards light as well as away from gravity if light were present. Where has K^2 been, the first post still hasn't been updated and that is beginning to irrationally bother me.

That only goes up (or down) to -20 degrees. Are you sure about that? And The main chip that we're going for's probably gonna cost somewhere around 20k. The amount of money we have will almost entirely depend on how much crowd funding we get. Hype = crowd funding. Good looking and reliable plans = hype. so basically what we're doing here is planning what to do with the cubesat, which is essential, but technically, the better looking and reliable our plans are, the more crowd funding we get.

(Ignore all of this if we are getting funded from NASA. sorry, been away for a while.)

The moss can't really go below freezing though*. So if the moss can survive then it should be fine.

*Even if it can theoretically survive below freezing (depends what species we use) it probably won't grow well (or at all) if it gets below freezing every 90 minutes. On Earth the day/night cycle is a lot longer.
