Currently those of us that are doing any work toward the project are self funding. We can take the sat thru the manufacturing stages with minimal cost. The current big $ items are solar panels, rad hard CPU, and Launch. After we have a sat in hand waiting on those 3 items we will go for some kind of fundraising project.

I setup a google apps for work account, so we can have @mossat.org email. It seems that I accidentally turned off the redirect from mossat.org to fourms.mossat.org Fixed now.

In this picture the Z axis will be the up/down axis. The solar panels will be mounted to the top. The satellite will spin about this axis. The rotation of the satellite will create the artificial gravity. Here is a view with a mock up sample container. Also note the frame in the photo came from cubesatshop.com - not advertising just giving credit where credit is due.

Mostly we are waiting on the consumption rates of the moss. So we can back figure the required initial atmosphere mass. As to the dishes. We will be designing a custom sample container that is air tight.

Mission Update. Moss: We are lining up moss experiments. The goal of these experiments is to gather the required data to design the test chamber that will be used in flight. Optics: Lens design coming along nicely. Other systems: On hold pending test chamber. Thanks to everyone for your continued support.

In an effort to get more organized it was decided to move discussion over to our own forums the link is here.

That link is http://forums.mossat.org

This is true. However I was envisioning a ratcheting system with only 1 way rotation. This could be used to very simply control position repeatability. What I wonder is can we gather that data thru some means that don't require a sensor in the capsule.

Well I don't know if this is applicable but I have an unlimited webspace server I am willing to donate to the cause. Also we should pick up a domain mossat.org is not taken

Don't beat yourself up. They dont need to look professional as long as they get the point across. Also I don't see anything wrong with your drawing. I agree on the threads. Also welding the lids in some way will be advantageous. If we go with sample containers then we can just prepare another batch and swap them out. No need to open and reuse.

The problem becomes seal length. one big ring with a removable top (at least one side needs to open) will have approx ~500mm of total seal length. One small breach anywhere along that will result in mission failure. Using capsules like the one below will give ~25mm seal length each. This will result in more total seal length 25*27=675 however if one seal leaks we only loose one sample. Rev A of the sample Another idea for holding them Another note with this arrangement from the top of a sample container to the far corner of the cube should be acceptable for camera distance. We may need to have the camera slightly offset to view in (not sure if this will be a problem)

The only problem I see with doing away with sample containers is sealing the larger container.

Well here is a drawing for a sample container. Mazon Del can you give your input. If this container is along the lines of what your thinking I will revamp my design at lunch.

So tomorrow morning I will draw up a petri dish with a OD of 1.5cm and a inside space 5mm tall Well I can answer myself on this one... that would put the camera underneath the sample. So I need to think about getting that camera inside.

So what kind of capsule are we talking about? Petri dish test tube smaller sphere
