Something from the bucket list

They had me from this scene!

I want to be standing there, ready to launchhttp://bit.ly/1P0mjBp

The CubesatA form factor designed in 1999 at Calpoly, 10cm x 10cm x 10cm satellite, launched from a Poly Picosatellite Orbital Deployer (PPOD)

iTelescope.net - telescope sharing network

nanosat eye in the sky concept - a telescope in space

The image is transmitted to satnogs, recombined and sent to itelescope

The payload ● Current concept - schmidt cassegrain design

○ 80mm Diameter ~ 1.5 arc second resolution.

○ ~ 40mm focal length.

○ is it enough?

● membrane telescope:

● 3D camera in space?

Spectral Analysis?

We need you!Construct a 80mm cassegrain OR 80mm dobsonian telescope to be the payload of the cubesat

We’re also looking for people to help outMathematicians: help us understand orbital mechanics, spacecraft dynamics

Astronomers: help us understand how to design and build the payload

Hardware designers: lots of electronics to build

Mechanical Engineers: How do we fit it all in? manage vibrations? thermal?

Web Developers: integrate data, command and control app, share data out.

Aerospace engineers: inject some good space engineering knowledge.

Fundraisers: I estimate $150k in total….

Legal: Who is going to regulate this? What hoops/risks/liabilities/responsbilities

Marketing: keep the story out there, attract talent, investors, sponsors, etc.

Community: YOU - get involved, help out, help us connect to the right people.

Hackerspace: we’ll need to build soon - where to gather?

Matlab license: so we can simulate our control systems
