Something from the bucket list
They had me from this scene!
I want to be standing there, ready to launchhttp://bit.ly/1P0mjBp

We need you!Construct a 80mm cassegrain OR 80mm dobsonian telescope to be the payload of the cubesat
![Page 21: Nanosat eye in the sky Astronomy Society of Victoria](https://reader031.vdocument.in/reader031/viewer/2022030309/58f1f7fe1a28ab6c358b45a3/html5/thumbnails/21.jpg)
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
