Re: Re: Useless CubeSats



Graduate students must contribute something new to the art to earn their
diploma and they can spend 2 years working on it. If we had something that
fit those requirements and were willing to donate time or money there may be
interest. The person to convince is the professor who would sponsor the
student.

What AMSAT will have that would interest universities the most would be
space on a HEO satellite. If AMSAT wanted to change the way it operates, it
might be able to interest a consortium of small universities to participate
in a future satellite project if it gave them some space on the satellite
for their projects. AMSAT could provide the mechanical platform, power
supply and assistance from experienced aerospace engineers.
