what would be entertaining would be marketing the Phase 3 E bus or at least
parts of it to various educational institutions that want to do more science
then a cubesat can do...or maybe some place, like a lunar libration point
that a cubesat cannot go. the Mars thing is never going to happen but a
lunar probe might...the comm payload might have to be downscaled somewhat
but its a possibility Robert WB5MZO and S2 something soon

once a Life-member always a Life-member even if they gave up satellites
years ago and are now living in retirement homes. AMSAT-NA sold a large
number of Life-memberships in the 1970's at what now seems a very low price.
I believe the number of AMSAT-NA members who actually pay an annual
subscription is around 1500. A number of overseas amateurs are also AMSAT-NA
members, so the number of annual subscription paying US/Canadian members
will be less than 1500.

every single one of them would have to pay $833 a year, I just can't see
that happening.

there are possibilities however, SpaceX is going to do at least one full and
one semi test flight on the heavy...the semi test flight is for the USAF and
they are carrying ballast...and the final stage has to do a disposal burn RGO

What is realistically achievable with a 3U cubesat with an ion engine?
Cost of the satellite?
Cost of the launch?
Time/cost to develop ion engine?
How many month/years would it take for an ion engine to boost a 3U
cubesat from 600 km to 2000 km?
What is the altitude limit for an ion engine?
Impractical to slowly cross the radiation belt?
Could a 3U cubesat with deployable solar panels power a 1 watt, 100 kHz,
mode U/V transponder?
I would contribute $1000 to a fund raising campaign for a financially
and technically viable plan to (for example) launch in 3 years and
deploy a transponder in "high" orbit 2 years later.
I probably would not contribute to a fund raising campaign for a
whizbang 3U cubesat destined for a 600 km orbit.

Trust me, no one out there wants me to be more totally wrong about P3-E
than myself but my guess is that it will never ever see space. I want to
be wrong soooooo bad but I'm a realist.
