Just out of curiosity what would a reasonable estimate of the launch costs be
for a P3E class satellite ?

Mark:
Back in 2008 when we last seriously looked at this, the cost of launching a
satellite into a Geosynchronous Transfer Orbit (GTO) of the size/weight of
Eagle or P3-E was $8 million. Today that figure is more like $10 million,
though Peter, DB2OS (President of AMSAT-DL) probably has a more accurate figure
than this. Even so, the cost to launch is what makes things prohibitively
expensive. Raising that kind of money (plus the cost of the spacecraft itself)
is not viewed as viable given the results of our past fund raising efforts.
The last HEO launch was for P3-D/AO-40. Please keep in mind that the money
that was passed through AMSAT-NA totaled over $2 Million for P3-D/AO-40, from
1993-2000 (seven years) with considerable help from individual donors, ARRL
matching donor program, AMSAT-UK, etc. Other organizations, such as AMSAT-DL
and JAMSAT also had their own fundraising efforts as well in support of those
aspects of the program that they were handling. AMSAT also developed the SBS
(Specific Bearing Structure) as part of P3-D program that became the "frame"
that housed P3-D on the launch vehicle. At that time, we believe we had pretty
much "maxed out" what might be raised from within the amateur radio community
in North America. Unfortunately, that considerable fundraising effort wouldn't
get us 20% of the current launch costs. Clearly, we must expand beyond the
amateur radio community to raise funds of this magnitude, but to do so requires
both a non-amateur radio "vision" to what a HEO sat!
ellite would provide (e.g. excite non-amateurs) as well as a "Case for
Support" that would attract major donors, such as foundations. To date, we
have not been able to put together a plan that would meet these expectations.
Needless-to-say, given today's costs, the launch economics is the major
inhibitor, and not necessarily the cost of building the satellite itself
(though that also costs "real money" depending upon size and features and
whether major systems, such as propulsion are donated as was the case with
P3-D).
So, let's look deeper into the launch cost environment to determine what AMSAT
might be able to "afford" under current circumstances:
The cost to launch a "microsat" (e.g. a 9" x 9" x 9" structure such as AO-51)
was estimated in 2008 to be around $350,000.00. That is why we opted for a 1u
cubesat (4" x 4" x 4") back in 2008 as replacement satellite for AO-51-- we
couldn't afford the launch of a microsat given our finances at the time and the
concern about being able to raise the funds to pay for a launch that would
likely increase in cost of time.
To put this further in perspective, as I recall, back in 2008 the cost to
launch a 1u cubesat was around $60-80K to place a cubesat in LEO. The current
cost is about $120K for 1 Kg of mass to LEO (a cubesat is 1.1 Kg). The doubling
of launch cost is due in part to the significant interest in cubesats by the US
Government, aerospace firms (Boeing, for example), and others who have "real
money" to place cubesat payloads in LEO. Clearly, as Tony, AA2TX (AMSAT's
VP-Engineering) pointed out to me, the cubesat has evolved from a university
"novelty" to a standard spacecraft specification. This cost increase is the
reason why AMSAT applied for an ELaNA grant in 2011 (we were selected in 2012)
and where we will continue to apply for ELaNA grants in order to be able to
"afford" launches. Clearly, it make much more sense to focus on dollars
donated to AMSAT for spacecraft development rather than launches if we can get
"others" to support our launch costs.
BTW, "Aviation Week & Space Technology Magazine" had a series of articles in
the 30 JUL 12 issue ("Small Satellites: Doing More with Less") which
highlights this evolution, including cubesats, such as TechEdSat that will be
the first US cubesat to be deployed from the ISS using the same deployment
scheme (JEM-SSOD or Small Satellite Orbital Deployer) as the Vietnamese student
F-1 cubesat that will be deployed this week. Information about TechEdSat may
be found here:

Coupled with the launch costs is the "justification" for launches. NASA and
others (such as the National Science Foundation) will support launch
opportunities if the proposal meets THEIR strategic goals. Consequently, the
most effective way to "hitch a ride" is to put something in an amateur radio
space frame that meets their expectations, such as a scientific/educational
payload and/or provide "educational outreach." For example:
1. ARISSat-1/Kedr deployed by RSC/Energia from the ISS in August 2011 with a
student scientific payload developed by Kursk State University. AMSAT
developed ground based software to capture telemetry from both the satellite
and the payload, with amateurs forwarding captured data to a central server.
ARISSat-1/Kedr was considered to be a "prototype" for deploying student
payloads. Education outreach was also part of our efforts with ARISSat-1,
where, for example, telemetry data is available for student analysis. Whether
there are future opportunities for more ARISSat deployments remains to be seen.
2. AMSAT-UK developed FunCube (funcube.org.uk) under the model where
educational outreach is the justification (to be launched in 2013). The
satellite has received financial support from the Radio Communications
Foundation and is being developed in collaboration with ISIS-Innovative
Solutions in Space BV (a Dutch small satellite company that is a spin-off from
Delft University of Technology). AMSAT-UK is developing ground-based software
with an easy-to-use receiver (FunCube Dongle developed by Howard Long, G6LVB)
to encourage use of the satellite in the classroom.
3. FOX-1 will have a student scientific payload (MEMS Gyro originally
developed by Penn State-Erie students) as justification for NASA to pay for our
launch under the ELaNA grant. Ground-based software for capture of satellite
telemetry and payload data is also being developed using a central server for
data to be forwarded. AMSAT is also focused on creating education outreach
materials focused on Fox-1 that will be appropriate for future missions as well.
4. The appointment of Mark Hammond, N8MH as AMSAT's VP-Educational Relations
and the subsequent work that he is doing to develop relationships with outside
organizations (including ARRL and NASA Education), develop an "educational
outreach" capability in support of AMSAT's scientific and education mission,
and work to foster support of "STEM" (Science, Technology, Engineering,
Mathematics) as part of more traditional engineering work on space craft is in
recognition of the fact that we are dependent upon the support of other
organizations to be able to afford to fly. "Education outreach" is the new
"cost" (one that AMSAT can hopefully "afford") that we must bear to keep
amateur radio in space.
Clearly, it is launch costs that is driving much of what AMSAT can afford to
accomplish. In addition, we must recognize that those that pay for the launch
will only do so if the satellite provides a benefit that meets their
goals/expectations. Clearly, future opportunities for placing amateur radio
transponders in HEO will be dependent upon finding partners who have a need to
place THEIR payload(s) in those orbits AND have the major funding to support
the launch. In essence, that is what AMSAT-DL attempted to do by persuading
the German government to fund P3-E as part of a larger mission to Mars.
Unfortunately, their attempts did not pan out.
BTW, we'd be happy to accept your $44.00 to renew your AMSAT membership; you
can renew online at www.amsat.org... ;-)
