Tony, Thanks for giving this some credence. Although AMSAT is a supporter of ARISS, We are NOT ARISS. There are members of our group that assist with decisions and actually supply some of the required gear. ARISS must stand for an educational aspect working along with the Astronauts. Yes, the ARISSat project seemed to be turned into an add on by the other users of the International Space Station but hopefully will be redirected back into what it was intended to do. This should have been done a while ago and now we are in the summer hiatus of American schools and hopefully will be functioning at the opening of the school session later this year. See ANS 184 for update on this. Let us insure that the AMSAT goals of future satellites are still primarily at the top of the list. It is because of volunteers like Tony that we keep activities growing. See you on the birds. 73, Dee, NB2F
Dear Friends,
It is important to understand that ARISS is not AMSAT.
From the ARISS web page: "ARISS, (Amateur Radio on the International Space Station) is a program that offers an opportunity for students to experience the excitement of Amateur Radio by talking directly with crewmembers of the ISS (International Space Station). Teachers, parents and communities will see how Amateur Radio can energize youngsters about science, technology, and learning. Speaking with astronauts and other crewmembers is a unique educational experience. ARISS would like to take this opportunity to involve large numbers of individuals, particularly youth, in technology and the International space program with the help of Amateur Radio."
The primary reason NASA supports ARISS is to promote their Science, Technology, Engineering and Math (STEM) education initiatives. This is also true of our Russian friends at RSC-Energia and the other members of ARISS International.
So, please excuse my bluntness here, but a transponder that is solely for the benefit of hams to contact each other, is just not going to "fly" as an ARISS project as it does not support the program mission.
AMSAT has supported the ARISS program because of the opportunity to put ham radio hardware in space, including ARISSat-1, without having to pay launch costs. These costs really are "astronomical." There is no chance we could afford put any hardware on the ISS without it being a part of the ARISS program.
P3E sits on the ground because it costs far more than hams could possibly afford to pay to launch it into orbit. AMSAT-DL has done a great job promoting the science mission aspects of P3E in an attempt to get government funding for it but so far, it has been to no avail. We certainly all wish them luck but realistically, it is a very tough environment.
The primary reason AMSAT is pursuing the Fox program is because we CAN actually afford the launch costs. Although the very tiny size of a CubeSat (4" x 4" x 4") makes it technically very challenging because we want to actually make contacts through it not just listen to it beep, you can be assured that it will not sit on the shelf for lack of a launch.
I hope this helps to clarify the situation.
The next AMSAT Journal issue will have a report on my recent participation at the Small Payload Rideshare Conference. Several of the presentations included ballpark launch cost numbers for small satellites. The numbers (like $10M+) are eyepopping to say the least. It is clear that AMSAT has to take an opportunistic approach and pursue all of the opportunities we can find for low-cost or free launches.

Dee,
Thanks. Not sure this a SAREX Project but will let them decide that.
My only thought is a new satellite must find a launch and launch money. MY proposal would get a ride to ISS with cargo. I am not minimizing the issues for placing ham satellite on ISS, but I think the concept has promise.
If Fox or P3E sit on the shelf for 5-10 years for lack of a launch maybe better redirected for ISS. Not my call, obviously.

Redirected to the SAREX group. I do not agree with all of these point, however, No standing program should be de funded to do these. Get another satellite up ASAP is AMSAT's main goal. 73, Dee, NB2F

After posting some thoughts a few days ago (RE: ISS, what the heck happened?), I have given the idea more consideration.
Proposal (ARISS on ISS):
- Install a 100-KHz transponder unit on ISS, with usual digital
beacon/engineering 2) It would run mode-UV 3) Installed internally in the ISS 4) Replace most of the current ISS ham radio equipment 5) Could be considered an upgrade/improvement to the existing ham radio on ISS 6) Use ISS power and existing ham radio antenna infrastructure (no solar panels)(no thermal requirements for space environ)(perhaps less radiation hardening) 7) Use batteries for stand-alone operation (recharged from ISS power) 8) Control commanded from ground (no intervention required by astronauts) 9) Local access for use of astronaut-hams 10) Provide emergency back-up comms for ISS (perhaps with a separate FM channel) 11) (perhaps) Use of existing ham-radio handheld on ISS on low-power to dedicated receiver which would activate astronaut repeater channel. 12) This FM channel could be used as FM ham repeater when not in use by astronauts (means world-wide monitoring for the astronauts as well as normal Leo FM activity) 13) Modular design for future upgrades and/or repair (easy installation by astronauts-plug*n*play) 14) Segmented pass-band to allow packet/APRS digipeating 15) Transmitters able to be shut down for eva and other critical missions either locally on ISS or from ground. 16) Perhaps a special Rx/Tx on ISS eva channel for cross-band repeat in event of loss of atmosphere emergency (help to sell the concept to NASA as a comms back-up). 17) No need for orientation (spin or de-spin), rad hardening, thermal structures (air-cooled), no propulsion, no launch requirements. 18) Easily maintained by supply from ground (repairs or upgrades). 19) Long-Life
Re-direct of either Fox or P3E efforts? (no launch requirement-rides as cargo to ISS)
