* LUNAR TRANSPONDER PROPOSED *

==============================

Eduardo Sweet, LU7AKC, has proposed a lunar-based store-and-forward

digital transponder for relaying packet radio communications around the

Earth. This proposal would eliminate the short access times currently

experienced when operating through low-Earth satellites, such as the

Pacsats. Provisions for including a CCD imaging camera for video

experiments are also possible.

Proposed DigiMOON MailDrop commands:

S <call> Send message to <call>

S <call> @ <call> Send message to <call> at BBS <call>

SB <call> Send bulletin to <call>

SB <call> @ <call> Send bulletin to <call> at BBS <call>

J Display heard stations (with day/time stamps)

J xx Display last xx heard stations (with day/time stamps)

B Disconnect

Proposed type of station:

DIGIMN-0 Workable only by authorized control stations.

Used for DigiMOON control and management.

It only sends the BEACON.

DIGIMN-1 DigiMOON DIGIPEATER.

DIGIMN-2 DigiMOON MailDrop.

SOME DESIRED FUNCTIONS/CHARACTERISTICS:

Self adjusting output power, depending on current availability.

Automatic Kill on forwarded messages or bulletins.

Programmable message/bulltin expiration dates.

Unproto: MAIL.

Modulation: PSK.

Band: 144 or 432 or 1296 MHz.

BUENOS AIRES, ARGENTINA OCTOBER 10, 1991

TO: AMSAT (Worldwide) & ALL RADIO AMATEURS

Hello! We are very pleased to inform that we have almost resolved the

cooling problem, due to an idea proposed by Charlie (LU4DGN).

* TEMPERATURE *

===============

A very close friend of mine, Charlie (LU4DGN), have almost resolved the cooling

problem of the mooncraft. It's very well known that the satellites spin over

it's axis exposing the different sides to the sun in order to keep the

satellite's temperature.

Charlie has proposed to make a four leg support for supporting the

mooncraft, so it can spin over it's axis. The system is based on a

microprocessor controlled servo motor.

* ENERGY *

==========

We planned to use solar panels and Peltier cells in order to grab energy

from the sun and from the thermal difference between the different mooncraft

sides.

* LINK *

========

We've found that some 1200 MHz. satellite receivers have de-sensing problems

(10dB losses) due to received signals from different earth radars. We think

that the better bands for linking with the mooncraft are 430 MHz. and 2400

MHz.

"Project Artemis"

=================

While an amateur spacecraft to fly to the moon with the DigiMoon device is

out of the question, riding on a US, European, Soviet, or Japanese lunar

lander is possible. In fact, NASA is conducting studies right now for

"Project Artemis," a small, low-cost (in relative terms) lunar lander to be

launched in 1995 or 96.

I'm a professor of Aerospace Engineering and my area of specialty is

spacecraft design. In my senior design course right now, I have two groups

of students working on lunar landers along the lines of the NASA Artemis

proposal. I suggested to the students that they include some sort of

amateur radio payload, but they did not include one. Still, their work can

be useful as a reference in the future. I will be glad to send you a copy

of each final report at the end of the semester if you are interested.

The two-week long lunar night poses difficult design challenges for both the

electrical power and thermal control subsystems. Even if DigiMoon was a

separate payload in its own container, it would have to be designed to

withstand the very cold temperatures of the lunar night. Solar power works

well for the lunar day, but not for the night.

Pointing and zooming a camera would be pretty difficult.

Let me know if I can help. The best way to reach me will be by packet

through a satellite gateway. Good luck!
