Use a hash tables of Morse to translate sensor readings then burst the signal. While near the sun, solar cells should help, but you'll soon need an RTG (radio isotope thermoelectric generator) or you could try my design , which uses tritium light tubes held close to solar cells. You can salvage emergency exit signs for the tritium. You could possibly build an rtg using a beta emitter, not as powerful but youd probably save a bundle and your family jewels developing the unit in your garage! While the rocket part is cool, recharging the batteries far from the sun would be a problem. Even an rtg is good for like 10 yrs, getting weaker each year. You'll have a...
