Money from advertising is great way to fund spaceflight activities. Have you investigated going after advertising dollars in larger chunks via a modified PongSat mission?<br /><br />Ping Pong Balls (henceforth PPB) are pretty much vendor-generic -- or at least I don't know one manufacturer from another. However, IIRC from my childhood -- a golfball (once sliced open) consists of a shell very similar to a PPB wrapped around what looks like a bunch of rubber-bands formed into a ball. Discard the chewy center and you have the basis for a GolfBallSat... Said GolfBallSat flight is then a candidate to be subsidized heavily by Titleist, or Dunlop, or MaxFli, or Nike, or Prostaff, or... whoever returns your phone call with an interest and a dollar figure.<br /><br />If such a mission were to be investigated and a backer found -- try to contact some prominent golfers -- Tiger, of course, but others too. See if they'll autograph a few balls for you to be sent (still with their chewy center in this case) on the mission. Once back on the ground, they can be auctioned on your site and/or eBay. If the entire set of balls (presumably of the main backer's brand) is printed with the JP Aerospace logo and the mission name (

The increased size makes for much fewer satellites, of course, but presumably more capable as well. However, I've seen (although I've never bought any, so dunno if they still exist) half-size cans in grocery stores. Couldn't say what the capacity was -- possibly 4-ounces? Even with them, you'd still only get a third or less the number of satellites on-board as PPB, but it still might be worth it.
