    "content": "Jerry --\n\nI share your nostalgia, and I've never even been able to work a HEO satellite!\n\n But if you are asking this question in earnest, it has to be said\nthat even if we amateurs could compell the universities launching\ncubesats to do as you ask, the resources would not equal one HEO\nlaunch. Say a cubesat costs $80,000 to launch. If current HEO cost\nestimates are correct, and we're looking at over $10,000,000 for that\nlaunch cost, then we would need to harness the wealth of 125 cubesat\nteams just for the launch cost. I don't think any university is going\nto wait for that.\n\nThere is an oft-repeated misapprehension lurking under here, too, and\nthat is that the wealth going into the cubesat launches is money that\nwould otherwise be spent on a HEO amateur satellite. Cubesats are (in\nlarge part) university projects aiming to give students access to the\nprocess of designing, launching and controlling a satellite. They are\nattractive to granting agencies (and even launch agencies) because of\ntheir eduational potential. To my knowledge, during the design and\nlaunch of previous amateur HEOs, professors did not line up to apply\nfor grant money to hand over to AMSAT-NA or -DL, as they are now\nlining up to apply for money to build cubesats. Contrarywise, I don't\nbelieve many of these cubesats have made any demands at all from the\n(hobby) amateur community to defray their costs. (Perhaps this is not\nthe case in countries where the cubesat represents one of the\ncountry's first forays into space, such as Turkey.)\n\nIn short, there is no evidence that cubesat activity is in any way\nreducing our opportunities to go to HEO again. Other, currently\noverwhelming, factors are doing that all by themselves.\n\nWhat the cubesat platform has done, though, is offered a regular,\naffordable launch opportunity for low LEO. We members of this list\ncould probably muster enough money to launch our own satellite,\ndesigned here, and controlled by us, if we so wished! (I think at one\npoint JoAnne tried to start a thread along those lines.) You mention\nRS birds: could we deploy a 10m antenna from a 10 cm^3 volume?  Maybe\na spooled-out wire? What kind of propulsion can we make to get from\ncubesat LEO to something with a better footprint? In my opinion, if we\nreally are the descendents of the garage-engineers of OSCAR-1, we\nshould be buying up pumpkin cubesat spaceframes and posting videos for\neach other of the cool things we've achieved in that limited, but not\nimpossible, space.\n\nHere's some other ideas:\n\n1. CW robot (a la RS) in a PIC. Can you do it in a single atmel\natmega328? At 20 MHz? At 4?\n2. PIC code so that the bird turns itself off over unpopulated areas.\n(I love my solo passes over the Atlantic when I have VO-52 all to\nmyself, but I'd be willing to give them up for the greater good :-)\nExtra credit: have one chip do both of the above under a operating system\n3. Antenna testing: hang a cubesat model up 50' in a tree with some\nfunky antennas on it. Can you make them have the pattern you (we)\nwant?\n4. Propulsion. How much thrust can we safely get into a cube?\n4. This one is completly impossible, but boy it would be nice to have\na U/V transponder on a 10 cm^2 board. We'll have to wait years for\nsomeone to do that, though :-)\n\nWe really, honestly, still can have fun. Maybe not the fun that some\nof you had back in the day, but there's lots of cool stuff to be\nundertaken.\n\nFinally, in that spirit, can I encourage everyone to join in on the\ncubesat launches in a few days? Watch the launch, get on internet chat\nand eavesdrop on the excited conversation of these young people. Join\nthe global hunt for the proper keplerian elements for these birds, and\ncopy what telemetry you can. We almost all of us have the skills and\nequipment to be part of a remarkable event. I can't tell you the\nthrill of letting these people know their baby is alive and beeping in\nspace.\n\n73, Bruce\nVE9QRP\n\nOn Tue, Sep 15, 2009 at 4:07 PM, Jerry <[email protected]> wrote:\n>       Hi :  I guess you could say I miss AO-10   .
