I\nwould be really surprised if they would crack the hatch to toss a\nsatellite and remember that human space flight certification is not\nsimple. Might want to forget that idea too.\n\nIf NASA is going to the moon in 2010, AMSAT better have someone\nsubmitting proposals to the design team building the landers NOW! It\ntakes about 3-4 years to get through the process and you'll want to be\nfully integrated instead of a last minute add on that can also be a last\nminute removal. It will be a much easier road to be part of an unmanned\ncraft. Bob can tell you how much fun it is to certify hardware for a\nmanned space flight. Human spaceflight certification is not simple.\n\nHow do you aim the gain antennas once the lander is down? I presume it\nmatters greatly where the lander is on the moon as to how complex the\naiming mechanism will be.\n\nAs you state, power is the biggest challenge. Need to find that out soon\nbefore plans can really move forward. \n\nToo bad we didn't get in on the SELENE project from Japan\n(http://www.jaxa.jp/projects/sat/selene/index_e.html), we'd be in orbit\naround the moon now. \n\nKenneth - N5VHO\n\n-----Original Message-----\nFrom: [email protected] [mailto:[email protected]] On\nBehalf Of MM\nSent: Tuesday, October 16, 2007 6:47 AM\nTo: Ric Letson, NB2E; [email protected]\nSubject: [amsat-bb] Moon Missions are possible\n\n\n\nHere is my 2-cents.\n\nForgot about the rocket contest.  \nBuilding a rocket to fly and land on the moon is beyond most of our\ncapabilities.  The amateur radio community has very limited funds and\nonly ~2 million users world wide.  My suggestion for getting to the moon\nis to Piggyback on someone else's rocket.  Just like we have been doing\nfor years with Arian and Leo-sat applications.  Lets plan on going to\nthe moon without the contest.\n\nNASA is going to the Moon starting in 2010-2015 with Unmanned landers.\nSo, why build a rocket and lander when we can hitch a ride on the NASA\nlander.\nLook at all of the money we can save.  No rocket, No navigation, No\ncontrolled lander. All we have to worry about is getting a cube sat size\nbox to pass the tough nasa flight saftey requirments.  And we could have\nit running in 5 years or less from the moon.\n\nKeep It Simple Details.\n\nCamera:\nRe-use NASA existing lander cameras and use those to send back to earth\na few SSTV or digital images via Amateur Radio.  When ever possible,\nreuse existing hardware, do not redesign the wheel.\n\nTransmitter:\t\n\tA simple Mode B / J Transponder (2 meter and 440), for SSB/CW.\nSorry the moon is too far away for FM.  We can copy the Analog\nTransponder circuits for AO-10. \nThe A0-10 satellite is still running when it has good sun, so that\nproves the concept of the stable Analog circuit.  Avoid DSP and complex\ndigital circuits, Radiation will kill them.\nI chose Mode B and J becaue this is the most popular format, its what\nthe hams want!  We do not want GHZ!\n\nAntennas:\n\tIf possible try to reuse the existing antennas from\nthe Lander.   If not, then stuff on a pair of 9 dBd\nHelix loops.\n\nPower:\n\tHere is the hard part.  I still do not know what the plans are\nfor providing power to the landers.  If it's Nuclear, Great, we will\nhave power for 24/7. Solar panels would work for 14 days per month. If\nits battery only, we are kaput.\n\n\nAs for the contest, If some billion dollar university wants to take on\nthe project, Great.  The ham community can design the transmitter and\nfocus on what we do well and leave the rest to the billion-dollar\nuniversity.   \n\nOther deep space Flights:\nThere are some Russian companies looking into the possibility of\nMoon-Flyby-Tourist rockets.  Tourist can pay $50 million and then fly to\nthe space station.\n After a few days on the space station, they will then fly to the Moon.\nThey will not land; they will just do a few orbits and then return to\nearth.  Now we will have the opportunity to put ham gear on the Tourist\nrockets and maybe even toss a ham satellite out the door from Moon\nOrbit.\n\n\n73 Miles WF1F\n\nwww.marexmg.org\n\n\n\n \n________________________________________________________________________\n____________\nShape Yahoo! in your own image.
