[amsat-bb] Launch weight (mass) of Phase 3-E (Express)?

Hi Greg, That is hard to say exactly for sure as it actually has not been done yet. Maybe somebody else out there knows? I do know AO-10/13 was around 140kg at launch with fuel and is 90kg without fuel. So it would be significantly less as the fuel does weigh a lot (50kg?). Also a quick search shows that a 400N motor weights around 9.5 pounds, so minus that.Unfortunately that launch opportunity for the direct launch to a Molniya type orbit was scrapped. Hopefully AMSAT find some sort of a affordable launch opportunity for it here soon in the up coming years. It is difficult enough now a days just to get a 1-2kg cubesat into LEO unfortunately.
