Interplanetary cubesat mission proposalshttps://icubesat.org/archive/2017-2/icubesat-program-2017/
This SpaceNews Article where Arianegroup sounds the alarm bell about the possible Hydrazine ban.I'm sorry Arianegroup you should just invest some more in thruster development!The article is contradiction with Bradford ECAPS. And there is also LMP-106, and the USA one. (It's true these have to be pre heated.)And lets not forget HTP (that was competing with hydrazine form the start).HTP - hydro carbon could be a replacement for toxic bi-propallent hypergolics. (Or Masten's MXP-351)This was also a bit stupid in my oppinion: SpaceNews, Arianegroup .. smallsat standardisation.... The larger segment is already standardized:Cubesats 0.25-16U (pocket cubes 1-4 P) [a loaded 12U/16U cubesat deployer ~32.5kg]Here they have a point: ~30kg (or a 12/16U box); 50kg (or 100lbf/45kg); 75kg ; 100kg (or 90kg/200lbf)ESPA 15" ring; 180kg (400lbf) ESPA Grande, 24" ring; 300kg (660lbf)OneWeb sat's as well as SpaceX sat's will indeed become standard busses. Let's add this chart I made with a list of small sat buses.Indeed the NORSAT's were troublesome, but it's strange GLAVCOSMOS/ECM could launch them without trouble.
