John Batchelor and I welcomed Jim Cantrell of Vector Space Systems to discuss his new dedicated small launchers, his business market, rocket capabilities, 3D printing of certain rocket motor parts, launch sites, and customers.  During our Hotel Mars double segment, Jim introduced us to the two Vector rockets under development, the Vector R and the Vector H.  He provided us with the launch capability for each rocket plus he talked about being able to launch dedicated smallsats from either a polar orbit from Kodiak, Alaska or an equatorial launch from Launch Pad 46 at the Cape.  Additionally, he addressed possible downstream technologies for consumers to direct their satellite function via their smartphone.  Vector is also developing the capability to custom build smallsat constellations for customers.  John asked Jim about 3D printing.  Jim said they use it for making rocket injectors out of aluminum and that they will expand the use of 3D printing over time.  When asked about 3D printing their rocket fuel, he said their rockets were liquid fueled rockets.  Jim told us that use carbon fiber for much of their rocket structure.  Earth science came up in the discussion as Vector has a new agreement with ICEYE of Finland for smallsat Earth Science (
