What color dieci ? <| sep |> I ' m not aware of any master list , but heres some worth noting . 38583 . msg 1579564 # msg 1579564 lists a bunch of smallsat launchers in development , mostly by startups a few established companies in there thoughPlanetary Resources and Deep Space Industries are both startups working on asteroid mining , mainly for orbital fuel production notably George Sowers has mentioned ULA is specifically looking at Planetary Resources to buy fuel from for ACES . IIRC both companies have test satellites already in orbit demonstrating various technologiesBigelow Aerospace and Axiom Space are working on space station modules , both for use as ISS additions and later their own private stations . Bigelow seems the furthest along here , they ' ve got BEAM already in testing on ISS and hardware in production for a B 330 launch in ~ 2020 Spaceflight Inc does rideshare launches a bunch of tiny satellites manifested on one launch , they ' ve got a couple different payload carriers flying already on various rockets from other companies , and their SHERPA platform can carry like 90 satellites at once . NanoRacks does satellite deployments from ISS and its various logistics vehicles . They ' re also hoping to install a commercial airlock there in a few years , and they ' re contracting with Blue Origin to manage payload accommodations on their suborbital flightsBlue Origin is doing suborbital launches and hopes to fly a crew next year . They ' ve got a reusable vertical landing rocket , they ' ve built the worlds first tapoff cycle engine currently used on New Shepherd , planned for use on OrbitalATKs new rocket and New Glenn , and proposed for use on VulcanACES , they ' re close to having the first American oxygenrich staged combustion engine done which is the apparent engine choice for Vulcans first stage , and they plan to build a reusable 5070 ish ton to LEO rocket by 2020 . They ' re also in negotiations with NASA to reenter the Commercial Crew programXCOR Aerospace has been working on a reusable crewed suborbital spaceplane , though development seems to have stalled . Now they ' re focusing on engine development , hoping to sell engines to someoneMasten Space Systems has been developing vertical takeoff and landing rockets for a while . Right now they ' ve got a contract with DARPA to develop a concept for the XS 1 launch vehicle , their design would have a reusable VTOL spaceplane as a first stage plus an expendable upper stage . They ' re also working with ULA to build a lunar landerupper stage combinationReaction Engines Limited is working on the SABER combinedcycle engine , that would start as an airbreathing jet engine and then transition to a rocket at high altitudes . They ' re hoping to use that design on Skylon a single stage spaceplane and hypersonic aircraft . They ' ve also got some more conceptual work going on with space tugs and interplanetary manned missions , but thats all contingent on Skylon working .
