You have to have some command module to control unmanned vessel, i.e: Stayputnik Mk. 1 which is opened with Basic Science tech, if you are playing carrer mode.

  • I was using stayputnik mk 1 but it does not launch when I press space and when I right click on it, it show "spu no connection". Commented Dec 7, 2015 at 15:24

    Oh, it seems you are using "RemoteTech" mod, in this case you should refer to their docs, what I found here remotetechnologiesgroup.github.io/RemoteTech is: "You need to use an antenna that won’t break in the atmosphere to be able to control an unmanned rocket during atmospheric flight. The Reflectron DP-10, unlocked along with the Stayputnik probe core, is the earliest such antenna available."

    It says it should be under "Science Parts" after researching Flight Control. More details here remotetechnologiesgroup.github.io/RemoteTech/guide/parts
