Description
This small probe may look cute and unimpressive, but once it deploys its long-range antenna, it looks pretty much the same.
Its Ion engine is very efficient for a spacecraft this small, so it can go very far indeed, as long as something helps it get into orbit first, of course.
A stock rocket called Ion-Powered Space Probe. Built with 10 of the finest parts, its root part is probeCoreOcto.
Built in the VAB in KSP version 1.5.0.
