The Voyager-X is a spacecraft comprised of the Voyager-X Main Body and Voyager-X Antenna docked together. Once docked together, they form the Voyager-X probe. This spacecraft is used in Mission 15 and Mission 26. Due to the Voyager-X Main Body's low fuel margins, those two missions can be very difficult.
It also stores 6 batteries, and consumes 5 Power. The antenna uses 1 Power which is supplied by the main body's cells, and the spacecraft is self-sufficient with power. The cells can't be swapped out for anything else before launch, and it has no living quarters which makes it perfect for recovery missions in the Sandbox. The antenna can take photographs.
