The Hope spacecraft will be a compact, hexagonal-section spacecraft. It will be built from aluminium in a stiff but lightweight honeycomb structure and surfaced with a strong composite face-sheet. Its overall size and weight are comparable to a small car: it will weigh approximately 1,500 kg including fuel, and measure 2.37m wide by 2.90m tall.
Once in space the craft will charge its batteries using three 600-watt solar panels. (For comparison, that is enough power to run around 20 laptop computers). The solar panel arrays will be folded flat against the sides of the spacecraft for launch, and will unfold once the spacecraft is in orbit.
