The "Nozomi" orbiter was a 0.58 meter high, 1.6 meter square prism with truncated corners. Extending out from two opposite sides were solar panel wings containing silicon solar cells which provide power to the spacecraft directly or via NiMH (nickel metal hydride) batteries. On the top surface was a dish antenna, and a propulsion unit protrudes from the bottom. A 5 m deployable mast and a 1 m boom extended from the sides, along with two pairs of thin wire antennas which measure 50 m tip to tip. Other instruments were also arranged along the sides of the spacecraft. Spacecraft communications were via X-band at 8410.93 MHz and S-band at 2293.89 MHz.
