The total design weight of the spacecraft is 279.3 kilograms or just over 614 pounds. Its size is about two meters across and 1/3 meter deep in a octagonal pattern. It will consume about 92 watts of power; less than that of a '100-watt' light bulb. This will be provided by a combination of solar arrays. On-board batteries will also be needed because the Earth will eclipse the spacecraft for up to 90 minutes during two times in the year at the Vernal and Autumnal Equinoxes.
