AB: We have designed, built and launched into near-Earth orbit a Solar Mass Ejection Imager (SMEI) capable of observing sunlight that has Thomson-scattered from heliospheric structures of time-varying density. SMEI is designed to observe heliospheric structures such as coronal mass ejections, corotating structures and shock waves, to elongations greater than 90$\deg$ from the Sun. The instrument was inspired by the heliospheric imaging capability demonstrated by the zodiacal light photometers of the Helios spacecraft. The instrument makes effective use of {\em in situ} solar wind data from spacecraft in the vicinity of the imager by extending observations to the surrounding environment and back to the Sun. A near-Earth imager can provide up to three days warning of the arrival of a mass ejection from the Sun. In combination with other imaging instruments in deep space, or alone by making some simple assumptions about the outward flow of the solar wind, SMEI can provide a tomographic analysis of the heliospheric structures surrounding it.
