X-ray emission from solar wind charge exchange (SWCX) arises in the Earth's exosphere and throughout the solar system in the heliosphere. The intensity of SXCW emission observed by X-ray telescopes from within these emission regions varies a great deal, both as a function of viewing geometry and solar activity. SWCX accounts for much or most of the soft X-ray background (SXRB) but distinguishing it from Galactic emission is a tricky problem. One approach is to measure the SXRB at a given point on the sky at different times and with different lines of sight through the heliosphere. The Chandra Deep Field-South, comprising 52 observations and 4 Msec of data collected between 2000 and 2010, is uniquely suited for such studies. This talk will also discuss the potential of high-spectral-resolution observations and prospects for measuring mass-loss rates around other stars from their charge exchange emission.
