Science Center - STEREO-A and L1 missions

This tool shows the location of the STEREO Ahead spacecraft relative to Earth and various missions at the Earth-Sun L1 point during the close approach of the STEREO Ahead spacecraft during the summer of 2023, an event also known as inferior conjunction. The top panel looks down on Earth’s orbital plane in Geocentric Solar Ecliptic (GSE) X and Y coordinates. The Sun is to the left of this plot. The middle panel shows the elevation above or below the ecliptic plane, in GSE X and Y coordinates. The last panel shows the view looking along the Earth-Sun line, in GSE Y and Z coordinates.
