Side view of the Solar Orbiter spacecraft. Inside the gap between the outer part of the heat shield and its base on the right-hand side, the feed-throughs of the remote-sensing instruments can be seen. Two of the four corners of the heat shield have cut-outs for the SWA/HIS (top) and SWA/PAS (bottom) sensors. The white panels on this −Y side panel of the spacecraft are the spacecraft-provided payload radiators (SORAs), and the two-telescope unit near the top edge is EPD/SIS.
