Opportunities for collaborative science with Solar Orbiter

This page outlines how the orbital configurations of STEREO and Solar Orbiter can contribute to collaborative science between the two missions. The remote sensing instruments on Solar Orbiter primarily operate during three 10-day windows each orbit, with one window coincident with perihelion, and the other two aligned with the period when the spacecraft is at maximum North or South heliographic latitude. However, the scheduling of these three windowss is flexible, and can be adjusted to maximize the scientific data return. For the purpose of this analysis, we have examined the cases with nominal observing window placement. Along with these three observing windows each orbit, we also examine encounters with the planets Venus and Earth used to shape Solar Orbiter's orbit.

Unlike Parker Solar Probe, the remote sensing telescopes aboard Solar Orbiter are designed to image the source regions of the in situ material sampled by the spacecraft. Telescopic data from STEREO, when combined with those from Solar Orbiter, can give a stereoscopic view of these source regions. Also, it should be noted that the in situ instruments on Solar Orbiter will be operating throughout its orbit, and STEREO observations can be useful during these times as well.

Other connections can also be explored through the STEREO Orbit Tool.
