Solar Orbiter boom and antenna deployments

Visualisation showing the deployment of various boom/antennas on the Solar Orbiter spacecraft. Initially, the first Radio and Plasma Waves (RPW) antenna is deployed. Then the boom hosting a suite of scientific instruments is deployed (MAG, RPW, and SWA to measure the magnetic and electric fields, and solar wind around the spacecraft). Subsequently, the remaining two RPW antennas are deployed. Finally, the high gain antenna dish is unfurled. In reality this sequence is spaced out over a 24 hour period.

Solar Orbiter is an ESA mission with strong NASA participation. Its mission is to perform unprecedented close-up observations of the Sun and from high-latitudes, providing the first images of the uncharted polar regions of the Sun, and investigating the Sun-Earth connection. Launch is currently scheduled for 5 February 2020 from Cape Canaveral, Florida, US.
