The graphic below shows the timeline of events during perihelion 22 of the Parker Solar Probe.
For 11 days around perihelion, PSP collects science data but maintains radio silence. Data is downlinked once the spacecraft is about 0.25 AU away from the Sun.
During these 11 days, PSP is on its own, running instruments, storing data, keeping the shield pointed at the Sun, angling solar arrays to prevent overheating, thermal mgmt, ...
