Heliophysics Heritage — 2 museum-grade prints that set the mood. Parker Solar Probe honors Eugene Parker, who in 1958 predicted the solar wind that shapes space weather across the solar system — the first NASA mission named for a living person. Its in situ corona measurements address one of heliophysics' central mysteries: why the corona is hundreds of times hotter than the visible surface below. SOHO transformed solar physics from episodic rocket observations to continuous L1 vigilance — supplying the data stream that modern space-weather forecasting depends on. Its 1998 recovery after gyro loss became a case study in operator ingenuity.
