1990s heliophysics era — 2 museum-grade prints from the period. 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. Ulysses proved that leaving the ecliptic was essential for a complete picture of solar wind structure — equatorial measurements alone could not explain heliospheric dynamics. The Jupiter gravity assist that made the mission possible became a textbook case in interplanetary navigation.
