Rank 95 documents the Advanced Composition Explorer — NASA's primary upstream solar wind sentinel parked at the Sun–Earth L1 Lagrange point since August 1997. ACE carries nine instruments including SWEPAM, MAG, and EPAM that measure solar wind speed, density, and magnetic field orientation in real time, feeding NOAA space weather alerts that protect power grids, satellites, and astronauts. Edward Stone and Norman Ness led the Caltech/Goddard mission that reached L1 within three months of a Delta II 7920 launch and has transmitted continuously for more than twenty-five years — a heliophysics endurance record that pairs naturally with WIND as the twin solar wind laboratory of the 1990s. Wallimilist renders the six-sided bus, SWEPAM Faraday cups, gold L1 orbit arc, and streaming particle lines exactly as the master PNG dictates.
