This investigation is named after John Herschel, whose observation of Halley's Comet's tail led him to hypothesize the presence of a "repulsive force" known today as the solar wind. The HElium Resonance Scatter in the Corona and HELiosphere (HERSCHEL) program is a multi-year effort to design, fabricate, test, launch and analyze data from novel instrumentation on a suborbital rocket.

The scientific objectives of the HERSCHEL II mission are to: 1) Investigate the origin of the slow solar wind; 2) Investigate the variation of helium abundance in the coronal structures (a) departures from primordial composition (b) fractionation region for helium in the solar atmosphere; 3) Facilitate future investigation of Coronal Mass Ejections (CMEs), kinematics, and solar cycle evolution of the electron, proton, and helium corona.

The Principal Investigator is Dr. Tun Beltran/Naval Research Laboratory.
