Lars Block (1925–2002)



Lars Block, a pioneer in space plasma physics, died on 25 July 2002 at age 77.

He will be remembered for important scientific contributions in areas ranging from plasma experiments in both the laboratory and in space, to theoretical research on fundamental plasma physics problems. His laboratory experiments were aimed at cosmic plasma physics problems such as modeling solar wind interaction with celestial bodies and anomalous interaction between plasma and neutral gas. His experiments in space were focused on electric fields above the aurora, and he played a key role in the Swedish space program, especially in the Viking project.
