Barium and Lithium Release Modules

NSSDCA ID: 1978-098B-01

Mission Name: CAMEO
Principal Investigator:Dr. James P. Heppner


This investigation consisted of a sequential release of four barium cannisters and a single long-duration lithium release from the orbiting second stage of the Nimbus 7 Delta launch vehicle. The barium releases occurred October 29, 1978, along a track north of Alaska (79N to 74N). The barium was observed by many ground stations and was tracked from release at about 900 km out to about 5 earth radii during a one-hour period. The lithium release lasted for 50 s over southern Sweden on November 6, 1978. Observations of the neutral and ion clouds were observed optically be various ground sites.
