A radioisotope containing heat source for use in artificial satellites and
space vehicles. The source is configured so as to have a low ballistic
coefficient allowing its random reentry into the earth's atmosphere at low
terminal velocities. The low velocity prevents burnup and allows intact
reentry of the radioisotopic fuel capsules. The heat source may typically
be configured as a flat rectangular panel through which empty cylindrical
channels are formed for lowering its weight and within which capsules
containing the radioisotope are disposed. Graphite may be used to form the
body of the panel.
