Launched in 1989, Project Galileo crashed the most
radioactive isotope of plutonium into Jupiter's
atmosphere last Sunday. Lt-Gen. Abrahamson, head
of SDI Org., at Albuquerque 1988 symposium: 
"Failure to develop nuclear power in space could
cripple efforts to deploy anti-missile sensors
& weapons in orbit." "It is reasonable to believe
that the real reason NASA launches plutonium into
space on these so-called 'civilian' missions is
as a COVER for their military launches of plutonium.
Without the civilian infrastructure for using
plutonium in space, military launches would require 
a whole lot of additional infrastructure, money,
security, & LIES." -R. Hoffman, computer programmer,

The European Space Agency uses solar power instead
of plutonium on these probes, such as their Rosetta.

This is the 1st intentional crash of a NASA
Radioisotope Themoelectric Generator (RTG) into 
a planetary atmosphere. "The heat generated by 
(Jupiter atmospheric) entry is most certainly 
intense enough for all the elements present to not
only reach melting but also boiling temperatures
within several seconds (including the iridium 
shield casing around the plutonium, iridium melting
point is 4435 degrees F.; Pu-238 melting point is
1183 degrees F.)."

NASA has been reshaping itself over the 1985 to 
present period to use its shuttle fleet as a service
for the orbiting nuclear power plants that are to
provide power for the laser cannons & particle beams
of Star Wars, says Dr. Michio Kaku, prof. nuclear
physics @ CUNY.
