The Manhattan Project -- Its Immediate Influences

With the Manhattan Project on the brink of success in spring 1945, the atomic bomb became an increasingly important element in American strategy to bring an end to World War II.

Because of the generally accepted view that the Japanese would fight to the bitter end, a costly invasion of the home islands seemed likely, even though some American policy makers held that successful combat delivery of one or more atomic bombs might convince the Japanese that further resistance was futile.  They contended that the bomb could...

The Manhattan Project -- Its Operations

Major operations for the Manhattan Engineer District (Manhattan Project) took place in remote site locations in the states of Tennessee, New Mexico, and Washington, with additional research being conducted in university laboratories at Chicago and Berkeley.

At the Metallurgical Laboratory in Chicago, Enrico Fermi's experiments at the CP-1 pile took place to determine the exact amount of neutron reduction needed for a safe and controlled sustained nuclear reaction.  A...

Powering Curiosity; Exploring New Horizons - DOE's MMRTG

DOE's RTG is doing it again. The Department's Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) is providing continuous power to the Mars rover Curiosity.  This radioactive power source is "essentially a nuclear battery that will operate the rover’s instruments, robotic arm, wheels, computers and radio. It is fueled with plutonium-238 that gives off heat as it naturally decays. No moving parts are required to convert this heat...

The Manhattan Project -- Its Establishment

On August 13, 1942, the Manhattan Engineer District, whose name was based upon the geographical location of its headquarters, was established.  In September, the Army appointed Colonel Leslie R. Groves to head the effort.  Groves held that the exigencies of war required scientists to move from laboratory research to development and production in record time.  Though traditional scientific caution might be short-circuited in the process, there was no alternative if a bomb was...
