There are currently international treaties that bar the orbiting of atomic weapons. Negotiations
can be begun that would permit the orbiting of nuclear devices verified to be of an "Earth-Safe"
design. On this website I propose and give an example of an atomic explosive that is physically
incapable
The best place to put a system of missiles carrying atomic explosives for destroying or
deflecting incoming asteroids or comets is high Earth orbit. From high Earth orbit it is possible
to launch an intercept mission in less than 48hrs. From the Earth’s surface it could take weeks
or months. Ideally, there should be two groups of these devices in both equatorial and polar
orbits. A target coming from nearly any direction could be engaged from these two orbits.
Current designs for weapons require the use of chemical explosives to initiate and enclose
the preliminary chain reaction. Instead of explosives, the Earth Safe design for an atomic
explosive would use the speed and mass of the asteroid to assemble and detonate the device.
A high speed gas jet will assemble the critical mass and the impact with the asteroid will compress
the critical mass to a super critical mass. The device is designed to go critical and partially meltdown
upon entering the Earth's atmosphere. This will render it nearly inert and incapable of any significant
damage.(Unless you are standing where the pieces hit.)

Just before asteroid impact, a gas/plasma Cushion Generator is accelerated ahead of the main body.
The Cushion Generator is made from a material such as Lithium that will easily vaporize on impact.
The separation distance is dependent upon the asteroid’s speed and composition. The optimum timing
is to have the two parts of the critical mass come together just before impact.

The separation distance is dependent upon the asteroid’s speed and composition. The optimum timing
is to have the two parts of the critical mass come together just before impact.
The Cushion Generator will vaporize on striking the asteroid body and generate a gas jet. Ideally this gas
jet should be a gas without solids from the asteroid. The gas jet will drive the Highly Enriched Uranium HEU
core into the HEU shell completing the critical mass. The vaporized material may also act to cushion and
separate the device from the asteroid during impact.

The gas jet strikes and partially ablates the Copper Gas Jet Shield. The Copper Gas Jet Shield will drive the
HEU Core into the HEU Shell. The combined core, (shown in dark blue), is now critical and neutron
multiplication is now exceeding unity.
The critical mass is encased and sealed in by the Core and Shell Neutron Reflectors (shown in yellow). The
Compression Shells, (shown in purple), will maintain compression during impact. The X-Ray generators,
(the red tips at the rear), have powered up and are reflecting X-Rays from the critical mass to the
detector, (purple cone at rear).The detector will use the reflected X-Rays to measure the density of the
critical mass.

The super-critical mass (shown in light blue) has now been compressed by contact with the partially
excavated surface of the asteroid. The mass should be compressed to approximately 2.5X its normal density
to achieve optimum yield. The detector at the rear of the device (shown as a purple cone) will detect the X-Rays
being reflected by the super-critical mass. At the critical or peak density it will initiate a neutron pulse.
After 90+ generations the energy 90+ generations is approximately 1 X 10E-7 seconds. The Compression
Shells (shown as red/brown on the right side) will extend the period of time that the mass remains compressed
in a super-critical state.
While the critical mass is assembled, there is a small window of vulnerability where a stray neutron can
initiate a premature chain reaction. This would reduce the explosive yield. There may also be poorly
understood impact phenomena that could generate significant neutrons or radiation that could prematurely
start a chain reaction. The Core and Shell Neutron Reflectors, (shown in yellow), may provide some
shielding from unexpected impact phenomena and stray neutrons.

Alternatively, when the time to projected impact is short, it may be impossible to apply a sufficient

time item for incorporating such a device in a rocket system is the development of a container to
deliver the a meter in length and 35 cm in diameter, with a mass under 220 kg. The longest lead-
time item device and a fusing system capable of operating with the timing constraints required by the
spacecraft velocities near impact with the NEO. Specifications for a nuclear bus could be the
same as those for a kinetic-impactor mission, but would be very challenging to construct and
integrate with the booster rocket and the nuclear package in under a year. This “latency time”
between the decision to act and the launch can be reduced dramatically (perhaps 100 fold) by
designing and testing these critical components in advance of discovering a hazardous NEO.
