The nuclear verification process employed in monitoring Iraq and other nations via NATO and the United Nations uses these satellite joint
detection systems (the NSA controls and tracks the data). Many articles concerning these satellites have already been written in specialty magazines
(Defense Science and Electronics-for one). Any attempt to bring a nuclear device into our country would be instantly detected (not to mention the
track of its mobile transport).
Once again, the major US media resorts to half-truths for the benefit of ratings: "Stay tuned for more on our impending annihilation!" their unspoken
If an internal nuclear attack ever occurs in this country without a major failure of our satellite assets...perhaps we should rethink just who the
enemy really is...
"The original Vela satellites were equipped with 12 external X-ray detectors and 18 internal neutron and gamma-ray detectors. They were equipped with
solar panels generating 90 watts.
The Advanced Vela satellites were additionally equipped with two non-imaging silicon photodiode sensors called bhangmeters which monitored light
levels over sub-millisecond intervals. They could determine the location of a nuclear explosion to within about 3,000 miles. Atmospheric nuclear
explosions produce a unique signature, often called a "double-humped curve": a short and intense flash lasting around 1 millisecond, followed by a
second much more prolonged and less intense emission of light taking a fraction of a second to several seconds to build up. The effect occurs because
the surface of the early fireball is quickly overtaken by the expanding atmospheric shock wave composed of ionised gas. Although it emits a
considerable amount of light itself it is opaque and prevents the far brighter fireball from shining through. As the shock wave expands, it cools down
becoming more transparent allowing the much hotter and brighter fireball to become visible again.
No single natural phenomenon is known to produce this signature, although there was speculation that the Velas could record exceptionally rare natural
double events, such as a meteoroid strike triggering a lightning superbolt in the Earth's atmosphere, as may have occurred in the Vela
They were also equipped with sensors which could detect the electromagnetic pulse from an atmospheric explosion.
Additional power was required for these instruments, and these larger satellites consumed 120 watts generated from solar panels. Serendipitously, the
Vela satellites were the first devices ever to detect cosmic gamma ray bursts." -wikipedia
In 1959, the US started to experiment with space-based nuclear sensors, beginning with the VELA HOTEL satellites. These were originally intended to
detect nuclear explosions in space, using X-ray, neutron and gamma-ray detectors. Advanced VELA satellites added electro-optical MASINT devices called
bhangmeters, which could detect nuclear tests on earth by detecting a characteristic signature of nuclear bursts: a double light flash, with the
flashes milliseconds apart. Using Radiofrequency MASINT sensors, satellites also could detect electromagnetic pulse (EMP) signatures from events on
"Several more advanced satellites replaced the early VELAs, and the function exists today as the Integrated Operational Nuclear Detection System
(IONDS), as an additional function on the NAVSTAR satellites used for GPS navigation information."-wikipedia
those satellites only detect after a detention tho haven't been able to find any info on detection systems pre detonation like the first article i
quoted said they have...
eit: my bad reread your question and I seem to have misunderstood it at first I am not sure if our nuclear detonations would be that detectable that
far out in space sorry...
