It was here that he proposed the detection of nuclear testing by use of spy satellites, specifically the Vela satellites.

The original Vela satellites were equipped with 12 external X-ray detectors and 18 internal neutron and gamma-ray detectors.

Serendipitously, the Vela satellites were the first devices ever to detect cosmic gamma ray bursts.

As additional Vela satellites were launched with better instruments, the Los Alamos team continued to find inexplicable gamma-ray bursts in their data.

GRBs were first detected in 1967 by the Vela satellites, a series of spacecraft designed to detect nuclear explosions.

This was done to avoid the American Vela satellite to pick up the advancement and to avoid alerting the civil population inhabitant in the area.

Seconds later the Vela satellites, Prognoz 7, and the Einstein Observatory in orbit around Earth were inundated.

In September 1979 a Vela satellite collected evidence of a potential nuclear burst over the South Western Indian Ocean.

Data from the Vela 6 satellites were used to look for correlations between gamma-ray bursts and X-ray events.

The previous 41 double flashes that the Vela satellites detected were all subsequently confirmed to be nuclear explosions.
