Starfish Prime caused six or more satellites to fail, as radiation damaged their solar arrays or electronics, including the first commercial relay communication satellite, Telstar, as well as the United Kingdom's first satellite, Ariel 1. Detectors on Telstar, TRAAC, Injun, and Ariel 1 were used to measure distribution of the radiation produced by the tests. In 1963, it was reported that Starfish Prime had created a belt of MeV electrons. In 1968, it was reported that some Starfish electrons had remained for 5 years. Starfish Prime Starfish Prime was a July 9, 1962 high-altitude nuclear test conducted by the United States, a
Asexual reproduction in starfish generate new individuals in this way. He thought the arms might be shed by autotomy. In the same year, Monks showed experimentally that the "comets" developing from the severed arms of "Linckia columbiae" could indeed grow into new individuals. "Linckia multifora" and "Linckia guildingi" are two species of starfish found on Hawaii which were found to exhibit autotomy, shedding one or more arms frequently. The arms are known as "comets" and can move about independently and each one can grow into a new individual. Though severed from the nervous system and the water vascular system they still exhibit normal behaviour
