 By the mid-1950s, the concept of Ashtar and a galactic law enforcement agency preparing an imminent rescue of humanity had become well-established, and included various well-known, esoteric channelers of the era.For instance, Elouise Moeller predicted that a space fleet would arrive in the near future; and Adelaide J Brown claimed that flourishing civilisations existed on the other planets in the solar system.However, as time and scientific knowledge progressed, the public failure of these predictions had an enormous negative impact on the expansion of the Ashtar Command movement due to the lack of a central authority that could undertake damage control.
