Was the asteroid belt as dangerous as planners feared?
Pioneer 10 entered the asteroid belt on 15 July 1972 and emerged in February 1973, after a 435-million-kilometer passage. As the first spacecraft to cross the belt, it gave planners direct evidence about a region no spacecraft had traversed before[1][2]. Some impacts were recorded, but the hazard was much less than expected. The passage mattered because it replaced an anticipated danger with an observed, lower risk for a spacecraft crossing the belt[3].

The Mountain Ash Fish That Fell Alive
Transcripción
In Odd Showers, published in 1870, Sir George Duncan Gibb records a report of fish falling at Mountain Ash. The striking detail is that they were said to be alive. Newspaper accounts reported that some were still living and healthy when placed in bottles. Gibb considered whether a waterspout, or a hurricane, might carry fish from water and bring them down in rain. But he did not treat that explanation as certain. He noted that the fish landed on several house roofs, where such an event would have been noticed. And he acknowledged that their source remained uncertain. They may have come from fresh water, but their quick death in artificial seawater did not prove it. The report is curious; the cause, Gibb cautioned, was unresolved.
