NASA’s Juno probe (Juno) accidentally discovered a strange phenomenon: the dust blowing out of Mars piece by piece moving rapidly towards the inner solar system, the Earth was “not spared”, some of which also fell on Earth.
NASA scientists were the first to observe the stars of Juneau, the capital of Alaska, when they found some unidentified particle streams, thought to be Juneau probe fuel leaks.
A closer analysis revealed that they were fine streams of sand falling from the probe’s solar panel. the NASA public document announcing the discovery laughed at itself, saying, “This expensive solar panel actually became the largest and most sensitive dust detector ever built on one side.”
Scientists previously knew there were many dust clouds surrounding the sun, presumably from distant asteroids that slowly funneled into the inner solar system region.
The study, published March 9 in the journal Journal of Geophysical Research: Planets, used cameras on the Juno probe to track the distribution and path of these dust storms and found that they actually came from Mars, with some of them also entering Earth’s atmosphere.
The dust accumulates on the probe’s solar panels, and the sand “fills up” and leaks out.
NASA Goddard Space Flight Center (Goddard Space Flight Center) principal investigator Connerney (Jack Connerney) said that although the sand is very fine and light, but they are large, fast, to 16,000 kilometers per hour to hit the solar panels, at any Time in the wear and tear of the probe, but fortunately the probe’s Solar panels are strong enough.
NASA said that with the discovery of Juno probe, scientists better understand the source and path of these cosmic dust, which helps to plan the route of future exploration projects to try to avoid these dust storms.
