In 2007, NASA launched a satellite tv for pc with a really particular mission into orbit. The Aeronomy of Ice within the Mesosphere challenge — in any other case referred to as AIM — was designed to observe night time shining clouds. One of these atmospheric phenomenon is of explicit curiosity to scientists as a result of it could not have existed earlier than the 1883 explosion of the volcano Krakatoa.
Because the challenge’s official web site declares, AIM’s “devices monitor noctilucent clouds to higher perceive their variability and attainable connection to local weather change.” Sadly, that mission could also be at an finish after 16 years of operation because of the satellite tv for pc concerned growing energy points.
NASA made the announcement this week. The satellite tv for pc going offline is the newest (and, presumably, ultimate) in plenty of technological points that started in 2019. The difficulty this time seems to be with the satellite tv for pc’s battery, and NASA will proceed to maintain monitor of its sign for the subsequent two weeks. Contemplating that AIM was solely meant to supply knowledge for 2 years, its prolonged lifespan is that rather more spectacular.
NASA introduced that knowledge from AIM has, through the years, been utilized in “379 peer-reviewed scientific papers.” As Engadget famous in its report on the satellite tv for pc, these included one current paper that linked noctilucent clouds to methane emissions. The AIM satellite tv for pc might now not be working, however the knowledge it yielded will proceed telling us extra about our world.
