The apparent toxic effects of lunar dust were never comprehensively studied after the program, and the concentrations of dust that contaminated the spacecraft are not known. In each case, symptoms resolved within 24 hours, and post-flight pulmonary testing found no permanent impacts in the astronauts.
Lunar horizon glow is a phenomenon in which dust particles in the Moon's thin atmosphere create a glow during lunar sunset. The Surveyor program provided the first data and photos of the phenomenon. Astronauts in lunar orbit observed it during the Apollo 15 and Apollo 17 missions. Lunar horizon glow as observed by Surveyor 7 mission.
Moon dust is an extremely abrasive glassy substance formed by micrometeorites and unrounded due to the lack of weathering. It sticks to everything, can damage equipment, and it may be toxic. Since it is bombarded by charged particles in the solar wind, it is highly ionized, and is extremely harmful when breathed in.
(By the way, don't Google "Apollo 11 images" unless you're prepared to sort through pages of fake moon landing conspiracy websites.) The most famous one is this iconic picture of Aldrin below.
The box-like machine was now ingesting small quantities of a dusty regolith – a mixture of dust and sharp grit with a chemical composition mimicking real lunar soil. Soon, that regolith was gloop.
Lunar dust or regolith is the layer of particles on the Moon's surface and is approximately <100 um. [21] The grain shapes tend to be elongated. Inhalation exposure to this dust can cause breathing difficulties because the dust is toxic. It can also cloud astronauts' visors when working on the Moon's surface.
Big Muley is a 11.7 kg (26 lb) [3] breccia, consisting mainly of shocked anorthosite attached to a fragment of troctolitic "melt rock". The rock's cosmic ray exposure age was discovered to be about 1.8 million years, linking it to ejecta, or debris, from the impact that formed South Ray crater, to the south of the Apollo 16 landing site.
First Man, based on the book of the same name, tells the story of one of humanity’s greatest firsts, from the perspective of Neil Armstrong, the first human being to set foot on the Moon.
