Dreier used official NASA budget submissions to Congress and internal documentation describing appropriations for facilities and overhead expenses during FY 1961 to 1973 as the basis of his reconstruction of Apollo costs, then adjusted them for inflation using two inflation indices tailored specifically for aerospace projects. Exploring the costs involved in beating Soviet spacecraft to

As sunlight passes through Earth’s atmosphere, molecules of nitrogen and oxygen scatter shorter blue wavelengths more strongly than other colors – an effect known as Rayleigh scattering. Longer wavelengths like yellow, red and orange pass unimpeded through the atmosphere – so why is the sky light blue? Unfortunately, the answer lies somewhere within. The Sun’s

At launch sites, the physical structures that garner the most interest are assembly buildings. Cape Canaveral’s VAB, for instance, was specifically designed to assemble Saturn V rockets vertically while they traveled down an overhead gantry track toward their pads. Aerospace is focused on designing architectures with greater resilience and the capacity to reassemble quickly, necessitating

Mercury oxide decomposes when exposed to heat, producing elemental mercury and liquid metal mercury in an orderly and balanced chemical reaction that was conducted by Antoine Lavoisier who studied chemical reactions as well as classifying substances into elements and compounds. Mercury(II) sulfide is a dense black or red crystalline solid used to produce zinc-mercuric oxide

Light from the Sun The Sun is the engine that drives our solar system and produces enormous amounts of energy that radiates outward from its core in various forms – visible light, heat, x-rays and radio waves being among them. Since 4.5 billion years ago it has been burning with increasing intensity, and will likely
