Ultralight materials are solids with a density of less than 10 mg/cm 3. Ultralight material is defined by its cellular arrangement and its stiffness and strength that make up its solid constituent. They include silica aerogels, carbon nanotube aerogels, aero graphite, metallic foams, polymeric foams, and metallic micro lattices. [1]
A metallic microlattice is a synthetic porous metallic material consisting of an ultra-light metal foam. With a density as low as 0.99 mg/cm 3 (0.00561 lb/ft 3 ), it is one of the lightest structural materials known to science. [ 1 ]
An aerogel material can range from 50% to 99.98% air by volume, but in practice most aerogels exhibit somewhere between 90 and 99.8% porosity. [12] Aerogels have a porous solid network that contains air pockets, with the air pockets taking up the majority of space within the material. [13]
Stuff Matters: Exploring the Marvelous Materials That Shape Our Man-Made World is a 2014 non-fiction book by the British materials scientist Mark Miodownik. The book explores many of the common materials people encounter during their daily lives and seeks to explain the science behind them in an accessible manner.
The General Motors Ultralite was a 1992 low emission vehicle concept car intended to demonstrate the benefits of advanced materials and low fuel consumption.. It was rated at 88 miles per US gallon (2.7 L/100 km; 106 mpg ‑imp) by the EPA, [1] but could achieve 100 miles per US gallon (2.4 L/100 km; 120 mpg ‑imp) at a steady state cruising speed of 50 mph.

America’s first Black astronaut candidate finally rocketed into space 60 years later, flying with Jeff Bezos’ rocket company on Sunday. Ed Dwight was an Air Force pilot when President John F ...
The car and rocket are products of Tesla and SpaceX, respectively, both companies headed by Elon Musk. [5] The 2010 Roadster is personally owned by and previously used by Musk for commuting to work. [2] It is the first production car launched into space.
Russia's Soyuz rocket blasted off from its Plesetsk launch site some 500 miles (805 km) north of Moscow on May 16, deploying in low-Earth orbit at least nine satellites including COSMOS 2576, a ...
