Ultralight materials are solids with a density of less than 10 mg/cm 3, including silica aerogels, carbon nanotube aerogels, aerographite, metallic foams, polymeric foams, and metallic microlattices. The density of air is about 1.275 mg/cm 3 , which means that the air in the pores contributes significantly to the density of these materials in ...
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 ]
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.
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 design is thermally limited, hence the use of carbon as the material in Landis's concept. Low mass was the key feature of the Starwisp probe. In Landis's calculations, the mesh has a density of only 100 kg/km 2 , for a total mass of 1 kg, plus a payload of 80 grams.
A space vehicle is the combination of a spacecraft and its launch vehicle which carries it into space. The earliest space vehicles were expendable launch systems , using a single or multistage rocket to carry a relatively small spacecraft in proportion to the total vehicle size and mass. [ 1 ]
Firefighting equipment in the United States is based on lightweight materials developed for the U.S. Space Program. NASA and the National Bureau of Standards created a lightweight breathing system including face mask, frame, harness, and air bottle, using an aluminum composite material developed by NASA for use on rocket casings.
Today, this is known as "the first Marcus car" but would be better described as a cart. His second car, built and run in 1875 according to some sources, was the first gasoline-driven car and is housed at the Vienna Technical Museum. [30] [31] However, the latest research shows that it was not built until 1888/89. [32]
