Infrastructure Atomic Rockets

As the delta V for a mission goes up, the amount of propellant required goes up exponentially (or looking at it another way the amount of payload shrinks exponentially).Large amounts of propellant are expensive, but the higher the mass ratio the higher the likelihood that the spacecraft will not be resuable.

Radium

Radium

Radium is a chemical element with symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals.Pure radium is silvery white, but it readily reacts with nitrogen (rather than oxygen) on exposure to air, forming a black surface layer of radium nitride (Ra 3 N 2).All isotopes of radium are highly radioactive, with the most

Nonmetal

Nonmetal

In chemistry, a nonmetal (or non metal) is a chemical element that mostly lacks metallic attributes. Physically, nonmetals tend to have relatively low melting and boiling points, and densities, are mostly brittle if solid, and are usually poor conductors of heat and electricity; chemically, they tend to have relatively high ionization energy, electron affinity, and electronegativity values
