Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

The simplified P2 (SP2) approximation to the transport equation is derived by a formal procedure and by a variational analysis. The variational analysis yields the SP2 equations, together with interface and Marshak-like boundary conditions. Numerical calculations show that the resulting SP2 solution is generally more accurate than the P1 solution for both integral quantities and detailed flux distributions, except near material interfaces, where the SP2 solution is discontinuous.
