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.

A Godunov scheme is proposed for the simulation of impact problems and detonations where nonstationary fronts and interfaces are tracked as boundaries of subregions that move in time. In each subregion and at each time step, a new grid is created by the use of boundary-fitted coordinates. The numerical method is based on a finite-volume approach in the space-time domain, and the fluxes are calculated using the solution of Riemann problems. Numerical results are shown for several impact and detonation problems, showing the efficiency of this approach.
