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.

Low-frequency turbulence and the resultant cross-field plasma transport in mirror-based systems are studied by means of direct computer simulations of nonlinear plasma dynamics. Under the low-beta assumption the nonlinear dynamics are simulated in a frame of adiabatically reduced one-fluid MHD model. Simulations of self-consistent plasma evolutions have shown formation of large-scale flute-like stochastic vortex structures, which have broad-band frequency and wave-number spectra and are similar to the intermittent vortex-like structures observed in GAMMA 10 experiments. Simulations were performed both for the conventional tandem mirror configuration and for axisymmetric non-paraxial configuration with divertor-like separatrix. Various regimes of plasma confinement with sheared plasma rotation have been modeled and analyzed.
