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 solution of the neutron slowing down equation in an infinite, homogeneous moderator (with nuclei of mass M) has been obtained by means of direct summation of transition probabilities between the initial and final energy states. It has been possible to obtain an exact formula for the distribution of neutrons in lethargy space after N collisions with moderator nuclei. The asymptotic expansion of the results for large and for very large N is in agreement with the Dancoff's formulas. The accuracy of the asymptotic expansion has been estimated.
