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 activation energy for graphite oxidation was obtained from the change in the “stable length” of channel with temperature. The maximum temperature at which thermal equilibrium (between the heat generated by graphite oxidation and the heat removed by the air stream) will occur in a channel can be predicted from the heat transfer coefficient, the activation energy, and a single value of the graphite reactivity at any temperature. Above this maximum temperature, the total length of channel is thermally unstable. An equation is given expressing the length of channel that can be cooled as a function of temperature, flow rate, diameter, and reactivity.
