We have begun to write the PDR.
The main engine selected was the Rocketdyne XLR-132. We found out Thursday that the program for producing the XLR-132 has ceased. One could be produced, but it could take up to two years to produce. The cost is unknown at this time. Therefore, we are evaluating the Transtar engine as well as the XLR-132. The point of main engine jettison should be calculated by the end of the day.
