You may recall a couple of weeks ago reports that the Obama Administration had narrowed down its list of candidates for NASA administrator to several, perhaps four, names. This afternoon the Orlando Sentinel reported who its sources say are those four. Three of the names have already come up in previous weeks: retired generals Charles Bolden, Scott Gration, and Lester Lyles. The fourth, those, is a new name to this race but a familiar name for many: Steve Isakowitz, the current CFO of the Energy Department and a former NASA and OMB official. (Some will also recognize him as the founding author of the International Reference Guide to Space Launch Systems, a popular reference guide to launch vehicles whose fourth edition was published in 2004 with Isakowitz as one of three co-authors.) The Sentinel adds that Isakowitz is the “frontrunner”, but doesn’t indicate when the race for that job will end: after all, a number of other frontrunners, including the three other names on the list, were all considered frontrunners at some point in the past but haven’t (yet) gotten the job.
