Keith's note: A month ago I posted news that NASA Advisory Council chair Steve Squyres had sent an email to the NAC and to NASA - resigning as chair of the NAC. In the month that followed this posting NASA has said nothing about the status of the NAC. If you go to the NAC home page at NASA nothing has changed in terms of NAC membership (including people whose terms have expired). Squyres is also listed here as NAC chair. Although the NAC discussed having a meeting in Cleveland in July no future meeting dates are listed here.
