Keith's note: According to her Wikipedia page Lesa Roe "is currently serving as the Acting Deputy Administrator of NASA. Roe is also the Deputy Associate Administrator of NASA, being in role since May 2014.". I cannot find any announcement from NASA or the White House that she was appointed to the position of Acting NASA Deputy Administrator.
The Wikipedia page was last revised to add Roe's new position on 1 February 2017 by someone named "Hosgeorges" from the UK. On 22 February 2017 someone named دارين added a picture of Lesa Roe. Prior to that Roe's Wikipedia page was last changed on 8 May 2016. This senior leadership page on NASA.gov only mentions Robert Lightfoot as Acting NASA Administrator. But this page at NASA.gov (last changed on 10 February 2017) says "Deputy Administrator: Lesa Roe (acting)". So Hosgeorges in the UK knew about this NASA management change nearly a month ago - and NASA quietly added it to its website 2 weeks ago - but no one thought to put a memo out for the rest if us?
But wait: there's more: This page links to a NASA Advisory Council page shows a group portrait of the NAC with former NASA Administrator Charlie Bolden and refers to "Mr. Kenneth Bowersox (NAC Interim Chair)". Yet this page mentions the NAC and says "Chair: General Lester L. Lyles (USAF, Ret.)"
On 20 January 2017 Robert Lightfoot sent out a memo "Message from the Acting Administrator of NASA" which said "As the transition progresses, we have some initial assignments from the new administration. Erik Noble has been named White House Senior Advisor at NASA. Greg Autry, who was with the Agency Review Team, has been named White House Liaison."
According to this current NASA Organization Structure page last updated 10 February 2017 Erik Noble is now "Chief of Staff (acting)". According to multiple sources Greg Autry told people that he would be leaving his White House Liaison position at NASA effective 17 March 2017. But he left on 23 February instead. Oddly, the page was last updated on 10 February 2017 yet made no mention of Autry despite the importance of his position at the time.
Things are starting to get a little strange when NASA makes significant agency appointments like this and does not tell anyone else - except Hosgeorges and دارين that is.
