U.S. Embassy in Dublin Tweets: #AskCharlie A Question

Keith’s note: The U.S. Embassy Dublin @usembassydublin recently tweeted “Some weird and wonderful #AskCharlie questions still coming in! Its your opportunity to quiz the head of NASA! pic.twitter.com/n45uZxox” Here is what people have asked thus far.
So … I guess Charlie Bolden is going to be visiting Ireland, right? Otherwise, why do this? What is curious is why NASA PAO has said nothing about this official government contest such that people can participate. Larger image.
Keith’s update: NASA PAO says that Bolden is “in the UK now for Farnborough and is going [to Ireland] tomorrow.”
