Nasa's conference is slated for tomorrow in Washington DC, not at a motor inn but their own headquarters (show offs). Participants will include Mary Voytek, director, Astrobiology Program; Felisa Wolfe-Simon, NASA astrobiology research fellow, to name only a couple. The topic of "an astrobiology finding that will impact the search for evidence of extraterrestrial life" is to be discussed.
Note: The above image or an alien skull is unlikely to be discussed.
