Douglas Gerald Hurley (born October 21, 1966, 53) is an American engineer, former Marine Corps pilot, and current NASA astronaut. He piloted Space Shuttle missions STS-127 (July 2009) and STS-135 (July 2011), the final flight of the Space Shuttle program.
He launched into space for the third time as Commander of Crew Dragon Demo-2, the first crewed spaceflight from American soil since STS-135.
Hurley and Behnken will work with the crew of Expedition 63 for 30 to 90 days. They should return no later than 28 August 2020.
Docking and undocking operation will be autonomously controlled by the Crew Dragon spacecraft, but monitored by the flight crew in case manual intervention becomes necessary.

Isn’t it like a pop star? Once they reach the pinnacle of fame they can now just go by a single name, like Elvis, or JLo or someone.
The way astronauts are always referred to by their first names and even nicknames. This despite most being military officers (both Bob and Doug are Colonels). I think Bob also has a PhD.
I guess once you become an astronaut there is really not much need of an ego.
Is this what you were thinking…
