Mr Bridenstine work will kick off this year, starting with a number of commercial delivery missions to the Moon with “new landers, robots and eventually humans by 2028”.
He said: “As we approach the 50th anniversary of Apollo 11 this July, we are moving forward to the Moon and on to Mars, and we want the world to come with us.
“NASA is everywhere, and we are impacting people’s lives across the globe.
“As we celebrate the past, let’s inspire our friends and family for the future that we are building.”
