Nasa's giant Moon rocket has returned to its launch pad for a second time, ahead of a mission to send astronauts around the Moon – something not attempted in more than 50 years.

Nasa has, for the second time this year, rolled its colossal moon rocket from its hangar to the launchpad, hoping to send four astronauts on a lunar fly-around mission next month.

Dr. Addie Dove, a planetary scientist at the University of Central Florida, joins Good Day Orlando to talk about the importance of the mission.

NASA is revising its moon-landing plans, reducing Boeing Co.’s role while elevating SpaceX’s Starship rocket to do the job of propelling astronauts to lunar orbit, people familiar with the matter said.
