The King learned about Project Nova at the observatory on Cooper’s Island, which will oversee the installation of a network of telescopes across five sites to help track material in space, such as old satellites and rocket stages.
He then opened a new Great Bay Coast Guard Station in St David’s, where he awarded operational medals to members of the Royal Bermuda Regiment and viewed new technology used to protect the island’s waters and marine environment.
Later at LF Wade International Airport, a small group of dignitaries including Premier David Burt gathered as the King drew the visit to a close.
The monarch walked a short stretch of red carpet and spoke to leading figures including the commissioner of police Darrin Simons and leader of the opposition Ben Smith.
Shortly before boarding the plane, the King posed for a photo with assembled officials including police and security personnel.
It followed the first full day of his visit on Friday, which included a boat trip with the coastguard, a cake-cutting event and a visit to the National Museum of Bermuda.
He also viewed artefacts from the transatlantic slave trade and visited a conservation initiative.
