DOVER – The city is looking to purchase a solar system exhibit that could transform a section of the Community Trail into a STEM experience for students and community members alike. Visitors of the trail would walk past signs engraved with information on a scaled model of the solar system, starting at the sun and ending at Pluto. Chris Parker, assistant city manager and planning director, spoke with the city School Board at Monday's meeting, explaining the city and school district have been evaluating possibly adding a Voyage Mark II Scale Model Solar System Exhibition to Dover, as part of the Voyage National Program.
