Design Your Own Space Mission Patch! Young space enthusiasts are invited to imagine and create their own space mission patch, just like real astronauts! Using circular templates, markers, and space-themed stickers, children will dream up their own space missions: Will they fly to Mars? Visit a distant galaxy? Search for alien life? Each child will choose a mission goal, name their spacecraft, and design a patch that tells the story of their adventure. As they draw, children will hear inspiring stories about real-life women astronauts, encouraging early interest in space careers and diverse role models in STEM. Finished patches will be displayed during the event to celebrate their creativity and curiosity. Recommended for children in grades K-5. This special activity is part of Massachusetts STEM Week 2025 and is organized by The Space Consortium, the local space education and outreach nonprofit behind Massachusetts Space Week (April 20-26 2026).

This presentation incorporates 4-5 live birds of prey that all native to New England. The program is designed to explain predation, the birds' place at the top of the food web, their different hunting adaptations and their status in a rapidly changing world. Because many birds of prey are declining in number, this presentation also features one or more of the endangered raptors that Wingmasters cares for, and explains why these species face an uncertain future. Recommended for children ages 6 and up and their caregivers. This program can accommodate 75 people. Tickets are available on a first come, first served basis on the day of the program. The entire party must be present to receive a ticket. This program starts promptly. Unclaimed seats will be offered to someone waiting. We appreciate your patience and understanding. Funding for Summer Reading has been generously provided by the City of Cambridge, Cambridge Public Library Foundation, Friends of the Cambridge Public Library and the Massachusetts Board of Library Commissioners.

The 1% for Public Art component of the Kendall Square / Main Street project was the creation of artist designed bike racks. Six artists were chosen by an art jury to participate in this project. Each of the selected artists created three or four designs that were represented in a gallery exhibit by drawings, models and artists’ statements. The artists had to balance his or her artistic mission with factors of successful functionality, ease of maintenance, compliance with the Americans with Disabilities Act, and economy of cost. During the exhibit and at the April 10, 2012 Kendall Square Public meeting, members of the public were asked to comment and vote on the different designs. Approximately 650 votes were received. On June 4, 2012 the selection committee met and selected 5 bike racks to be used in Kendall Square. The selection committee included city staff, a member of the Bicycle Committee and two members of the Kendall Square Advisory Committee. In making their selection, the committee considered the public input (voting and comments), functionality of the racks, appropriateness for Kendall Square, and artistic interest. Since the initial installation, some of the artist designed bike racks have been moved to new locations throughout the City.
