participatory space exploration. These projects, developed as part of MIT's Space Exploration Initiative, range from nanoscale imaging of microbes to responsive, sensor-mediated living environments. They show the usefulness of a seahorse tail for humans in microgravity, document the promise of shape-memory alloys for CubeSat in-orbit maneuvering, and introduce TESSERAE (Tessellated Electromagnetic Space Structures for the Exploration of Reconfigurable, Adaptive Environments), self-assembling space architecture. Some are ongoing, real-world systems: an art payload sent to the International Space Station via Space X CRS-20, for example, and a crowdsourced interplanetary cookbook. More than forty large- format, coffee table book-quality, full-color photographs make our future in space seem palpable. Short explanatory texts by Ariel Ekblaw, astronaut Cady Coleman, and others accompany the images.
