Join Madison Square Park Conservancy for a celebration inspired by our Moon Tree, an American Sweetgum sapling grown from seeds that traveled around the Moon aboard NASA’s Artemis I mission. 

Commemorating the 57th anniversary of the first lunar space launch, this free, all-ages event will feature safe solar viewing, hands-on science experiments, scavenger hunts, an interactive Moon Tree art gallery, guided tours of our Celestial Gardens, and “Ask a Scientist” sessions with working experts. And don’t miss the unveiling of a specially commissioned poem by New York State Poet Laureate, Kimiko Hahn, in honor of our Moon Tree!

The day’s main celebration will take place from 4:00 PM to 8:00 PM, including a special children’s presentation at 4:30 PM and closing remarks at 7:15 PM.
