July 16 | 12 – 8 PM | Throughout park

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!

Full schedule to be announced. Register to receive event updates and be the first to see the complete schedule when it’s released. Free and open to all.

This program is supported by Simons Foundation International and administered by Simons Foundation’s Science, Society & Culture division.

The Madison Square Park Moon Tree is part of NASA’s Artemis Moon Tree initiative, developed in partnership with the USDA Forest Service. The summer celestial poetry installation is presented in partnership with the Poetry Society of America.
