Boston, the birthplace of John F. Kennedy, was chosen to host the second annual prize ceremony because of the late president’s 1962 “moonshot” speech, setting the challenge for Americans to reach the moon by the end of the 1960s.

It inspired the prince and his partners to set a similar goal for finding solutions to climate change and other environmental problems by 2030.

During their first day in Boston, William and Kate attended a Boston Celtics game, sitting courtside with Celtics co-owner Wyc Grousbeck and his wife, Emilia Fazzalari, co-owner Steve Pagliuca and his wife, Judy, Celtics great and Hall of Famer Thomas “Satch” Sanders, Massachusetts Gov.-elect Maura Healy and Boston Mayor Michelle Wu.

During the game, the Heroes Among Us award was presented to Ollie Perraul, a 15-year-old climate activist from Easthampton, Massachusetts. The royals were seen talking with Perraul after the award presentation.

William and Kate received mixed reactions when they were shown on the Jumbotron as some fans applauded and cheered, while others appeared to boo the royals. However, the pair appeared to be enjoying themselves, and William was spotted clapping and cheering the players on throughout the game.

The royals’ trip comes amid some controversy surrounding an honorary member of the Buckingham Palace household. Lady Susan Hussey, William’s godmother, was reportedly forced to step down from her position after she was accused of repeatedly asking a Black woman born in Britain where she was “really” from.

Their U.S. visit also highlights the rift with William’s brother Prince Harry and Meghan Markle, who moved to California in 2020. William and Kate reportedly have no plans to see Harry and Meghan while they’re in the U.S.
