The centerpiece of outreach for LPL in 2019 was the 50th anniversary of the Apollo 11 Moon landing. The public outreach and education events maintained a focus on local contributions to the Apollo program, with an emphasis on the contributions by LPL, which was established in 1960 in large part because Gerard Kuiper wanted to study the Moon. When President John Kennedy made sending humans to the Moon within the decade a national priority the next year, the fledgling LPL was perfectly situated.

For the 50th anniversary of the Apollo 11 landing, LPL, the University of Arizona, and venues across the city of Tucson celebrated the anniversary and the foundational contributions made by scientists and talented engineers and craftspeople not only from LPL but also from other local organizations. In recognition of the local contributions, by Proclamation of Mayor Jonathan Rothschild, July 2019 was declared Tucson Moon Month. Venues and events across Tucson joined the fun by sponsoring Moon related exhibits, movies, and lectures as part of UArizona Apollo 11 50th anniversary moonfest events. The 2019 calendar was filled with a variety of activities, including LPL's annual Summer Science Saturday, held this year on July 20 and attended by 800 guests. Also on July 20, Flandrau Science Center and Planetarium provided special Apollo programming and the UA Special Collections Library debuted a wonderfully curated Moon exhibit, which showcased materials from the Ewen Whitaker collection, in addition to other exhibits and activities related to lunar science. UANews produced a comprehensive suite of articles detailing the LPL-UArizona-Apollo connections.
