Celebrate International Observe the Moon Night With NASA

The public is invited to participate in several of NASA’s virtual activities in celebration of International Observe the Moon Night on Saturday, October 16. This celebration provides opportunities to learn about lunar science and exploration, observe celestial bodies, and honor personal and cultural connections to the Moon.

A week of festivities began with the “Global Moon Party” on October 9, continued with social media activities, and ends with International Observe the Moon Night on October 16. Public participation will be open through October 23.

The Moon will be a waxing gibbous on October 16, offering great opportunities for viewing along the terminator – the line between night and day.

The Moon is a stepping stone to learning more about our solar system, galaxy, and universe. This year’s event shares the same date as the launch of the Lucy mission to explore the Trojan asteroids and help us better understand our solar system’s origins.

NASA has pursued lunar exploration for decades. Later this year, the Space Launch System (SLS) rocket will launch – the first in a series of missions that will land the first woman and first person of color on the Moon in the coming years with the Artemis program.
