Observe Like Artemis!

Participate in the #ObserveLikeArtemis Challenge |
22 April to 22 May

Were you inspired by the Artemis II mission? From today to the 22nd of May, show us what Earth means to you by taking GLOBE observations of your favorite features of Earth—whether it’s a cloud, a tree, a local waterway, or soil from a nearby forest! In May, we’ll share how many observations were submitted for each sphere.

Help GLOBE Reach 2 Million Satellite Matches by Next April

1.6 Million Matches and Counting!

When you submit Cloud and Land Cover observations via the GLOBE Observer app, if they match with satellite data, they will count toward our goal of 2 million matches! You’ll know you got a match when you receive an email from NASA with satellite data that aligns with the data you submitted, allowing you to compare your ground-level view with what satellites observe above. 

Rediscover the GLOBE Community Poem– in Print!

GLOBE is collaborating with SciStarter to encourage Acts of Science this month. If you take a GLOBE Clouds, Land Cover, Mosquito Habitat, or Trees observation during April, it will count toward SciStarter's goal to reach 2.50 Million Acts of Science.
