2 Million Satellite Matches by April 2027

See how your view from the ground compares to the satellite view from above! When you submit Cloud and Land Cover observations via the GLOBE Observer app and they align with satellite flyover timing, you receive an email from NASA with satellite data that correspond with the data you submitted.

To date, NASA has made 1,721,495 matches! Help us reach our goal of 2 million satellite matches by making an observation today. 278,504 more to go...

GLOBE Contributes to Acts of Science Challenge

SciStarter Challenge Surpasses 4 Million Acts of Science

For Citizen Science Month in April, SciStarter, an online citizen science hub, invited everyone, everywhere to join the 2.50 Million Acts of Science challenge. During the month, more than 400,000 participants reported more than 4.7+ million Acts of Science — far exceeding the original goal. Read about GLOBE's Acts of Science contributions.

GLOBE Annual Meeting

GLOBE Learning Sessions Conclude

Since the 2025 GLOBE Annual Meeting last July, the GLOBE Implementation Office (GIO) has offered a series of GLOBE Learning Sessions, featuring topics like phenology, blowing snow, GLOBE alumni engagement, NASA’s visualization studio, and highlights of the work of community members.

The series concluded with the April Learning Session on GLOBE Phenology: Designing Collaborative, Impactful Research Campaigns.

Browse recordings of all past Learning Sessions.

2026 GLOBE Annual Meeting

Stay tuned for details about the 2026 GLOBE Annual Meeting! The event will be virtual and is tentatively planned for October 2026.

GLOBE Cup Challenge

Observations of Soccer (Football) Fields | 11 June to 19 July

Whether you play soccer (football), cheer from the sidelines, coach a team, or simply live near a field, you can help investigate the environment where soccer (football) is played in your community. Is the field surrounded by trees, buildings, dirt, or pavement? Is it grass, artificial turf, or another surface? How do temperatures compare from one day to the next — and how does your local field compare to fields around the world?

During the World Cup, from 11 June to 19 July, participate in the GLOBE Cup Challenge by joining the GLOBE Team in your region and taking observations of air temperature, surface temperature, and/or land cover at your local soccer (football) field, park, schoolyard, or anywhere people play. 

Let’s see which GLOBE region is the biggest soccer (football) fan! We’ll track participation around the world and highlight observations and soccer (football) fields from different GLOBE regions. Learn more.

Mission Mosquito

Are You Seeing Mosquitoes?

As the weather warms in parts of the world, female mosquitoes are beginning to lay eggs. This is a great time to make mosquito observations. Find resources and webinar recordings.

Observe Like Artemis Challenge

The Observations Are In!

From 22 April through 22 May, the GLOBE community collected data across regions as part of the Observe Like Artemis Challenge, taking inspiration from the astronauts who observed the moon (and Earth!) during the Artemis II mission. Together, the community submitted over 16,000 observations. Learn more about the data collected and view a few of the many photo observations submitted!

Trees Around the GLOBE

Upcoming Webinar

• Best Practices and Research Work from the STEM Enhancement in Earth Science (SEES) Summer Intern Program, Supported by NASA: An Intimate Look into a Special Issue of the Journal of Earth Observation and Geospatial Applications | 9 June at 1 pm ET (17:00 UTC; 18:00 CET) Join us to hear Peder Nelson and SEES students present several research projects that are part of a special issue of the Journal of Earth Observation and Geospatial Applications.

Webinar Recording

• The NASA Moon Trees Legacy: Building Generations of Tree Height and Land Cover Observations and Stewardship from Apollo to Artemis | Take a trip back to the 1970s to explore the original NASA Moon Trees and Apollo 14 Missions. Then move to 2022 and the Artemis I Mission and learn about the continued legacy of the amazing seeds that flew from Earth to around the moon and back.

GLOBE Observer Connects

Upcoming Webinar

Kicking Off the GLOBE Cup Challenge

11 June at 12 pm ET (16:00 UTC)

Land cover vs. temperature: the GLOBE Cup Challenge is on! Join us for a conversation with scientists (and soccer fans) Dr. Eric Brown de Colstoun from NASA Goddard Space Flight Center and Dr. Kevin Czajkowski from the University of Toledo. They will set the stage for the GLOBE Cup Challenge by exploring the science of how the type of ground where people play soccer (football) influences the surrounding temperature. Learn more and register.

Webinar Recording

Observe Like Artemis Webinar Recording

What did the Artemis II astronauts look for as they journeyed around the Moon — and why does it matter? In the May GLOBE Observer Connect session, members of the Artemis II Lunar Science Team shared the science behind the mission, the key observations astronauts made, and how those discoveries could help answer fundamental questions about the Moon, Earth, and our solar system. Watch the recording for a behind-the-scenes look at the mission's science objectives and advice for making scientific observations!
