News and Events

It’s hard to believe, but it’s been one year since we celebrated Terra’s 25th Anniversary! (In case you missed it, you can get all the highlights on the Terra website).

Today, we celebrate Terra for making yet another trip around the sun (and thousands around the Earth, too!) Happy 26 years (and counting!) to Terra and her five amazing instruments (ASTER, CERES, MISR, MODIS, and MOPITT)! Thank you for another year of collecting daily morning Earth science data and inspiring the world with your endurance.

Special thanks to the entire mission team, past and present, for doing all the “behind-the-scenes” hard work to keep Terra running all these years! We appreciate you all and hope you find a way to celebrate “The Hardest Working Satellite in Earth Orbit” with us, today!

Still want more Terra Anniversary content? Check out the links above and the list below!

Check out the following animated 😅 video for more information about NASA’s 2025 Space Apps Challenge event!

Do you have some spare time this weekend (October 4 – 5, 2025*) and want to collaborate with a group to craft unique Terra animations together? Register and find a Space Apps team now using the Space Apps Connect GitHub forum (also an excellent resource during the event!) — there’s even a virtual registration option!

During the event, a team of Subject Matter Experts (SMEs) will be monitoring the GitHub forum above and answering any questions participants may have during the event. (Remember to add the Terra Animation Challenge tag to your discussion post!)

Our landing page on the NASA Space Apps website has a detailed list of resources your team can use during the event. Below, we’ve also included a Google Slideshow with examples of potential animated products created from each of Terra’s five instruments.

We hope you can join us this weekend! Good luck to all, and have fun!


*Teams should begin working on their project on Saturday, October 4. Project submission opens on Saturday, October 4 at 9:00 AM and closes on Sunday, October 5 at 11:59 PM in accordance with the time zone of your team’s Local Event. Submit a project to receive a participant certificate and to be eligible for Global Judging. No changes to the event timeline due to the government shutdown.

Registration is now open for this year’s NASA International Space Apps Challenge hackathon, to be held on October 4-5. This year, NASA is inviting innovators of all ages to Learn, Launch, Lead alongside a vibrant community of scientists, technologists, and storytellers at more than 450 Local Events worldwide.

Over the course of two days, teams will develop projects to address challenges using NASA’s open data and space-based data from Space Agency Partners. This year, participants can expect to learn skills to succeed in STEM fields, launch ideas that transform NASA’s open data into actionable tools, and lead their communities in driving technological innovation. 

For more information, check out the official Registration Toolkit, linked here, that includes all the important information, dates, and URL hyperlinks to guide you through the sign-up process!

What’s next?

  1. August 21: Challenges revealed. This year’s 19 challenges were authored by NASA subject matter experts. 
  2. September 16: Full challenge statements released, including NASA and space agency partner data sets. 
  3. October 4-5: The NASA Space Apps Challenge is held worldwide!
  4. October 6: Judging begins

Sneak Peak: Check back on August 21, when the Terra team will be providing additional information about one particular challenge involving data from our mission!

After nearly 25 years of observing Earth’s lower atmosphere, tracking harmful emissions from wildfires and industrial sources, the Canadian Measurement of Pollution in the Troposphere (MOPITT) instrument on NASA’s Terra satellite was turned off, on April 9, to conserve the satellite’s remaining power. Terra, which carries five instruments, launched in December 1999 on a six-year mission designed to study the planet’s land, ocean, atmosphere and biosphere simultaneously as the flagship mission of NASA’s Earth Observing system. Terra is a partnership between the United States, Canada and Japan. The CSA (Canadian Space Agency) contributed the MOPITT instrument to the Terra satellite.

Last month, more than 45 scientists gathered to discuss findings from MOPITT’s quarter-century record of atmospheric carbon monoxide. Its data showed a global decline in carbon monoxide emissions over two decades and could also track the atmospheric transport of the gas from fires and industry from individual regions. MOPITT is a testament to remarkable international collaboration and achievement. As it is officially decommissioned, its data record will continue to drive research for years to come.

In addition, NASA has turned power back on to Terra’s Advanced Spaceborne Thermal Emission and Reflection (ASTER) Japanese instrument. Japan’s Ministry of Economy, Trade and Industry contributed ASTER.

Another year, another cheesy Valentine’s Day card from the Terra mission!
