Two Earth science missions, EDGE and STRIVE, were selected by NASA to study ecosystems, ice, and atmospheric composition starting in 2030, enhancing our understanding of planetary dynamics and climate modeling.
NASA selected the EDGE and STRIVE projects to fill critical observation gaps identified in the 2018 decadal survey. These missions will deploy advanced laser and infrared sensors to monitor Earth’s changing environment.
Congressional support ensured the financial viability of these initiatives by reversing earlier proposed budget cuts. This allows both programs to proceed toward a formal confirmation review scheduled for the 2027 fiscal year.
Understanding two Earth science missions
NASA selected two Earth science missions, STRIVE and EDGE, to provide global 3D mapping of ecosystems and vertically resolved atmospheric data, improving climate models and weather forecasting for future planetary exploration.
These Earth System Explorer initiatives launch in 2030 to fill critical data gaps. STRIVE focuses on atmospheric composition, while EDGE provides the first global satellite imaging laser altimeter system.
Strategic Satellite Platforms and Technology
STRIVE utilizes a Northrop Grumman LEOStar-2 bus to host infrared imaging spectrometers. Meanwhile, EDGE employs a Lanteris Space Systems platform to deploy laser sensors. These technological choices ensure high-resolution data collection for terrestrial and atmospheric monitoring across global scales.
| Mission | Lead Institution | Core Instrument |
| STRIVE | University of Washington | Infrared Imaging Spectrometer |
| EDGE | UC San Diego | Global Imaging Laser Altimeter |
- Cost Cap: $355 million per mission (excluding launch).
- Target Launch: No earlier than 2030.
- Scientific Leads: Lyatt Jaeglé (STRIVE) and Helen Amanda Fricker (EDGE).
Mission Budget and Confirmation Timeline
Both projects proceed toward a 2027 confirmation review. Each mission has a $355 million cost cap, supported by Congressional funding that reversed earlier proposed budget reductions.
Scientific importance and theories
These missions implement 2018 decadal survey recommendations for mid-cost, competitively selected ventures. They bridge the gap between small-scale satellites and large directed missions to provide vertically resolved environmental data.
Advancing Earth System Explorer Capabilities
NASA prioritized two Earth science missions to study ozone, trace gases, and glacial surface topography. By analyzing the interaction between the troposphere and mesosphere, researchers can develop more precise climate models and long-range weather forecasts that were previously unattainable with older technology.
Implications and what comes next
Research from these two Earth science missions will also inform deep-space exploration. Understanding extreme environments on Earth helps ensure astronaut safety during future Artemis lunar and Mars expeditions.
Conclusion
Advancing our knowledge through two Earth science missions ensures better protection for our home planet and future space travelers. These investments in satellite technology represent a major leap for global climate science and planetary research. Explore more on our NSN YouTube channel—join NSN Today.
