what are you talking about
NASA announced the selection of two new Earth observation missions, STRIVE and EDGE, under the Earth System Explorer Program. The satellite is scheduled to be launched by 2030. Its main purpose is to study changes in Earth’s atmosphere, ice sheets, and ecosystems. climate change.
STRIVE and EDGE focus on different aspects of climate
STRIVE (Stratospheric Tropospheric Response Using Infrared Vertical Resolved Optical Explorer) measures temperature, ozone, aerosols, and trace gases from the upper troposphere to the mesosphere. EDGE (Earth Dynamics Geodetic Explorer), on the other hand, will focus on mapping the 3D structure of forests and measuring the topography of glaciers, ice sheets, and sea ice. Both missions are part of a competitive program for small, cost-effective Earth science satellites to address high-priority climate issues.
Why do we need a new mission?
Due to major changes in climate, glaciers, and weather patterns, scientists decided to start these two projects. Existing satellites provide valuable data, but scientists say higher resolution and better vertical measurements are needed to improve predictions and improve climate models. To this end, it is important to understand how the upper atmosphere interacts with surface changes.
How do satellites collect and transmit data?
Like other NASA Earth observation missions, STRIVE and EDGE orbit the Earth and transmit data to ground stations. Their equipment uses advanced sensors and infrared measurements to collect precise measurements. Mission control teams and a global tracking network continuously monitor its location, status, and data flow. Scientists around the world then analyze the incoming information to update climate models and environmental assessments.
technological progress
How will new technology improve data collection?
STRIVE uses powerful infrared sensors to take more than 400,000 daily snapshots of atmospheric temperature, ozone, aerosols, and trace gases. EDGE, on the other hand, emits 150,000 laser pulses per second to create detailed 3D maps of forests and ice. These technological advances are expected to provide greater atmospheric detail and broader imaging capabilities of polar regions and forests than any previous mission.
