STELLA Website Migration Announcement

We’re excited to announce that the STELLA (Science and Technology Education for Land/Life Assessment) website is moving to its new home!

New URL: https://science.gsfc.nasa.gov/stella

This migration reflects STELLA’s exciting evolution beyond its Landsat origins. While we continue to celebrate the remarkable achievements of the Landsat program—the longest-running Earth observation satellite program that has provided an unparalleled 50+ year record of our changing planet—STELLA has grown into a truly multi-disciplinary platform.

The STELLA (Science and Technology Education for Land/Life Assessment) project uses spectrometers that can be built with low-cost components and 3D printed housings to introduce NASA Earth observation technologies and provide authentic hands-on learning experiences for remote sensing education. STELLA instruments help engage students in the quantitative aspects of satellite data, provide insight into the scientific process, and encourage analytical thinking.

Building STELLA instruments provides the opportunity to learn engineering design concepts and gain an appreciation for the instrument development process. Above: NASA high school intern, Sabrina Pillai, shows a younger student how to troubleshoot a STELLA-1.1 device using a digital multimeter.
