Virginia Tower Norwood's Vision

Here we focus on the amazing story of Virginia Tower Norwood who invented technology that made LANDSAT's digital spectral imaging possible. In many ways, while inventing and convincing the reluctant aerospace men around her that digital imaging was the way to go, she was also continuing to be a first mover, graduating from MIT and creating a path of success for a next generation of women as scientists and engineers who would change the world.

The following excerpt from the MIT June magazine cover story shows us what went into the first LANDSAT mission -- an ongoing earth imaging and research data bank that is now going on fifty plus years. LANDSAT 9 is about to be launched and the open source archive of digital multispectral imagery is an unprecedented and unequaled font of knowledge tracking changes of Earth's systems and resources over time, a scientific treasure.

The woman who brought us the world

A half-century ago, Virginia Tower Norwood, MIT 1947, invented the first multispectral scanner to image Earth from space. Landsat 1 and its successors have been scanning the planet continuously ever since.
