Advances in NASA Imaging Changed How World Sees Mars

Sixty years ago, NASA’s Mariner 4 captured groundbreaking views of the Red Planet, leading to a steady stream of advances in the cameras used to study other worlds.

Here is another section of the Mariner 4 image sequence with pictures located on a modern map. The previous 6 images were taken with high sun and in an area of fairly bland landscapes (at this resolution), but here we get recognizable craters. Some are named after explorers (before they became unfashionable). Mariner itself gets a crater named after it.

I mis-spoke there - we don't see a new map right now, but new things. This map, with the old Air Force map as a base, shows the locations of the Mariner 4 images taken in 1965. We take this for granted today but the idea that you could build a machine and send it to Mars, and get pictures of its surface back was unbelievably audacious at the time. There were a few extra frames but they crossed the terminator and showed nothing. How did I know where to put those images? #maps #Mars #Mariner4

The first digital image from space was a color-by-number... with some assembly required.

"A real-time data translator machine converted Mariner 4 digital image data into numbers printed on strips of paper. The team colored in the strips by hand with pastels, making this both a work of art and the first digital image from space." - NASA/JPL-Caltech (https://science.nasa.gov/mission/mariner-4/)

Mariner 4 - NASA Science

What was Mariner 4? The Mariner 4 mission, the second of two Mars flyby attempts launched in 1964 by NASA, was one of the great early successes of the agency, and indeed the Space Age, returning the very first photos of another planet from deep space.
