NASA 50th Anniversary Probes

Probes

Gone are the days of grainy black and white images, transmitted for days from planetary probes back to Earth. Technology has evolved exponentially in the five decades since NASA was born. Just 30 years ago banks of computers filled rooms, processing mere kilobits of data for a handful of images. Today's probes return high definition, 3-dimensional colour images that show not just stratagraphic surface features, but incredible detail within them. With these images comes a greater understanding of the Solar System around us and our place within it.
