– July 19, the Cassini mission captured several shots of the Earth from its vantage point, within the orbit of Saturn. Check out the other image, and our article here: http://on.fb.me/11aupgB
At a distance of about 1.5 billion km (900 million miles) from Earth, our home planet appears as just a pale blue dot.
This image is one ‘footprint’ in a mosaic of 33 images that capture the whole ring system of Saturn, including the gas giant itself. Each footprint was imaged with several spectral filters, resulting in a total of 323 images. However, this is the only wide-angle shot which contains our own planet.
This ‘natural colour’ view was created by combining red, green and blue spectral filters.
Cassini Project Scientist, Linda Spiker commented, “Cassini’s picture reminds us how tiny our home planet is in the vastness of space, and also testifies to the ingenuity of the citizens of this tiny planet to send a robotic spacecraft so far away from home to study Saturn and take a look-back photo of Earth”. –
