Cool image time! NASA’s DISCOVR solar observation probe has released its first image of the Earth, taken from its station-keeping position a million miles from Earth.
This camera was originally designed for Al Gore’s proposed propaganda mission where a spacecraft would take daily pictures of the Earth to pound home his environmental agenda. Eventually NASA found a real use for the satellite’s overall structure and location, observing the Sun’s activity and give us advance warning of dangerous flares or coronal mass ejections.
They left the Earth-viewing camera on board, partly because it was built already (it would cost money to remove) and partly because daily images like this can be of some scientific value.
