Planet Labs (now more commonly called simply 'Planet') launch of the Planetscope DOVEs was organised around the main idea to image Earth every day.
Planet designed an ultra-compact, inexpensive cubesat which could be manufactured in bulk.
135+ DOVES from Planetscope have been launched into a single orbit plane, circling Earth every 90 minutes.
