Associated space launch
Okean-O was a joint Ukrainian and Russian remote sensing satellite program designed as a follow on to the Okean-O1 series. It was designed to gather remote sensing data crucial for research of natural resources of the Earth and world oceans. The mission also included ecological monitoring and management of externalities (weather forecast, hazards prevention).
SL-16 DEB was lifted into orbit during the mission ‘Zenit-2 | Okean-O’, on board a Zenit-2 space rocket.
The launch took place on July 17, 1999, 5:38 a.m. from 45/1.
