The launch came after three failed attempts.
The launch was expected to first take place on April 11 but was pushed to, April 12 then April 14, and later April 15 when it happened at Vandenberg Air Force Base. Bad weather was the cause of the delays.
The country was all set to witness the historic launch which was streamed live from the University of Nairobi.
It happened Saturday at about 9.45 am.
Officials have termed the launch as an important milestone adding that it would contribute significantly to the country’s “budding space economy”.
The observation satellite is fully designed and developed by Kenyan engineers and will be used to provide data on agriculture and food security, among other areas, the Kenya Space Agency said.
Testing and manufacturing of the parts were done in collaboration with a Bulgarian aerospace manufacturer, it added.
The satellite launch will add to a push by African nations for scientific innovation and the development of space programs.
Egypt was the first African country to send a satellite into space in 1998.
In 2018, Kenya launched its first experimental nano-satellite from the International Space Station.
