The rocket blasted off at 11:06 a.m. Beijing Time from waters off the coast of Yangjiang, a city in south China's Guangdong Province. The Taiyuan Satellite Launch Center conducted the offshore launch.
It was the third flight mission to use an SD-3 rocket, said the center.
The SD-3 is a solid-fueled carrier rocket that was developed by the China Academy of Launch Vehicle Technology and specifically designed for the commercial space market. It is capable of both land and sea lift-offs.
Liu Wei, deputy chief designer of the SD-3 rocket, said that the launch point for this mission was adjusted to a location closer to shore, resulting in reduced wind and wave conditions compared to earlier missions.
The rocket's two previous flights used 63 sensors per launch. As sufficient data had already been acquired, this launch used just 31 sensors, lowering costs further, Liu added.
Liu said the Nexsat-1 satellite, one of the nine satellites aboard the rocket, was designed for international clients.
In a historic achievement for Egypt’s national space programme, the Egyptian Space Agency (EgSA) has launched its experimental satellite, Nexsat-1.
Nexsat-1, primarily designed for remote sensing, represents a collaborative effort between Egypt and Germany’s Berlin Space Technologies (BST). Throughout the satellite’s developmental phases, EgSA played a pivotal role, focusing on critical operating software and systems.
Dr Sherif Sedky, CEO of EgSA, highlighted the significance of Nexsat-1 in advancing micro-satellite technology localisation in Egypt and Africa.
Beyond project oversight, EgSA actively contributed to designing satellite missions, outlining technical descriptions for various subsystems, and establishing collaborative frameworks with the German team.
Additionally, they developed a complete Egyptian version of the satellite’s software and managed the intricate assembly, integration, and testing (AIT) processes, showcasing EgSA’s end-to-end capabilities in satellite development.
EgSA also coordinated the entire launch process and established a control station in Egypt for seamless communication with the satellite and retrieval of relevant data.
Weighing 67 kg, Nexsat-1 is categorised as a microsatellite and features a space payload for electro-optical imaging, offering a multispectral resolution of 5.7 meters for high-detail imagery. ■
