China Demonstrates Dual Space Prowess with Smart Dragon 3 and Long March 7A Missions

Edited by: Tetiana Martynovska 17

On September 16, 2025, China showcased its advancing space capabilities through two significant launches: the Smart Dragon 3 and the Long March 7A. These missions underscore China's commitment to expanding its presence in space for diverse applications, ranging from environmental monitoring to advanced satellite deployment.

The Smart Dragon 3, a solid-fueled rocket developed by the China Academy of Launch Vehicle Technology, embarked on its seventh maritime flight from a platform near Rizhao in Shandong province at 3:48 AM local time. This 31-meter tall, 140-ton rocket is engineered to deliver payloads of up to 1.5 tons to a 500 km sun-synchronous orbit. Its payload for this mission comprised 11 multifunction satellites from Geespace, designed to bolster marine industries, transportation management, IoT experiments, and environmental monitoring. The Smart Dragon 3's capacity for sea-based launches offers enhanced flexibility and reduces risks to populated areas, aligning with China's strategy to diversify its launch infrastructure.

Just over six hours later, at 10:00 AM local time, a Long March 7A rocket ascended from the Wenchang Space Launch Center in Hainan province. This launch successfully placed the Yaogan 45 remote-sensing satellite into orbit. The Yaogan 45, developed by the Shanghai Academy of Spaceflight Technology, is intended for scientific experiments, land surveys, agricultural monitoring, and disaster prevention efforts. The Long March 7A rocket, a variant of the Long March 7, is capable of carrying a 7-ton payload into a geosynchronous transfer orbit and has been a key component in China's efforts to deploy satellites to higher orbits.

The Yaogan series is noted for its remote sensing capabilities, with some satellites in higher orbits to expand coverage and observation time, potentially for strategic surveillance. These dual launches highlight China's growing proficiency in both commercial satellite deployment and advanced remote sensing technology. The Smart Dragon 3's maritime launch capability is a testament to China's strategic expansion into flexible and resilient launch operations. Simultaneously, the Long March 7A's mission with the Yaogan 45 satellite demonstrates advancements in satellite technology aimed at enhancing Earth observation and data collection for various sectors, including environmental monitoring and disaster management.

China's commitment to these space initiatives positions it as a significant player in the global space economy, driving innovation across multiple industries.
