High-resolution images from the latest Jielong-3/SD-3 sea launch, which successfully inserted into orbit a total of nine satellites: DRO-L; Zhixing 2A; Oriental Smart Eye Gaofen 01; Weihai-1 01 and 02; Star Epoch 18, 19, 20; and NEXSAT-1. This mission marks the third flight of the Jielong-3 carrier rocket.

Of note, NEXSAT-1 is an Egyptian observation micro-satellite. Oriental Smart Eye Gaofen 01, also known as Yantai 01, is an optical remote sensing satellite with a resolution of <0.5m at an altitude of 500km.

This is the first of a series of posts about the various payloads launched by the third Jielong-3/SD-3 rocket.

First images beamed back by Oriental Smart Eye Gaofen 01, a multi-spectral remote sensing satellite with a resolution of <0.5m.

Zhixing 2A, also known as SmartSat-X1, is a commercial synthetic aperture radar (X-band) satellite for disaster and marine environment monitoring, among other tasks.

Weihai-1 01 and 02 are a pair of satellites operating in tandem. Each weighs around 95kg and features built-in satellite-to-ground as well as inter-satellite laser communication capabilities. They carry high-resolution optical cameras and other payloads to detect and identify maritime targets in real time using onboard AI.

More information on the Star Epoch satellites launched on Feb. 2nd. These are all owned by China Mobile. Star Epoch 19, also known as China Mobile 01, is a verification satellite used to test 5G space internet technologies and has onboard 5G signal processing capabilities, serving as a non-terrestrial 5G base station for direct satellite-to-handset connections. Another of the Space Epoch satellites (not sure which of the remaining two) is nicknamed Star Core (星核), which will be used to verify distributed and autonomous architecture for 6G space broadband internet.

More images of the trio of Star Epoch satellites.

Star Epoch 18, also known as Star Core, used to test 6G and other technologies. It also doubles as an optical remote sensing satellite (see next post):

Tianbing has recently completed calibration tests on the first production batch of the reusable LOX/Kerosene TH-12 engines, which will power the Tianlong-3 launch vehicle that is scheduled to conduct its maiden flight in the 1st half of this year.

Some very nice images from Tianbing's intelligent manufacturing base in Zhangjiagang near Suzhou. By the way, Tianbing has produced a total of 41 TH-12s since the engine was put into batch production.
