In this launch, the caps had a parachute system with which the different technologies for recovering the fairings are still being tested.

Notice the blue tarp on the fairing? Chinese official reports state that they are testing parachute recovery of the fairing again this time.

This is also the last of the YG-30 triplets "at this stage". Also on board is Tianqi-15 which will join its LEO comms/IoT constellation.

CASC confirms that this is the last launch in the Yaogan-30 series of satellites with which it completes 30 Yaogan-30 satellites from its first launch on September 30, 2017.

XICHANG, July 19 (Xinhua) -- China successfully launched a new remote-sensing satellite group from the Xichang Satellite Launch Center in southwest China's Sichuan Province at 8:19 a.m. Monday (Beijing Time).

The satellites were sent into orbit by a Long March-2C carrier rocket. This is the 10th group belonging to the Yaogan-30 family, and will survey the electromagnetic environment and verify relevant technologies by adopting multi-satellite network mode.

Also aboard was Tianqi-15, a satellite belonging to the Tianqi constellation, which will serve the Internet of Things data collection.

The Long March-2C carrier rocket, developed by the China Academy of Launch Vehicle Technology, measures 43 meters in length and has a takeoff mass of 242 tonnes.

The rocket is capable of sending two tonnes of payloads to the solar synchronous orbit at an altitude of 500 km.

Monday's launch was the 380th mission of the Long March rocket series that also marked the conclusion of the launch of the Yaogan-30 family.

The Long March-2C has sent all 10 groups of Yaogan-30 satellites into orbit with high accuracy since September 2017, with a 100 percent launch success rate.

A new object has been found at 463x592 km which has got the E letter and, obviously, is the 2nd stage.
Former E is now B and probably it's Tianqi 15.
What was the former B is unknown.

This is the first successful recovery of the fairing in China, also the parachute used in this test is different from the one used in May 2021.
