No and will probably never.
There is some 3GPP specs regarding satellite in 5G network, but it is about using satellite in place of land based trunk lines such as fibre and microwaves. This Chinese constellation is fulfilling this part of 5G spec.
Physically it is impossible for an ordinary 5G phone to receive signal strong enough from a satellite.
The use case of the constellation is to connect a mobile 5G base station on an ocean liner, airliner, oil rig, naval task force, science expedition in the middle of nowhere with the land based network, allowing usage of ordinary 5G phones or IOT.

You can see a Starlink satellite dish weighs 5kg and is 30x50cm
Great pictures as always but a typo on the company nameThe first six 5G broadband internet satellites from Galaxy Aerospace have been transported to launch site. They will be launched by a CZ-2C rocket in the first quarter of 2022. A constellation of these are envisioned to provide global 5G internet coverage.
It's GalaxySpace
But Iridium phone's bandwidth is tiny compared with a 3G, 4G and 5G phones. Small bandwidth means small antenna needed to reach acceptable S/N.
According to wiki, , Iradium is 25 kilo Baud per second both Uplink and Downlink. Downlink being QPSK and Uplink BPSK. This means Downlink 50 kbps, Uplink 25 kbps. It is below the standard of GPRS in 2G GSM, let alone anything from 3G.
Successful test of some sort of air breathing kerosene fuelled spaceplane engine prototype from Tsinghua University.
Seems to be an air augmented rocket of some sort with an inlet cone, boosted by a solid fuel first stage. However it also said test successfully gathered data on how vacuum environment affects the engine's various performance parameters. So maybe it's got both air breathing and rocket mode.

Wait, spaceplane? This rocket is supposed to be part of a spaceplane?
