Chinese Space Program
The reporter learned from the University of Science and Technology of China on March 20 that Pan Jianwei, Peng Chengzhi, Liao Shengkai and other scientific research teams at home and abroad cooperated with a number of scientific research teams at home and abroad to realize real-time satellite-to-ground quantum key distribution between quantum micro-nano satellites and miniaturized and movable ground stations for the first time in the world, and realized up to 1 million bits of secure key sharing during a single satellite pass, and established a quantum key at a distance of more than 12,900 kilometers between China and South Africa, completing the encryption and transmission of image data "one at a time". It paves the way for the practical application of satellite quantum communication networking.

First picture looks like a mutant flatfish/flounder - where is SPCA International when you need them? But seriously, folks, is there any way to keep the nondemocratic Chinese (and while we're at it, also the Russians) out of outer space for good? Asking for a dear Western European friend...

Official graphics showing the planning of Tianwen 2 (May 2025, rendez vous with 2016HO3 in 2026, sample return in 2027, rdv with 311P in 2033), 3 (late 2028, return in mid 2031) and 4 (2029, arrival at jupiter in 2035, at Uranus in 2045)
The Jupiter half of the probe will eventually orbit Callisto and send penetrator probes that will impact the surface.
In the 2030s, NASA's Europa clipper will focus on Europa, ESA's Juice on Ganymede and Tianwen 4 on Callisto.
Earlier this month, CNSA sent calls for international experiment rideshare on Tianwen 3, up to 20kg of scientific payloads will be caried on both the Earth sample return orbiter and the interplanetary cruise stage of the lander-ascender. It is considered as a sign that the CNSA is confident in the mission and its launch date.
A presentation by the Deep Space Exploration Laboratory (one of the main organisation working on the Tianwen program) of the main upcoming "flagship" planetary missions, the later ones haven't received approval yet.

-2033: Venus atmospheric sample return, it was already outlined in a recent decadal survey; it may also be a consolidation of a couple previous chinese venus mission proposals, it is still unknown if it will only sample the upper atmosphere from low orbit or if it will reenter into the middle atmosphere, the goal of searching for microorganisms makes it seem like the later but the timeline would certainly be extremely ambitious.
-2038: This seems to be the mars equivalent of ILRS, similarly to it, the station is likely to be initially uncrewed.

, it would notably be launched on a direct trajectory by a super heavy launcher. Note that this isn't the first chinese proposal for a Neptune mission, and is certainly not set in stone.
This isn't an exhaustive list of chinese deep space missions, the Chinese Academy of Science is working on the Solar Polar Orbit Observatory, a chinese equivalent to the old ESA-NASA Ulysses mission, while CNSA and the DSEL are working on an asteroid redirect mission comparable to NASA's DART planned for 2027

So we have some (advertise) spec for JZYJ upcoming FFSC methalox engine. This company is purely engine manufacturer, whose open cycle methalox engine the Longyun-70 is adopted by many of Chinese space start up and even used by state institution like SAST for their methalox reusable rocket hopper.
Now let see if they can deliver…

The crew will be announced 1-2 days before launch. The shenzhou 19 crew is expected to return to earth on May 1st
In other news, Landspace announced the assembly of the test model of the 1st stage of their Reusable Medium-Heavy launcher Zhuque-3, it is expected to do a static fire (at a dedicated facility, thought to be in Shandong) to qualify the design ahead of the inaugural launch currently planned for the 2nd half of the year.
Landspace announced that later versions of this launcher will be able to launch up to 21.8t of payload to low earth orbit, however the first version,with less powerful engines, will only be able to launch 9.4t to low earth orbit.

We already were suspecting GW constellation to have some classified reconnaissance and target tracking capabilities

Succesful launch at 09:17 UTC of Shenzhou 20 carrying astronauts (from left to right)
王杰 Wang Jie (born in 1989), 3rd group, 1st flight, former engineer at CASC. He notably worked on the Xuntian telescope.
陈东 Chen Dong (bon 1978), 2nd group, commander who has already flown on Shenzhou 11 and 14, he is likely to become the chinese astronaut with most time spent in space by the end of this mission
陈中瑞 Chen Zhongrui (born 1984), 3rd Group, 1st Flight, former Air Force pilot and instructor.

Those should be the two buildings being built around 19.639071 110.948848. The launch site is down around 19.610093 110.944456, these two buildings will connect to the new launch site by a crawler track under construction.
