The continental space station is in the construction stage, this year will launch the Wentian experimental module and the Dream space capsule and the orbiting Tianhe core module docking, the formation of the mainland space station "T" basic configuration, and the Tianhe core module is equivalent to a vertical under the "T" word, the Sky capsule and the Dream capsule are equivalent to the "T" above the horizontal ends.
The Qtian capsule has been unveiled in early February this year, and it is expected to be launched into orbit in May or June this year to dock with the core module of the Tianhe, and the Dream Module has also recently received new news.
According to the news from China Aerospace News in late February, the positive module of the Mengtian Experimental Module of the Mainland Space Station has been transferred from Shanghai to the Tianjin AIT Center, and the recovery of the module assembly has been completed, and the preparation work for the joint test and inter-system test of the space station assembly is being carried out in an orderly manner. It is estimated that it will be launched one or two months after the launch and smooth docking of the Wentian Experimental Module, which is about August or September this year, and will be launched by the "Long March 5B" Yaosi, and the Qantian Capsule will be docked on both sides of the node module to form a "T" basic type.
We see that the "T" character is the left and right "short horizontal" short of the "one horizontal" above, and the "one vertical" below is long, but the "T" shape composed of the continental space station is not like this, because the "two short horizontals" above are actually longer than the vertical below, and the volume is also larger.
Let's take a look at the data, the length of the core cabin of the Tianhe is 16.6 meters, which is higher than the 5 floors, but the length of the "Ask the Sky" experimental cabin is 17.9 meters, which is 1.3 meters higher than the former, and the height of the dream cabin is basically the same as that of the Sky Capsule.
The diameter of the large column segment in the thickest part of the Core Cabin of the Tianhe is 4.2 meters, which is wider than the carriage of the high-speed railway or subway, and the diameter of the large column segment of the Qingtian Experimental Cabin is also 4.2 meters, but the length of the large column segment is longer than the large column segment of the Core Cabin of the Tianhe, but the large column segment on the Dream Capsule is longer than the Qingtian Capsule, so in terms of volume, the Dream Capsule is the largest of the three modules.
Although the continental space station as a whole is not as large as the International Space Station, but the international space station is large because there are many modules, if you talk about a single module, in fact, the core module of the continental space and the international space station have been large enough for all the modules of the International Space Station, then the Q space capsule and the dream space capsule are of course larger than them, so in fact, the three modules of the continental space station are the largest in space, and it should be the dream capsule as the most, it is likely to be the largest single spacecraft in space at present.
Dream sky experimental module by the China Aerospace Science and Technology Group Co., Ltd. eight academies to grasp the general development, is the new era of "big country heavy equipment", its orbital tasks are mainly in microgravity basic physics, space materials science, microgravity fluid physics and combustion science and other aspects of scientific research and experiments, it is composed of pressurized sealing cabin (work module), cargo airlock cabin, load cabin, resource cabin four parts, of which the pressurized sealing cabin is the main cabin, is the main site for scientific research experiments in the cabin, equipped with a large number of scientific research cabinets.

Cargo airlock compartment is an innovative design, by the inner hatch (located between the cargo airlock compartment and the sealing compartment), the outer hatch (open can lead to the outside of the cabin), the load transfer mechanism and the pressure relief and repression device four parts of the composition, its volume is very large, its inner hatch using a large opening square design, which facilitates the large size of the cargo transport, there are data revealed that the overall maximum size of the cargo in and out of the cabin is 0.9 meters× 1.15 meters × 1.2 meters, which is more than the current International Space Station Hope cargo size in and out of the airlock module, The maximum allowable size of the cargo as a whole is 0.576 meters× 0.83 meters × 0.8 meters.

The load transfer mechanism of the airlock chamber is a handling device for cargo in and out of the cabin, with a variety of functions such as telescopic, rotating and fine-tuning, and the cargo out of the cabin can be grabbed by the robot arm and transferred to the unfoldable exposure experimental platform, and can also be transferred to the predetermined extravehicular load hanging point.
The Montien cargo airlock module also comes with a number of large-area expandable exposure experimental platforms, which also makes it larger in space, some of which face the zenith direction to facilitate the reception of cosmic rays, and the other faces the Earth side, which is more numerous than the Inquisition, which is more efficient and less expensive than the Hope cargo airlock module on the International Space Station.
In addition, the dream capsule also has a large load, multi-point clamping, load transfer mechanism with rotation function, etc., which are innovative highlights in the field of manned spaceflight.
