Chinese Space Program (CNSA) & Ch. commercial launch and discussion

[steve9728]

CCTV: CASC presented their rocket booster and fairing recovery project at the 3rd Innovation and Creativity Competition hosted by the CASC. They also indicated that this recovery system, which consists of several subsystems through the use of a large parafoil, and remote control, is in the final stage of development.

Teng Haishan (滕海山), deputy chief engineer at CASC's Institute 508 of the Fifth Academy, said the system could reduce the original 30-90km drop zone to a much smaller size and allow it to land in the designated area. "We've got a 'landing bed' in the landing zone. This allows the fairing to land like a mattress and is fully recoverable without damage. So, this will allow the fairing to be reused."

"This technology is now relatively mature, and we already have the ability to recover the 4-ton booster, including the booster of the CZ-3B rocket, the CZ-3C rocket and the CZ-2F rocket - we can recover them all. We are now trying to be able to recover the 3.35m diameter fairing of the CZ-2C rocket, and also the 4m and 4.2m diameter fairings, which are all similar. Both this year and next, we will carry out two booster recovery systems and two more fairing recovery systems, and if there don't have any problems, the design will be finalised. "

Me, CNSA, were already sent two rovers to the moon and one on the Mars. Although the Mars one still doesn't wake up and the first one sent to the moon was unable to walk, but both rover on the moon were all survived several lunar nights - the Yutu-2 is even the "currently operational as the longest-lived lunar rover and the first lunar rover traversing the far side of the Moon."

And I still need to "steal" the "tech" from the Middle East "in one night then put it back together before morning" because it has components from US.

Retarded

It wouldn't be the bad news to leave this valuable opportunity to send a rover to the Moon to a team from our own universities or other research institutions.

I believe this price still have space to be pushed downwards after further narrowing or even resolving the rocket wreckage drop zone issue. As mentioned in the report on the rocket wreckage parachute return system days ago, if in the future this system is maturely applied to every rocket, it could save over a billion RMB per year in launch costs.

The latest research result from Chang'e-5 samples: Beads of Lunar Glass Boost Hopes for Using the Moon’s Water

"Based on an extrapolation of such findings, the research team — headed by scientists from the Chinese Academy of Sciences — estimates that glass beads in lunar soil may contain up to 270 trillion kilograms (595 trillion pounds, or 71 trillion gallons) of water."

If I remember correctly, there was also another robot that could do EVA tasks shown at last year's Zhuhai Airshow. The shape was just had the upper body, but it had hands and could be connected to the robotic arm.

Galaxy Space (银河航天), the satellite manufacturers, in their official weibo said that, these four InSAR would be perform a wheal formation. The primary star will locate in the middle of the wheel and the three secondary stars are evenly distributed on the hub of the wheel. They form the first international formation of satellites on wheels. They also mention in their official wechat account said that, this system "has the capability of 1:50,000 scale mapping of global non-polar areas, which can quickly and efficiently carry out global land mapping with high precision. It has the capability of millimetre-level deformation monitoring, which can provide data support for the investigation and prevention of ground subsidence, subsidence, landslides and other disasters, and is a powerful tool for the early identification of major geological disaster hazards in complex areas. It has the capability of sub-metre high-definition wide-area imaging, which can provide all-weather and round-the-clock high-quality imaging observation of the ground, and the overall technology has reached the international leading level."

More than that, PIESAT is planning to launch more in the future: now is the first stage - launch the first four satellites into 528km to validate the technology. The second stage they plan to launch 16 satellites including 4 C-SAR in co-orbit in 542km×49° LEO. And 4 group, 12 X-SAR sats in total at 522km SSO with 0.3~12m resolution. The final stage they plan to launch 18 including 8 C-SAR satellites like second stage. And 10 high resolution optical satellites which the resolution will be higher than 0.5m. After the completion of this satellite constellation system, it will have capability for global coverage in one day, revisit any place in one hour, and deformation monitoring every day for anywhere may need for Earth observation.

Saw something interesting: the two crews in two different station performed mission in similar time, which the Shenzhou-14 crew and SpaceX Crew-4, had similar photo!

OK, now the Shenzhou 15 crew has carried out two EVA missions under classified conditions. If this rumour-like information is accurate

The idea about designed the fridge with front and back doors. Loading something need to keep in low-temperature before the launch is pretty genius.

Yaogan-34 satellites constellation, which have beautiful white horse on the mission patches!

Officially (although I can see it too) the mission patches are inspired by a famous bronze artefact from the Han Dynasty, the Galloping Horse Treading on a Flying Swallow (马踏飞燕). Interestingly, it does look quite good in profile, but if you can walk up to the front and look at it... It doesn't look too smart hahaha

Confirmed. CMS's official weibo said that, the crew "has carried out the third time EVA activities. Under the close cooperation of the ground crew and cabin astronaut Deng Qingming, the two exiting astronauts, Fei Junlong and Zhang Lu, successfully completed all the established work and returned safely to the Wentian Module."

According to my own little tally, the blue suits are currently used most often, eight times in total.

Currently, the CSS inside is full of the parcel. A "semi-official" Weibo account said "this is expected to be alleviated after the docking of Tianzhou-6." But he doesn't say in what way.

As far as I know, there's also have some BEAM like inflatable cabin experiments in the future. But there's short of docking port right now.

It's also possible that he is doing April fool

Irresponsible guesses about the Shenzhou-16 crew member: Jing Haipeng (co-pilot of Shenzhou-7), Yang Liwei (the first taikonaut, but very unlikely though), and one of the third echelon of taikonauts that has never been publicly listed.

Of course, this guess is pretty idle.

Do some deeper little research about this. Some of the news report said that the Tianzhou-5 cargo ship will maintain in orbit for one year. Comparing to the previous TZs, which were running in the orbit for half a year, so I think the Tianzhou-5 won't de-orbit immediately after the Tianzhou-6 docking with CSS. But to be a co-orbit cargo bay with the station. When the Shenzhou-15 crew finished a week or two for handover the station to Shenzhou-16 crew and leave the station, Tianzhou-5 probably will dock with station again.

So, the news some time ago that the launch date had been brought forward to 2023 was some kind wishful thinking by some media.

[steve9728]

 

Suddenly it occurred to me that their success had quite a "historical milestone" meaning: the first rocket fully using liquid propellent launch successfully in the first mission by private fund in the world. And it's also the first rocket using the liquid oxygen and paraffin launched from JSLC.

via. https://weibo.com/1462552767/MArN5tgoY

The official Wechat account of Space-Pioneer said that this launch made 7 first time in the world and in China:

1. the first successful orbital flight of the world's first liquid launch vehicle for private spaceflight
2. the world's first launch vehicle to apply coal-based space paraffin in flight
3. China's first liquid launch vehicle that does not rely on a launch station
4. China's first launch vehicle with a 3D printed high-pressure supplementary combustion engine
5. China's first launch vehicle with 3-engine parallel engine technology
6. China's first launch vehicle to adopt an all-aluminium alloy surface tension storage box attitude orbit control system
7. China's first launch vehicle to achieve reuse of the rocket structure

They also mention that they were extremely accurate to send the sats in orbit: 

• Ø Half-length axis deviation 267m
• Ø Eccentricity deviation 0.000065
• Ø Track inclination deviation 0.004°

If we push the definitions further refined to use methane, there still have chance for other companies. Don't you think so, Landspace?

Tiangong TV S04E20: Busy, Very Busy, Extremely Busy!

Those at the beginning of the video are valves and tanks for diluents, oxidisers and inert gases for the Combustion Science Rack in Mengtian Module. "More than 40 times of burning experiments are expected to be completed in the station in 2023.", said by the subtitles.

They also show the low temperature storage cabinets in -20℃ in Wentian Module and some footage about the third EVA for Shenzhou-15 crew.

Although we still don't know more details about the tasks of this EVA. However, based on this image of the connector between Wentian and Tianhe, it can be sure that the taikonauts have climb some distance in space this time - at least not limited to the Wentian Module.

One more: the first rocket to implement active controlled de-orbiting on its upper stage in China. "The upper stage of the rocket left orbit within 400 seconds of ignition and orbited the Earth approximately half a revolution before re-entering Earth in the safety area of Antarctica.", said by Space-Pioneer's official Wechat account.

Have to say that this company brough a lot of surprise. Those technologies are actually quite close related with CNSA: such as the coal-based paraffin for this rocket was supplied by the 165 institute, the CASC's sixth academy. So, it's reasonable to assume that the tech about the upper stage wreckage de-orbiting fully under control of the future CZ rockets was tested first time in this launch.

It should have been done so to train Egyptian talent in the satellite field. After all, sending a satellite from China to Egypt and then sending it back from Egypt to China for launch is pretty troublesome.
