2) After breakthroughs in the theory and technology of natural and safe dormancy induction, dormancy can be used for longer-term (months to years) manned deep space exploration and interstellar voyage missions. Based on dormancy-derived hypothermia therapy, its safety, metabolic consumption changes, and nutritional supplementation regimens in normal humans need to be evaluated.
Could you put all of us into dormancy until COVID-19 and rampant hyperinflation phase of the Twenties is over?

Sun Zezhou, Chief Designer of Wentian Mars Explorer and ChangE -3/-4 series Lunar Explorer, held a lecture at an Extraterrestrial Living and Life Supporting Technologies Forum which was part of the 120th Anniversary Ceremony of Nanjing University.

Doctor Sun demonstrated the upcoming Mars Surface Sampling and Returning Plan of China in the lecture.

The MSSRP is scheduled to run during May 2028(Plan Mars Spring) or November 2028(Plan Mars Fall) to July 2031.

The Mars Lander-Ascender Complex will be launched, as Plan Fall, in December 2028, and descend onto Mars surface in September 2029, or as Plan Spring, launched in May 2028 and descend in April 2030 onto the Mars.

Then the Complex will release the Rover. The Rover will explore the Mars like the Tinwen Mars Rover and take Martian soil and rock samples back to the Ascender module.

The Mars Orbiter-Returner Complex will be launched in November 2028 and inject to the LMO in May 2030.

The Ascender will then be launched from the Mars surface in May or June 2030, as Plan Fall, or in October 2030, as Plan Spring. Then the Ascender will meet and dock to the Orbiter-Returner complex and handover the samples to the Returner module.

Then the Mars Orbiter-Returner Complex depart and the Returner go back to the Earth and reentry in July 2031 while the Orbiter stayed as a telecom relay and Mars surveillance satellite for the future Mars exploration.

The explorer is formed by two separate parts: the Mars Orbiter-Returner Complex
, and the Mars Lander-Ascender Complex.

The Mars Orbiter-Returner Complex has two parts: a Mars Orbiter and a Returner to Earth.

The Mars Lander-Ascender Complex has three pars: a Lander, a Mars Rover, and an Ascender.

Both complexes will be launched by one CZ series rocket(CZ-5 as for planned now).

Challenge 1: Autonomous rendezvous and docking at the Mars orbit without GPS and other measurement support.

View attachment 91202
Challenge 2: Sampling on the Mars surface. There will be surface soil sampling, drilling sampling and multi-point mobile sampling for the job. Small dog-shaped robot will be released to take samples.

View attachment 91203
Challenge 3: Ascending from the Mars. A 4.5km/h delta-v will be needed to ascend from the Mars surface. And lacking of the Martian atmospheric data will also be a great challenge.
Well the space race is on, whether the US is ready or not. Of course, China is going at it’s own pace. I wonder if Biden will respond with a big NASA bill, problem is: would it even be effective?

I love how China always leaves infrastructure behind as a secondary objective of many missions:

The mars mission leaves an orbiter, a ground station and UGV/UAV’s behind.
The main detector of the asteroid sample return will probably end of visiting other celestial bodies, or end up being part of some colossal radio network for example.

One they have solved the issues of these missions, I am pretty sure there will be many follow ups, if all it costs is 2 LM5’s and standardized equipment then this is another place that China can transform costs by scaling up fast.

The moon sample returns generated so much scientific interest they could have had 10 or 50 times more scientific collaborations if they had more samples, so I can see first a justifiable scientific need for multiple missions but also this could be combined with building a GPS/EO/6G satellite constellation system with the orbiters as well as large scale ground exploration with the dogs etc, then it is really a good use of money and power.

If China puts a constellation of orbiters in Mars in this way then it is normalizing two way transport between mars and earth, with the first caro of this new logistics route expected for delivery in just 2031. It could be like the China-Europe trains!

Who knows what the dogs will find? whatever it is, samples can probably be returned to labs earth with a lot of automation.

Likewise with the asteroid and comet sample returns, if China builds a network of these asteroid/comet hunting space craft in this method, then it normalizes space mining. That network could be used to provide communications and navigation in the asteroid belt, while each mission returns priceless samples.

I don’t know how big these constellation’s would have to be, 24 is a number that comes up a lot, so that’s 48 LM5 launches for each constellation (just for discussions sake). How fast could they do that? If they can monetize it, and promise future revenue, they can even finance it, and incentive that fast construction and follow up development.

Imagine if a lab in the UAE, or a mining company in Brazil can order a sample from a region of mars and have it delivered in a couple of years. That is worth a lot of money; future revenue streams, which can finance PPP loans today, and that is the core of Chinas new development model and I am sure it will be applied tevery major piece of infrastructure like this.

LM9 would be able to contribute as well, but there isn’t a dependency on it. LM9’s will be in short supply to start, and it gives the commercial space sector an achievable target in the years ahead: beat the LM5.

It’s pretty much fantasy of course, but I think it shows a semi-plausible scenario to that space and mars mining future many dream about, and the cost just doesn’t seem that much to bear.

As USA 270 closed in on Shiyan-12-01 and Shiyan-12-02, the Chinese inspection satellites took off in opposite directions with Shiyan 12 02 moving into position to get a sunlit view of the U.S. surveillance satellite. Shiyan-12-02 positioned itself between the sun and USA 270 providing a perfect imaging opportunity of USA 270.

Is it possible to counter this kinetically?

Just task Sj-21 to take this US Spy sat and throw it into a “graveyard” orbit.
Exactly what the US is afraid China would do -

U.S. military leaders expressed concern when China’s Shijian-21 space debris mitigation satellite grabbed a defunct Beidou navigation satellite and hauled it 3,000 kilometers to the graveyard above the GEO belt.

Removing obsolete satellites from the geostationary belt is a valuable service. The same technology, though, could have more nefarious applications.

“Shijian-17 and Shijian-21, which are satellites with robotic arm technology, could be used in a future system for grappling and disabling other satellites,” U.S. Army Gen. James Dickinson, Commander of the U.S. Space Command, told the Senate Armed Services Committee in March.

Of course it will. The most splendid golden age of the aerospace history of human being was the age when the United States and the Soviet Union competed for the access to the space.

The world wasn't getting better even when the two great powers stopped the money burning space competition in the late 1980s when the Soviet colossus fell. ;)

The head of the China Meteorological Administration, Zhuang Guotai announced that the data produced by the country's two Fengyun series meteorological satellites will be shared with global users.

He made the remarks at the 75th session of the Executive Council of World Meteorological Organization on Monday.

Fengyun 3E and Fengyun 4B are used to help monitor and forecast weather, as well as prevent and mitigate disasters.

Fengyun 4B, which launched in June last year, can capture images of a 250-meter resolution to better aid in monitoring weather.

Fengyun 3E, the world's first civilian early morning orbit weather satellite, which launched a month later in July last year, was designed to improve global weather forecasting by filling in the gap in data at specific times of the day, and assist in ensuring 100 percent global data coverage every six hours.
