Tiangong-1 Space Station Reentry

1. Official designated reentry area for Tiangong-1: 'Point Nemo' is a watery graveyard for titanium fuel tanks and other high-tech space debris.

One place China's Earth-bound and out-of-control spacelab, Tiangong-1, will probably not hit on Sunday is the forlorn spot in the southern Pacific Ocean where it was supposed to crash.

Officially called an "ocean point of inaccessibility," this watery graveyard for titanium fuel tanks and other high-tech space debris is better known to space junkies as Point Nemo, in honour of Jules Verne's fictional submarine captain.

Point Nemo is further from land than any other dot on the globe: 2,688 kilometres (about 1,450 miles) from the Pitcairn Islands to the north, one of the Easter Islands to the northwest, and Maher Island—part of Antarctica—to the South.

"Its most attractive feature for controlled re-entries is that nobody is living there," said Stijn Lemmens, a space debris expert at the European Space Agency in Darmstadt, Germany.

"Coincidentally, it is also biologically not very diverse. So it gets used as a dumping ground—'space graveyard' would be a more polite term—mainly for cargo spacecraft," he told AFP.

Some 250 to 300 spacecraft—which have mostly burned up as they carved a path through Earth's atmosphere—have been laid to rest there, he said.

By far the largest object descending from the heavens to splash down at Point Nemo, in 2001, was Russia's MIR space lab, which weighed 120 tonnes.

"It is routinely used nowadays by the (Russian) Progress capsules, which go back-and-forth to the International Space Station (ISS)," said Lemmens.

The massive, 420-tonne ISS also has a rendezvous with destiny at Point Nemo, in 2024.

In future, most spacecraft will be "designed for demise" with materials that melt at lower temperatures, making them far less likely to survive re-entry and hit Earth's surface.

Both NASA and the ESA, for example, are switching from titanium to alumium in the manufacture of fuel tanks.

China hoisted Tiangong-1, it's first manned space lab, into space in 2011. It was slated for a controlled re-entry but ground engineers lost control in March 2016 of the eight-tonne craft in March 2016, which is when it began its descent toward a fiery end.

The chances of anyone getting hit by debris from Tiangong-1 are vanishingly small, less than one in 12 trillion, according to the ESA.

"Nemo," by the way, means "no one" in Latin.

5. Reentry near Mutuaura, Tuamotu Archipelago.
根据中美权威官方分析,本次落点的位置如下: 周围几乎没人,如果有这附近岛屿人拍的照片到可能是真的再入现场照片,其他地区都是假的

Official 1st April 2018 report from the French Polynesia TV channel Polynésie la 1ère:

Debris of Tiangong-1 have crashed west of Maupiti, seen by several eyewitnesses describing the reentry as a meteor shower.

A fisherman told Woullingson Raufauore, the Maupiti Mayor, by radio that debris have crashed near his boat, close to Maupelia [also known as Maupihaa], as he saw the impacts on the sea.

This was the scariest experience he has ever been through, but unharmed, he tried nonetheless to retrieve parts the debris from the ocean "without success". He returned to the island in the same afternoon.

At 08:15, 2nd April 2018, Beijing time, it was 0:15 UTC, and 12:15, 1st April 2018 French Polynesia Time.

6. Le satellite Tiangong-1 s’est écrasé au large de Maupiti. Published on Apr 1, 2018

Jean-Yves Le Gall, President of the Centre National d’Etudes Spatiales (CNES), the French space agency, since 2013, and also Chair of the Council of the European Space Agency (ESA) and President of the International Astronautical Federation (IAF), said in this regard, on 4 April 2018, before the French National Defense and Armed Forces Committee of the National Assembly:

I admit that the way this station has reentered remains for me mysterious ...

But in recent days, the whole world, and France in particular, has lived to the rhythm of the reentry of the Chinese space station Tiangong-1, with patent untruths written in newspapers.

For their reentry in the atmosphere, all the spacecrafts under control are directed towards the point called "Nemo" in the South Pacific, that is to say in the ocean, far from any inhabited land. This is where the Mir station was deorbited. And today, we are being told that this Chinese space station, theoretically out of control, fell, coincidentally, at Nemo point! The probability that this happens randomly is about 1%. We have launched investigations and we may know one day the truth. But I doubt that chance alone contributed to this lucky reentry!

J’avoue que la façon dont cette station est retombée reste pour moi mystérieuse...
Or ces derniers jours, le monde entier, et la France en particulier, a vécu au rythme de la retombée de la station spatiale chinoise Tiangong-1, avec des contre-vérités patentes écrites dans les journaux.
Pour leur rentrée dans l’atmosphère, tous les objets sous contrôle sont orientés vers le point dit «Nemo» dans le Pacifique sud, c’est-à-dire dans l’océan, loin de toute terre habitée. C’est là qu’on avait précipité la station Mir. Et aujourd’hui, on nous explique que cette station chinoise, théoriquement hors de contrôle, est tombée, comme par hasard au point Nemo! La probabilité que cela arrive spontanément est d’environ 1 %. Nous avons lancé des investigations et nous saurons peut-être un jour de quoi il retourne. Mais je doute que seul le hasard ait contribué à cette chute appropriée!




There is no secret that Soheil has already postulated the existence of an undisclosed mechanism that is responsible for the impossible odds behind the Tiangong-1 reentry.

Indeed, Soheil posted months before the reentry that it would reenter over the South Pacific. This was confirmed on 1st April 2018.

Furthermore this uncontrolled spacecraft reentry over the South Pacific was preceded by the 15 January 2012 uncontrolled reentry of the Russian Phobos–Grunt Mars Probe, again against impossible odds.

4. An official map of the Phobos-Grunt reentry released by Roskosmos by 20:00 Moscow Time on Jan. 15, 2012.
Notice the similarity with Tiangong-1 regarding the relative location of the impact zone.


Following the 15 January Phobos–Grunt reentry, the US Strategic Command confirmed a reentry time of 17:46 GMT, referring to an altitude of 80 km at 46°S and 87°W, near the South American coastline. This corresponds to a pass at 10 km altitude about seven minutes later – very close to ESA’s prediction.

“While this was an uncontrolled reentry, the location of the potential impact area was largely over ocean, with a correspondingly low probability of any detrimental effects,” said Prof. Heiner Klinkrad, Head of ESA’s Space Debris Office in Darmstadt, Germany.


This time, the CZ-5B Tianhe R/B also out of control has nonetheless reentered over an uninhabited/least populated territory, near the Maldives.

To further prove the existence of this tool responsible for the controlled reentry of unresponsive deorbiting space objects, we will have many more opportunities in the coming months:

1. First eleven launchers of the CSS program.

This includes 2 more CZ-5B rockets within 2 years.

If all CZ-5B rockets' 2nd stage were to reenter over the same area in the Indian Ocean or Pacific Ocean, one would have to question:

Whether there is a deorbiting secret system controlled by an unknown organization

This organization is probably not from China

The official prediction by China Manned Space (CMS): 34.43°N, 28.38°E is located between Cyprus and Heraklion.

发布日期: 2021-05-09


At 7:24 on May 9, 2021, the final stage wreckage of the Long March 5B Yao-2 carrier rocket orbits: the height of the perigee is about 130km, the height of the apogee is about 160km, and the inclination angle is 41.5°. The estimated time of re-entry is at 10:12 ± 15 minutes on May 9, and the center of the re-entry area is located at 28.38° east longitude and 34.43° north latitude.


But this was only a copy from the wrong prevision by Space-Track.org, between Cyprus and Heraklion:

New update by @SpaceTrackOrg:
2:13 AM · May 9, 2021
New update by @SpaceTrackOrg:

Reentry: 9 may 02:11 UTC ± 1 hour

Reentry is imminent.

4. Post reentry reported time and location.

To sum up, Soheil claims that:

If it exists, this organization is therefore probably transnational

Then this deorbiting network is probably located geographically all over the world, possibly at least partly if not all in space

Furthermore, the deorbiting network might be using laser or some other directed energy as vector

Introduction of Tianzhou-2 Cargo Spacecraft
May 30, 2021
The docking of China's newly-launched cargo spacecraft Tianzhou-2 and its Tianhe space station is fully automatic and the spacecraft has a specialized smart cargo managing system to replenish the station, said experts.
The Tianzhou-2 cargo spacecraft, carried by the Long March-7 Y3 rocket, blasted off from the Wenchang Spacecraft Launch Site in south China's Hainan Province at around 20:55 Beijing time on Saturday, according to the China Manned Space Agency (CMSA).

Tianzhou 2 cargo ship docks with Tianhe core module, becoming first visiting spacecraft to station

2021-05-30 09:13:49

Tianzhou 2, a robotic cargo ship launched on Saturday evening, docked with Tianhe — the recently deployed core module of the country's permanent space station — early on Sunday morning, according to the China Manned Space Agency.

The cargo ship flew with a Long March 7 carrier rocket that blasted off at 8:55 pm at a coastal launchpad at the Wenchang Space Launch Center in the southernmost island province of Hainan.

After a 10-minute flight atop the 53-meter rocket, the craft entered a low-Earth orbit, unfolded its solar panels and then began to execute the rapid autonomous rendezvous and docking procedures that lasted about eight hours, the agency said in a statement.

Tianzhou 2 successfully docked with Tianhe's rear hatch at 5:01 am. Next, it is programmed to conduct autonomous refueling operations and carry out some tests on equipment, according to the statement.

When astronauts from the Shenzhou XII spacecraft board on Tianhe, they will move living materials and mission payloads from Tianzhou 2 to the core module.

Tianhe, or Harmony of Heavens, was lifted by a Long March 5B heavy-lift rocket at the Wenchang launch center on April 29. It is the first part of the Chinese space station, named Tiangong, or Heavenly Palace.

Before docking with Tianzhou 2, Tianhe had carried out a series of tests to verify its designs for rendezvous and docking maneuvers, astronaut accommodation as well as experimental equipment.

Hao Chun, director of the manned space agency, said previously that the Shenzhou XII spacecraft, carrying three men, will launch and dock with Tianhe early next month. The crew will stay in the module for three months.

Tianzhou 2's launch was originally scheduled for the early morning of May 20, but mission commanders decided to postpone the launch shortly before the predetermined ignition time because a technical problem on the rocket was detected.

Over the past 10 days, engineers and technicians from the China Academy of Launch Vehicle Technology, which designed and built the rocket, raced against time to pinpoint and solve the problem, according to the academy.

A Tianzhou cargo spaceship consists of two parts — a cargo cabin and a propulsion section. It is 10.6 meters long and has a diameter of 3.35 meters. With a liftoff weight of 13.5 metric tons, the craft is able to transport up to 6.9 metric tons of supplies to the space station, according to Bai Mingsheng, Tianzhou's chief designer at the China Academy of Space Technology.

With a designed life of more than 1 year, Tianzhou 2, the country's second cargo spaceship, is carrying 6.8 tons of supplies including 2 tons of propellants, more than 160 packages of living and experiment materials and two 100-kilogram extravehicular suits for astronauts to perform activities outside the core module.

During its linkup with Tianhe, the cargo ship will also hold scientific experiments and technology demonstration operations, according to Bai.

The designer said that when Tianzhou 2 departs from Tianhe, it will carry wastes from the module and burn up during the atmospheric reentry.

Hao from the manned space agency said the Tianzhou 3 cargo ship will be launched in September to dock with Tianhe. The next month, another three-astronaut team will fly to the core module on Shenzhou XIII to stay there for six months.

Two large space labs will be launched next year to connect with the module. 2022 will also see two manned missions and two robotic cargo flights to continue construction of the space station, which is scheduled to be completed around the end of next year.

China's most adventurous space endeavor, Tiangong will consist of three main components — a core module attached to two space labs — with a combined weight of nearly 70 metric tons. The entire station is set to work for about 15 years, mission planners have said.

Tianzhou 2's predecessor, Tianzhou 1, was China's biggest spacecraft when it entered service and was launched at the Wenchang launch center in April 2017.

It carried out several docking and in-orbit refueling maneuvers with a Chinese space laboratory in a low-Earth orbit from April to September that year, making China the third nation capable of in-orbit refueling, after the former Soviet Union and the United States.


China Space Station: What does Tianzhou-2 cargo spacecraft look like?

Space 15:41, 30-May-2021

China's Tianzhou-2 cargo spacecraft, the "delivery guy" for China's space station, docked with the newly-launched Tianhe core module early Sunday morning, eight hours after its launch from the Wenchang Spacecraft Launch Site.

The Tianzhou-2 cargo ship has a length of 10.6 meters and a width of 14.9 meters when its two solar arrays are fully deployed. With a maximum takeoff weight of 13.5 tonnes and a payload capacity of 6.9 tonnes, it is the world's largest cargo spacecraft in service.

It is composed of two segments, a cargo compartment with a diameter of 3.35 meters and a propulsion compartment with a diameter of 2.8 meters. Supplies are loaded inside the pressurized cargo section and propellant in the propulsion section.

The cargo compartment has a room of around 40 cubic meters, with 208 lockers to store different categories of goods.

Various supplies for the astronauts and space experimental gear are stored inside the lockers. There are also two spacesuits for extra-vehicular activities, each weighing more than 100 kilograms.

It also delivers space food, including many traditional Chinese dishes. From staple to non-staple food, meat to vegetables, the menu design is of high quality and appetizing for astronauts. Famous stir-fried Chinese dishes like shredded pork with garlic sauce and Kung Pao chicken are both on the menu.

In the past, astronauts often had difficulties finding the things they wanted quickly because of the large quantity and variety of goods onboard. Tianzhou-2 has solved the problem by using an intelligent cargo management system. There is a QR code on each locker, and astronauts just need to scan the QR code with their phones to find out what's inside every locker.

Except for delivering daily supplies and science equipment for the astronauts, another critical task for Tianzhou-2 is to replenish the propellant for the Tianhe core module.

There are eight storage tanks in the propulsion compartment, with 3.5 tonnes of propellant loaded, 2.5 tonnes of which is to refuel the Tianhe core module. The remainder is for its own operational needs.

The cargo craft will operate in orbit for one year. Its power supply capacity is no less than 2,700 watts. It can also carry out multiple in-orbit refueling missions.

A powerful propulsion system

A powerful propulsion system is a must for such a big spacecraft as Tianzhou-2 to conduct maneuvers and dock with the Tianhe core module.

Tianzhou-2 is equipped with 36 engines, including four enormous power orbital control engines used for maneuvers like changing orbit and some small power engines for fine-tuning its position.

Interesting, a crew launched to it just the other day.

I couldn't help but pause to think on the differences between the space nations, the fact that they are going their own ways is a cause for concern as much as it may not be one. Competition in this field is fine, but the path of which each of them take is obviously another. Their stations won't share the spacecraft dock structure. Perhaps for the UFO's.:giggle:

IDK what do you mean with this reply. The Tiangong modular station (I will continue to call it "Tianhe" after its core module to distinguish with Tiangong 1 and Tiangong 2) is able to be docked with Shenzhou and Tianzhou. The docking system used by the Chinese space agency is probably copied from the Soyuz spacecraft, according to my analysis of the following image shared by Soheil_Esy (it is difficult to guess from which side this image is taken BTW):

Edit: I've just heard that three astronauts arrived at the Tianhe module. Now they will be staying at the station for three months. See the AFP report published by NDTV: https://www.ndtv.com/world-news/chi...cessfully-with-tiangong-space-station-2466024

According to an image from Wikimedia Commons, the final configuration of the Tiangong space station (yes, I'm no longer using "Tianhe" for the whole station) consists of only three modules: Tianhe, Wentian and Mengtian, far less than the number of modules at Mir (7) or the ISS (17, excluding the truss segments and other unpressurised components).

there is a difference between the stations, for example, like a mobile phone from the 80s and a modern mobile phone. progress does not stand still
