China leads India by massive margin in space race

[Placemat]

China is 3 times as big as India and has 3-5 times more resource than India but has same population as India. So, China is obviously very resource rich comparatively.

Putting man in space is only a gimmick. The idea of space technology is to use it for better communication and security. How will man going to space change that? Putting man into space is only meant for prestige and not for utility and hence it does not count

Most of China's resource is not theirs. Its tibets

Commentary

Not even in the same league that is.

India humiliating itself endlessly. In the piloted space race, 16 years after China's first astronaut, ISRO still unable to catch up and further delaying its first manned space launch. Now no earlier than 2022!

23rd February 2019

Even as the Indian Space Research Organisation (ISRO) is pushing for completion of the human space programme by the end of 2021, design changes required for the project might delay it further, say scientists at Defence Research and Development Organisation (DRDO).

Meanwhile in the lunar race, six years after China's first lunar landing, ISRO's lunar ambitions further delayed, as the lander just broke its two legs!

Apr 4, 2019

we found that Vikram (the lander) needed to be strengthened in its legs.

Vikram, the Lander on India’s ambitious mission that envisages to land a probe on Moon, has suffered minor injuries in two of its legs during a test late February, putting Chandrayaan-2 on the bench at least until May. But the need to find the most suitable launch window could see the mission take off only in the second half of the year.

lol, by same logic then most of India is not Indian, you occupy what use to be various individual kingdoms since 1947, free Kashmir, South Tibet, Sikkiam first then we can talk about Tibet and Xinjiang.

No, Tibet only has timber (tree wood) as resource. All other resource is from mainland China and Xinjiang

Most of chinese resources, especially oil are bought from Saudi.

Do you even know how stupid you have been in making the above nonsensical childish comments?

None of india's ventures into space has carried any human beings.
None of india's ventures into space has done a SOFT landing.
All of your space ventures have been lifted by underpowered rockets (comparing to ours).

All of the above take varying degrees of much more difficult and advanced space science and technology and your country has shown none of those!

And yet your world hunger index is worsening year on year:

India ranks 103 on global hunger index

Oct 15, 2018

According to the report, prepared by Welthungerhilfe and Concern Worldwide, India is among the 45 countries that have "serious levels of hunger".

India has been ranked at the 103rd position among 119 countries on the Global Hunger Index, says a report.

China is a Superpower and India is a Banana Republic. You can't compare both.

But we never intended it. We are not jokers like you who spend money just for show off. Our priorities was communication, earth observation, planarity exploration, navigation, military appreciation etc. We are not jokers like you guys who attempts and fail and when others succeede , expose b**t hurt by making foolish statement. What happened to your Mars mission which you guys were supposed to carry out in 2017? You couldn't even do with Russian rocket. Not only that but you are unable to attempt in next 8 years. We have a focus on making space launches cheaper. Our new vehicle will reduce LEO and sun synchronous launch cost by 90 pc. You can boast about your man mission which Russins did for you. Other thing you can boast is your heavy lift vehicle which has 100 pc failure rate. We just launched 28 satellites in 3 different orbits . When you do half of that, come and boast here. We are using fourth stage of our Rocket like satellite. It will work like a satellite for 6 months in the orbit these are the achievements your shirt space agency cannot think even in the dream. so you can just boast but you cannot do anything.

Most of chinese resources, especially oil are bought from Saudi.

China produces 4MBPD oil out of 12MBPD it consumes. Indian total consumption is 4MBPD despite having same population as China. This shows that China has enough oil for its decent economy. The extra exort economy may be funded by imported fuel but that is it. Remaining everything else is China producing 30-50% of the mineral resource of the world! With such enormous natural resource, how can you say China is resource poor? China is the third country in terms of resource richness after Russia and USA.

None of india's ventures into space has carried any human beings.
None of india's ventures into space has done a SOFT landing.
All of your space ventures have been lifted by underpowered rockets (comparing to ours).

Indian objective is communication and defence. All other activity is just show off. For what India needs, it has enough technology. As I said above India is resource poor to show off

It's funny because Chinese heavy lift rocket is 99.9% success rate, while Indian with your cheap low tech payload rocket is something Chinese mastered 40 years ago. You have 100% failure rate in lunching same heavy rocket like the chinese one, so don't kid yourself, you are at least 20 years behind in heavy rocket. And "Chinese can't carry out Mars mission despite Russian rocket", lol, no idiot, it's Russian rocket that exploded, not Chinese satellite that exploded. So Chinese Mars mission failed because of Russian rocket, not despite. Without American NASA deep space system, you can't even take your satellite out of earth orbit, Indian Mars mission is a success of NASA not you little Indian space program. Lower cost, like I said, when you can't compete with Chinese on space technology, you compete dirt cheap service, who cares, Indian are dirty cheap, low quality low tech, slave labor wage nation, all you have is quantity, not for your technology, why would your space program be any different? Chinese, Russian and American don't compete on cheapness, that's why these 3 countries don't offer dirt cheap slave labor services like the Indian, we compete on technology, that's why we can put man in space, while you Indian are 20 years behind and still counting.

Well, for India, the scenario for Space exploration is a little different from, say, USA. ISRO’s primary goal has always been using space technology for larger good of the people. Although, in recent times, it has modified slightly to reach Moon and Mars for space exploration, there is still a huge challenge to get funded for a mission which only results in News, and no real gain for public.

There are several key things where India, as a space fairing nation, still needs to excel first before taking larger strides in space exploration

• Medium and Heavy lift launch vehicles - ISRO currently has PSLV, GSLV and Mk-III vehicles. These vehicles are capable of sending 2–4 ton satellites to LEO and GEO. But they are not yet powerful enough to send a manned mission to Moon. Mk-III is capable of sending a manned mission in Low-earth orbit, but this vehicle is yet to become operational.
• Human rated rockets - To take astronauts in space, a rockets needs to be reliable enough to be marked Human rated. That is simple a measure of how often the vehicle has failed in all of its flights.
  - PSLV has a good track record, but it does not have sufficient power.
  - GSLV has slightly more power, but has a bad track record. Getting to human rated reliability is tough for GSLV
  - Mk-III has had only one developmental flight, and can attain this reliability in future
• Technology for Human Space Mission - ISRO has till now tested the crew module once, that too in a suborbital flight. There are a LOT of things that need to be developed before the Crew Module can even be developmentally tested.
  Besides the crew module, a lot of other technologies, like Space Suits, Space Environment Systems, thermal tiles etc. need to be perfected before any Human Space flight attempt
• Increased frequency of launches - Whenever ISRO attempts a mission with an objective other than commercial satellite launch, the question of funding is often raised. Unless ISRO achieves a good rate of launches per month (or year), which improves both the revenue and reliability, it is difficult to get funded for exploratory / developmental missions.
• Following the example - Going to Moon has only been attempted by a few. Sending humans to Moon has, mostly, been an attempt to prove oneself better than other nation in times of Cold War, no real justified technical reason otherwise. Once that was achieved, the Moon missions itself were halted by US and USSR. Unless we have a very strong reason to send our astronauts out there, human Moon mission is a far away thing for India to attempt.

In other words,

Going to the moon again seems much more likely to be our most expensive scientific endeavor rather than the greatest

Death by hunger is India’s tragic reality

It is pertinent to realise that 34 out of 1,000 children born in the country die in the mother’s womb itself. Nine lakh children below the age of five die much before they can comprehend the meaning of independent India and approximately 19 crore people in the country are compelled to sleep on an empty stomach.

Three innocent girls died last week in Delhi’s Mandawali area. The postmortem revealed that their stomachs did not have even a single trace of food. (Reuters)


The history of the nation won’t record the names of Shikha, Manasi or Parul in its pages. Why should it be bothered about them? It is used to chronicling only the affairs of heroes, villains and court jesters. The joys and sorrows of ordinary people don’t usually find a place in our historical tomes.

You may be wondering which section of people am I talking about on Monday morning. Let me inform you: three innocent girls died last week in Delhi’s Mandawali area. The post-mortem revealed that their stomachs did not have even a single trace of food. In other words, they had not eaten for many days. You can well imagine what these girls underwent in their in final moments! They might not have understood the dictionary meaning of the word ‘hunger’, but they lost their life because of it.

At the time these girls were dying of starvation, their mentally ill mother, too, was with them in their dilapidated hut. Owing to her mental ailment as well as a language problem, the native of West Bengal couldn’t even seek help from her neighbours. When the girls were about to die, Mangal, their father, was away looking for work on the streets of the national capital.

Mangal had left his home in rural West Bengal two years ago and moved to New Delhi in search of employment. For lack of any other job, he had become a rickshaw-puller. Even the rickshaw was snatched away by local goons. On the one hand, his source of income dried up, on the other, the rickshaw owner was putting pressure on him to return the money. Even his landlord threw him out owing to his inability to pay the rent.

Who says the Capital cares for the entire nation?

A few other questions are tormenting my mind. Is this the ground reality in the world’s sixth biggest economy? The truth about the governance of popular West Bengal Chief Minister Mamata Banerjee is that people are being forced to migrate from the state. When will the central and state governments, busy fighting for power in Delhi, talk about these issues? Which politician will take the lead to ensure that nobody else dies of hunger? On Thursday, some MPs raised this issue in Parliament, but it was more political posturing than a serious debate on hunger. Why don’t our honourable lawmakers display some unity on such poignant issues?

Since Mangal and his family are neither Rohingya refugees from Myanmar, nor those displaced from Kashmir, nobody has the time or inclination to pay attention to their plight. The doctors who conducted the post-mortem on the children were shocked to see that their fat levels had crashed to zero. Or in other words, despite the absence of any food in their stomachs, their fat levels had kept them alive for a few days. And when even the fats vanished, the girls went into a coma. Doctors told reporters that the girls were suffering from such severe malnutrition that their bones were visible under their skin. Why did these children, aged two, four and eight have to die such a tragic death?

Until the time these lines were being written, Mangal was absconding. Despite knowing very well that the girls died of starvation, the police conducted another autopsy. We have no objection if they treat the deaths of a destitute’s family with suspicion, but who is responsible for ensuring that those who snatched away Mangal’s cycle rickshaw are also punished? It is being said that he was a drug addict. Whose responsibility is it to punish those peddling drugs to him? Poverty can kill you in a number of ways. Penury often drives such people to drug addiction and the repercussions are suffered by the family members of the poor.

It is a fact that 3,000 children die of malnutrition in the country every day. Let me point out the difference between malnutrition and hunger here. Clever governments are afraid of telling people that death by hunger is a bitter fact of life in the country even today. That’s why the post-mortem reports always say that the person died of malnutrition.

It is pertinent to realise that 34 out of 1,000 children born in the country die in the mother’s womb itself. Nine lakh children below the age of five die much before they can comprehend the meaning of independent India and approximately 19 crore people in the country are compelled to sleep on an empty stomach.

From Kalahandi to Delhi, death by hunger is fast becoming a tragic reality in the country. When will our governments make an effort to overcome this crisis?

And we are planning to build our space station earlier than expected:

China’s space station gets the green light in surprise announcement

www.news.cn
In a surprise move, the China Manned Space Engineering Office (CMSEO) announced it will be starting the process of building its own space station sooner than expected. It expects to launch the first mission imminently and aims to have a space station completed by 2022.

Although China has made its desire to build a space station well known, aiming for a first launch this year is faster than was expected. It was only in 2016 that China’s Tiangong-2 space lab was launched, and the lab will de-orbit in July. In the meantime, the Chinese are expected to launch a commercial-grade rocket similar to those used by SpaceX, but one designed to be cheaper. But first, they will have to perform drills and joint tests which they expect to begin in the latter half of this year and to select and train their astronauts in a process that has already begun.

The aim is to create a space station which can hold up to three astronauts at a time and which will last for 10 years. The station will consist of three modules (one cabin and two labs), and its purpose is to host research into topics like life sciences and biotechnology. Surely it is also hoping to be a competitor to the International Space Station, which China was not involved in.

The announcement was made through Xinhua News Agency, China’s state-run news service, and it could have a serious impact on the international politics of space programs. However, China does plan to share the facilities of the station with other countries: “China is committed to making the country’s space station an international platform for scientific and technological cooperation, according to the CMSEO,” the Xinhua News Agency said. As part of this aim of co-operation, the CMSEO “will work with the United Nations Office for Outer Space Affairs to complete the application selection of China’s space station and launch a number of co-operation projects.”

The next key data in the project will come at the end of 2019 when the “Long March-5B” carrier rocket will perform its maiden voyage in preparation for the space station mission.

Can india make an atomic clock?

China's atomic clocks more accurate than ever
Source: Xinhua| 2018-07-26 00:56:55|Editor: Mu Xuequan

http://www.xinhuanet.com/english/2018-07/26/c_137348209.htm



BEIJING, July 25 (Xinhua) -- The Chinese Academy of Sciences announced that an atomic clock has lost the equivalent of only one second in 30 million years during its two years in orbit on Tiangong-2, China's space lab.

Unlike the most atomic clocks, this clock uses cold atom technology to ensure its ultra precision. Hot-atom clocks have almost reached their limits in regard to long-term stability.

Modern time keeping systems on Earth and the global navigation satellite system rely heavily on atomic clocks.

The high accuracy of the cold atom clock is attributed to the microgravity environment in space as well as the coldness of the atoms the clock uses.

Under microgravity conditions, cold atoms are pushed by lasers. By observing their performance, it is possible to obtain more precise time signals than on Earth.






China just launched the world’s most accurate clock into space
By Katherine Ellen FoleySeptember 17, 2016

https://qz.com/783269/china-launched-cacs-the-worlds-most-accurate-cold-atomic-clock-into-space/


Every clock on Earth is flawed. Even science’s most accurate atomic clocks are beholden to our planet’s gravitational pull, and end up slowing down ever so slightly over time. That’s why researchers from Shanghai decided to send one up into space.

On Sept. 15, Chinese researchers launched a cold atomic clock into orbit around Earth, where it will only slow down by one second every billion years, as opposed to every 300 million years like the current gold-standard of atomic clocks. The Cold Atomic Clock in Space (Cacs), as it is called, will likely become humanity’s most accurate timekeeping device.

Atomic clocks are largely used for calibrating extremely sensitive electronics, like global positioning systems (GPS), or conducting experiments in hyper accuracy-dependent disciplines like particle physics and geology. According to the South China Morning Post, the Chinese government intends to use Cacs to improve their own national GPS, which currently operates at levels below the system employed by the US.

Atomic clocks were originally created to run on the exact measure of a second as agreed upon by the entire scientific community. Seconds used to be measured as a tiny fraction of a day. The trouble is, the average day includes a lot of variation, depending on where you are and the earth’s axial wobble, caused by its magnetic poles and, more recently, melting ice sheets.

Scientists realized that the way that electrons (the tiny negatively charged particles that surround atoms) jump back and forth between different energy states in molecules or atoms, was a much more precise way of calculating a second. These oscillations end up appearing like vibrations that occur at a constant rate—as long as molecules or atoms are at a constant temperature. Since 1967, the official definition of a second has been “9,192,631,770 vibrations of a cesium 133 atom.”

Laser-cooled “cold” atomic clocks are generally considered to be the most accurate clocks that exist—other clocks and watches, like the kind anyone could buy in a store, tend to slow down over time. Although it’s often just a couple of seconds, that inconsistency won’t do in a research setting.

But alas, on Earth, even cold atomic clocks are prone to slowing down ever so slightly. Because of the force Earth’s gravity applies to atoms, the National Institute of Standards and Technology’s NIST-F2 atomic clock in Boulder, Colorado will slow down by a second every 300 million years.

Cacs, which will orbit our planet gravity-free, will use rubidium atom vibrations to keep time, and will slow down much more slowly than Earth-bound atomic clocks. It’s also a lot smaller—about the size of the trunk of a car, whereas the NIST-F2 takes up an entire room.

Cacs was sent into space on the second Chinese space laboratory, called Tiangong-2, launched from Jiuquan Satellite Launch Centre in Inner Mongolia. Although there are currently no humans aboard, the China National Space Administration plans to send two astronauts to the lab in October to conduct various experiments for a month, as the next step towards launching a full-fledged space station in 2020.

Three Atomic Clocks Have Failed Onboard India's 'Regional GPS' Constellation
A replacement satellite will be launched in the second half of 2017, according to ISRO chairman A.S. Kiran Kumar. The cause of the problem remains unclear...

BEIJING, July 25 (Xinhua) -- The Chinese Academy of Sciences announced that an atomic clock has lost the equivalent of only one second in 30 million years during its two years in orbit on Tiangong-2, China's space lab.

Unlike the most atomic clocks, this clock uses cold atom technology to ensure its ultra precision. Hot-atom clocks have almost reached their limits in regard to long-term stability.

Modern time keeping systems on Earth and the global navigation satellite system rely heavily on atomic clocks.

The high accuracy of the cold atom clock is attributed to the microgravity environment in space as well as the coldness of the atoms the clock uses.

Under microgravity conditions, cold atoms are pushed by lasers. By observing their performance, it is possible to obtain more precise time signals than on Earth.






China just launched the world’s most accurate clock into space

Every clock on Earth is flawed. Even science’s most accurate atomic clocks are beholden to our planet’s gravitational pull, and end up slowing down ever so slightly over time. That’s why researchers from Shanghai decided to send one up into space.

On Sept. 15, Chinese researchers launched a cold atomic clock into orbit around Earth, where it will only slow down by one second every billion years, as opposed to every 300 million years like the current gold-standard of atomic clocks. The Cold Atomic Clock in Space (Cacs), as it is called, will likely become humanity’s most accurate timekeeping device.

Atomic clocks are largely used for calibrating extremely sensitive electronics, like global positioning systems (GPS), or conducting experiments in hyper accuracy-dependent disciplines like particle physics and geology. According to the South China Morning Post, the Chinese government intends to use Cacs to improve their own national GPS, which currently operates at levels below the system employed by the US.

Atomic clocks were originally created to run on the exact measure of a second as agreed upon by the entire scientific community. Seconds used to be measured as a tiny fraction of a day. The trouble is, the average day includes a lot of variation, depending on where you are and the earth’s axial wobble, caused by its magnetic poles and, more recently, melting ice sheets.

Scientists realized that the way that electrons (the tiny negatively charged particles that surround atoms) jump back and forth between different energy states in molecules or atoms, was a much more precise way of calculating a second. These oscillations end up appearing like vibrations that occur at a constant rate—as long as molecules or atoms are at a constant temperature. Since 1967, the official definition of a second has been “9,192,631,770 vibrations of a cesium 133 atom.”

Laser-cooled “cold” atomic clocks are generally considered to be the most accurate clocks that exist—other clocks and watches, like the kind anyone could buy in a store, tend to slow down over time. Although it’s often just a couple of seconds, that inconsistency won’t do in a research setting.

But alas, on Earth, even cold atomic clocks are prone to slowing down ever so slightly. Because of the force Earth’s gravity applies to atoms, the National Institute of Standards and Technology’s NIST-F2 atomic clock in Boulder, Colorado will slow down by a second every 300 million years.

Cacs, which will orbit our planet gravity-free, will use rubidium atom vibrations to keep time, and will slow down much more slowly than Earth-bound atomic clocks. It’s also a lot smaller—about the size of the trunk of a car, whereas the NIST-F2 takes up an entire room.

Cacs was sent into space on the second Chinese space laboratory, called Tiangong-2, launched from Jiuquan Satellite Launch Centre in Inner Mongolia. Although there are currently no humans aboard, the China National Space Administration plans to send two astronauts to the lab in October to conduct various experiments for a month, as the next step towards launching a full-fledged space station in 2020.

Recent report in Chinese news paper China times have revealed the horrible hygiene situation in China. People are dying by eating substandard food an things like gutter oil.

It's funny because Chinese heavy lift rocket is 99.9% success rate, while Indian with your cheap low tech payload rocket is something Chinese mastered 40 years ago. You have 100% failure rate in lunching same heavy rocket like the chinese one, so don't kid yourself, you are at least 20 years behind in heavy rocket. And "Chinese can't carry out Mars mission despite Russian rocket", lol, no idiot, it's Russian rocket that exploded, not Chinese satellite that exploded. So Chinese Mars mission failed because of Russian rocket, not despite. Without American NASA deep space system, you can't even take your satellite out of earth orbit, Indian Mars mission is a success of NASA not you little Indian space program. Lower cost, like I said, when you can't compete with Chinese on space technology, you compete dirt cheap service, who cares, Indian are dirty cheap, low quality low tech, slave labor wage nation, all you have is quantity, not for your technology, why would your space program be any different? Chinese, Russian and American don't compete on cheapness, that's why these 3 countries don't offer dirt cheap slave labor services like the Indian, we compete on technology, that's why we can put man in space, while you Indian are 20 years behind and still counting.

Stupid low IQ CPC school educated people even don't know a simple logic that to get 99.9 pc success rate, you need to have atleast launched 1000 rockets. However, we can forgive them keeping their low standard of education in CPC reeducation camp.

You guys are semi-literate. You can just read and write., Add and subtract. Your breatherrn has have provided the example of your literacy by quoting figure of 99.9 pc. Success of your rocket launches.
