LOL.......
Typicall yellow stinky logic

India's first moon mission discovered water. Even after crashing MIP, ground breaking discovery came out of it. What about China probe: what have they achieved unique in their first moon mission: what difference did it make:?

.........LOL
there was a program yesterday on the Discovery sinces network called man v/s space and this episode dealt with resources on the moon it was said that the Jade Rabbit was a actually looking for (He-3) or Helium-3 light, non-radioactive isotope of helium according to Wikipedia
The total amount of energy produced in the 21H + 32He reaction is 18.4 MeV, which corresponds to some 493 megawatt-hours (4.93×108 W·h) per three grams (one mole) of ³He. If the total amount of energy could be converted to electrical power with 100% efficiency (a physical impossibility), it would correspond to about 30 minutes of output of a gigawatt electrical plant per mole of 3He. Thus, a year's production (at 6 grams for each operation hour) would require 52.5 kilograms of helium-3. The amount of fuel needed for large-scale applications can also be put in terms of total consumption: electricity consumption by 107 million U.S. households in 2001

Picking up luner sample was done in 1970s by US & Russian. Others after spending millions are doing it now.

About soft landing, re-entry and small liquid motors are perfected long ago. Since perfection upto Mars was shown, soft landing on moon or back wont be a problem.

Isro does have plans for two rovers in one flight. Lets wait and see.

About doing large, we didn't see much benifits from expensive humans in space programme.
then what is the benefit of merely orbiting around Mars? You guys are simply hilarious. you contend that soft-landing on moon is worthless because Russians and Americans did that in 1970s, but do you know that Americans did "orbiting around the mars" as early as in 1971? what does that make indian mars mission?

anything will be a problem unless you have successfully done it, which you haven't yet. what you are planning is nothing, only what you have done counts.

Start counting the days....

ISRO is to set record on 28/12/17 we won't be launching one, but three rovers creating the record.

If you ask about records, then ISRO has a long list of breaking the old records and setting new ones.

Instead of all the rant, I think highly advanced country like yours, should have participated in the Lunar Xpress contest. Then again, if 3000 participants submitted their interest, all of'em without any previous knowledge on space missions, then why there is a lack of interest from China.
the contest is organized by an American company, space program cooperation between China and US was halted since 1990s.

why not wait and see how that launch come out, I will give India credit it deserves on something it has done, not something it plans to do.

Chang'e 1 created the most accurate and highest resolution 3-D map ever of the lunar surface, until it was surpassed by the LRO.[8]
Chang'e 1 conducted world's first passive, multi-channel, microwave remote sensing of the Moon.[9]

let me remind you that.your orbiter crashed into moon before more than one year before it was scheduled to do so. if we apply the same criteria to indian moon mission as it is being applied to Chinese space mission, India basically failed. Chinese Tiangong-1 at least served its due period.

and another thing I wish to point out is that it's inaccurate to say indian probe found water on the moon because the device that detected water was actually developed by Americans. technically speaking, it's American who first find water on the moon. and if I recall it correctly, 6 of the 11 devices that indian probe was carrying were non-indian.

Ohhh We can launch a mission to Mars in copybook manner in first attempt and can not put a man in 600 km orbit for shitty 3 days like you people? Go and have some coffee. Man mission was never and is not our priority. You have nothing to show so you are bringing man mission every time here. We have no plan to do it for coming 5 years. Just launch 104 satellite with one rocket and then come for discussion. Just test sremjet engine and reusable launch vehicle and then come here and fart. You guys are unable to achieve what we have achieved with Just 1/6th of budget. You guys are nothing against ISRO. Your copycat launches of satellites are no more useful than giving chinese public some orgasm.
it's funny that nearly every indian member mentioned the mars mission, I concur that it's a masterpiece of ISRO, and I think it's the only masterpiece so far. trivial success like the 104 satellites launching doesn't add to the capability of ISRO. 104 satellites are a lot of satellites, but all of they are micro satellites, the payload of them all combined is insignificant.

at least it is on the moon, have you ever put anything on the moon with crashing it?
Yes,
Ever heard of MIP (Moon Impact Probe) with Chandryaan intentionally crashed on Lunar Soil?
I hope you get difference between hard & soft landing.

Or the your way, yes we crashed on the lunar surface in 2008.
MOON IMPACT PROBE (MIP)


The impact probe of 35 kg mass will be attached at the top deck of the main orbiter and will be released during the final 100 km x 100 km orbit at a predetermined time to impact at a pre-selected location. During the descent phase, it is spin-stabilized. The total flying time from release to impact on Moon is around 25 minutes.

The primary objective is to demonstrate the technologies required for landing the probe at a desired location on the Moon and to qualify some of the technologies related to future soft landing missions.

Major Objectives:


Design, development and demonstration of technologies required for impacting a probe at the desired location on the Moon.


Qualify technologies required for future soft landing missions.


Scientific exploration of the Moon from close range.

Payload Configuration Details:

There will be three instruments on the Moon Impact Probe


Radar Altimeter – for measurement of altitude of the Moon Impact Probe and for qualifying technologies for future landing missions. The operating frequency band is 4.3 GHz ± 100 MHz.


Video Imaging System – for acquiring images of the surface of the Moon during the descent at a close range. The video imaging system consists of analog CCD camera.


Mass Spectrometer – for measuring the constituents of tenuous lunar atmosphere during descent. This instrument will be based on a state-of-the-art, commercially available Quadrupole mass spectrometer with a mass resolution of 0.5 amu and sensitivities to partial pressure of the order of 10-14 torr.

The dimension of the impact probe is 375 mm x 375 mm x 470 mm

MIP System Configuration

The Moon Impact Probe (MIP) essentially consists of honeycomb structure, which houses all the subsystems and instruments. In addition to the instruments, the separation system, the de-boost spin and de-spin motors, it comprises of the avionics system and thermal control system. The avionics system supports the payloads and provides communication link between MIP and the main orbiter, from separation to impact and provides a database useful for future soft landing.

The mission envisages collecting all the instrument data during descent and transmits to main orbiter, which in turn will transmit them to the ground station during visible phases.
Impact Probe Mission Profile


It's still there, means already landed, thing India has pending is "soft landing" even which is ready to be launched after a long wait.

Second, there is no benifit of bragging about soft landing on a body without atmosphere. Real deal is soft landing on a body with atmosphere.

Regarding mocking for "India will do" , I guess you must be mocking after mission fails because it's high time when mission is really close to execution.

http://defenceforumindia.com/forum/threads/indian-lunar-space-probes-and-exploration.77530/
Here is the track thread.
it's funny that nearly every indian member mentioned the mars mission,
Like every Chinese mentions docking or soft landing.
I concur that it's a masterpiece of ISRO, and I think it's the only masterpiece so far. trivial success like the 104 satellites launching doesn't add to the capability of ISRO. 104 satellites are a lot of satellites, but all of they are micro satellites, the payload of them all combined is insignificant.
I don't think launching 104 satellites is about any payload capacity. We have bigger launchers than the launcher we used for that mission.
Case is for tech used & economy, it isn't that easy to launch so many satellites there without damage. And if you will launch a bunch of few microsats with multiple launches, I guess it might much much more than hitting in a single one.


Look Madam, putting objects in space is probably costliest part of any business.

Even if a Agnecy A offers 80% cost of Agency B, 100% of orders will go to A even if customers have to be in waiting queue because it saves millions.

I don't get anything wrong here if just by cutting down cost, we can occupy 80-90% if not entire microsat market.
For the same reason; ;)

6 of the 11 devices that indian probe was carrying were non-indian.
Buying equipments back then cuz we didn't have back then for first exploration mission,
what difference does it make?
PRC got a lot lot more technical expertise & intellectual property from West & USSR while India was under sanctions.

You got so many waviers, we got sanctions.
You got permanent UNSC Seat, while NSG was created to create trouble for India. Just because potential US asset against Soviets.
February 15, 1996. A Chinese Long March 3B carrying a $200 million Loral satellite explodes 22 seconds after lilftoff.

March 14, 1996. President Clinton shifts control over regulating the export of communications satellites from the State Dept. which was primarily concerned with national security aspects of such exports, to the Commerce Dept., which is concerned with the economic benefits.

May 10, 1996. The Loral-led review commission investigating the February rocket explosion completes and passes on to Chinese officials its report, which according to the April 13, 1998 New York Times, discusses “sensitive aspects of the rocket’s guidance and control systems, which is an area of weakness in China’s missile programs.” The New York Times says that a Pentagon report concludes that, as a result of this technology transfer, “United States national security has been harmed”.

May 23, 1996. President Clinton calls for renewal of MFN for China, saying that renewal would not be “a referendum on all China’s policies,” but “a vote for America’s interests.”

June 8, 1996. China conducts an underground nuclear test.

July 21, 1996. Johnny Chung, according to the New York Times, brings Liu Chao-ying to two DNC fundraisers, including a $25,000 per couple dinner. Liu Chao-ying is a Lieutenant Colonel in the People’s Liberation Army and an executive at China Aerospace, which owns the Great Wall Industry Corp. that makes Long March rockets. Her father is the top commander of Chinese military forces. The New York Times says that Chung has told the Justice Dept. that Liu gave him the better part of $100,000 he contributed to the DNC in the latter part of 1996, and that the source of the money was the PLA.

July 29, 1996. China declares a moratorium on nuclear testing after conducting another nuclear test.

August 8, 1996. According to AP, Clinton meets again with Long Beach officials to advocate turning over the naval base to COSCO.

September 24, 1996. At the UN, President Clinton joins with the foreign ministers of China, France, Russia and Great Britain in signing the Comprehensive Test Ban Treaty forbidding all testing of nuclear weapons.

November 5, 1996. President Clinton wins reelection. According to the Center for Responsive Politics, the single largest Democratic donor during the election cycle was Loral CEO Bernard Schwartz, who gave $632,000 in ‘soft money’ to the Democratic Party between 1995 and 1996. The State Dept. issues regulations shifting responsibility for satellite launching licenses to the Commerce Dept.

January 1997. The Panamanian government awards the contract to operate the Atlantic and Pacific ports of the Panama Canal to a Hong Kong company, Hutchison Whampoa. China takes control of Hong Kong six months later. The United States, which is set to relinquish control of the canal next year, does not protest.

March 25, 1997. While in Beijing for a meeting with Premier Li Peng and President Jiang Zemin, Vice President Gore attends signing ceremonies for Boeing’s $685 million sale of five jetliners to China’s state-owned Civil Aviation Administration as well as a $1.3 billion joint venture between General Motors and China’s state-owned Shanghai Automotive Industry Corp.

May 1997. According to the April 13, 1998 New York Times, a classified Pentagon report reveals that Hughes and Loral scientists “had turned over expertise that significantly improved the reliability of China’s nuclear missiles” following the February 1996 rocket explosion. Hughes and Loral deny the New York Times report when it is published in 1998.

May 19, 1997. President Clinton announces that he will authorize MFN renewal for China.

October 1997. Chinese President Jiang Zemin makes a state visit to the United States. During the trip, he stops at a Hughes site to discuss satellites.

January 15, 1998. After China promises that it will no longer aid Iran’s nuclear program, President Clinton certifies that China is a reliable partner for nuclear technology exchange.

February 19, 1998. Despite opposition from the Justice Dept, President Clinton signs a waiver approving the launch of a Loral satellite from a Chinese rocket and reportedly authorizing the transfer of the same type of technology that the Pentagon said had “harmed” US security and that the Justice Dept. was investigation Loral and Hughes for their illegally transferring in 1996.
Two years later, same America put India under heavy sanctions in 1998.
There's a lot more to share, yet everytime you'll be boasting for gifted IPR's as your innovation and mocking others cuz they try & fail.

Not Unique, you simply did what others did, but in better sense simply because you launched later and had better access to newer Cameras and Better Storage and Transmission Tech. That is bare minimum any new launch should have done. LOL.......................

Are Chinese propah-gandoos so dumb?
When did Chandrayaan crashed into moon? Last Checked it was still in orbit. Only communication broke down as Overheating cooked of some of its Communication gear.
and another thing I wish to point out is that it's inaccurate to say indian probe found water on the moon because the device that detected water was actually developed by Americans. technically speaking, it's American who first find water on the moon. .
If wishes were horses chinese 50 centers would have big eyes to read and understand better. MIP (Moon Impactor probe was first to detect presence of water molecules. Spectral Analysis of MIP impact had indicated presence of water molecules. It was much later fully confirmed with help of American sensor also.

I agree. Such achievements only serve as trivia. They do not signify any leap in capability. Unless of course, it would have been an achievement of the Chinese. Then you would have had to hail it as a path breaking achievement of the CCP.

Anyway, the mars mission although something significant and indeed path breaking for the Indian space community is not very significant when compared to the efforts of giants like NASA and ROSCOSMOS who have done the very same thing many decades ago, with significantly less computing power and inferior systems of those times.
ISRO would do well to not do something which others have done a long time ago and then beat the drum about doing it now. As a demonstration of capability, it was impressive, but we have far more miles to travel if we want to be respected as a space exploring nation.

As for the Chinese, their goal is gimmicks. And that is all they can afford with their copycat inferior technologies. The whole world knows what is the brand value of "Made In China" is without a non-Chinese brand name. It amounts to toys which fall apart in two days, phones which become non-functional in two weeks and space stations which are planned to fall down after two years.

we not only did it in first attempt, but use just 10% of what it cost to US.
It took the imagination of our young generation by storm. They are now planning for things beyond their reach.

30 character rule sucks
That's a great effort by ISRO. You're a reasonable fellow @Indx TechStyle, and I don't consider you a fanboy in the least.

I don't dispute ISRO's achievements in space. What I'd like to fact-check is the prevalent theory that ISRO's Mars probe, the Moon impact probe and launching 100+ micro-satellites on a single launcher make ISRO superior or more technologically advanced that the CNSA. That's a fallacy which I'm sure any objective person familiar with space programmes can point out immediately.

A few high profile missions do not make ISRO superior to the CNSA. The frequency and diversity of the space missions undertaken by the CNSA alone testify to its maturity in space flight.




In terms of the constellation of satellites in orbit, both commercial and military, China still has many times over the number of remote sensing, communications, navigation, surveillance and R&D/Scientific satellites in orbit vis-a-vis the India. In terms of experimental space science, eg, quantum communication, gamma-ray studies, x-ray studies into gravitational waves etc) China's state-university based R&D base is much larger and much better financed than its Indian counterpart, which is reflected in the number of scientific/experimental satellites put in orbit by either country.



You would know better than most on this forum the disparity between the two countries in terms of space launch capabilities, ie the number and capability-range of the launch vehicles available to each space agency.

As you know, the testing ISRO is undertaking in preparation for a soft lunar landing, whenever that may be, was carried out by its Chinese counter part back in the early 2000's with the mission initiated in 2013 in the form of the Chang'e3 moon lander mission.






By the time ISRO carries out a soft landing on the moon, the CNSA will probably have completed its mission to return lunar samples to earth through another lunar mission scheduled for early next year.

As to manned space missions, by the time ISRO puts its first man in space, the CNSA will have had years of technical experience and the technology that goes with it under its belt.

But as you've alluded to above, the CNSA and ISRO have had very different development paths, with different levels of access to technology and a vast discrepancy in financing. It doesn't diminish the talent of Indian scientists at ISRO to point out that the CNSA is more advanced in certain space missions. Or vice-versa.


I don't like these "d*ck measuring competitions", because members end up losing all sense of objectivity and fanboys like @HariPrasad-1 start making ridiculous assertions based on wild-eyed nationalism instead of fact-based realities.

ISRO's "demonstration of capability is impressive" but when China puts men and women in space for over a month, or soft lands a rover on the moon, "their goal is gimmicks" and not development of space technologies?

Seems pretty hypocritical. If India had accomplished even half of the marquee space mission the CNSA had, i'd bet everything I own that you wouldn't call them "gimmicks", just as you are not calling the ISRO Mars mission a "gimmick".

Chinese satellites are junk and nobody buys their images inspite of offering free.

I don't remember if I called ISRO superior either, it was just next to a dead space agency until did something in 90s,

It's budget is fraction of CNSA, it's basically new in basically very new in exploration (launching satellites and exploring space are different things). And it might be
just starting baby steps as high profile missions.


But there's a difference between both,
One is regarding payload capacity while other is about control over maneuvers for multi SAT launches. The mission was purely for commercial exposure and I don't guess it was really needed to be trolled, other one is factual incorrectness of @nimo_cn.
I know you stopped posting on PDF. Have been there arguing against one sided discussions for India having some foreign stuff (that even on previous decade) on it's payloads without checking own profile.:) No worries though, fanboys are everywhere. Things on that forum have gone worse and super intelligent "Think Tanks" who can't differentiate between turbofans and pulsejets.

I'm not comparing with anyone, a human is human, from whichever country, he/she's innovative but before demeaning a third world country's effort for buying something who itself fought sanctions alone for decades, I guess history needs to be checked.
Be it UK or China, we never had that much of hospitality from US.
Nor I don't care that much, our space agency is pretty good with budget it's provided and will be up with more funding gradually.

I agree with everything in this post bar one. "I solemly swear" that I've never posted or registered on PDF.

*Yes, that's a Harry Potter reference. "marauder's map".
