Another Indian high on drugs

They are currently only 2 countries capable manned mission to space. Russia and China.
China is the first Asia and third countries to have successful manned mission to space.
China is also the only Asia countries with successful soft landing and put a rover on moon.
Hope our Indian friends can get that right and stop making up nonsense with chest thumping bragging.

Though both have so far not been able to reach anywhere close to MARS.
Your statement sounds like a mare’s nest.
Yet both are able to carry out manned mission. You are just selective to suit your agenda. No countries can be considered space technology advance by only doing unmanned mission. Get your facts right.

Even before comparing your space tech with ours, you must fulfill the criteria of getting as close to MARS as Mangalyaan did.
We will talk once you achieve that feat.
Why can’t talk about manned mission? Let me repeat that again. No nation can be considered a space power without having carry out independent manned mission.
Little India come back and talk to me when you carry out your first. There is a reason why both American and Russian are considered space powerhouse given the amount of manned mission and technological feat they achieved involving manned mission. China are on the way to join them, not even Indian come close.

You are not in position to arbitrarily change the commonly accepted criteria when these are not in India's favor!
This reminds one of the heavy-handed and hegemonic practices of the Washington regime in the diplomatic and economic arena.
But let us be clear, the Red Planet's average distance from the earth is 225 million kilometres.
The farthest apart they can be is about 401 million km, and this is India's record in distance for any spacecraft launched by ISRO.
Meanwhile, China's Lunar probe, Chang'E-2 launched in October 2010, was first sent around the Moon at a 100 km orbit above the Moon.
Seven months after its departure from the Earth, the spacecraft left the lunar orbit in June 2011 to fly to the Lagrangian Point (L2), about 1.5 million km away from the Earth, the furthest point any Chinese spacecraft had ever reached.
After spending 235 days at L2, Chang’e 2 departed in April 2012 to explore the 10 million kilometres deep space.
In December 2012, the spacecraft flew by a small Near Earth Asteroid 4179 Toutatis at a distance about 7 million kilometres away from the Earth. Chang’e 2 flew by the asteroid at a distance of 770 m.
This has never be done by India, nor Russia. And the manoeuvres required are of several order of magnitude more challenging in term of accuracy, nothing comparable in term of difficulty to a simpler orbital insertion around such larger, more visible and massive object as the planet Mars!
After this outstanding technological prowess, only mastered by a few nations, the probe Chang’e 2 continued to fly away from the Earth and reached a distance of 100 million kilometres, thus becoming a satellite of the Solar System.
The spacecraft had enough propellants left to continue functioning up to a distance of 300 million kilometres.
Conclusion
Meanwhile, I will urge ISRO to hurry up in training its Vyomanauts, as the most coveted fourth place as a manned spacefaring nation might soon be within North Korea and Iran's grasp!

Notice the many similarities with the North Korean spacesuit: from the head part, torso, flag location and size, etc. Video published on Feb 10, 2018
Commentary
Both Iran and North Korea have disclosed their intention to send a man into space by 2021.
As stated by Iran, 10 pilots have already been pre-selected by 2017, and two of them will be the final asronauts.
Taking into account that two years in average are required to train an astronaut, the selection process for North Korea should have started, as hinted by the 2018 New Year show.
In addition the 10 astronauts of the show corroborates the number of 10 Iranian pilots. Therefore one should assume that North Korea is also currently training 10 pilots.
Clairvoyance
The next spacefaring nation to achieve the status of fourth only nation in the world to send a man into space with its own launcher, will be...

Instead of living in an alternate revisionist world, by simply recklessly overlooking the outstanding Chinese milestones in spacefaring, strongly advise India to abandon its frantic denial mode and prepare itself for the inevitable outcome, the way Europeans do!

Alternate History: The Empire of China conquers Mars
10-02-2017
In the desert, in a hostile world, man has managed to gain a foothold and to sustain life. After decades of cold war, of technological races to dominate the world, the Empire of China won its showdown with the European Union: after the Moon, Mars has just been colonized.
For years, this unmatched feat has mobilized all the resources of the country. Barely 20 years after the first step on the moon, the Empire of China, from the height of its 5,000-years history, today shows the world the grandeur of its civilization. His success is such that we are already talking about the Chinese century.
But all this has never happened! 900 years ago a small grain of sand will cause a series of events that will decimate more than a third of the Chinese population and slow down its development for centuries.
1174, Mongolia. A clan leader is poisoned by a rival tribe. He dies under the eyes of his young son named Temüdjin. A few decades later, riders ransack a nomad camp, they leave with a captive, a beautiful woman, her name is Börté.
1214: Beijing is taken and pillaged by the Mongols. In the years that follow, China will lose a third of its population.
These three tragic elements are intimately linked, they are key moments in the life of a unique conqueror in the history of mankind, Genghis Khan!

TIANGONG-1 REENTRY
TIANGONG-1
Tiangong-1 is currently predicted to reenter the Earth’s atmosphere around April 4th, 2018 ± 1 week.
Object Description
Type: Payload
Int’l Designation: 2011-053A
NORAD Number: 37820
Launched: 2011 September 30 @ 03:16:03.507 UTC
Site: Jiuquan Satellite Launch Center, China
Mission: Tiangong-1, First Chinese Space Station
Mass: 8500 kg at launch (18,740 lbs)
Length: 10.5 m (34 ft)
Diameter: 3.4 m (11 ft)
Solar panels: 2 panels (approx. 7 m x 3 m)
Diagram of Tiangong-1 – Image credit: Wikimedia Commons
Tiangong-1 is predicted to reenter in around April 4th, 2018 ± 1 week*.
This prediction was performed by The Aerospace Corporation on 2018 March 15.
*Note: This prediction assumes an uncontrolled reentry (no thrusting).
Tiangong-1 Reentry Hazard
There is a chance that a small amount of Tiangong-1 debris may survive reentry and impact the ground. Should this happen, any surviving debris would fall within a region that is a few hundred kilometers in size and centered along a point on the Earth that the station passes over. The map below shows the relative probabilities of debris landing within a given region. Yellow indicates locations that have a higher probability while green indicates areas of lower probability. Blue areas have zero probability of debris reentry since Tiangong-1 does not fly over these areas (north of 42.7° N latitude or south of 42.7° S latitude). These zero probability areas constitute about a third of the total Earth’s surface area.
When considering the worst-case location (yellow regions of the map) the probability that a specific person (i.e., you) will be struck by Tiangong-1 debris is about one million times smaller than the odds of winning the Powerball jackpot. In the history of spaceflight, no known person has ever been harmed by reentering space debris. Only one person has ever been recorded as being hit by a piece of space debris and, fortunately, she was not injured.
Tiangong-1 Altitude Prediction
Tiangong-1 Altitude History & Adjustments
Dotted lines indicate dates of probable orbital maneuvers.
*Prediction and altitude history graphics updated weekly*
Mission Background
- Tiangong-1 is the first space station built and launched by China.
- It was designed to be a manned lab as well as an experiment/demonstration for the larger, multiple-module Tiangong station.
- The spacecraft was launched aboard a Long March 2F/G rocket on 2011 September 30 UTC.
- There are 2 modules that compose Tiangong-1: A habitable experimental module and a resources module.
- It has a habitable volume of 15 cubic meters.
- Tiangong-1 is equipped with 2 sleep stations for astronauts.
- The first Chinese orbital docking occurred between Tiangong-1 and an unmanned Shenzhou spacecraft on 2011 November 2.
- 2 manned missions were completed to visit Tiangong-1: Shenzhou 9 and Shenzhou 10.
Has There Been a Loss of Control?
On 2016 March 21, an official Chinese statement declared that telemetry services with Tiangong-1 had ceased. Based on The Aerospace Corporation’s analysis of Two-Line Element set data from the JSpOC, the last orbital adjustment for Tiangong-1 was made in December 2015. Likewise, amateur satellite trackers have been tracking Tiangong-1 and claim it has been orbiting uncontrolled since at least June 2016. On 2016 September 14, China made an official statement that they predict Tiangong-1 will reenter the atmosphere in the latter half of 2017. China later updated its prediction via an announcement to the UN’s Committee on Peaceful Uses of Outer Space on December 8, 2017. It was not mentioned whether the reentry was to be targeted or remain uncontrolled.
FAQs
Where will Tiangong-1 reenter?
It is a well known scientific principle that any measurement or prediction will always have an associated uncertainty. In the case of most reentering objects, the uncertainty associated with predicting reentry location is extremely large and precludes an accurate location prediction until shortly before the reentry has occured. In general, it is much easier to predict an accurate reentry time rather than an accurate reentry location. Based on Tiangong-1’s inclination, however, we can confidently say that this object will reenter somewhere between 43° North and 43° South latitudes.
How Difficult is it to Accurately Predict a Reentry?
Due to the uncertainties involved it is very difficult to predict the exact timing of a space object’s reentry. There are several sources of uncertainty which include: 1) significant variation in the density of the upper layers of the atmosphere, 2) significant uncertainties in the orientation of the space craft over time, uncertainties in some physical properties of the spacecraft such as the exact mass and material composition, and 3) uncertainties in the exact location and speed of the space station. When aggregated, these factors translate into a reentry timing uncertainty that is roughly 20% of the “time to go” (the time between the date of the prediction and the predicted date of reentry).
Will objects from this reentry hit me or my property?
It is highly unlikely that debris from this reentry will strike any person or significantly damage any property. The only known case of space debris striking a person is Ms. Lottie Williams of Tulsa, Oklahoma who was struck by a small piece of space debris in 1996 but was not harmed in any significant way. The Aerospace Corporation will perform a person and property risk calculation for the Tiangong-1 reentry a few weeks prior to the event.
Is this a controlled reentry?
It is unlikely that this is a controlled reentry. Although not declared officially, it is suspected that control of Tiangong-1 was lost and will not be regained before reentry.
Are there people on board? Are they in danger?
No, no astronauts are currently on board Tiangong-1. The last manned mission departed from Tiangong-1 in June 2013.
Can I see the reentry?
It may be possible to see Tiangong-1 reentering depending on your location, the time of day, and visibility during reentry which will not be known until a few days prior to the event. A more detailed predicted reentry region will be provided a few days prior to the reentry time frame. Visibly incandescent objects from this reentry will likely last tens of seconds (up to a minute or more) in contrast with the vast majority of natural meteors which last mere seconds.
What will this reentry look like?
Depending on the time of day and cloud visibility, the reentry may appear as multiple bright streaks moving across the sky in the same direction. Due to the relatively large size of the object, it is expected that there will be many pieces reentering together, some of which may survive reentry and land on the Earth’s surface. Some examples of reentries can be found here: video 1, video 2.
Are there hazardous materials on board?
Potentially, there may be a highly toxic and corrosive substance called hydrazine on board the spacecraft that could survive reentry. For your safety, do not touch any debris you may find on the ground nor inhale vapors it may emit.
Should I report a sighting of the reentry? If so, to whom?
Yes. Contact CORDS at http://www.aerospace.org/cords/contacting-cords/ – Please report your location and time of the sighting, a description of what you saw, and provide any images or videos you may have captured of the reentry.
Is this the largest man made object to ever reenter from space?
No. The largest object to reenter is the Mir space station at 120,000 kg which reentered on 2001 March 23. In comparison, Tiangong-1 is only 8,500 kg. For further space debris reentry information, consult the table on this page.

Since the hasbara boy keeps reposting the same litanies again and again all over the forum, let me reveal the following, confirming my previous assessment:
The Chinese PLA ASAT laser stations seem to have already proceeded with their first in a series to come corrective laser surgical pinpoint accuracy strikes, as shown in the sudden increased decay rate of Tiangong-1 witnessed by the official TLE of March 12!
▲ It is clearly visible an anomalous burst from the TLE 18070.1268 (March 11) to 18072.1107 (March 13), 6 consecutive TLEs.
▲ After the big variation in the decay rate on March 12, the totally controlled reentry is predicted at a slightly earlier date: 2-3 April 2018
Coincidence? I think not!

Tiangong-1 2018 Reentry V1.3 Part1

1. Introduction
As all these questions can only expose how biased and ill-intentioned the Western propaganda machine is, hell-bent in smearing the ever more outstanding Chinese space achievements (due to desperation and jealousy as always), let us reassure all our Pakistani readers and other foes as well, with some clarifications.
China has been working on developing laser weapons since the 1960s, and the People’s Liberation Army in 2015 published the book Light War that gives a central role to fighting a future war using lasers.
As already disclosed by the media, China is known to have operated at least 3 ASAT laser stations, in Anhui, Sichuan and Xinjiang.
In 2005, Chinese researchers have successfully conducted a satellite-blinding experiment using a 50-100 kilowatt capacity mounted laser gun in Xinjiang province. The target was a low orbit satellite with a tilt distance of 600 kilometers. The diameter of the telescope firing the laser beam is 0.6 meters wide. The accuracy of acquisition, tracking and pointing is less than 5 microradians.
Three researchers, Gao Minghui, Zeng Yuquang and Wang Zhihong disclosed plan for even more powerful ASAT lasers in The Chinese Optics journal in December 2013.
All worked for the Changchun Institute for Optics, Fine Mechanics and Physics – the leading center for laser weapons technology.
The plan proposed the building of a 5-ton chemical laser as a combat platform capable of destroying satellites in orbit. Given funding by the Chinese military, which is in charge of China’s space program, the anti-satellite laser could be deployed by 2023.
In another study that was led by Quan Wen, a researcher from the Information and Navigation College at China's Air Force Engineering University, with the help of the Institute of China Electronic Equipment System Engineering Company, laser used in removal of space debris have been investigated.
The simulation results show that, debris removal is affected by inclination and RAAN, and laser station with the same inclination and RAAN as debris has the highest removal efficiency. It provides necessary theoretical basis for the deployment of space-based laser station and the further application of space debris removal by using space-based laser.
Although high secrecy is strictly enforced, one could compare the case of Tiangong-1 space laboratory with the ill-fated Phobos-Grunt Mars probe, that reentered over the South Eastern Pacific Ocean on 15 January 2011.
There was no random reentry over highly populated area. This time Tiangong-1 will also reenter over the Pacific Ocean, in a remotely controlled mode.
This suggests that China will secretly use its laser ASAT stations, to produce a series of thrusts generated by heating until vaporizing the outer part of the spacecraft, thus lowering the perigee of Tiangong-1. Notice Tiangong-1 passes every day up to five times over China, heading south-Eastward toward the south Pacific.
Upon reaching the ultimate ~140 km altitude threshold, where a complete orbit is no longer possible, the coup de grâce will be given by piercing the forward part of the pressurized module, thus allowing all the remaining gaz to escape at high velocity, and generating an additional negative vector thrust (think of a coca cola bottle).
Alternately, by piercing the propellant tank (i.e. Hydrazine) would even provide a more powerfull thrust, but the targeting requires a higher accuracy.
If this procedure succeedes, this would eventually allow a safe reentry half an orbit later over the predesignated area over the Pacific Ocean.
What makes the preparation for this highly risky space billiard operation possible is that China can count on its world fastest supercomputers.
As reported by the state television CCTV13, it it took 20 days, instead of the otherwise 12 months, for China's Sunway-TaihuLight, the world's fastest supercomputer, for simulating the numerical reentry prediction, which are in accordance with wind tunnel simulations.
This is the least China could do, as even North Korea has already disclosed its own Korean-style Anti-Meteor Laser System, needed to protect its planned future Lunar base, back in a New Year 2018 show!

Note that the space lab will present its APAS docking ring forward due to the overall aerodynamics and especially the solar pannels at the rear section, therefore allowing a good view and stable laser targeting of the said frontal section.

2. The "12 March 2018" laser strikes event

▲ It is clearly visible an anomalous burst from the TLE 18070.1268 (March 11) to 18072.1107 (March 13), 6 consecutive TLEs.

5. The geomagnetic storm of 19 March 2018
Due to severe space weather caused by solar activities, a geomagnetic storm on 19 March 2018 is resulting in an increased decay rate, accelerating the date of reentry of Tiangong-1, around 3 April±1 day.

2. The "12 March 2018" laser strikes event
Confirming earlier assessment, the Chinese PLA ASAT laser stations seem to have already proceeded with their first in a series of corrective laser surgical pinpoint accuracy strikes, as shown in the sudden increased decay rate of Tiangong-1 correlated by the official TLE of March 12!
▲ It is clearly visible an anomalous burst from the TLE 18070.1268 (March 11) to 18072.1107 (March 13), 6 consecutive TLEs.
▲ After the big variation in the decay rate on March 12, the totally controlled reentry is predicted at a slightly earlier date: 2-3 April 2018

4. Official Chinese statement after the "12 March 2018" event
More smoking gun, or rather smoking lasers!
Chinese official statement, suggesting a successful first series of laser strikes:
"
Descent of China’s Tiangong-1 will not cause damage to earth: expert
March 14, 2018
According to the latest information issued by China’s manned space engineering office, since Feb. 25 to Mar. 4, 2018, Tiangong-1 was orbiting in stable condition and good shape at an average height of about 251.5 kilometers (perigee height: 238.6 km; apogee height: 264.4 km; orbital inclination: 42.79 degrees).
China has been monitoring Tiangong-1, Zhu said, adding that the space lab will burn up after entering the atmosphere and the remaining wreckage will fall into a designated area of the sea, without endangering the Earth’s surface.
Aerospace expert Pang Zhihao explained that an international tradition to handle retired large spacecrafts operated at near-earth orbits is to let them fall to an abyssal zone in southern Pacific Ocean far away from the continents.
Being called the “graveyard of spacecraft”, the water was the falling location for Mir space station and Progress spacecraft of Russia, and the Compton Gamma Ray Observatory of the US, Pang added.

5. The geomagnetic storm of 19 March 2018
Due to severe space weather caused by solar activities, a geomagnetic storm on 19 March 2018 is resulting in an increased decay rate, accelerating the date of reentry of Tiangong-1, around 3 April±1 day.

Radar imagery indicating a good physical integrity of Tiangong-1, allowing the final coup de grâce that will be given by piercing the forward part of the pressurized module, thus allowing all the remaining gaz to escape at high velocity, and generating an additional negative vector thrust (think of a coca cola bottle). This would eventually allow a safe reentry half an orbit later over the predesignated area over the Pacific Ocean.

Tiangong-1 2018 Reentry V1.3 Part2
6. The coup de grâce
▲ Artistic representation of the controlled reentry of Tiangong-1 through PLA ASAT laser beams
Notice a forecast by some Western media, made 24 March 2018, confirming the last pass over China's Tianshan ASAT laser station before ending in the southern hemisphere. But the reentry zone is a little bit farther than in the South Pacific, continuing Northeastward in the South Atlantic, as no coup de grâce laser strikes have been modeled for the numerical simulation.
▲ According to the forecast made by Satview.org on 24 March 2018, the space lab's reentry will occur over the South Atlantic on Monday, 02 Apr 2018 at 21:22 UTC
▲ Other forecasts as of 24 March 2018: ESA 30 March-3 April; Aerospace 3.5 April±3 days; Chinese forum 2 April±1 day
Weather forecast over Tianshan ASAT laser station as of 24 March 2018, indicates that 31 March will be sunny and with some clouds at night, 1 April sunny and rainy at night, 2 April sunny and cloudy at night, 3 April sunny and with some clouds at night, meaning that the conditions for a laser targeting might not be optimal but still feasible.
