The lander module from India's moon mission was located on the lunar surface on Sunday, one day after it lost contact with the space station, and efforts are underway to try to establish contact with it, the head of the nation's space agency said.

The Press Trust of India news agency cited Indian Space and Research Organization chairman K. Sivan as saying cameras from the moon mission's orbiter had located the lander. "It must have been a hard landing," PTI quoted Sivan as saying.

ISRO officials could not be reached for comment.

The space agency said it lost touch with the Vikram lunar lander on Saturday as it made its final approach to the moon's south pole to deploy a rover to search for signs of water.

A successful landing would have made India just the fourth country to land a vessel on the lunar surface, and only the third to operate a robotic rover there.

The space agency said Saturday that the lander's descent was normal until 2 kilometers (1.2 miles) from the lunar surface.

The roughly $140 million mission, known as Chandrayaan-2, was intended to study permanently shadowed moon craters that are thought to contain water deposits that were confirmed by the Chandrayaan-1 mission in 2008.

The latest mission lifted off on July 22 from the Satish Dhawan space center in Sriharikota, an island off the coast of the southern Indian state of Andhra Pradesh.

After its launch, Chandrayaan-2 spent several weeks making its way toward the moon, ultimately entering lunar orbit on Aug. 20.

The Vikram lander separated from the mission's orbiter on Sept. 2 and began a series of braking maneuvers to lower its orbit and ready itself for landing.

Only three nations—the United States, the former Soviet Union and China—have landed a spacecraft on the moon.

For me, it all goes back to that pic of the cleanroom. The dudes building the probe are clearly wearing the jeans and shoes they came to work in. And to construct a spacecraft with one's beard hanging out is just downright unprofessional. It reflects a slapdash mentality which can only result in twisted metal and a fresh crater.

So do they even know what went wrong? If they do I haven't heard of it.

You're actually correct
Jeans and beards, socks and slippers in a clean room
Is not a clean room!

@Reckon &co.

The same dirty room produced world's first successful Mars mission in its first attempt by any country on earth.
The same dirty room produced the first successful Lunar mission in the very first attempt.

NASA's clean room produced first 12 failed missions to the Moon before succeeding in the 13th. NASA's clean room produced very first failed mission to the Mars before succeeding in the 2nd.

Who is cleaner? The statistical data are telling otherwise.

Does the American government even know why gun violence exists in America? Why US is world's number 1 country in mass killings of innocent people by gun violence alone? I haven't heard of any solutions being taken.

Sep 08, 2019
The most important thing here is to learn how it screwed up so it doesn't happen again.

You just got blocked again for being a nationlist troll. I have no time for such people. Obviously you don't have the information I'm looking for. Get over it.

Sep 08, 2019
In all honesty, I think it was a pretty signal achievement even if it did crash. Getting a probe to the Moon for a hundred million bucks was a real eye-opener; a lot of people are going to be watching what India does next.

Sep 08, 2019
Hmmm I wonder which of those Indians in the pictures are "Untouchables". Perhaps they are hoping to have all of their "Untouchables"eventually sent to the Moon to colonise it just to be rid of them.

@guptm
Gun violence in America is as anywhere else in the world. It is the criminally-minded who choose to use guns to kill and injure humans because that is the kind of humans that they are.
It isn't LEGAL gun owners who go around shooting innocent people. But it is the LEGAL gun owners who only wish to protect themselves and family FROM the criminals who want to harm them. You have to learn to separate the two sides - LEGAL GUN OWNERS on one side, and CRIMINALLY MINDED on the other side. And don't forget - it isn't guns that kill people, it is people who kill people. If someone has the intention of killing or injuring, they can use a knife, machete, screwdriver, spanner, hammer AND a car to kill people.

gun violence? really? have you looked at the data? 330,000,000 inhabitants, 8000 die by shootings of all types minus suicide (which is supported by the left) and including cops doing their jobs.
50,000 die by opioid overdose.
35,000 die by auto accident.

More people are killed by hammers than by "assault rifles".

You people are absolute maroons. carry on.

Sep 08, 2019
@DS. You seem to of the attitude that you and America can only think and do the best. Others can't figure out their mistakes. This very thinking makes people like you and Americans the country of low (or perhaps non-existent) moral values. Similarly, you have blocked the entire world. Ego kills!

Sep 09, 2019
you seem
to you
to of the attitude...


Uh huh. Sure looks that way from over here.

You seem to of the attitude that any criticism is leveled at you personally.

That's not a very bright attitude to of.

Sep 09, 2019
The people (like me, for example) who you are abusing are your most likely allies.

But I'm not going to deal with a troll.

Go away. Go make up some fairy tales about how there's no global warming or no such thing as black holes or something.

Sep 09, 2019
Sounds like I have hit the right chord. DS, do you block your neighbors, colleagues, friends in the same way who do not match with your mentality?

You seem to be an egoist, self-centric human not willing to accept others abilities that can parallel or even go beyond yours. Your type of people are a threat for society, who blocks everyone who doesn't follow you.

Good luck to you, DS. Being positive alone is not sufficient, you need to be inclusive.

@SEU. Apparently, there are too many people with weird opinions. Is it the same way, white people of Europe turned America into a dump land of the black criminals of Europe?

SEU, have some sense in your statement. I am stunned that you said it and such people still exist on the planet who think of getting rid of a particular type of people. How can you be a physicist with such a crooked mind? Are you thinking of getting rid of black people out of America?

Shame on you, SEU!

Sep 09, 2019
Similar to the Beresheet failure, and I think the landing thrusters may have shut off because the lander thought it was closer to the surface than it really was. I suspect a radio reflective plasma boundary layer above the surface that the radar thought was the real surface. The lunar atmosphere still has a lot of unknowns as far as electricity/plasma/ dust conditions go.

I watched the Vikram descent live. At 2.1 km, the vertical speed was about 170 kmph. I immediately suspected, something is wrong. The vertical speed should have been around 10 kmph at that height.

Apparently, the rough breaking phase was complete and attitude control was initiated at 2.1 km. This could be an incorrect algorithm. It is like suddenly turning an airplane at 90 degrees to the right just before landing.

Failure Assessment Committee (FAC) is investigating it right now, we need to wait.

I suggest that you read my comment again to understand it better. I did not advocate getting rid of anyone. I was referring to the higher caste people of India who are bigoted against the Untouchables. Surely you must be aware of how the Untouchables are beaten, vilified and mistreated by the higher caste Indians. It is an ongoing problem in India, where the higher caste believe that they are better than the Untouchables, although they are human also. You need to be better informed.


Sep 09, 2019
So after all that horseshit, you have some information?

What a fuckin' luser.

You're part of the problem, not part of the solution. I've worked with a lot of Indians smarter than you.

Lay off the hooch, Schneib. You're not making any sense as usual. You have been REPORTED for using foul and inappropriate language in a science site where children may come in to read the article.

Why is it we get so many rightwingnuts here? Now we have an Indian rightwingnut. This is pitiful.

Racism is disgusting.

Sep 09, 2019
Thanks for confirming you're in favor of racism, @guptm.

I wouldn't expect anything different from someone who thinks lower castes should be killed.

Sep 09, 2019
They'll choke you off for too many downvotes. Have you found out how many yet?

What a disgusting racist.

Sep 09, 2019
It's amusing to poke a racist until they puke.

This Landers, Landed

If this is true
170km/h at 2.1km
105mph at 1.3miles
For
That is 47.2m/s
Or 44.5seconds
This means
This Lander, Landed - or in common parlance, this landers toast

Before this Lander landed
Before this Lander was toast
What was its velocity before impact?
One second before impact

For presumably
This Landers, inertial accelerators
Were intact, measuring this Landers velocity, one second before impact

Fore its actual impact velocity, surely must be known?

Sep 09, 2019
Bummer that it crashed. At least they still have the orbiter.
Hope they try again in the future.

Yorkshire:
Where these natives call a spade a spade
Fore on these wild windswept hills of these Bronte moors
You have to be of sterner stuff to survive this Yorkshire climate
For there are now
In these Yorkshire hills
Native Indians, struggling against these windswept, rain soaked, freezing moors
Cursing this Yorkshire weather, in these ancient Yorkshire accents
For these Indians, have become native Yorkshire folk

So guptm, Crumbs in Your Beard Is not a clean room!

@guptm
I have said that: First look at problems in India where a certain class of Indians are considered to be the lowest-of-the-low.

untouchable | ˌənˈtəCHəb(ə)l |
adjective
2 of or belonging to the lowest-caste Hindu group or the people outside the caste system.
noun
a member of the lowest-caste Hindu group or a person outside the caste system. Contact with untouchables is traditionally held to defile members of higher castes.

'A member of the Untouchable caste of India was murdered by a man who was paid to do the killing by the father of the young woman who married the Untouchable. The couple had a child after two years being married. But the father of the young woman was so enraged that she had married an Untouchable that he paid to have the young man murdered as a matter of pride and respect for his family. This happened fairly recently and is an ongoing problem amongst Indians of different castes. Bigotry is alive and well in India.'


Sep 09, 2019
@guptm
If YOU are one of the Untouchables of India, then you must know the pain and horror that your own people have endured, and still are enduring. If you are, then surely you must have a desire to change that tradition and make the Untouchables whole. They are just as human as the so-called 'higher caste' and should be treated well and with respect, rather than as animals. It has nothing to do with colour or religion or politics. Your nation lacks fundamental Egalitarianism - the equality of all persons.

Sep 09, 2019
I'm certain that the scientists in India will want to try to land on the Moon again. Now, it's more a matter of national pride.

Sep 09, 2019
Does this mean, we have the caste system in the clean room?

SEU> member of the lowest-caste Hindu group or a person outside the caste system. Contact with untouchables is traditionally held to defile members of higher castes

SEU
Guptm has already defended the scruffy, clean room
The mind boggles
These space agency clean rooms are as clean as operating theatres
If guptm, thinks this is an example of a clean room
And then SEU
This caste system in all clean room, creates some interesting situations

Sep 09, 2019
The NASA clean rooms are exemplary and outstanding examples of what a clean room should be. In the early to mid 1960s there were pictures of personnel wearing their street clothes without the required hair nets and shoe covers. One picture showed one man sitting with the top of the crack of his bum in full view - which was terribly funny, had it not been a good example of an unclean situation. Dust, soil, and other contaminants have to be kept out of clean rooms, such as the one in which the James Webb space telescope is being prepared. Carelessness is not an option when you're building billions of dollars worth of machinery.
