:00:00. > :00:00.with all the latest releases in the Film Review, but first it's
:00:00. > :00:41.Get ready, your Indian experience starts now.
:00:42. > :00:45.As soon as you step off the plane, India hits you like a big,
:00:46. > :00:51.It is everything you've ever imagined it to be.
:00:52. > :01:00.The first thing you'll notice will be the traffic.
:01:01. > :01:14.For 70 years this country has been independent of British rule
:01:15. > :01:18.and the cities that have sprung up around the old colonial grandeur
:01:19. > :01:21.seem chaotic, but they do kinda work.
:01:22. > :01:29.And India has found a niche in the wider world.
:01:30. > :01:34.Half of its 1.2 billion people are aged 35 or under.
:01:35. > :01:36.Maybe that's why it's known for its IT know-how,
:01:37. > :01:42.And the bosses of some of the biggest tech companies
:01:43. > :01:48.But it hasn't had as much luck in taking over the world
:01:49. > :01:55.After all, how many Indian tech brands can you name?
:01:56. > :01:58.The truth is that although there is a middle class of consumers
:01:59. > :02:01.here willing to buy brands, it's not actually that big
:02:02. > :02:06.We're here to find out how India is preparing for its future and,
:02:07. > :02:13.let me tell you, it is reaching for the stars.
:02:14. > :02:23.In 2013, India became the fourth spacefaring nation to launch a probe
:02:24. > :02:27.into orbit around Mars and, unlike those who came before them,
:02:28. > :02:37.The Indian Space Research Organisation, Isro, has been gaining
:02:38. > :02:40.a reputation for doing tons of successful space stuff
:02:41. > :02:53.Their Mars mission came in at just $74 million,
:02:54. > :02:55.that's less than it cost to make the film Gravity.
:02:56. > :02:58.And, in February this year, they made history again by launching
:02:59. > :03:01.a record 104 satellites on a single rocket.
:03:02. > :03:04.It could just be that India has created the perfect combination
:03:05. > :03:06.of big brains with big space experience, but a mentality
:03:07. > :03:16.Just the sort of place you might go if you wanted to,
:03:17. > :03:19.say, land a robot on the moon for the space equivalent
:03:20. > :03:24.How confident are you that this will work?
:03:25. > :03:31.Welcome to the earthbound HQ of Team Indus, one of a handful
:03:32. > :03:33.of start-ups competing for the Google Lunar XPRIZE,
:03:34. > :03:36.that's $20 million for the first commercial company to land a rover
:03:37. > :03:52.The Team Indus space craft goes into two days of Earth orbit
:03:53. > :03:54.and then, boom, 4.5 days to the moon.
:03:55. > :03:57.12 days of spiralling down to the surface and then if all goes
:03:58. > :04:00.well, out comes the rover, travels half a kilometre,
:04:01. > :04:02.sends back HD video and wins the prize.
:04:03. > :04:12.Rahul Narayan is the co-founder of Team Indus and has been
:04:13. > :04:16.here since the very start of the project, way back in 2010.
:04:17. > :04:24.At that point you had no idea how you would acheive it?
:04:25. > :04:27.Yes, I googled it and figured out what Wikipedia had to say
:04:28. > :04:32.You did an internet search on how to land on the moon?
:04:33. > :04:36.Did it have any useful information?
:04:37. > :04:46.It said there had been 85 attempts and I think every second attempt
:04:47. > :04:50.Six years later, there are around 100 people working very hard here,
:04:51. > :04:53.and it certainly looks like they know their space stuff.
:04:54. > :05:01.Even the toilets are appropriately labelled.
:05:02. > :05:06.And they've built themselves all the things that a serious space
:05:07. > :05:08.company should have, like a mission control room,
:05:09. > :05:11.a model lander that makes smoke, and a simulated lunar surface
:05:12. > :05:19.So what do you use to simulate moon dust?
:05:20. > :05:21.Just like national space agencies, testing every component
:05:22. > :05:24.and simulating every stage of the mission is a huge part
:05:25. > :05:27.We're making sure we do everything right.
:05:28. > :05:32.We are going to make it frugal, specific to the mission,
:05:33. > :05:34.but there's absolutely no corners that we're cutting.
:05:35. > :05:38.And, to look at it from a more philosophical way, we have one shot
:05:39. > :05:43.We don't have a flight spare, so if one blows up we can go and fly
:05:44. > :05:45.the other, we have to get this right.
:05:46. > :05:49.Team Indus is one of five start-ups from around the world who have
:05:50. > :05:50.secured launch contracts for their rovers.
:05:51. > :05:53.While they can't say for sure, they think they'll launch before
:05:54. > :05:57.any other team, and so perhaps be the first team to land and win!
:05:58. > :06:01.That's except for the fact that to save costs they have had to sell
:06:02. > :06:04.some of their spare launch weight to a competitor rover.
:06:05. > :06:08.Japan's Team Hakuto will be onboard too.
:06:09. > :06:11.You're both going to get to the moon at the same time.
:06:12. > :06:13.Yes. How is that going to work?
:06:14. > :06:16.It's whoever touches down first and whoever has the fastest rover?
:06:17. > :06:22.It's going to be crazy! In a manner of speaking, yes.
:06:23. > :06:27.So it's a race, it's going to be a very interesting race,
:06:28. > :06:30.and once we touch down and both the rovers are deployed,
:06:31. > :06:34.let's see which one makes 500m first.
:06:35. > :06:41.All of that assumes of course that the rovers make it
:06:42. > :06:46.Space exploration is a risky business and when it goes wrong,
:06:47. > :06:53.Six years, hundreds of thousands of hours of effort and millions
:06:54. > :07:00.spent, and there's certainly a lot riding on getting things right.
:07:01. > :07:03.You mitigate the big pieces and then you start mitigating the smaller
:07:04. > :07:07.risks and at the end of the day, absolutely, one small wrong piece
:07:08. > :07:09.of code that somehow made it through could kill
:07:10. > :07:16.There is a word here in India that I think describes Team Indus's
:07:17. > :07:28.I've come to the centre of Mumbai, to Dharavi -
:07:29. > :07:38.Here, in its tiny alleyways, "jugaad" is all around,
:07:39. > :07:40.as a desperately poor population reuses as much
:07:41. > :07:51.Built by workers who flocked to the city over hundreds of years,
:07:52. > :08:06.some of the houses here date back to the 1840s.
:08:07. > :08:09.Up ahead, there is a pile of shredded denim which they use
:08:10. > :08:14.They burn it to fuel the kilns, just like they burn a lot of stuff
:08:15. > :08:19.You can really tell the air quality is very poor.
:08:20. > :08:23.You just have to take a few lungfuls and it starts to burn the back
:08:24. > :08:26.of your throat, it makes your eyes sting.
:08:27. > :08:29.The smoke is a necessary evil for the people of Dharavi.
:08:30. > :08:32.Like most of the developing world, pollution has been the price India
:08:33. > :08:38.The smog that gives Mumbai its spectacular sunsets has also
:08:39. > :08:41.made it the fifth most polluted mega city in the world.
:08:42. > :08:44.And when the sun disappears before it hits the horizon,
:08:45. > :08:48.In November, 2016, the Indian government declared the air
:08:49. > :08:50.pollution in Delhi a national emergency, with harmful pollutants
:08:51. > :09:02.And it's not just caused by all that traffic.
:09:03. > :09:09.I was surprised to find out a lot of it comes from diesel generators.
:09:10. > :09:12.See, the electricity in India isn't very reliable,
:09:13. > :09:15.but there are plenty of businesses that need guaranteed power,
:09:16. > :09:18.so they have their own individual generators that fire up whenever
:09:19. > :09:21.the electricity goes down and that means there are loads of exhaust
:09:22. > :09:24.pipes like this all over the city, which regularly belch out all kinds
:09:25. > :09:42.When you start looking for them, they're everywhere.
:09:43. > :09:45.Here in Bangalore, we've come across a small project to capture
:09:46. > :09:58.So what we have built is a retrofit device that attaches to the exhaust
:09:59. > :10:02.This device can be attached to practically any exhaust pipe,
:10:03. > :10:05.irrespective of what is the age or type of engine you are running,
:10:06. > :10:08.and it captures practically whatever particle matter comes out of it.
:10:09. > :10:11.Once you capture particle matter that is substantially carbon,
:10:12. > :10:13.which is like the basis of everything that exists
:10:14. > :10:16.in the world, at present we recycle it into inks,
:10:17. > :10:18.which we believe is something used by practically everyone
:10:19. > :10:30.The headquarters of Graviky Labs is a mix of art studio and mad
:10:31. > :10:38.laboratory - the perfect combination, if you ask me!
:10:39. > :10:40.Their so-called "air ink" does have a few restrictions.
:10:41. > :10:49.It will only ever come in black, and at the moment it's not good
:10:50. > :10:51.enough quality to be used in printers.
:10:52. > :10:54.Graviky is giving it to artists, who are finding their own
:10:55. > :10:57.Painting and screenprinting, for example, for use
:10:58. > :11:01.And while the ink may only have limited uses at present,
:11:02. > :11:05.Nikhil insists it is still better to put the carbon to good use rather
:11:06. > :11:10.There are many technologies that have captured pollution in one way
:11:11. > :11:13.or the other, they are all so supposed to do that,
:11:14. > :11:16.but if you don't recycle it you are actually leaving it
:11:17. > :11:36.I'm afraid that's all we have time for in the shortcut of Click, the
:11:37. > :11:39.full-length version is for you on iPlayer to watch right now and
:11:40. > :11:44.there's loads of extra photos from our trip to India on Twitter
:11:45. > :11:46.@BBCclick. Thanks for watching and we'll see you soon.
