00:00 After the rough breaking and the attitude hold phase, we shall be having the fine breaking phase,

00:05 which will continue for nearly 3 minutes.

00:10 The hold phase is being driven by the autonomous landing sequencer and there is no intervention from ground.

00:21 Yes, Arushi, you can see on your screen that the current altitude is about 10 km from the moon.

00:34 Yes, our Prime Minister, Mr. Narendra Modi has joined Johannesburg, South Africa to encourage us all.

00:54 Yes, we are privileged to have with us Honorable Prime Minister of India,

01:14 Mr. Narendra Modi, who has joined us from South Africa's Johannesburg to encourage us.

01:24 Yes, you can see that the attitude hold phase has been easily passed by the lander phase

01:35 and the fine breaking has begun.

01:39 Now we can see that the height of the lander is about 5.6 km, which will be about 800 m above the phase.

01:53 We can hear from the mission operations team that the sensors are performing nominally

02:05 and we are currently in the midst of the fine breaking phase, which is going to continue for 3 minutes

02:12 and the altitude is going to be reduced to nearly 800 m at the end of this phase.

02:19 Yes, as Arushi said, after 3 minutes the height of the lander will be about 800 m vertically

02:29 and the horizontal velocity, vertical velocity and even downrange of the lander will be about 0.

02:38 We can see the visual of the lander module and we can see that the downrange travelled is nearly 831 km.

03:02 Yes, you can see on your screen that the height of the lander has reduced to 3 km above the moon surface.

03:15 We are very close to the moon surface, nearly 2.6 km as we can see.

03:44 Yes, you can see that the height of the lander is about 1 km.

03:54 We are nearing the final phase of the power descent, which is going to be the vertical descent phase

04:12 or the local navigation phase.

04:14 Yes, we are very close to the final phase of the power descent.

04:23 You can hear the applause that we have successfully completed the third phase of the power descent.

04:32 We have now come to the vertical descent phase, which has started off very well.

04:44 Lot of applause indicates that till now the performance has been nominal.

04:51 We are in the vertical descent phase 1.

04:57 The altitude is being brought down from 800 m and we are nearing and approaching the lunar surface.

05:07 Yes, you can see on your screen that the height of the lander is decreasing.

05:16 We are just above the landing site and the height is about 600 m.

05:23 During this phase, after reaching the height of about 150 m, the lander will hover again for about 20 to 22 seconds.

05:35 We are above the landing site.

05:40 The horizontal as well as the vertical velocity is now being constantly reduced

05:47 and the lander module has begun its descent towards the landing site.

05:53 Yes, you can see on your screen that the path has been decided and the lander is following it.

06:13 At this time, we have come down to about 200 m.

06:18 Now we can see that we are at an altitude of about 150 m from the lunar surface.

06:32 Yes, you can hear the applause which is being done by all these scientists after the completion of the second hybrid phase.

06:59 Yes, if you look carefully, the altitude is decreasing again.

07:09 Now we are at an altitude of about 135 m.

07:14 The sensors that are updating at this point are providing confirmation of the safety of the landing site.

07:32 Now you can see that the height of the lander is about 65 m.

07:46 Currently only two engines are now being fired and we are nearly at zero velocity, vertical and horizontal.

07:56 We were hovering and now we are approaching the moon surface.

08:02 Slowly the speed of the lander is being reduced and we have now come down to about 50 m.

08:15 We can see the Honorable Prime Minister, Shri Narendra Modi ji, who is here to encourage us

08:22 and he is critically looking at the visuals.

08:45 People are applauding. Let us all wait to hear from the Secretary Department of Space and Chairman ISRO, Shri S Somnath.

08:57 The lander module has landed safely and softly on the moon surface.

09:04 This is a matter of great pride for us.

09:07 There is a saying in Hindi, "Chanda Mama Door Ke" but now we can say, "Chanda Mama Apne Ghar Ke".

09:15 Very good. The hard work of the entire ISRO community has come to fruition.

09:21 Honorable Prime Minister, greetings.

09:40 Sir, we have achieved soft landing on the moon. India is on the moon.

09:46 the moon. [Applause]
