Re: Chandrayaan 3: Launch and Discussions
Last few seconds DD switched to some close up shot and we could not see real time Hv, Vv and Alt data. Hope DD does a better job when we see the next landings on Mars and Venus.

Jai Hind.
Now to get to the serious Science stuff and stake our territorial rights on the moon.
Hoping in the same breath that we will also stake our territorial rights on the chanda to our west soon

Re: Chandrayaan 3: Launch and Discussions
Horizontal was quite low 0.002 m/s or something, vertical was a bit more I think, even then 3 m/s is around 7 mph not even a fender bender!
Re: Chandrayaan 3: Launch and Discussions
^^^ The velocity value kept changing up and down, and the camera was not pointed at the screen, so we dont know for the exact moment.
However, the important thing is that hover was achieved several 100 meters above the lunar surface, which means that the craft was under full control and behaving normally. So I am pretty sure the landing speed was within parameters per mission.
3 m/s is the upper limit of the design and becomes borderline. Mission parameters would have called for a much lower value as optimal landing velocity.

Re: Chandrayaan 3: Launch and Discussions
Congratulations!!!!
India broke the sixth country syndrome.
First country to land near South Pole of the moon.
President Kalam wrote he wanted to break the 'sixth' country syndrome. Every achievement has the blurb. "India is the sixth country to do this, blah, blah..."

Re: Chandrayaan 3: Launch and Discussions
Agree Ramana ji, India should also get out the "shoe string budget" mindset to forever bury the sixth country syndrome. Big achievements need and deserve big budgets.
Re: Chandrayaan 3: Launch and Discussions
when can we expect post landing images from the lander cameras?
Re: Chandrayaan 3: Launch and Discussions
When does the rover get deployed?
Re: Chandrayaan 3: Launch and Discussions
Happy for the Safe Landing.
Late because was on a panel discussion about landing.
Great achievement for India.
Want to see the Rover sliding dow the ramp, saying ... Mai aya hoon!!!

Re: Chandrayaan 3: Launch and Discussions
time to revisit the landing video and savour again and again and again...
Re: Chandrayaan 3: Launch and Discussions
We need a picture of the Indian flag on the dark side of the moon .. oh how that picture would sell !!
Re: Chandrayaan 3: Launch and Discussions
Awesome !
Waiting for the Next Sequential Steps in Progress, such as Pargyaan sliding down, roving, doing the tests and Vikram doing its own.
It would also be great if the two can survive the Lunar night and come back roaring after that.
The whole launch all the way to the landing has been extremely precise as shown by the PM being left with a lot of fuel and the copybook soft landing.

Re: Chandrayaan 3: Launch and Discussions
The last visuals from ISRO official @59.27 minute mark reads this - (all within tolerance limit) -
Height/Altitude left to be covered - 19 Meters, Vertical velocity = 1.584 m/s and horizontal velocity = .225 m/s
After that it simply landed.

Re: Chandrayaan 3: Launch and Discussions
Yes, That was confusing.
Re: Chandrayaan 3: Launch and Discussions
mission parameter's upper limit on landing speed was 3 m/s meaning it would survive.
Optimal value for landing speed would be much lower....not published.

ISRO chairman Somanath speaking to the press at the moment on DD live.
Re: Chandrayaan 3: Launch and Discussions
Bangladesh gave wide coverage of the moon landing. How are the other neighbors reacting?
Re: Chandrayaan 3: Launch and Discussions
Congrats to ISRO, BRF, SSSalvi, Amber G., and others I don't remember. And, most importantly, Dilbuji just for showing up in the nick of time
Now, is there a thread that has all the rona dhona from the usual suspects (liberals, p@kis, Bri$hits, western media etc)? Wish to enjoy that with a topping of schadenfreude

Re: Chandrayaan 3: Launch and Discussions
2 m/s or lower was deemed very safe for CY3.
For CY2, this value was equal to or lesser than 1 m/s, as far as I can recall.
Re: Chandrayaan 3: Launch and Discussions
Congratulations ISRO and to the Nation.
Re: Chandrayaan 3: Launch and Discussions
When will DD learn to focus on important things while covering such events. Sigh.
Re: Chandrayaan 3: Launch and Discussions
Waiting for more images and videos to come out... Hope ISRO posts the soft landing video, with lunar dust flying off. That would be cool on another level.
Re: Chandrayaan 3: Launch and Discussions
also the feed from landing camera was missing at touch down moments.

Re: Chandrayaan 3: Launch and Discussions
Congratulations to ISRO. Jai Hind. Very proud moment to be first to land on South Pole of moon.
Re: Chandrayaan 3: Launch and Discussions
any basic post landing status updates ?
like:
-orientation, power generation from solar panels?
-ground tilt angle if any ?

Jai Hind! Bharat Mata ki Jai! Congratulations ISRO! Congratulations to the Nation!
I think the live video feed will be uploaded through the Deep Space network and will be made available soon. I don't recall if it was going to be a live video feed of the landing but there were time-lapsed pictures being beamed back where you could see the smooth landing zone just below the lander as it descended and went into hover mode.

Dilbu you rock! Thank you.

Re: Chandrayaan 3: Launch and Discussions
The real work for the ISRO engineers is just beginning. They are checking parameters on the rover to see if it survived the landing well and powering up its systems and checking system parameters. Rover will be working for the 14 days and nights and preparations for that are probably underway. If PRagyaan goes through this entire timeframe without a hitch, then a ton of pictures and scientific data will come our way.
BIggest thing they are probably looking at pictures in front of the lander Vikram and whether it has clear space to roll out a ramp so PRagyaan can come out smoothly. (My speculation: if this is not possible and there is boulder in front of Vikram, the 'hop' of the lander that people were speculating about might come sooner, but this is pure speculation).

Small step for India giant leap for South Asia.
Re: Chandrayaan 3: Launch and Discussions
The decision on when to deploy the rover will be taken today:
