Vikram lander will fail onlee.

Posted: **07 Sep 2019 02:30**

Modi would not have walked out...if there was a glimmer of good news. No?

Is that Orbiter calling Lander onlee?

Posted: **07 Sep 2019 02:31**

Media just giving unnecessary hopes?

Posted: **07 Sep 2019 02:32**

The time lag for comms is about 2.5 seconds only.
if the lander sped up in the end, instead of further slowing down, they know already.
Attitude control data must have been available till they lost comms, so they will know if it is tipping over.
The animation on the screen generates images based on the lander's attitude control data. It showed a tumble right before comms was lost.

ISRO will release statement soon after reviewing the data....

Posted: **07 Sep 2019 02:32**

Now Republic World claims: "Awaiting data" and "Waiting for signal from Vikram"

Posted: **07 Sep 2019 02:33**

Wasn't the orbiter supposed to fly by and take pictures of the lander?

Re: the hand gestures, my guess is they were debating if it went into a tumble or descended in the correct orientation. Also heard one lady scientist also say that we've lost RF, but doesn't mean that the rest of systems didn't perform.

up to 2.1km altitude normal parfarmance

Posted: **07 Sep 2019 02:34**

Everything good until 2.1 km. Then communication lost.

Posted: **07 Sep 2019 02:34**

comm lander to ground was lost

Posted: **07 Sep 2019 02:34**

Mission normal upto 2.1 kms thereafter comm lost.

Posted: **07 Sep 2019 02:34**

ISRO Chief: Comms lost at 2.1km. Naarmal until then. Data being analyzed.

Posted: **07 Sep 2019 02:34**

2.1 km altitude was the last known normal performance, then comms was lost.
Data being analyzed.

Posted: **07 Sep 2019 02:35**

The communication seems to be working. They are waiting for comms to work. Even if the lander was partially damaged, it would be a success if we get a ping back

Posted: **07 Sep 2019 02:35**

Only communication is lost or has it crashed?

Posted: **07 Sep 2019 02:35**

Rahu/Ketu, yeh tum logan kya kara re!

Posted: **07 Sep 2019 02:35**

What causes loss of communications at 2.1 kilometers altitude?

Perhaps that's when lander started tumbling?

Posted: **07 Sep 2019 02:36**

The screen is fixed with picture of the orbiter, which is now coming into play.

If it tumbles, its antenna won't face the orbiter or the earth.

Posted: **07 Sep 2019 02:36**

Modi patting Dr. Sivan.

Posted: **07 Sep 2019 02:37**

Signal lost at 2.1km altitude. it's mostly a hard landing. Tough luck ISRO. Let's get it right next time. Modi just said courageous.

Posted: **07 Sep 2019 02:37**

PM has left the building.

Edit: my bad. PM talking live now.

Posted: **07 Sep 2019 02:37**

Modi giving some encouraging words.

Posted: **07 Sep 2019 02:37**

Modi to scientists be courageous , so bad news.

Posted: **07 Sep 2019 02:38**

orbiter comms is on

Posted: **07 Sep 2019 02:38**

Modi giving gracious pat on the back to the guys. THAT's a leader!

Posted: **07 Sep 2019 02:38**

Modi...giving pep talk.

Posted: **07 Sep 2019 02:39**

Isn't the dust cloud from impact full of scientific data, esp from South pole/far side?

Posted: **07 Sep 2019 02:39**

There should have been some onboard explosion when trying to switch to two engines. Otherwise, there's no reason for loss of Comms at that altitude. JMT.

Posted: **07 Sep 2019 02:40**

Good words for ISRO from Modiji. Well deserved. Whatever happens we are all proud of you ISRO.

Posted: **07 Sep 2019 02:41**

Maybe it's like my BSNL OTP from IndusIndBank. Takes 20 minutes. Be patient.

Posted: **07 Sep 2019 02:41**

Modiji addressing children. Happy to see that the kids are getting a boost at the end of the day.

Posted: **07 Sep 2019 02:42**

If they were switching down from 4 engines to 2 engines, then one of them didn't switch off in time, and created an imbalance, causing loss of attitude stability most likely
I am speculating only.

Posted: **07 Sep 2019 02:43**

let's wait for the data analysts from ISRO to provide answers

Posted: **07 Sep 2019 02:43**

Modi taking questions from students

Posted: **07 Sep 2019 02:44**

Looked like the lander was descending vertically for quiet some time before it deviated sharply from the nominal trajectory.... looking bad.. looking like a tumble.

Posted: **07 Sep 2019 02:46**

ISRO will do proper cause n effect analysis from available data that's for sure. They will scan and get pictures of landing site from orbiter in few hours.
