The Vikram lander has been found, but the odds that it is in working condition are long. Doppler data indicate it landed at more than 110 miles per hour.https://www.nytimes.com/2019/09/10/science/india-chandrayaan-2-vikram.html …
Yes, which is why I wrote the rest of the article about how spacecraft control systems generally are unable to recover from a major unexpected anomaly during landing. It would be incredible (and wonderful!) if Vikram made it to the surface intact.

More info is needed to draw conclusions. Doppler data is good for change in speed not absolute, certainly as these these levels. So using their conclusion on impact speed IM(expert)O is inaccurate.

Doppler gives you line-of-sight velocity, not just acceleration, correct?
