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 …

How did you calculate the 'landed' speed of 110 miles/hour from Line of Sight Velocity?
That’s the fuzzing in “more than.” We don’t know the speed perpendicular to the line of sight. But more likely than not, that would be a factor of 2, not 10 or 100.
