Perhaps many this year watched live on an attempt to land the first Israeli probe on the moon.

Tracking this was quite convenient, since telemetry data on the speed and position of the station above the moon were often displayed in the broadcast.

The total volume of telemetry shown is such that, on the whole, it was possible to evaluate many nuances related both to the design of the station and to the peculiarities of its landing. This is really interesting. The fact is that landing on the moon is a very difficult process, the nuances of which are rarely published. In particular, real telemetry is usually not published at all.

Here, if you look at the published data, you can get the station’s height above the Moon, horizontal and vertical speeds, axial accelerations and the mass of the remainder of the fuel with an oxidizer with a time reference. All these data allow not only to evaluate the station landing pattern, but also to determine which sensors correctly reflected the reality. Since all parameters must be related to each other.

It is only necessary to pull them out of the broadcast and bring them into one table. The only thing holding back was the need to process a large amount of data. It was hoped that someone would do this work earlier, or SpaceIL would publish the original telemetry and a detailed description of the accident.

Alas, no one created the table, and a detailed description of the accident did not appear. As far as I know, it was only released a message that the shutdown of the main engine was triggered by the command sent by the dispatchers to the probe to restart one of the measuring sensors.

Personally, this information was not enough for me. In the end, all the same, I made a tablet in Excel.
