## Information

* Mission name : Starlink 6
* Launch date UNIX : 1587583800
* Launch date UTC : 2020-04-22T19:30:00.000Z
* Webcast : [YouTube](https://www.youtube.com/watch?v=wSge0I7pwFI)
* Rocket : Falcon 9
* Site launch : Kennedy Space Center Historic Launch Complex 39A
* Initial Latitude: 28.6050
* Initial Longitude: -80.6026
* Payload mass : 15400kg
* Land success : true
* **Other statistics**
  * \#93 flight of SpaceX
  * Starlink count changed from 360 to 420

**Details :**

This mission will launch the sixth batch of operational Starlink satellites, which are expected to be version 1.0, from SLC-40, Cape Canaveral AFS. It is the seventh Starlink launch overall. The satellites will be delivered to low Earth orbit and will spend a few weeks maneuvering to their operational altitude of 550 km. The booster for this mission is expected to land on OCISLY.

also a pretty cool photo taken during the launch

**Thanks to** [**SpaceX-Api**](https://github.com/r-spacex/SpaceX-API) **for the information of the launch**

## Telemetry

The entiere Telemetry of the launch has been extracted using [SpaceXTelemetry](https://github.com/R4yGM/SpaceXTelemetry) (program that i wrote, private at the moment)

SXT reads data frame by frame and it uses the Optical Character Recognition (OCR) and sometimes this OCR could give wrong results because it isn't perfect, so some numbers are faked a little, you could see the complete telemetry extracted in this csv [file](https://github.com/R4yGM/SpacexDB/blob/master/Starlink%206/telemetry.csv) there is also a json [file](https://raw.githubusercontent.com/R4yGM/SpacexDB/7b696f4c01097f2928444753e749c16541a7ee50/Starlink%206/telemetry.json) but the csv file looks more cool in github and it's easier to read, with all the extracted data i started making comparisons and graphs.

## Predictions

with the extracted data i tried to get more data by doing some math calculations using python

**Atmospheric calculations:**

* pressure in [CSV ](https://spacextelemetry.cf/starlink/starlink-6/api/pressure.csv)also avaible in [json](http://spacextelemetry.cf/starlink/starlink-6/api/pressure.json), returned ,in Pascal
* temperature in [CSV ](https://spacextelemetry.cf/starlink/starlink-6/api/temperature.csv)or [JSON](https://spacextelemetry.cf/starlink/starlink-6/api/temperature.json), returned in Kelvin
* acceleration from the liftoff to the SECO2 phase : 13.958 m/s^2
* density in [CSV ](https://spacextelemetry.cf/starlink/starlink-6/api/density.csv)or [JSON](https://spacextelemetry.cf/starlink/starlink-6/api/density.json), in kg/m^3
