Reusability counts!

rocket-cores

Rocket cores is a simple tool to fetch most reused first stage cores and calculate total carried mass to the orbit for each core. It leverages spaceX graphQL Api: https://api.spacex.land/graphql/

Installation & Usage:

Installation via pip: rocket-cores uses poetry as a build tool. To use rocket-core, simply type (inside rocket-cores dir):

poetry install
poetry build

To run rocket-cores, just type:

poetry run rocket-cores --cores 5

Command will fetch the api asynchronously for 5 most reused cores. If you call rocket-cores without "--cores" it will fetch all cores data by 10 cores (pagination is used - additionally you need to wait 10 sec for next page, because of the API limits)

poetry run rocket-cores --cores 10

Will produce:

The most reused rocket cores:
