#### Timeline

The competition is over.

The data for this competition can be downloaded as a compressed zip file.

## Contents

The following file is contained in the zip:

• debris.csv: This is the Input file. It contains the osculating Keplerian elements of the debris at some reference epoch.

Additional files are also included in the zip and their purpose explained on the submission format page.

• example_submission1.txt: contains a mission that passes the preliminary validation (with DSM)
• example_submission2.txt: contains a mission that passes the preliminary validation (no DSM)
• TRIAL-my_mission.txt: this is the same as example_submission1.txt, but the file name is such that, if submitted, it will only trigger the preliminary validation and not the scoring step (i.e. it will not be added to the leaderboard)

### Input File

The input file is a CSV file. After a one line header, each row/line in the file represents a particular debris piece described by its id, the reference epoch [MJD2000] and its osculating Keplerian elements: $$a,e,i,\Omega, \omega, M$$ all in SI units. The position and velocity of each orbital debris at any epoch may then be determined following the equations given in the equations page.
