The data for this competition can be downloaded as a compressed zip file.
The ESA Data Analytics Team for Operations has prepared the data with care. If you have any questions after reading this description please feel free to post on the slack channel.

The training set (train_set/) is composed of context and electric current measurements data for the following four Martian years:
The test set (test_set/) is composed of context data only for the following fifth Martian year:
A Martian year is defined by 687 earth days which is not respected by smaller sets D and E. Note that space communication issues may have introduced gaps in the given data.
Context files are all in CSV format and are using the following nomenclature:
The following list describes the columns of each of these CSV file types:
SAAF files: Solar aspect angles are expressed with respect to the Sun-MarsExpress line.
The angles are a good information about how much power from the solar panels the spacecraft is going to get (sa) and how much each of its faces is roasting to the sun or freezing in its own shadow (sx, sy, sz).
DMOP files: Detailed Mission Operations Plan files.
The DMOP files show when the different subsystems' commands have been triggered. Each subsystem command string include the subsystem name along with the command name. Each subsystem command name can be considered as a signature. Due to the amount of different commands, they won't be explained here. These commands have different effects on temperatures of the different subsystems of the spacecraft thus impacting in different ways the thermal subsystem's reactions. In these commands you may find the ON/OFF of radio communications, the ON/OFF of the science instruments, etc.
FTL files: listing of spacecraft pointing events (Flight Dynamics TimeLine).
The events listed here are pointing and action commands that can impact the attitude of the satellite, thus they also may impact the solar aspect angles of the orbiter and/or the switch ON/OFF of some instrumentation.
EVTF files: more events are listed in these event files.
This file contains a lot of events. It covers parts of the flight dynamics timeline present in the FTL and complements information with a lot of other events. In this file you can find the following eclipse events;
*_UMBRA_END which indicates the start and end time of different phases of the eclipse (penumbra/umbra)
Some of the descriptions are self-explanatory while others are not. Due to the amount of different events, they won't be explained here. Nevertheless, the descriptions can be used as signatures of events, similar to the subsystem commands in the DMOP files.
LTDATA files: long term data including sun-mars distance and solar constant on Mars.
Observation files are also in CSV format and follow the nomenclature:
These files are present only in the training set (train_set/) as they contain the measured electric current of 33 thermal power lines. Each file contains 34 columns:
Usually one observation is made every 30 seconds or 60 seconds. The goal of the competition is to predict the average electric current per hour.
