Spacewalks is a Python analysis tool for researchers to generate visualisations and statistical summaries of NASA's extravehicular activity datasets.

Key features of Spacewalks:

• Generates a CSV table of summary statistics of extravehicular activity crew sizes.
• Generates a line plot to show the cumulative duration of spacewalks over time.

Spacewalks was developed using Python version 3.12

To install and run Spacewalks you will need have Python >=3.12 installed. You will also need the following libraries (minimum versions in brackets)

• NumPy >=2.0.0 - Spacewalk's test suite uses NumPy's statistical functions
• Matplotlib >=3.0.0 - Spacewalks uses Matplotlib to make plots
• pytest >=8.2.0 - Spacewalks uses pytest for testing
• pandas >= 2.2.0 - Spacewalks uses pandas for data frame manipulation

You can install all required modules using this command from the root directory of the repository:

python3 -m pip install -r requirements.txt

unset PYTHONPATH PYTHONSTARTUP
python3 -m venv ./venv_spacewalks
python3 -m pip install -r requirements.txt

Before running the main script or testing script, make sure to activate the created virtual environment:

• On GNU/Linux:

source ./venv_spacewalks/bin/activate

• On Windows:

source ./venv_spacewalks/Scripts/activate

To regenerate the results and figures, run eva_data_analysis.py using python3:

python3 eva_data_analysis.py

To specify the input JSON (INFILE) and output CSV file (OUTFILE):

python3 eva_data_analysis.py INFILE OUTFILE

To run all unit tests:

python3 -m pytest --cov --cov-report=html

1. Install howfairis.

2. Then run:
