Spacewalks

Overview

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

Features

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 space walks over time

Pre-requisites

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

Installation instructions

Clone the Spacewalk repository to your local machine using Git. You can install all dependecies by running the following commands:

python3 -m pip install -r src/requirements.txt

To ensure everything is working correctly you can run the test suite using pytest:

python3 -m pytest tests

Usage example

You can run the analysis in the eva_data_analysis.py file via the command line using the following syntax: The following example can be run from the root of this repository:

python3 src/eva_data_analysis data/raw/eva_data.json data/processed/eva_data.csv

The first argument is the path to the JSON input file. The second argument is the path to the CSV output file.
