# NASA Space Sound Archive
# Sound exists in space. Sometimes.
#
# Note that the download URLs in the returned object require soundcloud authentication to access the files.
# This will likely change in the stable version of the API.
#
# Example:
# sounds <- nasaSounds(query = "apollo")
#
# This function defaults to using the NASA DEMO_KEY.
#
# Obtain your own NASA API Key here:
# https://api.nasa.gov/index.html#apply-for-an-api-key
