pds3 reads PDS3 files, a standard published by JPL and used throughout NASA space missions. While PDS3 is being supplanted by PDS4, a XML based standard, PDS3 is still being used and is needed for accessing historic data.
pds3 is available from CRAN, so can be simply installed via
install.packages("edgarWebR")To install the development version,
# Install the development version from GitHub:
# install.packages("devtools")
