Access National Aeronautics and Space Administration (NASA) Open APIs for Space and Earth Data.
The nasa package provides functions to access and download data from various NASA APIs, including:
- Astronomy Picture of the Day (APOD): https://api.nasa.gov/planetary/apod
- Mars Rover Photos: https://api.nasa.gov/mars-photos/api/v1/rovers
- Earth Polychromatic Imaging Camera (EPIC): https://api.nasa.gov/EPIC/api/natural
- Near Earth Object Web Service (NeoWs): https://api.nasa.gov/neo/rest/v1/neo/browse
- Earth Observatory Natural Event Tracker (EONET): https://eonet.gsfc.nasa.gov/api/v3/events
- NASA Earthdata Common Metadata Repository (CMR): https://cmr.earthdata.nasa.gov/search/collections.json
All retrieved data is returned in cleaned, tidy data frames suitable for analysis or visualization.
Install from CRAN:
install.packages("noaa")
Install from the rOpenGov universe:
# Enable repository from ropengov
options(repos = c(
ropengov = 'https://ropengov.r-universe.dev',
CRAN = 'https://cloud.r-project.org'))
# Download and install noaa
install.packages("noaa")
Most functions in this package can be run using the default DEMO_KEY. However, because the DEMO_KEY is publicly shared and subject to rate limits, it is recommended to request your own API key from NASA by visiting https://api.nasa.gov/.
get_apod_metadata(start_date, end_date, api_key = "DEMO_KEY", folder_name = NULL)
- Queries APOD to retrieve image metadata between two dates.
- Only returns results where the media type is an image.
- Optionally saves images to a folder on the Desktop.
get_mars_rover_photos_and_metadata(rover, earth_date, api_key = "DEMO_KEY", folder_name = NULL)
- Retrieves photos taken by a Mars rover on a specific Earth date.
- Valid rover names: "curiosity", "opportunity", "spirit", "perseverance".
- Optionally saves photos to a folder on the Desktop.
get_earthdata(keyword, n_results, start_date = NULL, end_date = NULL)
- Searches the NASA Earthdata CMR database for datasets matching a keyword.
- Can optionally filter results by a temporal range.
- Returns a cleaned data frame of dataset metadata.
