Frequently Asked Questions

NASA's Open Data Catalog is constantly growing as more and more of NASA's published and raw data are added. Poring through thousands of datasets is no small task--let us guide you to find the data you need. Below, check out some of the common questions we frequently answer about this catalog.
Q: How do I find all of NASA's open datasets related to Mars?
A: On the homepage of the Open Data Portal, type any search terms you want into the search bar below the welcome message. You can also click the magnifying glass in the top right of the header to expand a search box. On the Data Catalog page, type into the search bar at the top of the page. Narrow your search results by category, data type, or tags/keywords by clicking the filters in the left hand margin.
Q: I found the dataset I need, but what fun things can I do with it?
A: For tabular datasets, you'll see a "View Data" link near the top of the dataset page. Click this link to view the data in its tabular form. Then click "Visualize" to play with different ways of displaying the data. Want to see how the data have changed over time, expand the "Calendar" menu. To display the data on a map, expand the "Map" menu. To view the data in an interactive series of custom charts and graphs, try playing with the "Data Lens" feature.
Q: I found the dataset I need, but how do I cite a NASA dataset in a paper?
A: Take a look at the dataset itself to see if any guidance is offered for citing the data. Published papers will often include a citation to use as a reference. You can also contact the dataset owner, listed on every dataset page, for guidance.
Q: I found this really cool NASA dataset somewhere else--but it isn't in the catalog. How do I request to have it added?
A: You can make a suggestion for an addition to the open data catalog using our dataset nomination page.
Q: How do I find out more about NASA's open source code?
