The majority of dataset pages on only hold metadata for each dataset. It is common for the actual data to be held on other NASA archive sites. will have the metadata and links to the data as it exists in those many other locations.

Some datasets on are harvested from other NASA data archives and other datasets only exist on This slideshow created for SpaceApps Hackathon participants explains the wider NASA data universe and has some suggestions for finding NASA data.

If you are a NASA staff or contractor and have a public dataset that you would like to upload or link to through metadata, please contact us to set up an account via your email. After you have an account, you can sign-in via the sign-in button at the top of this page and upload or edit your dataset as the dataset owner. NOTE: If you create an account yourself, you'll be able to see some information but not be able to upload datasets. is the dataset-focused site of NASA's OCIO (Office of the Chief Information Officer) open-innovation program. There are also and for APIs and Code respectively.

More information about all open-innovation sites like and Information about datanauts, a problem that lets the public collaborate with nasa. Information about federal open-data mandates that apply to NASA. and are aggregator sites run by GSA (General Services Administration) that collect open-data and open-code from across all U.S. federal government agencies. and feed into and respectively. has an APIs for working with their datasets that make them worth checking out even if you're strickly interested in NASA data.

Most current programming languages support HTTPS communication or can call on applications that support HTTPS communication. See sample scripts below. We provide support for wget, linux shell script, Perl, and Python. When recursively downloading entire directories of files, wget will likely require the least amount of code to run.

To use these, click "Download source" to download or copy and paste the code into a file with an extension reflecting the programming language (.sh for Shell Script, .pl for Perl, .py for Python). Be sure the Unix execute permissions are set for the file. Lastly, open a terminal or shell and execute the file. Command-line examples are also included below.

Join us in celebrating the 50th anniversary of the Apollo 11 Moon landing and hear about our future plans to go forward to the Moon and on to Mars by tuning in to a special two-hour live NASA Television broadcast at 1 p.m. ET on Friday, July 19. Watch the program at

The most important conditions are: You may copy, modify and redistribute XFOIL or its modifications freely.

The intent is to exchange information on Xfoil and other aero software.

  • Note: The source code for Xfoil itself is the same for Unix and Win32. The plot library directory (plotlib) has a separate win32 subdirectory. See all the README files for more info. Win32 Notes: Interaction with Win32 XFOIL is through a DOS-type text console window. Some of Microsoft's Win32 OS'es (Win95/98/ME) have limitations on # of lines in a console window and cannot fully display XFOIL menus or output. Win95/98/ME also have other shortcomings with regard to resource usage and stability although XFOIL runs under these OS'es.Windows NT, Win2000 and Windows XP are the recommended Win32 platforms. Win32 Exe Notes: The executables for Win32 were compiled using the Intel Fortran Compiler 5.01-15 and Visual C++6.0. The Intel compiler (thanks to Tom Clarkson at Intel) was used to optimize executables for P3 and P4 Pentium architectures. The XFOIL executables should run on any Win32 Pentium-class machine as compiler options were used to include both optimized code and generic Pentium or AMD processor code for portability.

The API provided by the NSIDC DAAC allows you to access data programmatically using specific temporal and spatial filters. The same subsetting, reformatting, and reprojection services available on select data sets through NASA Earthdata Search can also be applied using this API. These options can be requested in a single access command without the need to script against our data directory structure. This API is beneficial for those who frequently download NSIDC DAAC data and are interested in incorporating data access commands into their analysis or visualization code. If you are new to the API, we recommend exploring this service using our Jupyter Notebook. See below for further guidance on the API format and examples of this service.

The Jupyter notebook available on Github allows you to explore the data coverage, size, and customization services available for your data set(s). The notebook will also print the API command that can be used from a command line or browser or within the Notebook itself. No Python experience is necessary; each code cell will prompt you with the information needed to configure your data request. The README includes several options for running the notebook, including via Binder, Conda, and Docker. The Binder button available in the README allows you to easily explore and run the notebook in a shared cloud computing environment without the need to install dependencies on your local machine. If you are interested in using the notebook to bulk download data, we recommend either running this notebook locally using the Conda or Docker options, or using the print API command option if you're running the notebook via Binder. 041b061a72
