Software is the most used instrument in astronomy, and organizations such as NASA and the Heidelberg Institute for Theoretical Physics (HITS) fund, develop, and release research software. NASA, for example, has created sites such as code.nasa.gov and software.nasa.gov to share its software with the world, but how easy is it to see what NASA has? Until recently, searching NASA’s Astrophysics Data System (ADS) for NASA’s astronomy software has not been fruitful; NASA has funded the Astrophysics Source Code Library (ASCL ascl.net) to improve the discoverability of these codes. The ASCL, now celebrating its 20th anniversary, is a free online registry of software used in astronomy research and is indexed by ADS, Web of Science, and other resources. Adding NASA and HITS astronomy research codes to the ASCL with appropriate tags enables finding this software easily not only in the ASCL but also in ADS and other services that index the ASCL. This poster presentation covers the changes the ASCL has made to enable discovery of NASA software in ADS and the results of this work.
