The White House Office of Science and Technology Policy (OSTP) declared 2023 as the Year of Open Science.  NASA, along with 10 other Research and Development federal agencies and 88 Academic institutions under the HELIOS umbrella, celebrate this opportunity to advance the adoption of open, equitable, and secure science through open science policies and practices.

NASA's Earth Science Data Systems (ESDS) Program requires that all software developed through research and technology awards (i.e., Research Opportunities in Earth and Space Science [ROSES] or unsolicited proposals) or other government-funded development is to be made available to the public as Open Source Software (OSS). This includes all software developed with ESDS funding used in the production of data products, as well as software developed to discover, access, analyze, visualize, and transform NASA data. This policy does not apply to commercial off-the-shelf software.
