The preferred method for others to obtain the software is to send an e-mail to Larry.Kos@nasa.gov. The requester will receive a form to fill out to get the software.
The form requires information regarding the recipient, including contact information and citizenship, government contracting information, and purpose for use. This type of distribution enables the development and maintenance of metrics likely to be of greatest interest to the In-Space Propulsion Program, such as level of demand and areas of application of the software.
Note for both above:
Any governmental agency or anyone who is working under a government contract that requires the software can use it royalty free.
