Innovators at NASA's Johnson Space Center have developed a software tool that allows multiple users to collaborate on developing and designing spacecraft deorbit opportunities. It was originally designed to support the space shuttle and the International Space Station, but can be utilized for any space vehicle deorbit calculations. Once key parameters and variables are entered, the software algorithms generate deorbit opportunity information, sun angle violations, and ascending node information.


  • State-of-the-Art: This software is the latest generation of software algorithms to calculate deorbit opportunities


  • Determining and planning for spacecraft deorbit opportunities

Licensing and Partnering Opportunity

This technology is being made available through JSC's Technology Transfer and Commercialization Office, which seeks to transfer technology into and out of NASA to benefit the space program and U.S. industry. NASA invites companies to consider licensing this technology for commercial applications.
