The National Aeronautics and Space Administration (NASA) Ames Research Center (ARC) on behalf of the Space Technology Mission Directorate’s (STMD) Small Spacecraft Technology (SST) Program and is hereby soliciting information from potential sources for inputs on industry, academia, or government adopted battery passivation techniques. As part of a continual process improvement effort and potential requirement revisions, the NASA Small Spacecraft community, Office of Safety and Mission Assurance, and Orbital Debris Program Office are seeking inputs from industry on battery passivation techniques that are used by industry to satisfy the Orbital Debris Mitigation Standard Practices (ODMSP) requirements 2-2. Limiting the risk to other space systems from accidental explosions and associated orbital debris after completion of mission operations: All on-board sources of stored energy of a spacecraft or upper stage should be depleted or safed when they are no longer required for mission operations or post mission disposal. Depletion should occur as soon as such an operation does not pose an unacceptable risk to the payload. Propellant depletion burns and compressed gas releases should be designed to minimize the probability of subsequent accidental collision and to minimize the impact of a subsequent accidental explosion.
Background
NASA has well-established procedures for passivating power sources on large, highly redundant spacecraft to mitigate debris generation at end-of-life. However, the rise of capable small spacecraft utilizing single-string and Commercial Off-The-Shelf (COTS) components presents challenges. Directly applying passivation strategies designed for redundant systems to these less complex spacecraft can introduce risks and may not be cost-effective for these missions.
Recognizing that the commercial sector has emerged as a leader in Low Earth Orbit (LEO) small satellite operations, NASA seeks to engage with industry, academia, and government spacecraft operators to gain insights into current battery passivation techniques. Understanding industry-adopted practices, their underlying rationale, and performance data will inform NASA’s ongoing efforts to develop safe and sustainable end-of-life procedures for future missions.
NASA invites government, academic, or industry stakeholders, including small satellite operators, manufacturers, and component suppliers, to share information on battery passivation strategies employed in their spacecraft.

NASA/Bill Ingalls NASA Administrator Bill Nelson and Kirk Johnson, Sant Director of the Smithsonian’s National Museum of Natural History in Washington, preview the agency’s new Earth Information Center exhibit on Monday, Oct. 8, 2024. This new exhibit is the Earth Information Center’s second physical location.
The exhibit at the Smithsonian includes a 32-foot-long, 12-foot-high video wall displaying Earth science data visualizations and videos, interpretive panels showing Earth’s connected systems, information on our changing world, and an overview of how NASA and the Smithsonian study our home planet. It opens to the public Tuesday, Oct. 8, and will remain on display through 2028.

Space for Earth is an immersive experience that is part of the Earth Information Center. Credit: NASA Media is invited to preview and interview NASA leadership ahead of the opening of the Earth Information Center at the Smithsonian National Museum of Natural History at 10 a.m. EDT, Monday, Oct. 7.
The 2,000-square-foot exhibit includes a 32-foot-long, 12-foot-high video wall displaying Earth science data visualizations and videos, an interpretive panel showing Earth’s connected systems, information on our changing world, and an overview of how NASA and the Smithsonian study our home planet. Visitors also can explore Earth observing missions, changes in Earth’s landscape over time, and how climate is expected to change regionally through multiple interactive experiences.
The event will take place at the Smithsonian National Museum of Natural History 1000 Constitution Ave. NW, Washington from 10 a.m. to 3 p.m. Members of the media interested in attending should email Liz Vlock at: elizabeth.a.vlock@nasa.gov. NASA’s media accreditation policy is available online.
Participants will be available for media interviews starting at the following times:
10 a.m.: NASA Administrator Bill Nelson 10 a.m.: Kirk Johnson, Sant director, Museum of Natural History 10:30 a.m.: Karen St. Germain, division director, NASA Earth Sciences Division 10:30 a.m.: Julie Robinson, deputy director, NASA Earth Sciences Division The Earth Information Center draws insights from across all NASA centers and its fellow partners – National Oceanic and Atmospheric Administration, U.S. Geological Survey, U.S. Department of Agriculture, U.S. Agency for International Development, Environmental Protection Agency, and Federal Emergency Management Administration. It allows viewers to see how our home planet is changing and gives decision makers information to develop the tools they need to mitigate, adapt, and respond to climate change.
NASA’s Earth Information Center is a virtual and physical space designed to aid people to make informed decisions on Earth’s environment and climate. It provides easily accessible, readily usable, and scalable Earth information – enabling global understanding of our changing planet.
The expansion of the physical Earth Information Center at the Smithsonian National Museum of Natural History Museum makes it the second location in the Washington area. The first is located at NASA Headquarters in Washington at 300 E St., SW.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA is exploring potential partnerships for alternate use cases for the On-orbit Servicing, Assembly, and Manufacturing 1 (OSAM-1) flight hardware, test facilities, and experienced personnel. Through a Request for Information for OSAM-1 Partnerships released Sept. 5, 2024, NASA seeks interest from U.S. organizations that will benefit commercial, civil, and national objectives, thereby advancing domestic leadership in In-space Servicing, Assembly, and Manufacturing (ISAM) capabilities.
A comprehensive list of OSAM-1 resources and technologies organizations can consider using are outlined in the full Request for Information for OSAM-1 Partnerships available at www.sam.gov. Responses are due Sept. 30, 2024, by 11:59 p.m. EDT.
