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 has selected four new crew members to participate in the final simulated mission to Mars in 2024 inside the agency’s Human Exploration Research Analog. From left are Kristen Magas, Anderson Wilder, Obaid Alsuwaidi, and Tiffany Snyder.Credit: C7M4 Crew NASA selected a crew of four research volunteers to participate in its last simulated mission to Mars in 2024 within a habitat at the agency’s Johnson Space Center in Houston.
Obaid Alsuwaidi, Kristen Magas, Tiffany Snyder, and Anderson Wilder will step into the 650-square-foot HERA (Human Exploration Research Analog) facility on Friday, Nov. 1. Once inside, the team will live and work like astronauts for 45 days. The crew will exit the facility on Monday, Dec. 16, after simulating their return to Earth. Jordan Hundley and Robert Wilson also were named as alternate crew members.
Scientists use HERA studies to examine how crew members adapt to isolation, confinement, and remote conditions before NASA sends astronauts on deep space missions to the Moon, Mars, and beyond. The studies provide data about human health and performance in an enclosed environment over time with crews facing different challenges and tasks.
The four volunteers will carry out scientific research and operational tasks throughout their simulated mission, including raising shrimp, growing vegetables, and “walking” on the surface of Mars using virtual reality. They will also experience communication delays lasting up to five minutes as they “near” Mars, allowing researchers to see how crews may respond to the type of delays astronauts will encounter in deep space. Astronauts traveling to the Red Planet may encounter one-way communication delays lasting as long as 20 minutes.
As with the previous HERA missions, crew members will conduct 18 human health studies during the mission through NASA’s Human Research Program. Collectively, the work helps scientists understand how a spaceflight-like environment contributes to the physiological, behavioral, and psychological health of crew members. Insights gleaned from the studies will allow researchers to develop and test strategies aimed at helping astronauts overcome obstacles on deep space missions.

NASA Selects Two Teams to Advance Life Sciences Research in Space
NASA announced two awards Thursday to establish scientific consortia – multi-institutional coalitions to conduct ground-based studies that help address the agency’s goals of maintaining a sustained human presence in space. These consortia will focus on biological systems research in the areas of animal and human models, plants, and microbiology. When fully implemented, the awards for these consortia will total about $5 million.
Space biology efforts at NASA use the unique environment of space to conduct experiments impossible to do on Earth. Such research not only supports the health and welfare of astronauts, but results in breakthroughs on diseases such as cancer and neurodegenerative disorders to help protect humanity down on the ground.
The awards for the two consortia are for the following areas:
Studying space biosphere. The Biology in Space: Establishing Networks for DUrable & REsilient Systems consortium involves a collaborative effort between human/animal, plant, and microbial biologists to ensure an integrated view of the space flight biosphere by enhancing data acquisition, modeling, and testing. It will include participation of more than thirty scientists and professionals working together from at least three institutions. Led by Kristi Morgansen at the University of Washington in Seattle, Washington. Converting human waste into materials for in-space biomanufacturing. The Integrative Anaerobic Digestion and Phototrophic Biosystem for Sustainable Space Habitats and Life Supports consortium will develop an anaerobic digestion process that converts human waste into organic acids and materials that can be used for downstream biomanufacturing applications in space. It will include eight scientists from six different institutions in three different states, including Delaware and Florida. The consortium is led by Yinjie Tang at Washington University in St. Louis, Missouri. Proposals for these consortia were submitted in response to ROSES 2024 Program Element E.11 Consortium in Biological Sciences for a consortium with biological sciences expertise to carry out research investigations and conduct activities that address NASA’s established interests in space life sciences.
NASA’s Space Biology Program within the agency’s Biological and Physical Sciences division conducts research across a wide spectrum of biological organization and model systems to probe underlying mechanisms by which organisms acclimate to stressors encountered during space exploration (including microgravity, ionizing radiation, and elevated concentrations of carbon dioxide). This research informs how biological systems regulate and sustain growth, metabolism, reproduction, and development in space and how they repair damage and protect themselves from infection and disease.

4 Min Read NASA to Embrace Commercial Sector, Fly Out Legacy Relay Fleet
An artist's concept of commercial and NASA space relays. Credits: NASA/Morgan Johnson NASA is one step closer on its transition to using commercially owned and operated satellite communications services to provide future near-Earth space missions with increased service coverage, availability, and accelerated science and data delivery.
As of Friday, Nov. 8, the agency’s legacy TDRS (Tracking and Data Relay Satellite) system, as part of the Near Space Network, will support only existing missions while new missions will be supported by future commercial services.
“There have been tremendous advancements in commercial innovation since NASA launched its first TDRS satellite more than 40 years ago,” said Kevin Coggins, deputy associate administrator of NASA’s SCaN (Space Communications and Navigation) program. “TDRS will continue to provide critical support for at least the next decade, but now is the time to embrace commercial services that could enhance science objectives, expand experimentation, and ultimately provide greater opportunities for discovery.”

Just as NASA has adopted commercial crew, commercial landers, and commercial transport services, the Near Space Network, managed by NASA’s SCaN, will leverage private industry’s vast investment in the Earth-based satellite communications market, which includes communications on airplanes, ships, satellite dish television, and more. Now, industry is developing a new space-based market for these services, where NASA plans to become one of many customers, bolstering the domestic space industry.
NASA’s Communications Services Project is working with industry through funded Space Act Agreements to develop and demonstrate commercial satellite communications services that meet the agency’s mission needs, and the needs of other potential users.
In 2022, NASA provided $278.5 million in funding to six domestic partners so they could develop and demonstrate space relay communication capabilities.

Kuiper Government Solutions (KGS) LLC SES Government Solutions Space Exploration Technologies (SpaceX) Telesat U.S. Services LLC Viasat Incorporated Read More About the CSP Partners An artist’s concept of commercial relay satellites. NASA/Morgan Johnson A successful space-based commercial service demonstration would encompass end-to-end testing with a user spacecraft for one or more of the following use cases: launch support, launch and early operations phase, low and high data rate routine missions, terrestrial support, and contingency services. Once a demonstration has been completed, it is expected that the commercial company would be able to offer their services to government and commercial users.
NASA also is formulating non-reimbursable Space Act Agreements with members of industry to exchange capability information as a means of growing the domestic satellite communications market. The Communications Services Project currently is partnered with Kepler Communications US Inc. through a non-reimbursable Space Act Agreement.
As the agency and the aerospace community expand their exploration efforts and increase mission complexity, the ability to communicate science, tracking, and telemetry data to and from space quickly and securely will become more critical than ever before. The goal is to validate and deliver space-based commercial communications services to the Near Space Network by 2031, to support future NASA missions.
NASA’s Tracking and Data Relay System
While TDRS will not be accepting new missions, it won’t be retiring immediately. Current TDRS users, like the International Space Station, Hubble Space Telescope, and many other Earth- and universe-observing missions, will still rely on TDRS until the mid-2030s. Each TDRS spacecraft’s retirement will be driven by individual health factors, as the seven active TDRS satellites are expected to decline at variable rates.

Each successive generation of TDRS improved upon the previous model, with additional radio frequency band support and increased automation.
The first TDRS was designed for a mission life of 10 years, but lasted 26 years before it was decommissioned in 2009. The last in the third generation – TDRS-13 –was launched Aug. 18, 2017.
The TDRS constellation has been a workhorse for the agency, enabling significant data transfer and discoveries.”
