      In 2022 NASA’s DART spacecraft made history, and changed the Solar System forever, by impacting the Dimorphos asteroid and measurably shifting its orbit around the larger Didymos asteroid. In the process a plume of debris was thrown out into space.
      The latest modelling, available on the preprint server arXiv and accepted for publication in the September volume of The Planetary Science Journal, shows how small meteoroids from that debris could eventually reach both Mars and Earth – potentially in an observable (although quite safe) manner.

      NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado (CU) Boulder enacted a collaborative Space Act Agreement Monday, Aug. 5, 2024, to advance research and modeling in the critical field of space weather.
      NASA and LASP are longtime space science and exploration partners, and this formal agreement expands the depth and breadth of space weather activities for everyone’s benefit. Space weather refers to conditions in space — typically driven by the Sun’s activity — that can affect humans and technology. Space weather is responsible for the aurora, and intense events can harm spacecraft, astronauts, or even technology on Earth.
      NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado (CU) Boulder enacted a collaborative Space Act Agreement to advance research and modeling in the critical field of space weather. Goddard Center Director Dr. Makenzie Lystrup (left) and LASP Director Dr. Daniel Baker signed the agreement Monday, Aug. 5, 2024.NASA/Bri Horton “Space weather touches all aspects of life, from our power grid to space-based assets that are susceptible to space weather events,” said Dr. Makenzie Lystrup, NASA Goddard director. “This agreement today formalizes a long-standing collaboration with LASP essential to expanding space weather applications that protect ground- and space-based assets, not to mention our astronauts preparing to explore deeper into space to the Moon and beyond.” 
      LASP is at the forefront of solar, planetary, and space physics research, climate and space-weather monitoring, and the search for evidence of habitable worlds, all of which match perfectly with Goddard’s mission portfolio and leadership in heliophysics research.
      “We have had a long and highly productive partnership with NASA’s Goddard Space Flight Center in all areas of space exploration,” said LASP Director Dr. Daniel Baker. “It is now an honor for LASP to collaborate with the world’s largest Earth and space science research organization to advance our nation’s space weather and heliophysics capabilities. This agreement offers new opportunities to learn from our overlapping space weather expertise and to leverage scientific research using small satellites.”
      The agreement calls for a more formal and robust framework to expand space weather work in several key areas, to include:
      Maturation and miniaturization of instruments for space weather research Incorporating space weather instrumentation and packages as hosted payloads on satellites Exploring joint work in “Space Weather Research to Operations” activities Addressing important aspects of space weather policy And, defining best practices for mission proposal development Goddard is NASA’s premiere spaceflight complex and home to the nation’s largest organization of scientists, engineers, and technologists who build spacecraft, instruments, and new technology to study Earth, the Sun, our solar system, and the universe.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA Johnson Space Center: ORDEM represents the state of the art in orbital debris models intended for engineering analysis. It is a data-driven model, relying on large quantities of radar, optical, in situ, and laboratory measurement data. When released, it was the first software code to include a model for different orbital debris material densities, population models from low Earth orbit (LEO) all the way to Geosynchronous orbit (GEO), and uncertainties in each debris population. 
      ORDEM allows users to compute the orbital debris flux on any satellite in Earth orbit.  This allows satellite designers to mitigate possible orbital debris damage to a spacecraft and its instruments using shielding and design choices, thereby extending the useful life of the mission and its experiments.  The model also has a mode that simulates debris telescope/radar observations from the ground.  Both it and the spacecraft flux mode can be used to design experiments to measure the meteoroid and orbital debris environments. 
      ORDEM is used heavily in the hypervelocity protection community, those that design, build, and test shielding for spacecraft and rocket upper stages. The fidelity of the ORDEM model allows for the optimization of shielding to balance mission success criteria, risk posture, and cost considerations. 
      As both government and civilian actors continue to exploit the space environment for security, science, and the economy, it is important that we track the debris risks in increasingly crowded orbits, in order to minimize damage to these space assets to make sure these missions continue to operate safely.  ORDEM is NASA’s primary tool for computing and mitigating these risks.   
      ORDEM is used by NASA, the Department of Defense, and other U.S. government agencies, directly or indirectly (via the Debris Assessment Software, MSC-26690-1) to evaluate collision risk for large trackable objects, as well as other mission-ending risks associated with small debris (such as tank ruptures or wiring cuts). In addition to the use as an engineering tool, ORDEM has been used by NASA and other missions in the conceptual design phase to analyze the frequency of orbital debris impacts on potential in situ sensors that could detect debris too small to be detected from ground-based assets. 
      Commercial and academic users of ORDEM include Boeing, SpaceX, Northrop Grumman, the University of Colorado, California Polytechnic State University, among many others. These end users, similar to the government users discussed above, use the software to (1) directly determine potential hazards to spaceflight resulting from flying through the debris environment, and (2) research how the debris environment varies over time to better understand what behaviors may be able to mitigate the growth of the environment. 
      The quality and quantity of data available to the NASA Orbital Debris Program Office (ODPO) for the building, verification, and validation of the ORDEM model is greater than for any other entity that performs similar research. Many of the models used by other research and engineering organizations are derived from the models that ODPO has published after developing them for use in ORDEM.

      3 Min Read NASA Sponsors New Research on Orbital Debris, Lunar Sustainability
      From lunar orbit, astronauts pointed cameras out the window of their spacecraft to capture photos of the moon's surface. Credits: NASA As part of NASA’s commitment to foster responsible exploration of the universe for the benefit of humanity, the Office of Technology, Policy, and Strategy (OTPS) is funding space sustainability research proposals from five university-based teams to analyze critical economic, social, and policy issues related to Earth’s orbit and cislunar space.
      The new research awards reflect the agency’s commitment identified in NASA’s Space Sustainability Strategy to ensure safe, peaceful, and responsible space exploration for future generations, and encourage sustainable behaviors in cislunar space and on the lunar surface by ensuring that current operations do not impact those yet to come.
      Three of the five awards will fund research that addresses the growing problem of orbital debris, human-made objects in Earth’s orbit that no longer serve a purpose. This debris can endanger spacecraft, jeopardize access to space, and impede the development of a low-Earth orbit economy. 
      The remaining two awards focus on lunar surface sustainability and will address key policy questions such as the protection of valuable locations and human heritage sites as well as other technical, economic, or cultural considerations that may factor into mission planning. 
      “The sustainable use of space is critical to current and future space exploration,” said Ellen Gertsen, deputy associate administrator for the Office of Technology, Policy, and Strategy (OTPS) at NASA Headquarters in Washington. “Mitigating the risks of orbital debris and ensuring future generations can utilize the lunar surface are of paramount importance. These awards will fund research to help us understand the economics, the policy considerations, and the social elements of sustainability, generating new tools and evidence so we can make better-informed decisions.” 
      A panel of NASA experts selected the following proposals, awarding a total of about $550,000 to fund them: 
      Lunar surface sustainability 
      “A RAD Framework for the Moon: Applying Resist-Accept-Direct Decision-Making,” submitted by Dr. Caitlin Ahrens of the University of Maryland, College Park  “Synthesizing Frameworks of Sustainability for Futures on the Moon,” submitted by research scientist Afreen Siddiqi of Massachusetts Institute of Technology  Orbital Debris and Space Sustainability 
      “Integrated Economic-Debris Modeling of Active Debris Removal to Inform Space Sustainability and Policy,” submitted by researcher Mark Moretto of the University of Colorado, Boulder  “Avoiding the Kessler Syndrome Through Policy Intervention,” submitted by aeronautics and astronautics researcher Richard Linares of the Massachusetts Institute of Technology  “Analysis of Cislunar Space Environment Scenarios, Enabling Deterrence and Incentive-Based Policy,” submitted by mechanical and aerospace engineering researcher Ryne Beeson of Princeton University  Share
