Abstract NASA's Double Asteroid Redirection Test (DART) mission was the first to demonstrate asteroid deflection, and mission's Level 1 requirements guided its planetary defense investigations. Here, we summarize DART's achievement of those requirements. On 2022 September 26, DART spacecraft impacted Dimorphos, secondary member Didymos near-Earth binary system, demonstrating an autonomously navigated kinetic impact into with limited prior knowledge for defense. Months subsequent Earth-based...
Abstract The NASA Double Asteroid Redirection Test (DART) spacecraft successfully crashed on Dimorphos, the secondary component of binary (65803) Didymos system. Following impact, a large dust cloud was released, and long-lasting tail developed. We have extensively monitored from ground Hubble Space Telescope. provide characterization ejecta properties, i.e., particle size distribution ejection speeds, geometric parameters, mass, by combining both observational data sets using Monte Carlo...
The Earth-Moon system is constantly bombarded by meteoroids of different size and impact speed. Observation the impacts on Moon can enable thorough characterization Lunar meteoroid flux, which similar to that Earth. While Earth-based observations are restricted weather, geometric illumination conditions, a Lunar-based observation campaign improve detection rate and, when observing far side, complement in both space time taken from Meteoroid Impact Observer (LUMIO), one two winning concepts...
Abstract Numerous missions leverage the weak stability boundary in Earth–Moon–Sun system to achieve a safe and cost-effective access lunar environment. These transfers are envisaged play significant role upcoming missions. This paper proposes novel method design low-energy by combining recent Theory of Functional Connections with homotopic continuation approach. Planar patched transfer legs within Earth–Moon Sun–Earth systems continued into higher-fidelity models. Eventually, full is...
The Lunar Meteoroid Impact Observer (LUMIO) is a CubeSat mission at the Earth-Moon Lagrangian point 2 (L<inf>2</inf>) designed to observe, quantify, and characterize meteoroid impacts by detecting their flashes on farside. LUMIO can be deployed as one of payloads in NASA Commercial Payload System or from Artemis-2 low orbit demonstrate autonomous navigation capabilities reach its operational around L<inf>2</inf>. From there, scientific map investigate spatial temporal characteristics...
Meteoroids constantly impact the Earth–Moon system, posing risks to space assets and threatening life on Earth. By studying lunar surface impacts, detailed information regarding meteoroid magnitudes, velocities, distributions can be obtained, improving models validating studies. The LUMIO CubeSat mission aims observe characterize impacts farside, enhancing situational awareness complementing Earth-based observations. This study discusses design analysis of LUMIO, with a focus utilizing weak...
The NASA/DART (Double Asteroid Redirection Test) spacecraft successfully crashed on Dimorphos, the secondary component of binary (65803) Didymos system. Following impact, a large dust cloud was released, and long-lasting tail developed. We have extensively monitored from ground Hubble Space Telescope (HST). provide characterization ejecta properties, i.e., particle size distribution ejection speeds, geometric parameters, mass, by combining both observational data sets, using Monte Carlo...
Trajectory design in highly-perturbed environments like binary asteroids is challenging. It typically requires using realistic, non-autonomous dynamical models which periodic solutions derived autonomous systems vanish. In this work, Lagrangian descriptors are employed the perturbed planar bi-elliptic restricted four-body problem to find regions of bounded motion over a finite horizon about Dimorphos, secondary body (65803) Didymos system. Results show that successfully reveal phase space...
The space sector is experiencing a flourishing growth and evidence mounting that the near future will be characterized by large amount of deep-space missions. In last decade, CubeSats have granted affordable access to due their reduced manufacturing costs compared traditional At present-day, most miniaturized spacecraft thus far been deployed into near-Earth orbits, but soon multitude interplanetary employed for missions as well. Nevertheless, current paradigm strongly relies on ground-based...
