Satellite Capture Mechanism in a Sun-Planet-Binary Four-Body System
Satellite capture mechanism in a sun-planet-binary four-body system Shengping Gong*, Miao Li † School of Aerospace Engineering, Tsinghua University, Beijing China, 100084 Abstract This paper studies the binary disruption problem and asteroid capture mechanism in a sun-planet-binary four-body system. Firstly, the binary disruption condition is studied and the result shows that the binary is always disrupted at the perigee of their orbit instantaneously. Secondly, an analytic expression to describe the energy exchange between the binary is derived based on the ‘instantaneous disruption’ hypothesis. The analytic result is validated through numerical integration. We obtain the energy exchange in encounters simultaneously by the analytic expression and numerical integration. The maximum deviation of this two results is always less than 25% and the mean deviation is about 8.69%. The analytic expression can give us an intuitive description of the energy exchange between the binary. It indicates that the energy change depends on the hyperbolic shape of the binary orbit with respect to the planet, the masses of planet and the primary member of the binary, the binary phase at perigee. We can illustrate the capture/escape processes and give the capture/escape region of the binary clearly by numerical simulation. We analyse the influence of some critical *Associate professor, School of Aerospace Engineering; [email protected] † PhD candidate, School of Aerospace Engineering; [email protected] 1 factors to the capture region finally.

The Formation of the Martian Moons Rosenblatt P., Hyodo R
The Final Manuscript to Oxford Science Encyclopedia: The formation of the Martian moons Rosenblatt P., Hyodo R., Pignatale F., Trinh A., Charnoz S., Dunseath K.M., Dunseath-Terao M., & Genda H. Summary Almost all the planets of our solar system have moons. Each planetary system has however unique characteristics. The Martian system has not one single big moon like the Earth, not tens of moons of various sizes like for the giant planets, but two small moons: Phobos and Deimos. How did form such a system? This question is still being investigated on the basis of the Earth-based and space-borne observations of the Martian moons and of the more modern theories proposed to account for the formation of other moon systems. The most recent scenario of formation of the Martian moons relies on a giant impact occurring at early Mars history and having also formed the so-called hemispheric crustal dichotomy. This scenario accounts for the current orbits of both moons unlike the scenario of capture of small size asteroids. It also predicts a composition of disk material as a mixture of Mars and impactor materials that is in agreement with remote sensing observations of both moon surfaces, which suggests a composition different from Mars. The composition of the Martian moons is however unclear, given the ambiguity on the interpretation of the remote sensing observations. The study of the formation of the Martian moon system has improved our understanding of moon formation of terrestrial planets: The giant collision scenario can have various outcomes and not only a big moon as for the Earth. -
Mining Asteroids and Exploring Resources in Space, By
Mining Asteroids and Exploring Resources in Space Puneet Bhalla Exploration is intrinsic to mankind which has forever sought newer frontiers, primarily for scientific discovery and for economic gains. Extra- terrestrial missions beyond the Earth orbit into deeper space have until now pursued the former. However, with a growing realisation of depleting natural resources on Earth, the focus has shifted equally to seeking celestial bodies that can be mined for further use. Until now seen mostly in the realm of science fiction, today, space mining is being brought closer to reality through advanced technologies and directed investments. Scientists have been studying asteroids by analysing meteorite samples found on Earth and by telescopic studies. Asteroids are rocky bodies, varying from a few metres across to the largest Ceres (averaging 952 km in diameter, also called a ‘dwarf planet’), orbiting the sun. Most of the millions of asteroids in the solar system are found between the orbits of Mars and Jupiter in the ‘main asteroid belt’. Among asteroids outside this belt, astronomers have discovered more than 10,000 near Earth asteroids (more of them continue to be discovered) whose orbital trajectories bring them close to Earth. Of these, nearly 9,000 are known to be larger than 150 ft in diameter. Group Captain Puneet Bhalla is Senior Fellow, Centre for Land Warfare Studies, New Delhi. N.B.

Asteroid Mining with Small Spacecraft and Its Economic Feasibility
Asteroid mining with small spacecraft and its economic feasibility Pablo Callaa,, Dan Friesb, Chris Welcha aInternational Space University, 1 Rue Jean-Dominique Cassini, 67400 Illkirch-Graffenstaden, France bInitiative for Interstellar Studies, Bone Mill, New Street, Charfield, GL12 8ES, United Kingdom Abstract Asteroid mining offers the possibility to revolutionize supply of resources vital for human civilization. Pre- liminary analysis suggests that Near-Earth Asteroids (NEA) contain enough volatile and high value minerals to make the mining process economically feasible. Considering possible applications, specifically the mining of water in space has become a major focus for near-term options. Most proposed projects for asteroid mining involve spacecraft based on traditional designs resulting in large, monolithic and expensive systems. An alternative approach is presented in this paper, basing the asteroid mining process on multiple small spacecraft. To the best knowledge of the authors, only limited analysis of the asteroid mining capability of small spacecraft has been conducted. This paper explores the possibility to perform asteroid mining operations with spacecraft that have a mass under 500 kg and deliver 100 kg of water per trip. The mining process considers water extraction through microwave heating with an efficiency of 2 Wh/g.The proposed, small spacecraft can reach NEAs within a range of ∼ 0:03 AU relative to earth's orbit, offering a delta V of 437 m/s per one-way trip. A high-level systems engineering and economic analysis provides a closed spacecraft design as a baseline and puts the cost of the proposed spacecraft at $ 113.6 million/unit. The results indicate that more than one hundred spacecraft and their successful operation for over five years are required to achieve a financial break-even point. -

Det första steget är att omdirigera en asteroid till en stabil omloppsbana runt jorden så att gruvteknik kan demon- streras. Bromsning av asteroidens tumlande är en av de viktigaste stegen i ett rymduppdrag där en asteroid ska omdirigeras. I detta examensarbete föreslås en preliminär asteroidlandare baserad på CubeSat-teknik för ett rymduppdrag där en asteroid ska omdirigeras. En asteroid av Arjuna-typ, 2014 UR, med en diameter på mellan 10.6 och 21.2 m är vald som kandidat för rymduppdraget. -
Harvesting Near Earth Asteroid Resources Using Solar Sail Technology
Harvesting Near Earth Asteroid Resources Using Solar Sail Technology By Colin McINNES Systems, Power and Energy Division, School of Engineering, University of Glasgow, UK (Received 1st Dec, 2016) Near Earth asteroids represent a wealth of material resources to support future space ventures. These resources include water from C-type asteroids for crew logistic support; liquid propellants electrolytically cracked from water to fuel crewed vehicles and commercial platforms; and metals from M-type asteroids to support in-situ manufacturing. In this paper the role of solar sail technology will be investigated to support the future harvesting of near Earth asteroid resources. This will include surveying candidate asteroids though in-situ sensing, efficiently processing asteroid material resources and returning such resources to near-Earth space. While solar sailing can be used directly as a low cost means of transportation to and from near Earth asteroids, solar sail technology itself offers a number of dual-use applications. For example, solar sails can in principle be used as solar concentrators to sublimate material. If a metal-rich M-type asteroid is processed through solar heating, then the flow of metal resources made available could be manufactured into further reflective area. The additional thermal power generated would then accelerate the manufacturing process. Such a strategy could enable rapid in-situ processing of asteroid resources with exponential scaling laws. It is proposed that solar sailing therefore represents a key technology for harvesting near Earth asteroids, using sunlight both as heat for asteroid processing and radiation pressure for resource transportation. Key Words: Solar sail, solar radiation pressure, near Earth asteroid, space resources Nomenclature Earth orbit or at the Lagrange points, or a range of commercial space platforms. -
Technology Development for NASA's Asteroid Redirect Mission
IAC-14-D2.8-A5.4.1 TECHNOLOGY DEVELOPMENT FOR NASA’s ASTEROID REDIRECT MISSION Dr. Christopher Moore National Aeronautics and Space Administration, USA [email protected] Abstract NASA is developing concepts for the Asteroid Redirect Mission (ARM), which would use a robotic spacecraft to capture a small near-Earth asteroid, or remove a boulder from the surface of a larger asteroid, and redirect it into a stable orbit around the moon. Astronauts launched aboard the Orion crew capsule and the Space Launch System rocket would rendezvous with the captured asteroid mass in lunar orbit, and collect samples for return to Earth. This mission will advance critical technologies needed for human exploration in cis-lunar space and beyond. The ARM could also demonstrate the initial capabilities for defending our planet against the threat of catastrophic asteroid impacts. NASA projects are maturing the technologies for enabling the ARM, which include high-power solar electric propulsion, asteroid capture systems, optical sensors for asteroid rendezvous and characterization, advanced space suits and EVA tools, and the utilization of asteroid resources. Many of the technologies being developed for the ARM may also have commercial applications such as satellite servicing and asteroid mining. INTRODUCTION NASA is developing concepts for the Asteroid space science in order to make progress toward a range Redirect Mission (ARM), which would use a robotic of objectives, including: spacecraft with a solar electric propulsion system to • Conduct a human exploration mission to an asteroid capture a small near-Earth asteroid, or to remove a in the mid-2020’s, providing systems and boulder from the surface of a larger asteroid. -
