Hayabusa2 and the Formation of the Solar System PPS02-25
PPS02-25 JpGU-AGU Joint Meeting 2017 Hayabusa2 and the formation of the Solar System *Sei-ichiro WATANABE1,2, Hayabusa2 Science Team2 1. Division of Earth and Planetary Sciences, Graduate School of Science, Nagoya University, 2. JAXA/ISAS Explorations of small solar system bodies bring us direct and unique information about the formation and evolution of the Solar system. Asteroids may preserve accretion processes of planetesimals or pebbles, a sequence of destructive events induced by the gas-driven migration of giant planets, and hydrothermal processes on the parent bodies. After successful small-body missions like Rosetta to comet 67P/Churyumov-Gerasimenko, Dawn to Vesta and Ceres, and New Horizons to Pluto, two spacecraft Hayabusa2 and OSIRIS-REx are now traveling to dark primitive asteroids.The Hayabusa2 spacecraft journeys to a C-type near-earth asteroid (162173) Ryugu (1999 JU3) to conduct detailed remote sensing observations and return samples from the surface. The Haybusa2 spacecraft developed by Japan Aerospace Exploration Agency (JAXA) was successfully launched on 3 Dec. 2014 by the H-IIA Launch Vehicle and performed an Earth swing-by on 3 Dec. 2015 to set it on a course toward its target. The spacecraft will reach Ryugu in the summer of 2018, observe the asteroid for 18 months, and sample surface materials from up to three different locations. The samples will be delivered to the Earth in Nov.-Dec. 2020. Ground-based observations have obtained a variety of optical reflectance spectra for Ryugu. Some reported the 0.7 μm absorption feature and steep slope in the short wavelength region, suggesting hydrated minerals. -
Rules for the Heavens: the Coming Revolution in Space and the Laws of War
RULES FOR THE HEAVENS: THE COMING REVOLUTION IN SPACE AND THE LAWS OF WAR John Yoo* Great powers are increasing their competition in space. Though Russia and the United States have long relied on satellites for surveillance of rival nations’ militaries and the detection of missile launches, the democratization of space through technological advancements has allowed other nations to assert greater control. This Article addresses whether the United States and other nations should develop the space-based weapons that these policies promise, or whether they should cooperate to develop new international agreements to ban them. In some areas of space, proposals for regulation have already come too late. The U.S.’s nuclear deterrent itself depends cru- cially on space: ballistic missiles leave and then re-enter the atmosphere, giving them a global reach without serious defense. As more nations develop nuclear weapons and intercontinental ballistic missile (ICBM) technology, outer space will become even more important as an arena for defense against weapons of mass destruction (WMD) proliferation. North Korea’s progress on ICBM and nuclear technology, for example, will prompt even greater in- vestment in space-based missile defense systems. This Article makes two contributions. First, it argues against a grow- ing academic consensus in favor of a prohibition on military activities in space. It argues that these scholars over-read existing legal instruments and practice. While nations crafted international agreements to bar WMDs in outer space, they carefully left unregulated reconnaissance and commu- nications satellites, space-based conventional weapons, antisatellite sys- tems, and even WMDs that transit through space, such as ballistic missiles. -

Glossary Glossary
Glossary Glossary Albedo A measure of an object’s reflectivity. A pure white reflecting surface has an albedo of 1.0 (100%). A pitch-black, nonreflecting surface has an albedo of 0.0. The Moon is a fairly dark object with a combined albedo of 0.07 (reflecting 7% of the sunlight that falls upon it). The albedo range of the lunar maria is between 0.05 and 0.08. The brighter highlands have an albedo range from 0.09 to 0.15. Anorthosite Rocks rich in the mineral feldspar, making up much of the Moon’s bright highland regions. Aperture The diameter of a telescope’s objective lens or primary mirror. Apogee The point in the Moon’s orbit where it is furthest from the Earth. At apogee, the Moon can reach a maximum distance of 406,700 km from the Earth. Apollo The manned lunar program of the United States. Between July 1969 and December 1972, six Apollo missions landed on the Moon, allowing a total of 12 astronauts to explore its surface. Asteroid A minor planet. A large solid body of rock in orbit around the Sun. Banded crater A crater that displays dusky linear tracts on its inner walls and/or floor. 250 Basalt A dark, fine-grained volcanic rock, low in silicon, with a low viscosity. Basaltic material fills many of the Moon’s major basins, especially on the near side. Glossary Basin A very large circular impact structure (usually comprising multiple concentric rings) that usually displays some degree of flooding with lava. The largest and most conspicuous lava- flooded basins on the Moon are found on the near side, and most are filled to their outer edges with mare basalts. -

Powell | Published: Monday, January 4, 2021 Whatever craziness may be happening on Earth, the coming year promises to be a spectacular one across the solar system. 2020 - It was the worst of times, it was the best of times. First landing on the lunar farside, two impressive successes in gathering samples from asteroids, the first new pieces of the Moon brought home in 44 years, close-up explorations of the Sun, and major advances in low-cost reusable rockets. First Visit to Jupiter's Trojan Asteroids First Visit to Jupiter's Trojan Asteroids In October, NASA is set to launch the Lucy spacecraft. Over its 12-year primary mission, Lucy will visit eight different asteroids. One target lies in the asteroid belt. The other seven are so-called Trojan asteroids that share an orbit with Jupiter, trapped in points of stability 60 degrees ahead of or behind the planet as it goes around the sun. These objects have been trapped in their locations for billions of years, probably since the time of the formation of the solar system. They contain preserved samples of water-rich and carbon-rich material in the outer solar system; some of that material formed Jupiter, while other bits moved inward to contribute to Earth's life-sustaining composition. As a whimsical aside: When meteorites strike carbon-rich asteroids, they create tiny carbon crystals. -
Lori Garver, NASA Deputy Administrator SOFIA Joining Forces Event Joint Base Andrews September 22, 2011
Lori Garver, NASA Deputy Administrator SOFIA Joining Forces Event Joint Base Andrews September 22, 2011 Good afternoon. My name is Lori Garver, Deputy Administrator at NASA. I want to thank our German Aerospace Center partners and Joint Base Andrews for organizing this event and especially for making it possible for students and the children of military families to see this unique flying observatory up close. And let me just take a moment to commend First Lady Michelle Obama and Jill Biden for devoting their time and energy in encouraging all Americans to do more in support of the wives, husbands, sons, daughters and other family members of our men and women in uniform who are defending our freedom around the world. 1 I want to also welcome any and all Members of Congress who are here today. And a special hello to Mary Blessing, an astronomy teacher at Herndon High School -- one of only six American teachers selected to work with scientists aboard SOFIA and to share that experience with their students. I know you are all eager to tour this magnificent aircraft, so I am only going to speak briefly then turn it over to my colleagues, Paul Hertz, NASA’s Chief Scientist in our Science Mission Directorate; and Leland Melvin, our Associate Administrator for Education and a former astronaut. Paul and Leland will speak more about the amazing scientific and educational value of SOFIA, but let me just tell you that this project is a key component of NASA’s science objectives. 2 It will help us zoom in close on some of the most fundamental questions of the universe: Where did we come from? How was our solar system formed? And what else is out there? It is fitting that SOFIA means “wisdom” in Greek. -
The Influence of Space Power Upon History (1944-1998)*
* The Influence of Space Power upon History (1944-1998) by Captain John Shaw, USAF * My interest in this subject grew during my experiences as an Air Force Intern 1997-98, working in both the Office of the Deputy Undersecretary of Defense for Space, and in SAF/AQ, Space and Nuclear Deterrence Directorate. I owe thanks to Mr. Gil Klinger (acting DUSD(Space)) and BGen James Beale (SAF/AQS) for their advice and guidance during my internships. Thanks also to Mr. John Landon, Col Michael Mantz, Col James Warner, Lt Col Robert Fisher, and Lt Col David Spataro. Special thanks to Col Simon P. Worden for his insight on this topic. A primary task of the historian is to interpret events in the course of history through a unique lens, affording the scholar a new, and more intellectually useful, understanding of historical outcomes. This is precisely what Alfred Thayer Mahan achieved when he wrote his tour de force The Influence of Sea Power upon History (1660-1783). He interpreted the ebb and flow of national power in terms of naval power, and his conclusions on the necessity of sea control to guarantee national welfare led many governments of his time to expand their naval capabilities. When Mahan published his work in 1890, naval power had for centuries already been a central determinant of national military power.1 It remained so until joined, even eclipsed, by airpower in this century. Space, by contrast, was still the subject of extreme fiction a mere one hundred years ago, when Jules Verne’s From the Earth to the Moon and H.G. -
