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. -

Consid- ering processes such as sublimation and Jeans escape, we find that CO 2 ice migrates to low latitudes on geologically short (100s–1000 s of years) timescales. Crater morphology and location create a local cold trap inside Wunda, and the slopes of crater walls and a central peak explain the deposit’s annular shape. The high albedo and thermal inertia of CO 2 ice relative to regolith allows deposits 15-m-thick or greater to be stable over the age of the solar system. -

ORF Issue Brief 59 Dr. Rajeswari Pillai Rajagopalan
ORF ISSUE BRIEF OCTOBER 2013 ISSUE BRIEF # 59 Synergies in Space: The Case for an Indian Aerospace Command Dr. Rajeswari Pillai Rajagopalan Introduction he Indian Armed Forces have been mulling over the establishment of an aerospace command for close to a decade now. Over those years, international circumstances and Tgeopolitics relating to outer space have changed, making it imperative for India to make decisions now. Though outer space is part of the global commons, it is increasingly getting appropriated and fenced as powerful States are seen seeking to monopolise space. The growing advanced military space capabilities of some nations, which include the development of their anti-satellite missile capabilities, are also a worrying trend. With much of outer space having been utilised by a small number of great powers and the increasing presence of non-state players in the recent years, even a nominal increase in terms of space activity by some developing countries is leading to issues related to overcrowding and access. In order to protect its interests, India must institutionalise its own strengths in the form of an Aerospace Command. While all the three services are becoming increasingly reliant on outer space assets, the Indian Air Force (IAF) has taken the lead, at least going by open sources. Back in 2003, Indian Air Force Chief Air Marshal S Krishnaswamy had already articulated the need for an aerospace command: “Any country on the fringe of space technology like India has to work towards such a command as advanced countries are already moving towards laser weapon platforms in space and killer satellites.” Some years after that, in 2006, the IAF established a Directorate of Aerospace in Thiruvananthapuram in South India, which can be referred to as the initial avatar of the Indian Observer Research Foundation is a public policy think-tank that aims to influence formulation of policies for building a strong and prosperous India. -

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. -

THE WASHINGTON INSTITUTE FOR NEAR EAST POLICY n AUGUST 2020 n PN84 PHOTO CREDIT: REUTERS © 2020 THE WASHINGTON INSTITUTE FOR NEAR EAST POLICY. ALL RIGHTS RESERVED. FARZIN NADIMI n April 22, 2020, Iran’s Islamic Revolutionary Guard Corps Aerospace Force (IRGC-ASF) Olaunched its first-ever satellite, the Nour-1, into orbit. The launch, conducted from a desert platform near Shahrud, about 210 miles northeast of Tehran, employed Iran’s new Qased (“messenger”) space- launch vehicle (SLV). In broad terms, the launch showed the risks of lifting arms restrictions on Iran, a pursuit in which the Islamic Republic enjoys support from potential arms-trade partners Russia and China. Practically, lifting the embargo could facilitate Iran’s unhindered access to dual-use materials and other components used to produce small satellites with military or even terrorist applications. Beyond this, the IRGC’s emerging military space program proves its ambition to field larger solid-propellant missiles. Britain, France, and Germany—the EU-3 signatories of the Joint Comprehensive Plan of Action, as the 2015 Iran nuclear deal is known—support upholding the arms embargo until 2023. The United States, which has withdrawn from the deal, started a process on August 20, 2020, that could lead to a snapback of all UN sanctions enacted since 2006.1 The IRGC’s Qased space-launch vehicle, shown at the Shahrud site The Qased-1, for its part, succeeded over its three in April. stages in placing the very small Nour-1 satellite in a near circular low earth orbit (LEO) of about 425 km. The first stage involved an off-the-shelf Shahab-3/ Ghadr liquid-fuel missile, although without the warhead section, produced by the Iranian Ministry of Defense.2 According to ASF commander Gen. -
January 2018 Satellite & Space Monthly Review
February 5, 2018 Industry Brief Chris Quilty [email protected] January 2018 +1 (727)-828-7085 Austin Moeller Satellite & Space Monthly Review [email protected] +1 (727)-828-7601 January 11, 2018: Air force to utilize more smallsats for weather DMSP F19 Readying for Launch observation. Citing growing budget constraints, the US Air Force announced that is considering using small satellites in combination with next-gen software rather than procuring traditional multibillion-dollar, cost-plus spacecraft to replace/replenish its Defense Meteorological Satellite Program (DMSP). Despite awarding a $94 million contract to Ball Aerospace in November to design the Weather System Follow-on Microwave (WSF-M) satellite, the Air Force plans to begin launching small satellites equipped with infrared imaging and electro-optical instruments to monitor battlefield weather starting in 2021-2022. The Air Force is also considering augmenting their current capabilities with inactive NOAA GOES satellites in the near-term. These considerations parallel recent comments by USSTRATCOM commander Gen. John Hyten, who has repeatedly stated that the Air Force currently spends too much time and money developing large, high- cost satellites, and needs to invest in more small satellites for strategic Source: Lockheed Martin and budgetary reasons. Conclusion: Smallsats ready for a DoD growth spurt? With growing evidence of Russian/Chinese anti- satellite technology demonstrations, the Pentagon is becoming increasingly reluctant to spend billions of dollars on monolithic “Battlestar Galactica” satellite systems that place too many eggs in one basket. While not as robust or technologically-capable as high-end spacecraft built by traditional contractor, such as Lockheed Martin, small satellites are orders-of-magnitude less expensive to build, launch, and maintain. -

Knox Grammar School STATE DA VINCI DECATHLON 2016 PRACTICE TASKS CELEBRATING THE ACADEMIC GIFTS OF STUDENTS IN YEARS 9, 10 & 11 Task developed by Karen Yager, Knox Grammar School, 2016 An academic gala day for Years 9, 10 & 11 Team Number _____________ Task developed by Karen Yager, Knox Grammar School, 2016 Background information The poet T.S. Eliot wrote “We shall not cease from exploration, and the end of all our exploring will be to arrive where we started and know the place for the first time”. Throughout history humanity has yearned to explore new worlds. However, many after travelling to new places discover that they long to return to their home. They see home in a fresh light and question why they left it in the first place. Homer’s legendary hero Odysseus explored new countries and met fascinating people and creatures but after the tragic loss of all of his men he realised that he wanted to return home to Penelope and the life he led in Ithaca: Many cities of men he saw and learned their minds, many pains he suffered, heartsick on the open sea, fighting to save his life and bring his comrades home. Driven by curiosity many have left home to explore new worlds: the sailors who sailed across unknown, treacherous seas to explore new lands; young country boys who enlisted during the world wars to escape their country homes and explore foreign places; scientists who are planning to travel to Mars knowing that there will be no return; and even many young people who long to leave their home after school and explore new worlds but after extensive travelling discover that their home was a wonderful place.
