On the Second Tuesday of Next Week
Suppose you have participated in a great battle at the edge of the Solar System that you believed had been a huge defeat for the invading aliens from the Deneb Star System. But suppose, when you returned to the Combined Headquarters on Mars, everyone believed the battle had been lost. The senior officers told you that, the after-action reports reflected that and the history, as it was written, confirmed that. But you, as on officer who had been there, knew better. This was something that you could not understand. You had seen, with your own eyes, the smashing defeat of the enemy fleet. How do you reconcile that in your mind? Could you be so deluded that you couldn’t face the reality after the sacrifice of so many of your fellow pilots and crew? When all logical answers have been eliminated and there is but a single conclusion left, do you accept it? Did the enemy manipulate the outcome by manipulating time? And if that is the answer, how do you defeat it? They can guarantee the outcome of any battle or any war. If you don’t have the capability to do the same, then the final outcome is a foregone conclusion. But Captain Jack Ellis and a tiny group of scientists might have discovered a way to counteract the enemy advantage. It just requires a small change in human history… BUT, of course, they enemy could always change that too.
Legal Aspects of Planetary Defence
Winner of the 2022 International Academy of Astronautics (IAA) Social Sciences Book Award Impacts by asteroids or comets on Earth may lead to natural disasters of catastrophic dimensions, one of the most devastating having caused the extinction of the dinosaurs 66 million years ago. Space agencies and other actors are increasingly dedicated to the development of technology to predict and mitigate such risks. This book addresses legal and policy aspects of ‘planetary defence’ activities aiming at the mitigation of Near-Earth Objects (NEO) impact threats. These include responsibility and liability for damage caused by such activities (or their failure) as well as international cooperation and possible decision making processes.

The United States spends approximately $4 million each year searching for near-Earth objects (NEOs). The objective is to detect those that may collide with Earth. The majority of this funding supports the operation of several observatories that scan the sky searching for NEOs. This, however, is insufficient in detecting the majority of NEOs that may present a tangible threat to humanity. A significantly smaller amount of funding supports ways to protect the Earth from such a potential collision or "mitigation." In 2005, a Congressional mandate called for NASA to detect 90 percent of NEOs with diameters of 140 meters of greater by 2020. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies identifies the need for detection of objects as small as 30 to 50 meters as these can be highly destructive. The book explores four main types of mitigation including civil defense, "slow push" or "pull" methods, kinetic impactors and nuclear explosions. It also asserts that responding effectively to hazards posed by NEOs requires national and international cooperation. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies is a useful guide for scientists, astronomers, policy makers and engineers.
