Mercury Mars And Other Inner Planets

Examines the surface, atmosphere, and characteristics of the inner planets, and discusses how they are explored and studied.

Despite their proximity to Earth, much remains to be learned about the origins and conditions of Mercury, Venus, and Mars. The three smallest planets in our solar system and the three closest to the Sun—Mercury, Venus, and Mars—differ greatly from each other and from the place we call home. This far-reaching volume travels to each of the inner planets in turn and details the physical characteristics as well as the exploration efforts made in order to learn more about our closest planetary neighbors.

In recent years, planetary science has seen a tremendous growth in new knowledge. Deposits of water ice exist at the Moon's poles. Discoveries on the surface of Mars point to an early warm wet climate, and perhaps conditions under which life could have emerged. Liquid methane rain falls on Saturn's moon Titan, creating rivers, lakes, and geologic landscapes with uncanny resemblances to Earth's. Vision and Voyages for Planetary Science in the Decade 2013-2022 surveys the current state of knowledge of the solar system and recommends a suite of planetary science flagship missions for the decade 2013-2022 that could provide a steady stream of important new discoveries about the solar system. Research priorities defined in the report were selected through a rigorous review that included input from five expert panels. NASA's highest priority large mission should be the Mars Astrobiology Explorer Cacher (MAX-C), a mission to Mars that could help determine whether the planet ever supported life and could also help answer questions about its geologic and climatic history. Other projects should include a mission to Jupiter's icy moon Europa and its subsurface ocean, and the Uranus Orbiter and Probe mission to investigate that planet's interior structure, atmosphere, and composition. For medium-size missions, Vision and Voyages for Planetary Science in the Decade 2013-2022 recommends that NASA select two new missions to be included in its New Frontiers program, which explores the solar system with frequent, mid-size spacecraft missions. If NASA cannot stay within budget for any of these proposed flagship projects, it should focus on smaller, less expensive missions first. Vision and Voyages for Planetary Science in the Decade 2013-2022 suggests that the National Science Foundation expand its funding for existing laboratories and establish new facilities as needed. It also recommends that the program enlist the participation of international partners. This report is a vital resource for government agencies supporting space science, the planetary science community, and the public.

"America keeps a fine house," Anatol Lieven writes, "but in its cellar there lives a demon, whose name is nationalism." In this controversial critique of America's role in the world, Lieven contends that U.S. foreign policy since 9/11 has been shaped by the special character of our national identity, which embraces two contradictory features. One, "The American Creed," is a civic nationalism which espouses liberty, democracy, and the rule of law. It is our greatest legacy to the world. But our almost religious belief in the "Creed" creates a tendency toward a dangerously "messianic" element in American nationalism, the desire to extend American values and American democracy to the whole world, irrespective of the needs and desires of others. The other feature, populist (or what is sometimes called "Jacksonian") nationalism, has its roots in an aggrieved, embittered, and defensive White America, centered largely in the American South. Where the "Creed" is optimistic and triumphalist, Jacksonian nationalism is fed by a profound pessimism and a sense of personal, social, religious, and sectional defeat. Lieven examines how these two antithetical impulses have played out in recent US policy, especially in the Middle East and in the nature of U.S. support for Israel. He suggests that in this region, the uneasy combination of policies based on two contradictory traditions have gravely undermined U.S. credibility and complicated the war against terrorism. It has never been more vital that Americans understand our national character. This hard-hitting critique directs a spotlight on the American political soul and on the curious mixture of chauvinism and idealism that has driven the Bush administration.

The inner planets, Mercury, Venus, Earth and Mars, are important for study because they are so similar. All are terrestrial, meaning they have a solid surface. Mercury, being closest to the Sun, experiences the most intense solar radiation. Venus is an example of an extreme greenhouse environment, with temperatures nearing 1,000 degrees Fahrenheit. Mars offers us great hope for finding an environment that could have harbored extraterrestrial life. This book follows the Next Generation Science Standards focusing on the Earth and the solar system and shows readers that we can learn a lot about our own planet from our celestial neighbors.

Stargazers have observed Mercury, Venus, and Mars—the other small, rocky planets in our solar system besides Earth—for thousands of years. More recently, we have begun to explore our neighbors in outer space via flyby spacecraft, probes, and rovers. Readers will learn how these expeditions have expanded our knowledge of these planets’ atmospheres, surfaces, features, and even potential for life. A must-read for anyone interested in discovering more about space exploration’s past, present, and future.

Take a journey around the solar system's inner planets and find out about the space race that is going on between countries to have the first humans to reach them. Learn all about Mars, Venus and the other planets and discover the incredible technology behind how we know about them.

Presents an introduction to the solar system, focusing on the Sun and the four planets closest to it, along with information about the Earth's Moon and lunar and solar eclipses.
