The Mars Science Laboratory Mission

Within the Office of Space Science of the National Aeronautics and Space Administration (NASA) special importance is attached to exploration of the planet Mars, because it is the most like Earth of the planets in the solar system and the place where the first detection of extraterrestrial life seems most likely to be made. The failures in 1999 of two NASA missions-Mars Climate Orbiter and Mars Polar Lander-caused the space agency's program of Mars exploration to be systematically rethought, both technologically and scientifically. A new Mars Exploration Program plan (summarized in Appendix A) was announced in October 2000. The Committee on Planetary and Lunar Exploration (COMPLEX), a standing committee of the Space Studies Board of the National Research Council, was asked to examine the scientific content of this new program. This goals of this report are the following: -Review the state of knowledge of the planet Mars, with special emphasis on findings of the most recent Mars missions and related research activities; -Review the most important Mars research opportunities in the immediate future; -Review scientific priorities for the exploration of Mars identified by COMPLEX (and other scientific advisory groups) and their motivation, and consider the degree to which recent discoveries suggest a reordering of priorities; and -Assess the congruence between NASA's evolving Mars Exploration Program plan and these recommended priorities, and suggest any adjustments that might be warranted.

This book describes the most complex machine ever sent to another planet: Curiosity. It is a one-ton robot with two brains, seventeen cameras, six wheels, nuclear power, and a laser beam on its head. No one human understands how all of its systems and instruments work. This essential reference to the Curiosity mission explains the engineering behind every system on the rover, from its rocket-powered jetpack to its radioisotope thermoelectric generator to its fiendishly complex sample handling system. Its lavishly illustrated text explains how all the instruments work -- its cameras, spectrometers, sample-cooking oven, and weather station -- and describes the instruments' abilities and limitations. It tells you how the systems have functioned on Mars, and how scientists and engineers have worked around problems developed on a faraway planet: holey wheels and broken focus lasers. And it explains the grueling mission operations schedule that keeps the rover working day in and day out.

The story of the people who designed, built, launched, landed, and are now operating the Mars rover Curiosity Award-winning science writer Rod Pyle provides a behind-the-scenes look into the recent space mission to Mars of Curiosity--the unmanned rover that is now providing researchers with unprecedented information about the red planet. Pyle follows the team of dedicated scientists whose job it is to explore new vistas on Mars. Readers will also join Curiosity, the most advanced machine ever sent to another planet, on its journey of discovery. Drawing on his contacts at NASA and the Jet Propulsion Laboratory, the author provides stunning insights into how this enthusiastic team of diverse individuals uses a revolutionary onboard laboratory of chemistry, geology, and physics instruments to unravel the profound secrets of the Red Planet. Readers will meet: Robert Manning, chief engineer for every rover mission since Pathfinder; John Grotzinger, the chief scientist of the entire mission; Vandi Tompkins, the software designer who keeps the rover on track; Bobak Ferdowsi, famed “Mohawk Guy” from Mission Control; Adam Steltzner, the Elvis-like Entry, Descent and Landing Lead; Al Chen, chief of flight dynamics and the voice of JPL during Curiosity’s treacherous landing; and many others. And of course, Pyle describes the adventures of the Curiosity rover itself, from landing through the first samples, drilling, and discovering a habitable past on the planet, to reaching the ultimate target: Mount Sharp, in the center of Gale Crater. America is once again at the forefront of a new space age and Curiosity is just the beginning of many exciting new discoveries to come.

Could life have previously flourished on Mars? Will humans be able to travel there one day? Can humans one day colonize the red planet? NASA scientists have been interested in answering questions like these for a long time. In November 2011, NASA sent the rover Curiosity to Earth's nearest planetary neighbor. By gathering information about Mars's climate and geology, the robot is helping scientists uncover the secrets of the planet and its past. Since its launch, Curiosity has made some amazing discoveries. The rover found an ancient streambed where water once flowed for thousands of years, and rock samples proved that the surface soil on Mars still has water! In addition, from drilling into Martian rock, the rover detected the key chemicals necessary for life?sulfur, nitrogen, hydrogen, oxygen, phosphorus, and carbon. And Curiosity's measurement of radiation on Mars shows levels similar to that at the International Space Station. These discoveries suggest that some parts of Mars could have been habitable?and may be again in the future. Learn more about the red planet and see what else Curiosity has uncovered!

The Mars Curiosity Rover is the most sophisticated mobile laboratory ever deployed on a planet. For over seven years, scores of investigators have planned its daily route and activities, poring over the overwhelming images and data and revising our understanding of planetary surfaces, geology, and potential habitability. This book takes readers right down to the surface of Mars, chronicling Curiosity’s physical and scientific journey across the planet’s Earth-like, yet strikingly alien vistas. Through dozens of images and descriptive accounts of the surface, you will gain a deeper knowledge of the Martian landscape, from the floor of Gale Crater up to the cliffs of Mount Sharp. Presented at the end of each chapter are the results and revelations from the science team spearheading the mission. Like any cross-country road trip, the rover has hit some unexpected hitches along the way. The book describes the obstacles faced by the rover and its scientists over the years and the difficult decisions and careful experimentation it took to solve them.

The Red Planet has been a subject of fascination for humanity for thousands of years, becoming part of our folklore and popular culture. The most Earthlike of the planets in our solar system, Mars may have harbored some form of life in the past and may still possess an ecosystem in some underground refuge. The mysteries of this fourth planet from our Sun make it of central importance to NASA and its science goals for the twenty-first century.ÊÊ In the wake of the very public failures of the Mars Polar Lander and the Mars Climate Orbiter in 1999, NASA embarked on a complete reassessment of the Mars Program. Scott Hubbard was asked to lead this restructuring in 2000, becoming known as the "Mars Czar." His team's efforts resulted in a very successful decade-long series of missions--each building on the accomplishments of those before it--that adhered to the science adage "follow the water" when debating how to proceed. Hubbard's work created the Mars Odyssey mission, the twin rovers Spirit and Opportunity, the Mars Reconnaissance Orbiter, the Phoenix mission, and most recently the planned launch of the Mars Science Laboratory.Ê Now for the first time Scott Hubbard tells the complete story of how he fashioned this program, describing both the technical and political forces involved and bringing to life the national and international cast of characters engaged in this monumental endeavor.Ê Blending the exciting stories of the missions with the thrills of scientific discovery, Exploring Mars will intrigue anyone interested in the science, the engineering, or the policy of investigating other worlds.

The Mars Science Laboratory is the latest and most advanced NASA roving vehicle to explore the surface of Mars. The Curiosity rover has landed in Gale crater and will explore this region assessing conditions on the surface that might be hospitable to life and paving the way for later even more sophisticated exploration of the surface. This book describes the mission, its exploration and scientific objectives, studies leading to the design of the mission and the instruments that accomplish the objectives of the mission. This book is aimed at all those engaged in Martian studies as well as those interested in the origin of life in other environments. It will be a valuable reference for anyone who uses data from the Mars Science Laboratory. Previously published in Space Science Reviews journal, Vol. 170/1-4, 2012.
