From a long-term planning lead for the Mars Exploration Rover Project comes this vivid insider account of some of NASA’s most vital and exciting missions to the Red Planet, illustrated with full-colour photographs—a wondrous chronicle of unprecedented scientific discovery and the search for evidence of life on Mars.

In this book, Donald Rapp looks at human missions to Mars from a technological perspective. He divides the mission into a number of stages: Earth’s surface to low-Earth orbit (LEO); departing from LEO toward Mars; Mars orbit insertion and entry, descent and landing; ascent from Mars; trans-Earth injection from Mars orbit and Earth return. A mission to send humans to explore the surface of Mars has been the ultimate goal of planetary exploration since the 1950s, when von Braun conjectured a flotilla of 10 interplanetary vessels carrying a crew of at least 70 humans. Since then, more than 1,000 studies were carried out. This third edition provides extensive updating and additions to the last edition, including new sections, and many new figures and tables, and references.

A scientist with the Jet Propulsion Laboratory offers an inside look at the future of manned missions to Mars, tracing the history of Mars exploration and shedding new light on the future directions of expeditions to the Red Planet.

Can astronauts reach Mars by 2035? Absolutely, says Buzz Aldrin, one of the first men to walk on the moon. Celebrated astronaut, brilliant engineer, bestselling author, Aldrin believes it is not only possibly but vital to America's future to keep pushing the space frontier outward for the sake of exploration, science, development, commerce, and security. What we need, he argues, is a commitment by the U.S. President as rousing as JFK's promise to reach the moon by the end of the 1960 - an audacious, inspiring goal-and a unified vision for space exploration. In Mission to Mars, Aldrin plots that trajectory, stressing that American-led space exploration is essential to the economic and technological vitality of the nation and the world. Do you dare to dream big? Then join Aldrin in his thought provoking and inspiring Mission to Mars.

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.

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!

This is the comprehensive story of NASA’s pioneering Mars 2020 mission, which at this moment continues to break ground on the surface of the Red Planet. The book takes readers through every stage of the Mars mission, describing its major goals and objectives, the cutting-edge technology and instrumentation onboard the Perseverance rover and other spacecraft components, and the members of the scientific team who steered the mission along the way. Mars 2020 is the first to actually take samples of the Red Planet and prepare them for subsequent return to Earth. The chapters therefore delve into how and why Jezero Crater was selected as the optimal landing and sample collecting site to meet the mission objectives. Featuring dozens of high-resolution images of the mission, this book gives readers a deeper understanding of the technology underlying Mars 2020 and why its work is so important for planetary science and space exploration.
