Recent spacecraft and robotic probes to Mars have yielded data that are changing our understanding significantly about the possibility of existing or past life on that planet. Coupled with advances in biology and life-detection techniques, these developments place increasing importance on the need to protect Mars from contamination by Earth-borne organisms. To help with this effort, NASA requested that the NRC examine existing planetary protection measures for Mars and recommend changes and further research to improve such measures. This report discusses policies, requirements, and techniques to protect Mars from organisms originating on Earth that could interfere with scientific investigations. It provides recommendations on cleanliness and biological burden levels of Mars-bound spacecraft, methods to reach those levels, and research to reduce uncertainties in preventing forward contamination of Mars.

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.

The Space Studies Board of the National Research Council (NRC) serves as the primary adviser to the National Aeronautics and Space Administration (NASA) on planetary protection policy, the purpose of which is to preserve conditions for future biological and organic exploration of planets and other solar system objects and to protect Earth and its biosphere from potential extraterrestrial sources of contamination. In October 1995 the NRC received a letter from NASA requesting that the Space Studies Board examine and provide advice on planetary protection issues related to possible sample-return missions to near-Earth solar system bodies.

The next frontier in space exploration is Mars, the red planet--and human habitation of Mars isn't much farther off. Now the National Geographic Channel goes years fast-forward with "Mars," a six-part series documenting and dramatizing the next 25 years as humans land on and learn to live on Mars. This companion book to the series explores the science behind the mission and the challenges awaiting those brave individuals. Filled with vivid photographs taken on Earth, in space, and on Mars; arresting maps; and commentary from the world's top planetary scientists, this fascinating book will take you millions of miles away--and decades into the future--to our next home in the solar system.

Two scenarios for accomplishing a Mars Sample Return mission are presented herein. Mission A is a low cost, low mass scenario, while Mission B is a high technology, high science alternative. Mission A begins with the launch of one Titan IV rocket with a Centaur G' upper stage. The Centaur performs the trans-Mars injection burn and is then released. The payload consists of two lander packages and the Orbital Transfer Vehicle, which is responsible for supporting the landers during launch and interplanetary cruise. After descending to the surface, the landers deploy small, local rovers to collect samples. Mission B starts with 4 Titan IV launches, used to place the parts of the Planetary Transfer Vehicle (PTV) into orbit. The fourth launch payload is able to move to assemble the entire vehicle by simple docking routines. Once complete, the PTV begins a low thrust trajectory out from low Earth orbit, through interplanetary space, and into low Martian orbit. It deploys a communication satellite into a 1/2 sol orbit and then releases the lander package at 500 km altitude. The lander package contains the lander, the Mars Ascent Vehicle (MAV), two lighter than air rovers (called Aereons), and one conventional land rover. The entire package is contained with a biconic aeroshell. After release from the PTV, the lander package descends to the surface, where all three rovers are released to collect samples and map the terrain.
