Book excerpt: On August 6, 2012 (1:31 AM EDT), the Mars Science Laboratory (MSL) successfully traversed the atmosphere to land on Mars. But by the time the sky crane lowered the Curiosity rover to the surface, one experiment (the MSL Entry Descent and Landing (EDL) Instrumentation (MEDLI) suite) had already collected all of its data. For the entire atmospheric entry phase, from just before atmospheric interface until it was powered off approximately 10 seconds after the parachute was deployed, MEDLI monitored the entry vehicle's surface pressures and heatshield temperatures. MEDLI delivered the first in-depth understanding of the Mars entry environments and the response of the entry vehicle to those environments. Previous Mars entry missions assessed their entry performance (vehicle drag and stability) via the observed initial states coupled with the onboard inertial measurement unit (IMU) data. This approach is devoid of environmental measurements, so total drag force cannot be decomposed into aerodynamics and atmospheric conditions. In addition, no through-thickness measurements to ascertain heatshield thermal protection system (TPS) performance were taken on previous entry missions. MEDLI culminated decades of advocacy by the EDL community for entry vehicle instrumentation. The fate of the Genesis and Stardust sample return missions served as an impetus for this advocacy. On September 8, 2004, an incorrectly installed g-trigger did not command deployment of its drogue chute, and the Genesis capsule tumbled through the atmosphere. The plan had called for a mid-air retrieval via its slow-descent parafoil to avoid landing impact loads, but instead the parafoil did not deploy and the Genesis capsule crashed into the ground. The minimal EDL data available from Genesis also slowed the mishap investigation. Sixteen months later, on January 15, 2006, a successful Stardust return prompted the NASA Administrator to request an assessment of how the vehicle performed. Since the capsule was not instrumented, the ability to quantify vehicle stability and drag performance, as well as the heating environment and the response of the TPS to that environment, was limited. As a result, the Administrator mandated that NASA should instrument all future atmospheric entry systems.

Download or read book Mars Entry Atmospheric Data System Modeling Calibration and Error Analysis written by National Aeronautics and Space Administration and published by Createspace Independent Publishing Platform. This book was released on 2017-01-17 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mars Science Laboratory (MSL) Entry, Descent, and Landing Instrumentation (MEDLI)/Mars Entry Atmospheric Data System (MEADS) project installed seven pressure ports through the MSL Phenolic Impregnated Carbon Ablator (PICA) heatshield to measure heatshield surface pressures during entry. These measured surface pressures are used to generate estimates of atmospheric quantities based on modeled surface pressure distributions. In particular, the quantities to be estimated from the MEADS pressure measurements include the dynamic pressure, angle of attack, and angle of sideslip. This report describes the calibration of the pressure transducers utilized to reconstruct the atmospheric data and associated uncertainty models, pressure modeling and uncertainty analysis, and system performance results. The results indicate that the MEADS pressure measurement system hardware meets the project requirements.

Download or read book The Design and Engineering of Curiosity written by Emily Lakdawalla and published by Springer. This book was released on 2018-03-27 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Destination Mars written by Rod Pyle and published by Prometheus Books. This book was released on 2012-04-24 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the next decade, NASA, by itself and in collaboration with the European Space Agency, is planning a minimum of four separate missions to Mars. Clearly, exciting times are ahead for Mars exploration. This is an insider’s look into the amazing projects now being developed here and abroad to visit the legendary red planet. Drawing on his contacts at NASA and the Jet Propulsion Laboratory, the author provides stunning insights into the history of Mars exploration and the difficulties and dangers of traveling there. After an entertaining survey of the human fascination with Mars over the centuries, the author offers an introduction to the geography, geology, and water processes of the planet. He then briefly describes the many successful missions by NASA and others to that distant world. But failure and frustration also get their due. As the author makes clear, going to Mars is not, and never will be, easy. Later in the book, he describes in detail what each upcoming mission will involve. In the second half of the book, he offers the reader a glimpse inside the world of Earth-based "Mars analogs," places on Earth where scientists are conducting research in hostile environments that are eerily "Martian." Finally, he constructs a probable scenario of a crewed expedition to Mars, so that readers can see how earlier robotic missions and human Earth simulations will fit together. All this is punctuated by numerous firsthand interviews with some of the finest Mars explorers of our day, including Stephen Squyres (Mars Exploration Rover), Bruce Murray (former director of the Jet Propulsion Laboratory), and Peter Smith (chief of the Mars Phoenix Lander and the upcoming OSIRIS-REx missions). These stellar individuals give us an insider’s view of the difficulties and rewards of roaming the red planet. The author’s infectious enthusiasm and firsthand knowledge of the international space industry combine to make a uniquely appealing and accessible book about Mars.

Download or read book Exploring Mars written by Scott Hubbard and published by University of Arizona Press. This book was released on 2012-02-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. 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. 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. 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.
