This book was released on 2018-05-20 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lunar Roving Vehicle (LRV) was developed for NASA s Apollo program so astronauts could cover a greater range on the lunar surface, carry more science instruments, and return more soil and rock samples than by foot. Because of the unique lunar environment, the creation of flexible wheels was the most challenging and time consuming aspect of the LRV development. Wheels developed for previous lunar systems were not sufficient for use with this manned vehicle; therefore, several new designs were created and tested. Based on criteria set by NASA, the choices were narrowed down to two: the wire mesh wheel developed by General Motors (GM), and the hoop spring wheel developed by the Bendix Corporation. Each of these underwent intensive mechanical, material, and terramechanical analyses, and in the end, the wire mesh wheel was chosen for the LRV. Though the wire mesh wheel was determined to be the best choice for its particular application, it may be insufficient towards achieving the objectives of future lunar missions that could require higher tractive capability, increased weight capacity, or extended life. Therefore lessons learned from the original LRV wheel development and suggestions for future Moon wheel projects are offered.

Book excerpt: "THRILLING. ... Up-end[s] the Apollo narrative entirely." —The Times (London) A "brilliantly observed" (Newsweek) and "endlessly fascinating" (WSJ) rediscovery of the final Apollo moon landings, revealing why these extraordinary yet overshadowed missions—distinguished by the use of the revolutionary lunar roving vehicle—deserve to be celebrated as the pinnacle of human adventure and exploration. One of The Wall Street Journal's 10 Best Books of the Month 8:36 P.M. EST, December 12, 1972: Apollo 17 astronauts Gene Cernan and Jack Schmitt braked to a stop alongside Nansen Crater, keenly aware that they were far, far from home. They had flown nearly a quarter-million miles to the man in the moon’s left eye, landed at its edge, and then driven five miles in to this desolate, boulder-strewn landscape. As they gathered samples, they strode at the outermost edge of mankind’s travels. This place, this moment, marked the extreme of exploration for a species born to wander. A few feet away sat the machine that made the achievement possible: an electric go-cart that folded like a business letter, weighed less than eighty pounds in the moon’s reduced gravity, and muscled its way up mountains, around craters, and over undulating plains on America’s last three ventures to the lunar surface. In the decades since, the exploits of the astronauts on those final expeditions have dimmed in the shadow cast by the first moon landing. But Apollo 11 was but a prelude to what came later: while Neil Armstrong and Buzz Aldrin trod a sliver of flat lunar desert smaller than a football field, Apollos 15, 16, and 17 each commanded a mountainous area the size of Manhattan. All told, their crews traveled fifty-six miles, and brought deep science and a far more swashbuckling style of exploration to the moon. And they triumphed for one very American reason: they drove. In this fast-moving history of the rover and the adventures it ignited, Earl Swift puts the reader alongside the men who dreamed of driving on the moon and designed and built the vehicle, troubleshot its flaws, and drove it on the moon’s surface. Finally shining a deserved spotlight on these overlooked characters and the missions they created, Across the Airless Wilds is a celebration of human genius, perseverance, and daring.

Download or read book Mobility Performance of the Lunar Roving Vehicle written by Nicholas C. Costes and published by . This book was released on 1972 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The constraints of the Apollo 15 mission dictated that the average and limiting performance capabilities of the first manned Lunar Roving Vehicle, when operated on the lunar vehicle, be known or estimated within narrow margins. For this reason, extensive studies were conducted during the year preceding the Apollo 15 launch and are described herein. The results of these studies are compared with the actual performance of the Lunar Roving Vehicle during the Apollo 15 mission. From this comparison, conclusions are drawn relating to the capabilities and limitations of current terrestrial methodology in predicting the mobility performance of lunar roving vehicles under in-situ environmental conditions, and recommendations are offered concerning the performance of surface vehicles on future missions related to lunar or planetary exploration.

Download or read book Apollo Lunar Roving Vehicle Operations Handbook written by Nasa and published by Periscope Film LLC. This book was released on 2012 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developed in only 17 months at a cost of 38 million dollars, the Lunar Roving Vehicle (LRV) greatly expanded the survey range of the astronauts on Apollo 15, 16 and 17. Designed to operate in the low-gravity vacuum of the Moon, the LRV boasted an ingenious design that allowed it to be folded up and stored inside the Lunar Module. It would then be deployed using a system of pulleys and brake reels. The LRV's frame was made of aluminum alloy 2219 tubing assemblies, giving the vehicle a fairly small mass of 210kg but allowing it to carry up to 490kg on the lunar surface. The LRV's lightweight tires were made of zinc-coated steel strands with titanium chevrons and aluminum hubs, and offered a ground clearance of 36cm. The LRV featured two side-by-side, foldable seats, a TV camera, and a dish antenna. Four independent DC motors - one for each wheel - powered by two 36-volt batteries provided maneuvering power. Both sets of wheels could be used to steer, although they could also be decoupled. For safety reasons, astronauts never drove the LRV a distance farther from the LM than they could safely walk in the unlikely event that the rover failed. On each of the three day missions that it was employed, the LRV was used daily for three traverses. The longest was on Apollo 17, when it was driven 20.1km, and it traveled a total of 35.9km on that mission. The total distance traveled by all three LRVs was 90.4km. Almost all of it was done without incident, although some damage to the fender extensions caused dust problems on Apollo 16 and 17. Harrison Schmitt of Apollo 17 praised the design and operation of the vehicle, saying "...the Lunar Rover proved to be the reliable, safe and flexible lunar exploration vehicle we expected it to be." Originally created for the astronauts by prime contractor Boeing, this Lunar Roving Vehicle Operations Handbook describes the LRV and its systems, and details the deployment and driving procedures. It also details the 1-gravity LRV used to train astronauts on Earth. A lengthy appendix provides performance and other data.

Download or read book Early Exploration of the Moon written by Tom Lund and published by Springer. This book was released on 2018-12-26 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Luna 2, launched by the USSR in 1959, was the first spacecraft from Earth to land on the moon. That first voyage was followed by increasingly capable lunar exploration spacecraft from Russia and the United States. A total of 36 successful lunar exploration missions were conducted from 1959 to the last Apollo manned exploration in 1972 and the final travels of the Lunokhod lunar rover in 1973. Of all the missions, that of Apollo 17 was the pinnacle of manned space exploration. Apollo 17 astronauts traveled 21 miles on the lunar surface in a dune buggy-type vehicle, stopping frequently to explore and gather samples. The spacecraft that enabled lunar exploration were ingenious, and reflected the best efforts of talented people working with the technology of the day. This book showcases the engineering involved in those incredible machines. The spacecraft covered, and their missions, are listed below. From the United States: • Ranger – Photography en route to lunar impact • Lunar Orbiter – Photography of front and back side of moon • Surveyor – Soft landing, photography, and soil analysis • Apollo – Manned exploration. Lunar Rover expanded range From the USSR: • Luna 2 – Photography en route to lunar impact • Luna 3 – Photography of back side of moon on flyby • Luna 9 and 13 – Soft landing, photography, and soil analysis • Luna 10, 11, 12, 14 – Photography from lunar orbit • Luna 16, 20, 24 – Soft landing, return of soil sample to Earth • Lunokhod-1, -2 – Lunar roving vehicle driven from Earth • L1 – Planned manned lunar flyby but only flew unmanned • L3 – Planned manned lunar landing but never flew to moon To tell the story of these spacecraft, Tom Lund draws on over 40 years’ work on aircraft and spacecraft systems. He was technical lead for the landing radars for the Surveyor and Apollo spacecraft, and his practical experience is augmented by master’s degrees in electrical engineering, physics, and business administration.

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 394 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 The Saturn V F 1 Engine written by Anthony Young and published by Springer Science & Business Media. This book was released on 2008-11-25 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: The launch of Sputnik in 1957 not only began the space age, it also showed that Soviet rockets were more powerful than American ones. Within months, the US Air Force hired Rocketdyne for a feasibility study of an engine capable of delivering at least 1 million pounds of thrust. Later, NASA ran the development of this F-1 engine in order to use it to power the first stage of the Saturn V rocket that would send Apollo missions to the Moon. It is no exaggeration to say that without the F-1 engine NASA would not have been able to achieve President Kennedy’s 1961 challenge to his nation to land a man on the Moon before the decade was out.
