Special Relativity problem?
Muons are subatomic particles that are produced several miles above the earth’s surface as a result of collisions of cosmic rays (charged particles, such as protons, that enter the earth’s atmosphere from space) with atoms in the atmosphere. These muons rain down more-or-less uniformly on the ground, although some of them decay on the way since the muon is unstable with proper half-life of about 1.5 μs. In a certain experiment a muon detector is carried in a balloon to an altitude of 2000 m, and in the course of 1 hour it registers 650 muons traveling at 0.99c toward the earth. If an identical detector remains at sea level, how many muons would you expect it to register in 1 hour? (Remember that after n half-lives the number of muons surviving from an initial sample of N0 is N0/2n, and don’t forget about time dilation.)
I set up the problem as No/2^(halflife per time)(t’) but im getting a number thats too small for my calculator
Either calculate the distance in the muon’s frame, or calculate the muon’s moving halflife (what is gamma for 0.99?).
Then apply the halflife formula
E = E_o*(1/2)^(time/halflife)

Roving MARS $36.95 “Visually Stunning” – Ann Hornaday, Washington Post Mars is Earth’s closest planetary neighbor, and for decades scientists have been curious about the so-called “Red Planet,” wondering if it’s possible that life exists there, how its soil and terrain differs from our own, and if water can be found. While sending a manned space mission to Mars has been considered beyond the reach of America’s space program, in 2001 the National Aeronautics and Space Administration approved a mission to send two “rovers” to Mars — wheeled robots that would send images and data back to Earth. A two-year crash program resulted in two robotic rovers (dubbed “Spirit” and “Opportunity”) being sent to Mars, which have given scientists and researchers on Earth a brand new vision of what the planet is really like. Roving Mars is a documentary which offers a detailed look at the people behind the Mars rover program, how the machines were built and what they can do, and what has been learned since they reached their target. Roving Mars was shot and originally exhibited in the high-definition IMAX film format. ~ Mark Deming, All Movie Guide Features: Actors: Paul Newman, Stephen Squyres, Rob Manning (IV), Charles Elachi, Wayne Lee (II) Directors: George Butler (II) Format: AC-3, Closed-captioned, Color, Dolby, Dubbed, DVD-Video, Full Screen, Subtitled, Widescreen, NTSC Language: English Aspect Ratio: 1.78:1 Studio: Buena Vista Home Entertainment DVD Release Date: July 31, 2007 Run Time: 40 minutes Bonus Features: Bonus Movie: Mars and Beyond – Walt Disney’s 1957 Investigation into the mysteries of the universe and space travel. 50 minutes. “Mars: Past, Present & Future”- Personal reflections on Mars from the filmmakers, JPL Rover team members and students from the “Imagine Mars” program |

Gemini Spacecraft Replica $259 Gemini Spacecraft 1/48 Scale Replica Project Gemini was the second human spaceflight program of the United States of America. It operated between Projects Mercury and Apollo, during the years 1963-1966. Its objective was to develop techniques for advanced space travel, notably those necessary for Project Apollo, whose objective was to land men on the Moon. Gemini missions involved extravehicular activity and orbital maneuvers including rendezvous and docking.The Gemini Program was conceived after it became evident to NASA officials that an intermediate step was required between the projects Mercury and Apollo. The major objectives assigned to Gemini were: To subject two men and supporting equipment to long-duration flights, a requirement for projected later trips to the Moon or deeper space. To effect rendezvous and docking with other orbiting vehicles, and to maneuver the docked vehicles in space, using the propulsion system of the target vehicle for such maneuvers. To perfect methods of reentry and landing the spacecraft at a pre-selected land-landing point. To gain additional information concerning the effects of weightlessness on crew members and to record the physiological reactions of crew members during long-duration flights. After 10 successful flights, the Gemini program clearly placed the United States in the lead over the Soviet Union in manned spaceflight. The flight of Gemini VIII included the successful emergency recovery of the tumbling orbiting capsule by Neil ArmstrongThis Gemini Spacecraft 1/48 Scale Replica is by expert modeler Nick Proach.

First Man: The Life of Neil A. Armstrong (Paperback) $17.95 First Man: The Life of Neil A. Armstrong Neil Armstrong will always be remembered for being the first man to step on the moon, a milestone that played a role in everything he did afterward. Through most of this biography, which follows Armstrong from his youth to that historic lunar landing, Boyd Gaines reads with detachment, letting the facts of Armstrong’s life speak for themselves–and those facts speak beautifully. On July 20, 1969, a quiet, determined man from Wapakoneta, Ohio, stepped out of his fragile spacecraft and into history. Neil Armstrong–engineer, naval aviator, test pilot, astronaut and devoted family man–became the first man to walk on the moon. In this powerful, unrelenting biography of a man of no particularly spectacular talent yet who stands as a living testimony to everyday grit and determination, former NASA historian Hansen has achieved something quite remarkable. Like a rich pointillist painting, he has created a magnificent panorama of the second half of the American 20th century by assembling a multitude of luminescent moments in one man’s life. From Armstrong’s birth to a middle-class family in Ohio to the mind-boggling fame of the Apollo 11 triumph, and later his service on the commission investigating the 1986 Challenger space shuttle disaster, Hansen details it all. He writes of the number of rounds of 20-millimeter ammunition loosed by Armstrong’s fighter squadron in Korea in October 1951 (49,299)and his heart rate on liftoff in Gemini VIII (146 beats per minute) Rather than overwhelming, this accumulation of details gives flesh-and-blood reality to a man who is more icon than human. With the recent renewal of interest in manned space travel, this book is a must for astronaut buffs and history readers alike. Features and Reviews: “If you think you know everything about Neil Armstrong and America’s historic mission…First Man contributes a host of fascinating new insights into the nature of spacefaring enterprise itself. A book for all time” – Walter Cronkite Paperback: 784 pages Publisher: Simon & Schuster; Reprint edition (October 3, 2006) Language: English Product Dimensions: 9.1 x 6.1 x 1.5 inches |

Upon approaching the moon, the spacecraft was oriented with the service propulsion engine facing in the direction of travel. Communication with Earth was temporarily interrupted as the spacecraft swung around the far side of the moon. On their own, the crew performed the complicated procedure which fired the engine for a little over 4 minutes thereby slowing the speed of the spacecraft just enough to place it into lunar orbit. This was a critical maneuver and everyone was more than just a little tense as the engine had never been tested in lunar orbit before this mission. Any malfunctions or deviation in burn time could have lead to disastrous consequences.. Jim Lovell later stated it was the longest four minutes he had ever spent. Everyone was relieved as the engine performed flawlessly and on Christmas Eve the crew of Bill Anders, Frank Borman and Jim Lovell became the first human beings in history to orbit another celestial body other than the planet earth.

An hour of video and three unique and exclusive hi-resolution Quicktime panoramas of Tranquillity Base never seen before. And as a special bonus a foreword by Dr Buzz Aldrin.Since the first glimmerings of intellect on planet Earth the moon?s quicksilver light has beckoned. In July of 1969 the people of the world were witness to an event, which was the undisputed scientific accomplishment of the 20th century. When astronauts Neil Armstrong and Edwin (Buzz) Aldrin planted their footsteps in the barren dusty powder of the lunar surface they not only fulfilled President John Kennedy?s bold challenge but also mankind?s ancient dream. An accomplishment without parallel, the flight of Apollo 11 stands alone as humanity?s greatest feat of imagination made manifest. Everything about project Apollo was an exercise in superlatives the Saturn V was the largest and most powerful machine ever made by man, wielding an unimaginable seven and a half million pounds of thrust while the Apollo spacecraft was able to travel a half a million miles and function with a precision to match the finest Swiss watch. Standing on the shoulders of generations, Armstrong, Aldrin and Collins heralded the arrival of anew era, an era in which the horizon of mankind?s dreams would be forever shifted.

The Conquest of Space $23.95 The Conquest of Space by David Lasser with a new introduction by Sir Arthur C. ClarkeDavid Lasser stands as one of the least-known but extraordinary pioneers of spaceflight. In 1930 he founded the American Interplanetary Society – the same year he wrote this book – the first book ever written in the English language to address the notion of spaceflight as a serious possibility. This book has not been in print since 1931 and yet it still stands up to scrutiny. The lucid style with which Lasser explains the basic concepts of rocketry make it a delight for anyone to read. Only a handful of errors creep into the text and all of those were based on the best information available at the time. The Conquest of Space is a milestone work of spaceflight literature and was state of the art in 1931. No space enthusiast’s library is complete without it. Here is what Sir Arthur C. Clarke had to say about The Conquest of Space… “My encounter with The Conquest of Space, soon after its publication in 1931, was one of the turning points in my life, and I suspect, not only of mine�” FEATURES: Hardcover: 192 pages Publisher: Collector’s Guide Publishing Inc (September 1, 2002) Language: English Book Dimensions: 9.8 x 6.8 x 0.9 inches |
