    “By prevailing over all obstacles and distractions, one may unfailingly arrive at his chosen goal or destination” a quote by Christopher Columbus explains how he felt after his technology failed him by leading him in the Americas and not Asia according to his plan. Christopher Columbus took part in the "Age of Discovery", which was a time during the 15th and 16th century when European leaders, starting with Portugal, sponsored the expeditions to undiscovered land in hopes of expanding their wealth and land. Christopher Columbus believed he could reach Asia by sailing across the Atlantic instead, his idea received the sponsorship and he began his journey on August 3, 1492. Christopher Columbus used many forms of technology such as maps, charts and magnetic compasses on his journeys to know where he was he also used sand glasses to keep track of time. Although he used these tools there are modern technologies today that would have been a great benefit to him and his crew. Today 's technology is advanced and will only continue to do so, however, I believe that a Global Positioning System (GPS), modern medicine, and a gas powered boat would have been the most beneficial to Christopher Columbus. In today 's society, most people have some type of GPS, either in their car or on their phone, and in all honestly if you asked many of them to use a map, they would be confused on how to read it or become lost quickly. With that in mind, I believe Cristopher Columbus had a great need…

    following information: • Speed • Bearing • Track • Trip distance • Distance to destination • Sunrise and sunset time • And more Almanac and Ephemeris To figure out the location of the GPS satellites two types of data are required by the GPS receiver: the almanac and the ephemeris. This data is continuously transmitted by the GPS satellites and the receiver collects and stores this data. The almanac contains information about the status of the satellites and approximate orbital information. The…

    Even the smallest of differences in initial states will grow over time when numerically integrated. From our experience in operating LEO satellites for NASA, we use much shorter state propagation times, which helps OD results stay more accurate. For example, it is common for missions to compute 7-day ephemeris files on a daily basis to ensure overlapping data in the ephemeris throughout the mission. Then, once a month, compute a 4-6 week ephemeris for science planning purposes. This helps keep…

    Jones Point in Alexandria, VA to ascertain the location of the starting point for the survey. Also during this time he maintained a clock that he used to regulate points on the ground to the positions of the stars at specific times. However three months later he left the boundary due to illness, and difficulties completing the survey at the age of 59. At that point he returned home to work on an ephemeris. An ephemeris is a something that is used to map out starts. Banneker was later able to…

    calculations, and when a higher understanding of math is needed, astrologers often look at past findings from astronomers. These two different sciences require a wide range of tools to practice them. To study astronomy, one must employ the use of telescopes, aircraft and spacecraft, computers, a variety of cameras, and spectrographs; each one of these tools serves a specific role when practicing astronomy. The telescope, for example, can help determine details far further than a human's eye…

    Some previous works on Lincoln Foner mentions are the Memorial Lincoln Biography , which listed books, eulogies, sermons and ephemeris (prefacexv) , The Collected Works of Abraham Lincoln ,which contained mostly speeches and war time directives. (Foner preface xvi) The reason Foner feels there is a need for his book within the scholarship is because we should try to understand Lincoln from the beginning moving forward, as his growth unfolded, through one experience after another, not trying to…

When a Quaker School was built nearby, Benjamin tried to convince his parents to let him attend. They eventually agreed that he could attend in the winter time. For three years from then, he attended school every winter and taught himself the remaining subjects during the other three seasons of the year. When he was only 22 he invented a wooden clock that kept accurate time…

    will be written in the form of (r1, θ1) and the position of mars at landing will be stated as (r2, θ2) The equation of an ellipse: r=p/(1+e cos⁡θ ) However, we cannot assume that all ellipses are rectangular. There are some orbits that are inclined by an angle, . For those ellipses the equation changes to: Equation of the trajectory: The true anomaly is the polar coordinate equation of the ellipse that links r, and e. Its equation is: r=(a(1-e^2))/(1+e cos⁡θ ) Where a is the semi…
