Introduction The Mercury-Redstone 3 Freedom 7 was the very first American flight with a human on board. MR-3 had four main objectives while in space. One was to get humans use to a complete space flight experience including the lift-off, powered flight, weightless flight, re-entry, and landing phases. The second objective was to evaluate man's ability to perform as a functional unit during flight. The third thing that MR-3 wanted to achieve was to study man's physiological reactions during space flight.
Explorer 1 had an orbital life cycle of about twelve years, and mission duration of four months. Upon re-entry to earth in 1970, it had completed an astounding 58,000 orbits around the Earth. At the same time as the Vanguard rockets (the satellites proceeding Explorer 1), President Eisenhower and the rest of his cabinet were trying to decide under which agency this new “space” issue fell under the jurisdiction of, to which they found no answer. President Eisenhower instated the National Aeronautics and Space Act which was the creation of the National Aeronautics and Space Administration or more commonly known as NASA. NASA would go on to become the most influential organisation in the world in relation to anything space related.
Introduction One look at the surface of the Moon should convince you that "empty space" is not so empty after all. There is actually a wide range of objects floating between the planets, from tiny particles to asteroids that can be a hundred miles across, debris left behind when the planets were formed. These objects can be perturbed from their orbits (by a close passage by a planet, a passing star, any number of things) and onto paths that cross ours -- or any other planet or moon. When
He built his own telescopes and was the first to use to view the heavens in 1610. After doing so, he made many discoveries. He saw that Jupiter has moon orbiting around it, like the Earth. He made the discoveries of the four moons on January 7, 1610 and they are now called the Galilean moons. These are the largest of Jupiters moons.
12 The space shuttle releases a space telescope into orbit around the earth. The telescope goes from being stationary to traveling at a speed of 1700 m/s in 25 seconds. What is the acceleration of the
Apollo 17 was the eleventh and final mission of the United States' Apollo program, the sixth mission to land humans on the Moon. Launched at 12:33 a.m. Eastern Standard Time (EST) on December 7, 1972, with a three-member crew consisting of Commander Eugene Cernan, Command Module Pilot Ronald Evans, and Lunar Module Pilot Harrison Schmitt, Apollo 17 remains the most recent manned Moon landing and the most recent crewed flight beyond low Earth orbit. After Apollo 17, extra Apollo spacecraft were used in the Skylab and Apollo-Soyuz Test Project programs. Apollo 17 was the sixth Apollo lunar landing, the first night launch of a U.S. human spaceflight and the final crewed launch of a Saturn V rocket. It was a "J-type mission", missions including three-day lunar surface stays, extended scientific capability, and the third Lunar Roving Vehicle.
The elevator would go around how fast a space shuttle goes. The elevator would carry people up and down from earth to space. This elevator cannot reach the moon… yet. The designs are very simple as it is one cable up to the base level, one cable car attached to the cable by electromagnets, and a base tower inside earth’s orbit that is connected to the cable. This is designed to make travels to space much less in costs as it takes around 500 million dollars to launch a shuttle when it is around $300 to ride up (and maybe more for luggage).
The United States and the Soviet Union – a communist country at the time - competed on the development of weaponry and technological advances. Starting in the late 1950’s, they entered into space race. President Eisenhower’s main objective when he founded NASA, was to place Americans
Training is one of the most important factors in the selection of the crew for both missions being based on their background in Apollo 11 Neil A. Armstrong Commander, Michael Collins Command Module Pilot and Buzz Aldrin Lunar Module Pilot had a Bachelors of Science degree, assigned pilots on a Gemini mission and involve in services for the U.S. as pilots either on Air force, Navy or Military Academy (Jones). In another hand in Apollo 13 crew James A. Lowell, Jr. Commander, John Leonard Swigert, Jr. Command Module Pilot and Fred W. Haise, Jr. Lunar Module Pilot had been back up pilots for different missions also they have a Bachelors of Science Degree (E. M. Jones). Both of the crews for the Apollo missions had training the Commander with responsibility for the overall conduct of the flight operations, the Command Module Pilot for the command module systems and the Lunar Module Pilot for the Lunar Excursion Module systems. The majority of the training was conducted in flight simulators to create as nearly as the procedures for the mission, the simulators were controlled by computers into every part of the projection flight could be programmed to recreate the portion of the mission (H2g2 - Apollo Missions -
One example of history that is retained on the surface of the Moon but has been lost from the surfaces of the terrestrial planets is the simple impact craters. They are very common and very easily spotted on the moon. The simple impact is created from meteorite or comet crashing into the surface of the moon. At the moment of collision, the surface of the moon ejects debris out into space and leave a crater behind. A simple impact crater has a circular shape surrounded by a rim that is elevated from the center of the crater.
