Exploration of the Moon
Exploration of the Moon The physical exploration of the Moon began when Luna 2, a space probe launched by the Soviet Union, made an impact on the surface of the Moon on September 14, 1959. Prior to that the only available means of exploration had been observation from Earth. The invention of the optical telescope brought about the first leap in the quality of lunar observations. Galileo Galilei is generally credited as the first person to use a telescope for astronomical purposes; having made his own telescope in 1609, the mountains and craters on the lunar surface were among his first observations using it. NASA's Apollo program was the first, and to date only, mission to successfully land humans on the Moon, which it did six times. The first landing took place in 1969, when astronauts placed scientific instruments and returnedlunar samples to Earth.

Contents Early history Space race Recent exploration Plans Past and future lunar missions See also References External links Early history The ancient Greek philosopher Anaxagoras (d. 428 BC) reasoned that the Sun and Moon were both giant spherical rocks, and that the latter reflected the light of the former. His non-religious view of the heavens was one cause for his imprisonment and eventual exile.[1] In his little book On the Face in the Moon's Orb, Plutarch suggested that the Moon had deep recesses in which the light of the Sun did not reach and that the spots are nothing but the shadows of rivers or deep chasms. -

The descent probe is a carry-on small spacecraft (< 100 kg), to be deployed by the mother spacecraft, that brings itself onto a collisional trajectory with the targeted planetary body in a simple manner. A possible science payload includes instruments for surface imaging, characterisation of the neutral exosphere, and magnetic field and plasma measurement near the target body down to very low-altitudes (~1 km), during the probe’s fast (~km/s) descent to the surface until impact. The science goals and the concept of operation are discussed with particular reference to Europa, including options for flying through water plumes and after-impact retrieval of very-low altitude science data. -

THE SOVIET MOON PROGRAM in the 1960S, the United States Was Not the Only Country That Was Trying to Land Someone on the Moon and Bring Him Back to Earth Safely

These lessons will be sent on a bi-weekly basis and allow grade-level focused learning. - AIAA STEM K-12 Committee. THE SOVIET MOON PROGRAM In the 1960s, the United States was not the only country that was trying to land someone on the Moon and bring him back to Earth safely. The Union of Soviet Socialist Republics, also called the Soviet Union, also had a manned lunar program. This lesson describes some of it. Next Generation Science Standards (NGSS): ● Discipline: Engineering Design ● Crosscutting Concept: Systems and System Models ● Science & Engineering Practice: Constructing Explanations and Designing Solutions GRADES K-2 K-2-ETS1-1. Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool. Have you ever been busy doing something when somebody challenges you to a race? If you decide to join the race—and it is usually up to you whether you join or not—you have to stop what you’re doing, get up, and start racing. By the time you’ve gotten started, the other person is often halfway to the goal. This is the sort of situation the Soviet Union found itself in when President Kennedy in 1961 announced that the United States would set a goal of landing a man on the Moon and returning him safely to the Earth before the end of the decade. -

Spacecraft Deliberately Crashed on the Lunar Surface
A Summary of Human History on the Moon Only One of These Footprints is Protected The narrative of human history on the Moon represents the dawn of our evolution into a spacefaring species. The landing sites - hard, soft and crewed - are the ultimate example of universal human heritage; a true memorial to human ingenuity and accomplishment. They mark humankind’s greatest technological achievements, and they are the first archaeological sites with human activity that are not on Earth. We believe our cultural heritage in outer space, including our first Moonprints, deserves to be protected the same way we protect our first bipedal footsteps in Laetoli, Tanzania. Credit: John Reader/Science Photo Library Luna 2 is the first human-made object to impact our Moon. 2 September 1959: First Human Object Impacts the Moon On 12 September 1959, a rocket launched from Earth carrying a 390 kg spacecraft headed to the Moon. Luna 2 flew through space for more than 30 hours before releasing a bright orange cloud of sodium gas which both allowed scientists to track the spacecraft and provided data on the behavior of gas in space. On 14 September 1959, Luna 2 crash-landed on the Moon, as did part of the rocket that carried the spacecraft there. These were the first items humans placed on an extraterrestrial surface. Ever. Luna 2 carried a sphere, like the one pictured here, covered with medallions stamped with the emblem of the Soviet Union and the year. When Luna 2 impacted the Moon, the sphere was ejected and the medallions were scattered across the lunar Credit: Patrick Pelletier surface where they remain, undisturbed, to this day. -

Apollo Over the Moon: a View from Orbit (Nasa Sp-362)
chl APOLLO OVER THE MOON: A VIEW FROM ORBIT (NASA SP-362) Chapter 1 - Introduction Harold Masursky, Farouk El-Baz, Frederick J. Doyle, and Leon J. Kosofsky [For a high resolution picture- click here] Objectives [1] Photography of the lunar surface was considered an important goal of the Apollo program by the National Aeronautics and Space Administration. The important objectives of Apollo photography were (1) to gather data pertaining to the topography and specific landmarks along the approach paths to the early Apollo landing sites; (2) to obtain high-resolution photographs of the landing sites and surrounding areas to plan lunar surface exploration, and to provide a basis for extrapolating the concentrated observations at the landing sites to nearby areas; and (3) to obtain photographs suitable for regional studies of the lunar geologic environment and the processes that act upon it. Through study of the photographs and all other arrays of information gathered by the Apollo and earlier lunar programs, we may develop an understanding of the evolution of the lunar crust. In this introductory chapter we describe how the Apollo photographic systems were selected and used; how the photographic mission plans were formulated and conducted; how part of the great mass of data is being analyzed and published; and, finally, we describe some of the scientific results. Historically most lunar atlases have used photointerpretive techniques to discuss the possible origins of the Moon's crust and its surface features. The ideas presented in this volume also rely on photointerpretation. However, many ideas are substantiated or expanded by information obtained from the huge arrays of supporting data gathered by Earth-based and orbital sensors, from experiments deployed on the lunar surface, and from studies made of the returned samples. -
The Soviet Moon Program
The Moon Race [July 1969] – down to the wire! JAMES OBERG JULY 17, 2019 SPACE CENTER HOUSTON APOLLO-11 FIFTIETH ANNIVERSARY WWW.JAMESOBERG.COM [email protected] OVERVIEW– JULY 1969 Unexpected last-minute drama was added to Apollo-11 by the appearance of a robot Soviet moon probe that might have returned lunar samples to Earth just before the astronauts got back. We now know that even more dramatic Soviet moon race efforts were ALSO aimed at upstaging Apollo, hoping it would fail. But it was the Soviet program that failed -- and they did their best to keep it secret. These Soviet efforts underscored their desperation to nullify the worldwide significance of Apollo-11 and its profound positive impact, as JFK had anticipated, on international assessments of the relative US/USSR balance of power across the board -- military, commercial, cultural, technological, economic, ideological, and scientific. These were the biggest stakes in the entire Cold War, whose final outcome hung in the balance depending on the outcome of the July 1969 events in space. On July 13, 1969, three days before Apollo-11, the USSR launched a robot probe to upstage it DAY BEFORE APOLLO-11 LANDING – BOTH SPACECRAFT ORBITING MOON IN CRISS-CROSS ORBITS THE SOVIET PROBE GOT TO THE MOON FIRST & WENT INTO ORBIT AROUND IT AS APOLLO BEGAN ITS MISSION https://i.ebayimg.com/images/g/T6UAAOSwDJ9crVLo/s-l1600.jpg https://youtu.be/o16I8S3MMo4 A FEW YEARS LATER, ONCE A NEW MISSION HAD SUCCEEDED, MOSCOW RELEASED DRAWINGS OF THE VEHICLE AND HOW IT OPERATED TO LAND, RETRIEVE SAMPLES, AND RETURN TO EARTH Jodrell Bank radio telescope in Britain told the world about the final phase of the Luna 15 drama, in a news release: "Signals ceased at 4.50 p.m.
