  • 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. Apollo 12 Lunar Module Intrepid prepares to descend towards the surface of the Moon. NASA photo. 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.

Ta »majhen korak za človeka, a velikanski skok za človeštvo« je bil storjen 20. julija 1969, ko sta Neil Armstrong in Edwin Aldrin v lunarnem modulu Eagle (tj. Orel) pristala poleg Malega zahodnega kraterja v Morju tišine (slika 1). Okrogla obletnica je priložnost, da se ozremo nazaj in osvežimo dogod- ke iz pionirskih časov osvajanja vesolja.

Mejo med Zemljino atmosfero in vesoljskim prostorom (angl. outer space) imenujemo Kármánova ločnica in je približno sto kilometrov nad površjem Zemlje. Nad to višino za letenje ne veljajo več zakoni aerodinamike, ampak je mogoče zgolj še letenje po zakonih balistike, torej na raketni pogon. Pomembna je tudi v pravnem smislu, saj se tu konča zračni prostor držav in začne veljati mednarodno vesoljsko pravo. Kot vemo, letijo potniška letala na višini približno deset kilometrov. Nedavni rekordni polet z jadralnim letalom je dosegel višino 23 kilometrov nad morjem, vendar s pomočjo stratosferskih zavetrnih valov, ki nastajajo zaradi izredno močnih zračnih tokov med visokimi gorskimi vrhovi Andov (Ebbesen Jensen, 2019).

  • 170221 Sps, Phase-Standing Whistler
    Symposium on Planetary Science 2017, February 20−21, Sendai Phase-standing whistler fuctuations detected by SELENE and ARTEMIS around the Moon Yasunori Tsugawa1, Y. Katoh2, N. Terada2, and S. Machida1 1Institute for Space-Earth Environmental Research, Nagoya University 2Department of Geophysics, Tohoku University Abstract Low frequency (<~0.01 Hz) magnetic fluctuations around the Moon in the solar wind have been reported since 1960s. They are extended upstream of the lunar wake edge along the interplanetary magnetic field lines. We analyze magnetic field data detected by SELENE and ARTEMIS to reveal generation processes of the fluctuations. Our analyses indicate that observed polarizations of the magnetic fluctuations are determined by the spacecraft velocity: right-hand polarization when S/C moves downstream, left-hand polarization when S/ C moves upstream. This fact suggests that their phase velocity in the Moon frame is smaller than the spacecraft velocity and they are R-mode in plasma frame, i.e., they are phase-standing whistlers. They are possibly generated as bow waves around the lunar crustal magnetic anomalies and/ or ballistic fluctuations carried by electrons modified through the wake. 6432 NESS AND SCHATTEN INTERPLANETARY MAGNETIC FIELD FLUCTUATIONSverse to the average6429 field direction.

  • 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.

Since 1961, the building has been the principal facility for monitoring telemetry communications data during ELV launches and until 1995 it processed scientifically significant ELV satellite payloads. Still in operation, Hangar AE is essential to the continuing mission and success of NASA’s unmanned rocket launch program at KSC. It is eligible for listing on the National Register of Historic Places (NRHP) under Criterion A in the area of Space Exploration as Kennedy Space Center’s (KSC) original Mission Control Center for its program of unmanned launch missions and under Criterion C as a contributing resource in the CCAFS Industrial Area Historic District.

    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.
