  • 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.

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.

  • Trade Studies Towards an Australian Indigenous Space Launch System
    TRADE STUDIES TOWARDS AN AUSTRALIAN INDIGENOUS SPACE LAUNCH SYSTEM A thesis submitted for the degree of Master of Engineering by Gordon P. Briggs B.Sc. (Hons), M.Sc. (Astron) School of Engineering and Information Technology, University College, University of New South Wales, Australian Defence Force Academy January 2010 Abstract During the project Apollo moon landings of the mid 1970s the United States of America was the pre-eminent space faring nation followed closely by only the USSR. Since that time many other nations have realised the potential of spaceflight not only for immediate financial gain in areas such as communications and earth observation but also in the strategic areas of scientific discovery, industrial development and national prestige. Australia on the other hand has resolutely refused to participate by instituting its own space program. Successive Australian governments have preferred to obtain any required space hardware or services by purchasing off-the-shelf from foreign suppliers. This policy or attitude is a matter of frustration to those sections of the Australian technical community who believe that the nation should be participating in space technology. In particular the provision of an indigenous launch vehicle that would guarantee the nation independent access to the space frontier. It would therefore appear that any launch vehicle development in Australia will be left to non- government organisations to at least define the requirements for such a vehicle and to initiate development of long-lead items for such a project. It is therefore the aim of this thesis to attempt to define some of the requirements for a nascent Australian indigenous launch vehicle system.

  • 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
    AIAA AEROSPACE M ICRO-LESSON Easily digestible Aerospace Principles revealed for K-12 Students and Educators. 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.

    IOSR Journal of Computer Engineering (IOSR-JCE) e-ISSN: 2278-0661, p-ISSN: 2278-8727, Volume 18, Issue 2, Ver. I (Mar-Apr. 2016), PP 85-90 www.iosrjournals.org Smart GNC Scheme for Autonomous Planetary Landing Ibrahim Mustafa Mehedi Center of Excellence in Intelligent Engineering Systems (CEIES) King Abdulaziz University, Jeddah, Saudi Arabia AND Electrical and Computer Engineering Department, King Abdulaziz University Jeddah 21589, Saudi Arabia Abstract: The moon or other nearest planets are important destinations for space science and the smart landing is key technology for exploring the different planets without fail. Due to the long round-trip delay of communication with the earth a pinpoint autonomous GNC (guidance-navigation-control) system will be suitable for precise landing. Hazard avoidance is another key issue for a safe landing of future planetary missions. Employing sensors and computers onboard, the lander detects hazards in the landing region, makes quick decision considering mission constraints within exigent time limit and generate trajectory to provide necessary command for guidance module that transfers the lander to a suitable safe landing site. Real time onboard terrain mapping Navigation and Guidance is one which has received much attention in the frame of planetary exploration. The paper illustrates the investigations concerning soft landing for planetary exploration and finally proposed a smart and autonomous GNC scheme based on real time range image measurements technique using laser range finder. Keywords: Planetary landing; Autonomous; Hazard detection and avoidance I. Introduction A several lunar or planetary missions were accomplished in last few decades; the guidance-navigation- control (GNC) technology is getting more important than ever.
