  • 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.

  • To the Moon and Beyond! Article
    3/12/2020 Achieve3000: Lesson Printed by: Jessica Christian Printed on: March 12, 2020 To the Moon and Beyond! Article PART 1 NEW DELHI, India. Both India and China are moving ahead in space exploration. Both countries launched space missions in 2013. India's Mars Orbiter Mission (MOM) was sent to Mars in November. China's Chang'e 3 spaceship blasted off on its way to the moon in December. India India launched its first spacecraft bound for Mars on November 5, 2013. The craft spent almost a month in Earth's orbit. Then, on November 30, 2013, the orbiter went on its way to the Red Planet. "The Earth orbiting phase of the spacecraft ended. The spacecraft is now on a course to reach Mars after a journey of about 10 months around the sun," the Indian Space Research Organisation (ISRO) said in early December. The 3,000-pound (1,350-kilogram) orbiter is called Mangalyaan. That means "Mars craft" in Hindi. It must travel 485 million miles (780 million Photo credit and all related images: kilometers) to reach an orbit around Mars. It will take about 300 days. It is Arun Sankar K/AP expected to do this by September 2014. This is the Satish Dhawan Space Center in southern India. India sent its first spaceship to Mars in The orbiter will gather images and data. They will help in determining how November 2013. Martian weather systems work. India is also looking to MOM to figure out what happened to the large quantities of water that are believed to have once existed on Mars.

  • 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.

    63rd International Astronautical Congress 2012 Paper ID: 12632 SPACE EXPLORATION SYMPOSIUM (A3) Moon Exploration { Part 1 (2A) Author: Dr. Mylswamy Annadurai ISRO Satellite Centre (ISAC), India, [email protected] Dr. Alex TK India, [email protected] Mr. Krishnan A ISRO Satellite Centre (ISAC), India, [email protected] Mr. Rama Murali G K ISRO Satellite Centre (ISAC), India, [email protected] CHANDRAYAAN-1 MISSION, CHALLENGES AND UNIQUE FEATURES Abstract With the advent of technology, the space exploration studying the characteristic behaviour of planetary system got an impetus and the exploration of our nearest neighbour moon had been the natural sequence in it. Since 1959, though more than 50 lunar exploratory missions have been carried out, many critical and fundamental questions about Moon's origin, its formation and interior structure, chemical/mineralogical composition are still open. India, as one among the very few space faring nations, has chalked out its own roadmap for exploring the moon and other bodies in the solar system. As a first step toward this, Chandrayaan-1 was the first instrumented Indian mission to Moon and also the first Indian Space Research Organization (ISRO) ventured to leave Earth's gravity. This mission was aimed at high-resolution remote sensing of lunar surface. In addition, Chandrayaan-1 released a Moon Impact Probe, which explored the moon from close quarters as it descended, till impact. Chandrayaan-1 spacecraft carrying 11 scientific instruments weighed about 1380kg at the time of Launch and shaped like a cuboid with a solar panel projecting from one of its sides. The state of art subsystems of the spacecraft, some of them miniaturised, facilitate the safe and efficient functioning of its array of scientific instruments.

  • Deep-Space Navigation Using Optical Communications Systems
    Deep-Space Navigation Using Optical Communications Systems 1) 1) 1) By Tomas MARTIN-MUR, Sarah Elizabeth MCCANDLESS, and Reza KARIMI 1)Jet Propulsion Laboratory, California Institute of Technology, Pasadena, CA, USA Optical communication links using lasers can potentially deliver data rates much higher than those possible using radio frequencies. If optical communications equipment is going to be carried by future deep-space missions, this equipment, with some adaptations, could also be used to perform tracking for trajectory determination. A number of experiments have been performed in Earth orbit and in lunar orbit using optical data links, while other missions have demonstrated optical links over interplanetary distances. Laser ranging using corner cube retroreflectors is a well-established technique that has been used for orbit determination of Earth orbiting spacecraft, for geodesy, and for lunar research, achieving centimeter-level precisions, but it is not a practical method for deep-space distances. There are two main optical tracking types that are being considered for deep-space navigation. The first is optical astrometry of spacecraft: a telescope on the ground images the laser beam coming from a spacecraft against the star background, determining its plane-of-sky position as seen from the observatory. This type will greatly benefit from the release of the high-accuracy star catalog produced by ESA’s Gaia mission, allowing for the generation of plane-of-sky measurements with an accuracy similar to that obtained today using VLBI tracking techniques. The second is optical ranging using active optical systems at both ends of the link, requiring a more careful design of the spacecraft optical communications system.

    09 September 2019 The Hindu Editorials Update lqcg% 8 cts # Mahendra's YouTube Channel . The Sentinelese, a negrito tribe that lives on the North Sentinel Island of the Andamans, remains hostile to outsiders. Based on carbon dating by the Anthropological Survey of India, Sentinelese presence was confirmed in the islands to 2,000 years ago. The Govt. of India issued the Andaman and Nicobar Islands (Protection of Aboriginal Tribes) Regulation, 1956 to declare the traditional areas occupied by the tribes as reserves, and prohibited entry of all persons except those with authorisation. Photographing or filming the tribe members is also an offence. The rules were amended later to enhance penalties. But restricted area permits were relaxed for some islands . Almost nine months after American national John Allen Chau was recently. allegedly killed by the Sentinelese on the North Sentinel Island of Andaman and Nicobar islands, a recent publication by the Anthropological Survey of India (AnSI) throws more light on the incident and also the ways of one of the most isolated tribes in the world. Titled The Sentinelese of the North Sentinel Island: A reprisal of Tribal Scenario in an Andaman Island in context of Killing of an American Preacher. “On November 14, Chau left Port Blair and reached the island at night. He spent the entire day of November 15 with the Sentinelese and on the night when he met the fishermen who had transported him to the island, he gave them the dairy in which he had recorded his experience of the day,” the director said. The orbiter is safe in the intended orbit around the moon.
