Powell | Published: Monday, January 4, 2021 Whatever craziness may be happening on Earth, the coming year promises to be a spectacular one across the solar system. 2020 - It was the worst of times, it was the best of times. First landing on the lunar farside, two impressive successes in gathering samples from asteroids, the first new pieces of the Moon brought home in 44 years, close-up explorations of the Sun, and major advances in low-cost reusable rockets. First Visit to Jupiter's Trojan Asteroids First Visit to Jupiter's Trojan Asteroids In October, NASA is set to launch the Lucy spacecraft. Over its 12-year primary mission, Lucy will visit eight different asteroids. One target lies in the asteroid belt. The other seven are so-called Trojan asteroids that share an orbit with Jupiter, trapped in points of stability 60 degrees ahead of or behind the planet as it goes around the sun. These objects have been trapped in their locations for billions of years, probably since the time of the formation of the solar system. They contain preserved samples of water-rich and carbon-rich material in the outer solar system; some of that material formed Jupiter, while other bits moved inward to contribute to Earth's life-sustaining composition. As a whimsical aside: When meteorites strike carbon-rich asteroids, they create tiny carbon crystals. -

Project Apollo: Americans to the Moon John M
Chapter Two Project Apollo: Americans to the Moon John M. Logsdon Project Apollo, the remarkable U.S. space effort that sent 12 astronauts to the surface of Earth’s Moon between July 1969 and December 1972, has been extensively chronicled and analyzed.1 This essay will not attempt to add to this extensive body of literature. Its ambition is much more modest: to provide a coherent narrative within which to place the various documents included in this compendium. In this narrative, key decisions along the path to the Moon will be given particular attention. 1. Roger Launius, in his essay “Interpreting the Moon Landings: Project Apollo and the Historians,” History and Technology, Vol. 22, No. 3 (September 2006): 225–55, has provided a com prehensive and thoughtful overview of many of the books written about Apollo. The bibliography accompanying this essay includes almost every book-length study of Apollo and also lists a number of articles and essays interpreting the feat. Among the books Launius singles out for particular attention are: John M. Logsdon, The Decision to Go to the Moon: Project Apollo and the National Interest (Cambridge: MIT Press, 1970); Walter A. McDougall, . the Heavens and the Earth: A Political History of the Space Age (New York: Basic Books, 1985); Vernon Van Dyke, Pride and Power: the Rationale of the Space Program (Urbana, IL: University of Illinois Press, 1964); W.

Disclaimer - I claim no authorship for the printed material; except where noted (PW). INDIA AIMS TO BE 1ST COUNTRY TO LAND ROVER ON MOON'S SOUTH POLE India will become the first country to land a rover on the Moon's the south pole if the country's space agency "Indian Space Research Organisation (ISRO)" successfully achieves the feat during the country's second Moon mission "Chandrayaan-2" later this year. "This is a place where nobody has gone. All the ISRO missions till now to the Moon have landed near the Moon's equator. Chandrayaan-2, India’s second lunar mission, has three modules namely Orbiter, Lander (Vikram) & Rover (Pragyan). The Orbiter and Lander modules will be interfaced mechanically and stacked together as an integrated module and accommodated inside the GSLV MK-III launch vehicle. The Rover is housed inside the Lander. After launch into earth bound orbit by GSLV MK-III, the integrated module will reach Moon orbit using Orbiter propulsion module. Subsequently, Lander will separate from the Orbiter and soft land at the predetermined site close to lunar South Pole. -
GSLV Mkiii-M1 Chandrayaan 2
INTRODUCTION Chandrayaan 2 is an Indian lunar mission that will boldly go where no country has ever gone before — the Moon’s south polar region. We aim to improve our understanding of the Moon, which could lead to discoveries that will benefit India and humanity as a whole. These insights and experiences will cause a paradigm shift in how lunar expeditions are approached for years to come, propelling further voyages into the farthest frontiers. WHY ARE WE GOING TO THE MOON? The Moon is the closest cosmic body on which space discovery can be attempted and documented. It is also a promising test bed to demonstrate technologies required for deep-space missions. Chandrayaan 2 attempts to foster a new age of discovery, increase our understanding of space, stimulate the advancement of technology, promote global alliances, and inspire a future generation of explorers and scientists.

Murty1, and Anil Bhardwaj1 1Physical Research Laboratory, Ahmedabad 2Space Application Centre, Ahmedabad 3U. R. Rao Satellite Centre, Bengaluru Email: [email protected] Abstract Alpha Particle X-ray Spectrometer (APXS) is one of the two scientific experiments on Chandrayaan-2 rover named as Pragyan. The primary scientific objective of APXS is to determine the elemental composition of the lunar surface in the surrounding regions of the landing site. This will be achieved by employing the technique of X-ray fluorescence spectroscopy using in-situ excitation source 244Cm emitting both X-rays and alpha particles. These radiations excite characteristic X-rays of the elements by the processes of particle induced X-ray emission (PIXE) and X-ray fluorescence (XRF). The characteristic X-rays are detected by the ‘state-of-the-art’ X-ray detector known as Silicon Drift Detector (SDD), which provides high energy resolution as well as high efficiency in the energy range of 1 to 25 keV. This enables APXS to detect all major rock forming elements such as, Na, Mg, Al, Si, Ca, Ti and Fe. The Flight Model (FM) of the APXS payload has been completed and tested for various instrument parameters. -

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. -

Beresheet 2: Israel
Beresheet 2: Israel drishtiias.com/printpdf/beresheet-2-israel Why in News Recently, Israel launched the Beresheet 2 project aimed at landing an unmanned craft on the moon in 2024. Earlier, Israel’s Beresheet probe crash landed on the Moon. Key Points Background: The Beresheet probe was a private mission to the Moon by Israeli non-profit SpaceIL organisation. Beresheet in hebrew (spoken in Israel) means Genesis. It was successfully launched in February 2019, on board a Falcon 9 rocket from Cape Canaveral (USA) and arrived in lunar orbit in April 2019. It suffered an engine failure as it prepared to land and crashed abruptly on the surface of the moon. 1/2 Beresheet 2: Objective: Conducting experiments and collecting data on behalf of school students. Structure: It will involve launching two landing craft and an orbiter that would circle the moon for years. Cost: It will cost around 100 million dollars raised from international partnerships and donors. Significance: Israel could become the fourth nation to land a spacecraft on the moon after the USA, the former Soviet Union and China. Other Missions to Moon: India has planned a new moon mission named Chandrayaan-3. It is likely to be launched in early 2021. It will be a mission repeat of Chandrayaan-2 and will include a Lander and Rover similar to that of Chandrayaan-2, but will not have an orbiter. Chandrayaan-2 failed which crushed India's dream to become the first nation to successfully touch down on the lunar surface in its maiden attempt. The United Arab Emirates (UAE) has decided to send an unmanned spacecraft to the moon in 2024. -

Beresheet Lunar Landing Site Revealed 20 March 2019
Beresheet lunar landing site revealed 20 March 2019 landing area that could jeopardize the touchdown. In addition, the scientists searched for a location on the Moon where the crust is magnetic, so as to allow the magnetometer on board the spacecraft to carry out its investigation. The landing site was selected together with Prof. Jim Head of Brown University, a member of the SpaceIL team who worked with the NASA Apollo program on landing site selection, among other things. "On the basis of our experience with Apollo, the Serenitatis sites favor both landing safety and scientific reward," he said. The topography of the 140 km (87 mi) diameter area The chosen site is located in the northeastern part containing the potential lunar landing sites in Mare of Mare Serenitatis, a few hundreds of miles east of Serenitatis (arrow).
