Ice& Stone 2020
Ice & Stone 2020 WEEK 34: AUGUST 16-22 Presented by The Earthrise Institute # 34 Authored by Alan Hale This week in history AUGUST 16 17 18 19 20 21 22 AUGUST 16, 1898: DeLisle Stewart at Harvard College Observatory’s Boyden Station in Arequipa, Peru, takes photographs on which Saturn’s outer moon Phoebe is discovered, although the images of Phoebe were not noticed until the following March by William Pickering. Phoebe was the first planetary moon to be discovered via photography, and it and other small planetary moons are discussed in last week’s “Special Topics” presentation. AUGUST 16, 2009: A team of scientists led by Jamie Elsila of the Goddard Space Flight Center in Maryland announces that they have detected the presence of the amino acid glycine in coma samples of Comet 81P/ Wild 2 that were returned to Earth by the Stardust mission 3½ years earlier. Glycine is utilized by life here on Earth, and the presence of it and other organic substances in the solar system’s “small bodies” is discussed in this week’s “Special Topics” presentation. AUGUST 16 17 18 19 20 21 22 AUGUST 17, 1877: Asaph Hall at the U.S. Naval Observatory in Washington, D.C. discovers Mars’ larger, inner moon, Phobos. Mars’ two moons, and the various small moons of the outer planets, are the subject of last week’s “Special Topics” presentation. AUGUST 17, 1989: In its monthly batch of Minor Planet Circulars (MPCs), the IAU’s Minor Planet Center issues MPC 14938, which formally numbers asteroid (4151), later named “Alanhale.” I have used this asteroid as an illustrative example throughout “Ice and Stone 2020” “Special Topics” presentations. -

ESA Strategy for Science at the Moon
ESA UNCLASSIFIED - Releasable to the Public ESA Strategy for Science at the Moon ESA UNCLASSIFIED - Releasable to the Public EXECUTIVE SUMMARY A new era of space exploration is beginning, with multiple international and private sector actors engaged and with the Moon as its cornerstone. This renaissance in lunar exploration will offer new opportunities for science across a multitude of disciplines from planetary geology to astronomy and astrobiology whilst preparing the knowledge humanity will need to explore further into the Solar System. Recent missions and new analyses of samples retrieved during Apollo have transformed our understanding of the Moon and the science that can be performed there. We now understand the scientific importance of further exploration of the Moon to understand the origins and evolution of Earth and the cosmic context of life’s emergence on Earth and our future in space. ESA’s priorities for scientific activities at the Moon in the next ten years are: • Analysis of new and diverse samples from the Moon. • Detection and characterisation of polar water ice and other lunar volatiles. • Deployment of geophysical instruments and the build up a global geophysical network. • Identification and characterisation of potential resources for future exploration. • Deployment long wavelength radio astronomy receivers on the lunar far side. • Characterisation of the dynamic dust, charge and plasma environment. • Characterisation of biological sensitivity to the lunar environment.

Glossary Glossary
Glossary Glossary Albedo A measure of an object’s reflectivity. A pure white reflecting surface has an albedo of 1.0 (100%). A pitch-black, nonreflecting surface has an albedo of 0.0. The Moon is a fairly dark object with a combined albedo of 0.07 (reflecting 7% of the sunlight that falls upon it). The albedo range of the lunar maria is between 0.05 and 0.08. The brighter highlands have an albedo range from 0.09 to 0.15. Anorthosite Rocks rich in the mineral feldspar, making up much of the Moon’s bright highland regions. Aperture The diameter of a telescope’s objective lens or primary mirror. Apogee The point in the Moon’s orbit where it is furthest from the Earth. At apogee, the Moon can reach a maximum distance of 406,700 km from the Earth. Apollo The manned lunar program of the United States. Between July 1969 and December 1972, six Apollo missions landed on the Moon, allowing a total of 12 astronauts to explore its surface. Asteroid A minor planet. A large solid body of rock in orbit around the Sun. Banded crater A crater that displays dusky linear tracts on its inner walls and/or floor. 250 Basalt A dark, fine-grained volcanic rock, low in silicon, with a low viscosity. Basaltic material fills many of the Moon’s major basins, especially on the near side. Glossary Basin A very large circular impact structure (usually comprising multiple concentric rings) that usually displays some degree of flooding with lava. The largest and most conspicuous lava- flooded basins on the Moon are found on the near side, and most are filled to their outer edges with mare basalts. -

Astronomy News KW RASC FRIDAY JANUARY 8 2021 JIM FAIRLES What to expect for spaceflight and astronomy in 2021 https://astronomy.com/news/2021/01/what-to-expect-for- spaceflight-and-astronomy-in-2021 By Corey S. 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. -
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. -
