Hayabusa2 and the Formation of the Solar System PPS02-25
PPS02-25 JpGU-AGU Joint Meeting 2017 Hayabusa2 and the formation of the Solar System *Sei-ichiro WATANABE1,2, Hayabusa2 Science Team2 1. Division of Earth and Planetary Sciences, Graduate School of Science, Nagoya University, 2. JAXA/ISAS Explorations of small solar system bodies bring us direct and unique information about the formation and evolution of the Solar system. Asteroids may preserve accretion processes of planetesimals or pebbles, a sequence of destructive events induced by the gas-driven migration of giant planets, and hydrothermal processes on the parent bodies. After successful small-body missions like Rosetta to comet 67P/Churyumov-Gerasimenko, Dawn to Vesta and Ceres, and New Horizons to Pluto, two spacecraft Hayabusa2 and OSIRIS-REx are now traveling to dark primitive asteroids.The Hayabusa2 spacecraft journeys to a C-type near-earth asteroid (162173) Ryugu (1999 JU3) to conduct detailed remote sensing observations and return samples from the surface. The Haybusa2 spacecraft developed by Japan Aerospace Exploration Agency (JAXA) was successfully launched on 3 Dec. 2014 by the H-IIA Launch Vehicle and performed an Earth swing-by on 3 Dec. 2015 to set it on a course toward its target. The spacecraft will reach Ryugu in the summer of 2018, observe the asteroid for 18 months, and sample surface materials from up to three different locations. The samples will be delivered to the Earth in Nov.-Dec. 2020. Ground-based observations have obtained a variety of optical reflectance spectra for Ryugu. Some reported the 0.7 μm absorption feature and steep slope in the short wavelength region, suggesting hydrated minerals. -

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.

INCLUSIVE EDUCATION AND SCHOOL REFORM IN POSTCOLONIAL INDIA Mousumi Mukherjee MA, MPhil, Calcutta University; MA Loyola University Chicago; EdM University of Illinois, Urbana-Champaign Submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy Education Policy and Leadership Melbourne Graduate School of Education University of Melbourne [5 June 2015] Keywords Inclusive Education, Equity, Democratic School Reform, Girls’ Education, Missionary Education, Postcolonial theory, Globalization, Development Inclusive Education and School Reform in Postcolonial India i Abstract Over the past two decades, a converging discourse has emerged around the world concerning the importance of socially inclusive education. In India, the idea of inclusive education is not new, and is consistent with the key principles underpinning the Indian constitution. It has been promoted by a number of educational thinkers of modern India such as Vivekananda, Aurobindo, Gandhi, Ambedkar, Azad and Tagore. However, the idea of inclusive education has been unevenly and inadequately implemented in Indian schools, which have remained largely socially segregated. There are of course major exceptions, with some schools valiantly seeking to realize social inclusion. One such school is in Kolkata, which has been nationally and globally celebrated as an example of best practice. The main aim of this thesis is to examine the initiative of inclusive educational reform that this school represents. It analyses the school’s understanding of inclusive education; provides an account of how the school promoted its achievements, not only within its own community but also around the world; and critically assesses the extent to which the initiatives are sustainable in the long term.
