New Horizons 9.5-Year Journey to Pluto Continues: Worth the Wait
The first spacecraft dedicated to explore Pluto, its moons and potential Kuiper Belt Objects (KOBs) – New Horizons, is scheduled to cross Neptune orbital path on August 25. It will be the 5th spacecraft to voyage this far after Pioneers 10 & 11 and Voyagers 1 & 2. Traveling at ~52,883 kph, it is performing instrument check outs, homing activities, course corrections and brightness variation measurements of Pluto and Charon until its scheduled hibernation on September 6. New Horizons will wake in December to prepare for distant-encounter operations and monitoring. It is expected to fly by Pluto at ~10,000 km traveling at 14 km/s on July 14, 2015, after traveling about 9.5 years and 4.8B km. The science team is hoping to capture the first ever high-res images of the dwarf planet and its moon Charon, as well as map IR surface composition / temperatures. PI Alan Stern, among others, hopes that discoveries and data from the Pluto system reignite the “planet-status” debate. Two of the five moons, Kerberos and Styx were discovered in 2011 and 2012 – it is likely more may be found. Observations are expected to continue for at least 1 year after its flyby. Hubble space telescope has revealed two potential Kuiper Belt Objects (1110113Y and 0720090F) which may be suitable for New Horizons to target between 2016-2020.

Polar Science and Exploration
The Royal Society of New Zealand hosts the 33rd SCAR Biennial Meetings and Open Science Conference on August 23 – September 3 at the SkyCity Convention Centre in Auckland New Zealand. SCAR is the Scientific Committee on Antarctic Research, an inter-disciplinary committee of the International Council for Science charged with initiating, developing and coordinating high quality international scientific research in the Antarctic region, and on the role of the Antarctic region in the Earth system. SCAR has members and offices in 38 countries. The program includes a session on Astronomy & Astrophysics from Antarctica convened by Emeritus Professor John Storey of the Department of Astrophysics and Optics, University of New South Wales, Australia. This session includes presentations on IceCube, ESCAPE, exoplanet observations from ASTEP to AST3, and prospects for a Planet Formation Imager on the high Antarctic plateau. To the North just 10° below the Arctic Circle, Canadian Space Agency Astronaut David Saint-Jacques is set to conduct Geology Field Training at the Western Clearwater lake, one of a pair of annular impact crater lakes at 56°N by 74°W, Quebec, Canada. Saint-Jacques will be accompanying a team lead by Dr. Gordon Osinski from the University of Western Ontario Centre for Planetary Science and Exploration.
