The descent probe is a carry-on small spacecraft (< 100 kg), to be deployed by the mother spacecraft, that brings itself onto a collisional trajectory with the targeted planetary body in a simple manner. A possible science payload includes instruments for surface imaging, characterisation of the neutral exosphere, and magnetic field and plasma measurement near the target body down to very low-altitudes (~1 km), during the probe’s fast (~km/s) descent to the surface until impact. The science goals and the concept of operation are discussed with particular reference to Europa, including options for flying through water plumes and after-impact retrieval of very-low altitude science data. -
Dear Secretary Salazar: I Strongly
Dear Secretary Salazar: I strongly oppose the Bush administration's illegal and illogical regulations under Section 4(d) and Section 7 of the Endangered Species Act, which reduce protections to polar bears and create an exemption for greenhouse gas emissions. I request that you revoke these regulations immediately, within the 60-day window provided by Congress for their removal. The Endangered Species Act has a proven track record of success at reducing all threats to species, and it makes absolutely no sense, scientifically or legally, to exempt greenhouse gas emissions -- the number-one threat to the polar bear -- from this successful system. I urge you to take this critically important step in restoring scientific integrity at the Department of Interior by rescinding both of Bush's illegal regulations reducing protections to polar bears.

Global Scale Impacts
Global Scale Impacts Erik Asphaug Arizona State University Gareth Collins Imperial College, London Martin Jutzi University of Bern Global scale impacts modify the physical or thermal state of a substantial fraction of a target asteroid. Specific effects include accretion, family formation, reshaping, mixing and layering, shock and frictional heating, fragmentation, material compaction, dilatation, stripping of mantle and crust, and seismic degradation. Deciphering the complicated record of global scale impacts, in asteroids and meteorites, will lead us to understand the original planet-forming process and its resultant populations, and their evolution in time as collisions became faster and fewer. We provide a brief overview of these ideas, and an introduction to models. 1. Introduction v1 < v2 are the velocities of the target and projectile in the center of mass frame.

Walter Alvarez,Professor
DEPARTMENT OF EARTH & PLANETARY SCIENCE DEPARTMENT UPDATE 2017 -2018 FROM THE CHAIR WELCOME TO OUR ANNUAL UPDATE write this introduction after returning from our summer geology field camp. What a treat. I met many of the students when they took their first geoscience class, EPS 50. The capstone field course showed how much these new alumni Ihave grown during their time in EPS to develop into creative and talented geoscientists. On page 13 we hear from one of our 66 new graduates, Departmental Citation recipient Theresa Sawi, about her efforts to understand how earthquakes influence volcanic eruptions. Our faculty, students, staff and alumni continue to make our department one of the world’s best. Our newest faculty member, Bethanie Edwards (page 3), broadens the department’s expertise to include marine biogeochemistry. Along with the arrival of Bill Boos and Daniel Stolper two years ago, we continue to expand our efforts to understand all MARINE SCIENCE aspects of Earth’s changing climate. GET TO KNOW OUR FACULTY There have also been some losses. After 36 years, Tim Teague retired. He may be irreplaceable, but we will try. After three years of dedicated service, always with a smile, Richard Allen’s term as chair ended, and he will continue to direct the Seismological Laboratory. Mark Richards moved to Seattle where he is the University of Washington’s provost. Accolades continue to pour in, and I highlight a few. The American Geophysical Union recognized recent Alumnus Leif BETHANIE EDWARDS Karlstrom with the Kuno Award (page 16) and Professor David Romps with the Atmospheric Sciences Ascent award. -
Appendix I Lunar and Martian Nomenclature
APPENDIX I LUNAR AND MARTIAN NOMENCLATURE LUNAR AND MARTIAN NOMENCLATURE A large number of names of craters and other features on the Moon and Mars, were accepted by the IAU General Assemblies X (Moscow, 1958), XI (Berkeley, 1961), XII (Hamburg, 1964), XIV (Brighton, 1970), and XV (Sydney, 1973). The names were suggested by the appropriate IAU Commissions (16 and 17). In particular the Lunar names accepted at the XIVth and XVth General Assemblies were recommended by the 'Working Group on Lunar Nomenclature' under the Chairmanship of Dr D. H. Menzel. The Martian names were suggested by the 'Working Group on Martian Nomenclature' under the Chairmanship of Dr G. de Vaucouleurs. At the XVth General Assembly a new 'Working Group on Planetary System Nomenclature' was formed (Chairman: Dr P. M. Millman) comprising various Task Groups, one for each particular subject. For further references see: [AU Trans. X, 259-263, 1960; XIB, 236-238, 1962; Xlffi, 203-204, 1966; xnffi, 99-105, 1968; XIVB, 63, 129, 139, 1971; Space Sci. Rev. 12, 136-186, 1971. Because at the recent General Assemblies some small changes, or corrections, were made, the complete list of Lunar and Martian Topographic Features is published here.

The principal point of this program was a detailed scientific analysis of the orbital and surface experiments data derived from Apollo missions 15, 16, and 17. One of the requirements of this program was the production of detailed photo base maps at a useable scale. NASA in conjunction with the Defense Mapping Agency (DMA) commenced a mapping program in early 1973 that would lead to the production of the necessary maps based on the need for certain areas. This paper is designed to present in outline form the neces- sary background informatiox or users to become familiar with the program. MAP FORMAT * The scale chosen for the project was 1:250,000 . The re- search being done required a scale that Principal Investigators (PI'S) using orbital photography could use, but would also serve PI'S doing surface photographic investigations. Each map sheet covers an area four degrees north/south by five degrees east/west. -
