IAC-14,A3,P,31X26111 ZEPHYR: a LANDSAILING ROVER FOR
65th International Astronautical Congress, Toronto, Canada. Copyright ©2014 by the International Astronautical Federation. This work was done by employees of the United States government, and no copyright is asserted in the United States. IAC-14,A3,P,31x26111 ZEPHYR: A LANDSAILING ROVER FOR VENUS Geoffrey A. Landis, Steven R. Oleson, David Grantier, and the COMPASS team NASA John Glenn Research Center, 21000 Brookpark Road, Cleveland, OH, 44135 USA [email protected] With an average temperature of 450 °C and a corrosive atmosphere at a pressure of 90 bars, the surface of Venus is the most hostile environment of any planetary surface in the solar system. Exploring the surface of Venus would be an exciting goal, since Venus is a planet with significant scientific mysteries, and interesting geology and geophysics. Technology to operate at the environmental conditions of Venus is under development. A rover on the surface of Venus with capability comparable to the rovers that have been sent to Mars would push the limits of technology in high-temperature electronics, robotics, and robust systems. Such a rover would require the ability to traverse the landscape on extremely low power levels. We have analyzed an innovative concept for a planetary rover: a sail-propelled rover to explore the surface of Venus. Such a rover can be implemented with only two moving parts; the sail, and the steering. Although the surface wind speeds are low (under 1 m/s), at Venus atmospheric density even low wind speeds develop significant force. Under funding by the NASA Innovative Advanced Concepts office, a conceptual design for such a rover has been done. -

Space Science Reviews manuscript No. (will be inserted by the editor) Origins of the Ambient Solar Wind: Implications for Space Weather Steven R. Cranmer Sarah E. Gibson Pete Riley · · Submitted: June 2, 2017 / Accepted: August 23, 2017 Abstract The Sun’s outer atmosphere is heated to temperatures of millions of de- grees, and solar plasma flows out into interplanetary space at supersonic speeds. This paper reviews our current understanding of these interrelated problems: coronal heat- ing and the acceleration of the ambient solar wind. We also discuss where the commu- nity stands in its ability to forecast how variations in the solar wind (i.e., fast and slow wind streams) impact the Earth. Although the last few decades have seen significant progress in observations and modeling, we still do not have a complete understanding of the relevant physical processes, nor do we have a quantitatively precise census of which coronal structures contribute to specific types of solar wind. Fast streams are known to be connected to the central regions of large coronal holes. Slow streams, however, appear to come from a wide range of sources, including streamers, pseu- dostreamers, coronal loops, active regions, and coronal hole boundaries. Complicat- ing our understanding even more is the fact that processes such as turbulence, stream- stream interactions, and Coulomb collisions can make it difficult to unambiguously map a parcel measured at 1 AU back down to its coronal source. We also review re- cent progress—in theoretical modeling, observational data analysis, and forecasting techniques that sit at the interface between data and theory—that gives us hope that the above problems are indeed solvable. -
