The Van Allen Probes' Contribution to the Space Weather System
L. J. Zanetti et al. The Van Allen Probes’ Contribution to the Space Weather System Lawrence J. Zanetti, Ramona L. Kessel, Barry H. Mauk, Aleksandr Y. Ukhorskiy, Nicola J. Fox, Robin J. Barnes, Michele Weiss, Thomas S. Sotirelis, and NourEddine Raouafi ABSTRACT The Van Allen Probes mission, formerly the Radiation Belt Storm Probes mission, was renamed soon after launch to honor the late James Van Allen, who discovered Earth’s radiation belts at the beginning of the space age. While most of the science data are telemetered to the ground using a store-and-then-dump schedule, some of the space weather data are broadcast continu- ously when the Probes are not sending down the science data (approximately 90% of the time). This space weather data set is captured by contributed ground stations around the world (pres- ently Korea Astronomy and Space Science Institute and the Institute of Atmospheric Physics, Czech Republic), automatically sent to the ground facility at the Johns Hopkins University Applied Phys- ics Laboratory, converted to scientific units, and published online in the form of digital data and plots—all within less than 15 minutes from the time that the data are accumulated onboard the Probes. The real-time Van Allen Probes space weather information is publicly accessible via the Van Allen Probes Gateway web interface. INTRODUCTION The overarching goal of the study of space weather ing radiation, were the impetus for implementing a space is to understand and address the issues caused by solar weather broadcast capability on NASA’s Van Allen disturbances and the effects of those issues on humans Probes’ twin pair of satellites, which were launched in and technological systems. -

Building the ISS is like living in a house while constructing it at the same time. Building and sustaining the ISS requires 80 launches on several kinds of rockets over a 12-year period. The assembly of the ISS Components of the ISS will continue through 2010, when the Space Shuttle is retired from service. The components of the ISS include shapes like canisters, spheres, triangles, beams, and wide, flat panels.

BAS Science Summaries 2018-2019 Antarctic Field Season
BAS Science Summaries 2018-2019 Antarctic field season BAS Science Summaries 2018-2019 Antarctic field season Introduction This booklet contains the project summaries of field, station and ship-based science that the British Antarctic Survey (BAS) is supporting during the forthcoming 2018/19 Antarctic field season. I think it demonstrates once again the breadth and scale of the science that BAS undertakes and supports. For more detailed information about individual projects please contact the Principal Investigators. There is no doubt that 2018/19 is another challenging field season, and it’s one in which the key focus is on the West Antarctic Ice Sheet (WAIS) and how this has changed in the past, and may change in the future. Three projects, all logistically big in their scale, are BEAMISH, Thwaites and WACSWAIN. They will advance our understanding of the fragility and complexity of the WAIS and how the ice sheets are responding to environmental change, and contributing to global sea-level rise. Please note that only the PIs and field personnel have been listed in this document. PIs appear in capitals and in brackets if they are not present on site, and Field Guides are indicated with an asterisk. Non-BAS personnel are shown in blue. A full list of non-BAS personnel and their affiliated organisations is shown in the Appendix. My thanks to the authors for their contributions, to MAGIC for the field sites map, and to Elaine Fitzcharles and Ali Massey for collating all the material together. Thanks also to members of the Communications Team for the editing and production of this handy summary. -

Dispelling the Myth of Robotic Efficiency: Why Human Space
CRAWFORD: HUMAN SPACE EXPLORATION CRAWFORD: HUMAN SPACE EXPLORATION Dispelling the myth of robotic efficiency Ian Crawford explains why human space exploration will tell us more about the solar system than robotic exploration alone. here is a widely held view in the astro- nomical community that unmanned Trobotic space vehicles are, and always will be, more efficient explorers of planetary surfaces than astronauts (e.g. Coates 2001, Cle- ments 2009, Rees 2011). Partly this comes from a common assumption that robotic exploration is cheaper than human exploration (although this isn’t necessarily true if like is compared with like) and partly from the expectation that devel- 1: The increasing size of Mars rovers, from Pathfinder (front left), a Mars Exploration Rover (left), opments in technology will relentlessly increase to Mars Science Laboratory (right). This increase in size (and cost), contrary to predictions that the capability and reduce the size and cost of improved technology will result in smaller and cheaper robots, is mandated by the nature of the robotic missions to the point that human explo- martian surface and complexity of exploration objectives. Human missions would be even larger and ration will not be able to compete. I argue below more expensive, but, crucially, much more capable.

Mutation of Twins Encoding a Regulator of Protein Phosphatase 2A Leads to Pattern Duplication in Drosophila Imaginal Discs
Downloaded from genesdev.cshlp.org on September 28, 2021 - Published by Cold Spring Harbor Laboratory Press Mutation of twins encoding a regulator of protein phosphatase 2A leads to pattern duplication in Drosophila imaginal discs Tadashi Uemura, 1'3 Kensuke Shiomi, 1 Shin Togashi, 2 and Masatoshi Takeichi 1 1Department of Biophysics, Faculty of Science, Kyoto University, Sakyo-ku, Kyoto 606-01, Japan; ~Laboratory of Cell Biology, Mitsubishi Kasei Institute of Life Sciences, Machida-shi, Tokyo 194, Japan The Drosophila gene twins was identified through a P-element-induced mutation that caused overgrowth in posterior regions of the wing imaginal disc. Analyses using position-specific markers showed that the inactivation of this locus induced the formation of extra wing blade anlagen in the posterior compartment of the disc. The duplication was mirror symmetrical, and the line of the symmetry did not correspond to any of the known compartment borders. We isolated the twins gene and found that it encoded one of the regulatory subunits of protein phosphatase 2A (PP2A). These results suggest a novel aspect of physiological roles of protein dephosphorylation; that is, the control of PP2A activity is crucial for specification of tissue patterns.
