    National Aeronautics and Space Administration The Earth Observer. July - August 2012. Volume 24, Issue 4. Editor’s Corner Steve Platnick obser ervth EOS Senior Project Scientist The joint NASA–U.S. Geological Survey (USGS) Landsat program celebrated a major milestone on July 23 with the 40th anniversary of the launch of the Landsat-1 mission—then known as the Earth Resources and Technology Satellite (ERTS). Landsat-1 was the first in a series of seven Landsat satellites launched to date. At least one Landsat satellite has been in operation at all times over the past four decades providing an uninter- rupted record of images of Earth’s land surface. This has allowed researchers to observe patterns of land use from space and also document how the land surface is changing with time. Numerous operational applications of Landsat data have also been developed, leading to improved management of resources and informed land use policy decisions. (The image montage at the bottom of this page shows six examples of how Landsat data has been used over the last four decades.) To commemorate the anniversary, NASA and the USGS helped organize and participated in several events on July 23. A press briefing was held over the lunch hour at the Newseum in Washington, DC, where presenta- tions included the results of a My American Landscape contest. Earlier this year NASA and the USGS sent out a press release asking Americans to describe landscape change that had impacted their lives and local areas. Of the many responses received, six were chosen for discussion at the press briefing with the changes depicted in time series or pairs of Landsat images.

Zohar March 2013 © 2013 Guy G. Zohar ALL RIGHTS RESERVED ii COMMITTEE MEMBERSHIP TITLE: Ad-Hoc Regional Coverage Constellations of CubeSats using Secondary Launches AUTHOR: Guy G. Zohar DATE SUBMITTED: March 2013 COMMITTEE CHAIR: Dr. Jordi Puig-Suari, Professor Cal Poly Aerospace Engineering Department COMMITTEE MEMBER: Dr. Kira J Abercromby, Assistant Professor Cal Poly Aerospace Engineering Department COMMITTEE MEMBER: Daniel J Wait; Lecturer Cal Poly Aerospace Engineering Department COMMITTEE MEMBER: Dr. Gerald L. Shaw; Senior Research Engineer SRI International iii ABSTRACT Ad-Hoc Regional Coverage Constellations of CubeSats Using Secondary Launches Guy G. Zohar As development of CubeSat based architectures increase, methods of deploying constellations of CubeSats are required to increase functionality of future systems. Given their low cost and quickly increasing launch opportunities, large numbers of CubeSats can easily be developed and deployed in orbit. However, as secondary payloads, CubeSats are severely limited in their options for deployment into appropriate constellation geometries. This thesis examines the current methods for deploying cubes and proposes new and efficient geometries using secondary launch opportunities. Due to the current deployment hardware architecture, only the use of different launch opportunities, deployment direction, and deployment timing for individual cubes in a single launch are explored. The deployed constellations are examined for equal separation of Cubes in a single plane and effectiveness of ground coverage of two regions.

  • 12 G. Riggs, D.K. Hall. an Introduction to the New NASA Suomi-NPP VIIRS
    72nd EASTERN SNOW CONFERENCE Sherbrooke, Québec, Canada, 2015 An Introduction to the new NASA Suomi-NPP VIIRS Snow Cover Data Products GEORGE A. RIGGS1 AND DOROTHY K. HALL2 ABSTRACT A synopsis of the soon-to-be-released NASA Suomi-NPP (S-NPP) snow cover data products produced in the Land Science Investigator-led Processing System (LSIPS) is presented. The cryospheric science of the Suomi-NPP Visible Infrared Imaging Radiometer Suite (VIIRS) instrument builds and expands on the heritage of cryospheric science from the EOS Moderate Resolution Imaging Spectroradiometer (MODIS) instrument. Suomi-NPP was launched on 28 October 2011 from Vandenberg Air Force Base in California with the first image acquired on 21 November 2011. In 2014 NASA selected the LSIPS to work along with science investigators to produce Earth Science Data Records (ESDRs) and improve and revise the algorithms and data products produced for the science community. The NASA VIIRS snow cover algorithm and data products and the processing sequence and contents of the data products are described. Keywords: snow cover, snow cover extent, NDSI, NPP, VIIRS. SNOW COVER AND CLIMATE CHANGE The importance of monitoring snow cover onset, duration and melt date relative to climate change has been made evident in several studies. Satellite and in-situ data show that Northern Hemisphere snow cover extent, and timing of snow melt are changing (Choi, et al., 2010; Brown and Robinson, 2011; Robinson and Estilow, 2013). Derksen and Brown (2012) and Brown et al. (2010) found that snow melt is occurring earlier in the spring season at some locations in the Northern Hemisphere.
