EO-1 Celebrates 15 YearsOriginally planned as a “one-year mission,” NASA’s Earth Observing-1 (EO-1) satellite celebrated the fifteenth anniversary of its launch on November 21, 2015. EO-1 was originally a technology testbed satel- lite, built quickly and inexpensively. EO-1 is finally heading for the end of its mission, which is pro- jected for October 2016. While the platform and its instruments are operating well, fuel reserves have been exhausted and the satellite has lost its orbital maintenance ability. The impressive milestone of reaching its 15-year anniversary, coupled with the impending end of the mission, provides an excellent time to review EO-1’s origins and goals, its expanded mission, and the utility of the data acquired so far. |

Visit NASA at the 2015 AGU Fall MeetingPlease plan to visit the NASA booth (# 335) during the American Geophysical Union’s (AGU) forty-eighth annual Fall Meeting! This year’s exhibit hall will open on Monday, December 14, and will continue through Friday, December 18. This daily agenda provides presentation times for Hyperwall talks as well as In Booth Science Flash Talks. Scientists will cover a diverse range of topics including Earth science, planetary science, and heliophysics. The exhibit will also feature a wide range of science demonstrations, printed material, and tutorials on various data tools and services. We hope to see you in San Francisco! |

2015: Looking Back and Looking AheadFor NASA’s Earth Science Division, 2015 began with three successful launches—CATS to the ISS to study clouds and aerosols, SMAP to study soil moisture and freeze-thaw state from space, and NOAA’s DSCOVR mission, which includes two NASA Earth Science instruments now transmitting data from the Lagrange point 1 (L1). The Nov-Dec issue of The Earth Observer provides the latest updates on data products, milestones reached, and upcoming missions. The cover photo is a tribute to NASA’s Earth Observing-1 (EO-1) mission, which celebrated its fifteenth anniversary on November 21. The image at left shows the interior of South Carolina on October 8, 2015, as observed by the Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite. Floodwater covered broad swaths of farmland, forests, and wetlands east of the Congaree River. |

COP-21 Hyperwall Science StoriesThe twenty-first Conference of Parties (COP-21) to the United Nations Framework Convention on Climate Change will take place in Paris, France, November 30 to December 11, 2016. Each year, the COP meets for two weeks to discuss the state of Earth’s climate and how best to deal with future climate change. Hosted by the U.S. Department of State, the U.S. Center at COP is a major public outreach initiative to inform attendees about key climate initiatives and scientific research taking place in the U.S. As has been the standard for several years, NASA’s Hyperwall will be set up inside the U.S. Center. This brochure contains most of the science stories that will be shown on the Hyperwall at COP-21 grouped by theme. |

SAGE III on the International Space StationNASA’s Stratospheric Aerosol and Gas Experiment (SAGE) family of remote-sensing-satellite instruments has long measured ozone (O3) concentrations, stratospheric aerosols, water vapor, and other trace gases that influence Earth’s atmosphere. Planned for launch in 2016, SAGE III on the International Space Station will continue the legacy of accurate SAGE measurements. This brochure provides details about the instrument, launch and installation, ground system and data, and more! |

NASA Science Program Support Office 2015 Annual ReportDuring FY2015, the Science Program Support Office (SPSO) supported 24 domestic and international science conferences and public events. Each year the SPSO strives to provide an inspiring and interactive venue, using a unique storytelling approach, that allows a variety of audiences worldwide to connect with NASA Science. The 2015 Annual Report provides a broad overview of these activities, along with details about new Hyperwall stories, publications, social media, key partnerships, and more! |

Observing Snow and Ice Changes from SpaceData from Earth-observing satellite instruments like the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard Terra and Aqua can be used to create maps of snow-cover, ice-cover, and ice-surface temperature. To find out how these datasets are being used, download the three new lenticular flip cards that show Great Lakes ice cover, Greenland ice surface temperature, and North America snow cover from MODIS. |

GPM Data Help Improve Hurricane Forecast TrackThe GPM mission is now well into its second year and data are flowing in from the Core Observatory and the nine constellation members. In the September-October 2015 issue of The Earth Observer we report on the second GPM Applications Workshop. This meeting was an opportunity to formally introduce the capabilities of GPM to the user community and provide overviews of how GPM data products are being used in a broad range of applications—including an example of how a hurricane forecast track is improved when GPM data are assimilated vs. when GPM data are not used. |

EPIC View of Earth and MoreIn the July-August issue of The Earth Observer, we are happy to report that the Deep Space Climate Observatory (DSCOVR) spacecraft was successfully inserted into its orbit at the first Earth-Sun Lagrange point (L1)—about 1.5 million kilometers (930,000 miles) from Earth—on June 7, 2015. At this time, all instruments are undergoing test and in-flight calibrations during the commissioning phase. Also in the issue, we discuss NASA's Pre-Aerosol, Clouds, and ocean Ecosystems (PACE) mission, which will continue a multidecade record of ocean color measurements. |
