Earth Day at Home with NASA

Earth Day celebrated its fiftieth anniversary during an unprecedented time in history as the human race fights back against the global spread of a new, or novel, coronavirus—COVID-19. With Earth Day on the horizon and many NASA personnel continuing to do their jobs remotely, the agency had to think quickly about how to participate in the usual Earth Day celebrations around the globe. In the May-June 2020 issue of The Earth Observer, learn how NASA made the decision to shift its celebration from its traditional in-person event with a variety of hands-on activities to engage the public, to one that could be carried out online, encouraging its web and social media followers to collectively appreciate the wondrous beauty of our planet and the extraordinary science that helps us understand how it all works— from the safety of home.

Symposium on Earth Science and Applications from Space with Special Guest Michael Freilich

In January 2020, a Symposium on Earth Science and Applications from Space with Special Guest Michael Freilich took place at the National Academy of Sciences in Washington, DC. The event was organized to pay tribute to the career of Michael Freilich who was director of the Earth Science Division at NASA HQ from 2006–2019, capping off a long and distinguished career in ocean research that spanned nearly 40 years. During his career, Freilich was also a mentor for many other scientists and scientific leaders, many of whom attended the Symposium. We are delighted to refer you to the lead article in the March-April issue of The Earth Observer that provides a detailed summary of the symposium. 

The Earth Observer: Moving Into 2020

The January-February issue of The Earth Observer features NASA’s Land, Atmosphere Near real-time Capability for EOS (LANCE) program, which celebrated its tenth anniversary in 2019; NASA's Earth to Sky Partnership with the U.S. National Park Service; and NASA's exhibit at the Fall Meeting of the American Geophysical Union (AGU), held December 9-13 in San Francisco, CA—which was AGU’s Centennial meeting. 

Celebrating 20 Years of NASA’s Earth Observatory

When the virtual doors of NASA’s Earth Observatory website first opened to the public in April 1999, who could have imagined the world that exists today? When the team published their first content, it is likely they had no idea that 20 years later the site would still be publishing—nor how different the world would be in just two decades. Turn to page 4 of the November-December 2019 issue of The Earth Observer to read about EO’s twenty years of communicating NASA Earth Science.

2019 AGU Schedule of Events at the NASA Booth

NASA Science welcomes you to San Francisco, CA. We will showcase a wide variety of science presentations and cutting-edge, interactive science, technology, and data demonstrations. This year’s program will be held Monday, December 9, through Friday, December 13, 2019. Hyperwall presentations and In-Booth Science Flash Talks will cover a range of research topics, science disciplines, and programs within NASA.

NASA's Science Support Office 2019 Annual Report

The Science Support Office (SSO) supported 17 domestic and international science conferences and 3 public events in 2019. The SSO continues to provide an inspiring and interactive venue for every event during the year, using a unique storytelling approach that allows a variety of audiences worldwide to connect with NASA Science. The 2019 Annual Report provides an overview of these activities with details about new publications, displays, Hyperwall stories, social media, and more!

SHADOZ at 20 Years: Achievements of a Strategic Ozonesonde Network

Twenty years ago, The Earth Observer published an article announcing the start of the Southern Hemisphere ADditional OZonesondes (SHADOZ) project. It began as a two-year initiative to collect measurements of ozone throughout the atmosphere, or ozone profiles, using balloon-borne ozonesondes by coordinating regular launches at 10 stations in the tropics and subtropics. The network reached its 20-year milestone in 2018, thus providing a fitting opportunity to reflect on its scientific contributions. An article in the September-October 2019 issue of The Earth Observer begins with some history and background on SHADOZ, including details on the network and the ozonesonde instrument itself. It then discusses several spinoffs and major scientific and technological advances resulting from SHADOZ.

The Living Legacy of Landsat 7: Still Going Strong after 20 Years in Orbit

The twentieth anniversary of the launch of Landsat 7 on April 15, 1999, is an opportune time to retrace the history leading to modern Earth science data acquisition and use. This article in the July-August 2019 issue of The Earth Observer provides a retrospective, with some insight into why Landsat 7 was a key player in Earth science and related technical endeavors, and how its mission has informed Earth system science to this day. It discusses some of the scientific and technology bases for the Landsat program generally and Landsat 7 specifically, and points out ways in which Landsat 7 crossed organizational boundaries to ensure the best scientific return.

Increasing Information Access for Food Security Monitoring

Over 10% of the global population is undernourished. Of this population, the majority are in developing countries where the situation is only worsening. Timely and reliable information on crop conditions and early warning of impending shortfalls of crop production are critical to achieving food security and ensuring sufficient, reliable food availability and access. In the May-June issue of The Earth Observer, learn how satellite-based Earth observations significantly contribute towards providing crucial crop information, allowing decision makers to track crop development and general condition throughout the growing season, and ultimately supporting decision-making processes related to early disaster response and mitigation measures that reduce food insecurity.

Thirty Years Reporting on NASA’s Earth Science Program

The March-April issue of The Earth Observer marks the thirtieth anniversary of the publication of our first issue (March 1989)—shortly after the official beginning of NASA’s Earth Observing System (EOS) Program. The Earth Observer has adapted over the years, maintaining its role for three decades. It is well known and respected throughout the global Earth science community, with around 5300 subscribers around the world at last count. Now in Volume 31, the newsletter continues to live out the mission it had from its inception: to report timely news from NASA’s Earth Science Program. On page 4 of this issue, Executive Editor, Alan Ward, offers his perspective on the publication’s evolution over the time he has been involved.
