Paul Morris edited and produced an hour-long documentary about HST, which aired on NASA TV on April 24th, the date of its initial launch. The video is available to view on hulu and is available here: “NASA’s Incredible Discovery Machine: The Story of the Hubble Space Telescope” https://www. youtube.com/watch?v=Lo43Gq_Xe1M. (Provided by P. Morris.) GESTAR Annual Report 2019– 2020 | 3 Image from “Why NASA is sending rockets into Earth’s leaky atmosphere.” (Provided by J. Ng.) Joy Ng was a video producer of “Why NASA is sending rockets into Earth’s leaky atmosphere,” which discusses the phenomenon that occurs in the Arctic: “In the tiny Arctic town of Ny-Ålesund, where polar bears outnumber people, winter means three months without sunlight. The unending darkness is ideal for those who seek a strange breed of northern lights, normally obscured by daylight. When these unusual auroras shine, Earth’s atmosphere leaks into space. NASA scientists traveled to Ny-Ålesund to launch rockets through these auroras and witness oxygen particles right in the middle of their escape. Piercing these fleeting auroras, some 300 miles high, would require strategy, patience — and a fair bit of luck. This was NASA’s VISIONS-2 mission, and this is their story. VISIONS-2 was just the first of many. Over the coming months, rocket teams from all over the world will launch rockets into this region as part of the Grand Challenge Initiative— Cusp, an international collaboration to study the mysteries of the polar atmosphere.” The Goddard YouTube version of this video, “Launching Rockets Through the Leak in Earth’s Atmosphere” at https://youtu.be/bSt5peITUBo, was announced as a finalist in the Professional Documentary category at the Raw Science Film Festival. 4 | GESTAR Annual Report 2019 – 2020 Letter from the GESTAR Director This report is the ninth NASA Goddard Earth Sciences, Technology and Research (GESTAR) cooperative agreement annual Report, encompassing the period 11 May 2019 - 10 May 2020. GESTAR continues to be led by the Universities Space Research Association (USRA), with Morgan State University (MSU), the Global Science and Technology (GST), the I.M. Systems Group (IMSG), and The Johns Hopkins University (JHU) as current partners. All members of the team continue to contribute very effectively to the success of the NASA mission. This report summarizes the accomplishments and activities of GESTAR Earth and Planetary scientists, model and algorithm developers, engineers, media specialists, video producers, science data visualizers, conceptual animators. Contributions by students, visitors and staff are also included. The research by GESTAR scientists spans a very broad range of fields, predominantly within the Earth Sciences Division, encompassing global modeling and data assimilation, mesoscale meteorology, climate and radiation, atmospheric chemistry and dynamics, cryospheric sciences, ocean ecology, hydrology and land surface processes, biosphere sciences and ecological modeling, geodesy and geophysics. Several GESTAR scientists also contribute to the Solar System Exploration Division, particularly in the fields of planetary atmospheres modeling and Mars exploration. The centrality of remotely sensed NASA data in all these fields of research, and the focus on the success of NASA’s mission, is a crucial aspect of all GESTAR activities. In addition, part of the GESTAR effort focuses on the dissemination of NASA achievements through high-level videos, documentaries, and social media content. Aside from the research and communication accomplishments, this report contains sections pertaining to educational activities, awards, and public outreach. A separate Appendices report contains publications, presentations, proposals and grants. This year, as in previous years, and in spite of the hardship caused by the pandemic, GESTAR has continued to strive for excellence, has kept producing outstanding achievements, and has dedicated itself to NASA’s goal of expanding the horizons of human knowledge.

  • Southern Hemisphere Mid- and High-Latitudinal AOD, CO, NO2, And
    Ahn et al. Progress in Earth and Planetary Science (2019) 6:34 Progress in Earth and https://doi.org/10.1186/s40645-019-0277-y Planetary Science RESEARCH ARTICLE Open Access Southern Hemisphere mid- and high- latitudinal AOD, CO, NO2, and HCHO: spatiotemporal patterns revealed by satellite observations Dha Hyun Ahn1, Taejin Choi2, Jhoon Kim1, Sang Seo Park3, Yun Gon Lee4, Seong-Joong Kim2 and Ja-Ho Koo1* Abstract To assess air pollution emitted in Southern Hemisphere mid-latitudes and transported to Antarctica, we investigate the climatological mean and temporal trends in aerosol optical depth (AOD), carbon monoxide (CO), nitrogen dioxide (NO2), and formaldehyde (HCHO) columns using satellite observations. Generally, all these measurements exhibit sharp peaks over and near the three nearby inhabited continents: South America, Africa, and Australia. This pattern indicates the large emission effect of anthropogenic activities and biomass burning processes. High AOD is also found over the Southern Atlantic Ocean, probably because of the sea salt production driven by strong winds. Since the pristine Antarctic atmosphere can be polluted by transport of air pollutants from the mid-latitudes, we analyze the 10-day back trajectories that arrive at Antarctic ground stations in consideration of the spatial distribution of mid-latitudinal AOD, CO, NO2, and HCHO. We find that the influence of mid-latitudinal emission differs across Antarctic regions: western Antarctic regions show relatively more back trajectories from the mid-latitudes, while the eastern Antarctic regions do not show large intrusions of mid-latitudinal air masses. Finally, we estimate the long-term trends in AOD, CO, NO2, and HCHO during the past decade (2005–2016).

  • Planetary Defence Activities Beyond NASA and ESA
    Planetary Defence Activities Beyond NASA and ESA Brent W. Barbee 1. Introduction The collision of a significant asteroid or comet with Earth represents a singular natural disaster for a myriad of reasons, including: its extraterrestrial origin; the fact that it is perhaps the only natural disaster that is preventable in many cases, given sufficient preparation and warning; its scope, which ranges from damaging a city to an extinction-level event; and the duality of asteroids and comets themselves---they are grave potential threats, but are also tantalising scientific clues to our ancient past and resources with which we may one day build a prosperous spacefaring future. Accordingly, the problems of developing the means to interact with asteroids and comets for purposes of defence, scientific study, exploration, and resource utilisation have grown in importance over the past several decades. Since the 1980s, more and more asteroids and comets (especially the former) have been discovered, radically changing our picture of the solar system. At the beginning of the year 1980, approximately 9,000 asteroids were known to exist. By the beginning of 2001, that number had risen to approximately 125,000 thanks to the Earth-based telescopic survey efforts of the era, particularly the emergence of modern automated telescopic search systems, pioneered by the Massachusetts Institute of Technology’s (MIT’s) LINEAR system in the mid-to-late 1990s.1 Today, in late 2019, about 840,000 asteroids have been discovered,2 with more and more being found every week, month, and year. Of those, approximately 21,400 are categorised as near-Earth asteroids (NEAs), 2,000 of which are categorised as Potentially Hazardous Asteroids (PHAs)3 and 2,749 of which are categorised as potentially accessible.4 The hazards posed to us by asteroids affect people everywhere around the world.

And it was indeed a fortunate coincidence that the ninth session of the WMO Executive Committee – known today as the WMO Executive Council (EC) – was in progress precisely at this moment, for the EC members were very quick to realize that satellite technology held the promise to expand the volume of meteorological data and to fill the notable gaps where land-based observations were not readily available.

  • Extreme Weather Events
    Extreme weather events Introduction The further a particular weather event lies from the typical range of that type of event, the more it is likely to be described as an extreme event, irrespective of whether it concerns a violent storm, unusual temperatures, heavy precipitation, drought or flood. 2012 seems to have been a year of extreme weather events (‘superstorm’ Sandy in the USA, high rainfall and floods in the UK, etc.). Other years in the last decade have also contained droughts and wildfires (in the USA and Australia), hurricane Katrina (USA), floods (Pakistan) and heat waves (Russia and France). At the same time it is becoming increasingly accepted that human activity, principally the burning of fossil fuels, is changing the global climate and causing the atmosphere to warm. The average global temperature of the lowermost atmosphere has increased markedly since about 1980. Are the two observations, which operate on different timescales1, connected? Are extreme weather events really becoming more common and/or more severe, or are they perhaps part of the climate’s natural variability? The aim of this document is to investigate these two questions. Some basic physics of a warmer atmosphere As air warms its humidity is able to rise and so the atmosphere carries more water vapour. For example, the water content of the atmosphere increases by 7% for each degree Centigrade rise in temperature, although globally precipitation is expected to rise by only about 2%/°C because relative humidity is typically not expected to change on the global scale.8 1 climate change is defined as changes occurring at least over a few decades whereas extreme weather typically lasts from days to months.

  • Ice& Stone 2020
    Ice & Stone 2020 WEEK 51: DECEMBER 13-19 Presented by The Earthrise Institute # 51 Authored by Alan Hale COMET OF THE WEEK: The Great Comet of 1680 Perihelion: 1680 December 18.49, q = 0.006 AU The Great Comet of 1680 over Rotterdam in The Netherlands, during late December 1680 as painted by the Dutch artist Lieve Verschuier. This particular comet was undoubtedly one of the brightest comets of the 17th Century, but it is also one of the most important comets in history from a scientific perspective, and perhaps even from the perspective of overall human history. While there were certainly plenty of superstitions attached to the comet’s appearance, the scientific investigations made of it were among the beginnings of the era in European history we now call The Enlightenment, and indeed, in a sense the Great Comet of 1680 can perhaps be considered as one of the sparks of that era. The significance began with the comet’s discovery, which was made on the morning of November 14, 1680, by a German astronomer residing in Coburg, Gottfried Kirch – the first comet ever to be discovered by means of a telescope. It was already around 4th magnitude at that time, and located near the star Regulus in the constellation Leo; from that point it traveled eastward and brightened rapidly, being closest to Earth (0.42 AU) on November 30. By that time it was a conspicuous naked-eye object with a tail 20 to 30 degrees long, and it remained visible for another week before disappearing into morning twilight.
