Asteroid and Comet Watch

The Asteroid Watch Widget tracks asteroids and comets that will make relatively close approaches to Earth. The Widget displays the date of closest approach, approximate object diameter, relative size and distance from Earth for each encounter. The object's name is displayed by hovering over its encounter date. Clicking on the encounter date will display a Web page with details about that object. The Widget displays the next five Earth approaches to within 4.6 million miles (7.5 million kilometers or 19.5 times the distance to the moon); an object larger than about 150 meters that can approach the Earth to within this distance is termed a potentially hazardous object.

Karl Schwarzschild (9 de octubre de 1873 - 11 de mayo de 1916), fue un físico y astrónomo alemán, nació en Fráncfort del Meno y fue el mayor de seis hermanos de una familia de ascendencia judía.

Karl Schwarzschild

Joven prodigio, a los dieciséis años desarrolló un trabajo sobre la teoría de órbitas celestes y otro de estrellas dobles, que luego se publicarían en la revista Astronomische Nachrichten (Informes Astronómicos). Su talento con las matemáticas se vería potenciado gracias al hijo de un amigo de su padre dos años mayor que él, Paul Epstein, con quien compartía su afición por la astronomía.

Para el año 1891 entra a estudiar a la Universidad de Estrasburgo, y en tres años saca un doctorado en Múnich tras dedicarse a la astronomía observacional, para lo que después trabaja como asistente en el Observatorio Kuffner, donde desarrolló una fórmula para calcular las propiedades de materiales fotográficos.

S New Orion Spacecraft Completes First Spaceflight Test. Major Milestone on Agency's Journey to Mars [image-50] NASA marked a major milestone Friday on its journey to Mars as the Orion spacecraft completed its first voyage to space, traveling farther than any spacecraft designed for astronauts has been in more than 40 years.

“Today’s flight test of Orion is a huge step for NASA and a really critical part of our work to pioneer deep space on our Journey to Mars,” said NASA Administrator Charles Bolden. “The teams did a tremendous job putting Orion through its paces in the real environment it will endure as we push the boundary of human exploration in the coming years.”

[image-69] Orion blazed into the morning sky at 7:05 a.m. During the uncrewed test, Orion traveled twice through the Van Allen belt where it experienced high periods of radiation, and reached an altitude of 3,600 miles above Earth. Orion will open the space between Earth and Mars for exploration by astronauts. A team of NASA, U.S. ULA (@ulalaunch) European Severe Storms Laboratory. ECSS Portal.

Lightning Research Laboratory (UF) Assess the U.S. Climate. Scientific assessments are essential tools for linking science and decision making.

Assess the U.S. Climate

They survey and synthesize science, within and between disciplines and across sectors and regions. They highlight key knowledge that can improve policy choices and identify significant gaps that can limit effective decision making. Assessments also track progress by identifying changes in the condition of the Earth, changes in human response, and advances in science over time.

Assessments have been integral components of USGCRP since our inception. We have a legal mandate to conduct a National Climate Assessment (NCA) every four years, the third and most recent of which was released in May 2014. The NCA: An emerging area of focus for USGCRP is strengthening our capacity to conduct assessments on a sustained basis. National Lightning Safety Institute (NLSI) Home Page. We provide expert training, consulting, education, videos, and witness service on structural lightning safety. We also promote proactive defenses to mitigate the effects of lightning hazards. DISCOVER. The DISCOVER Project The primary objective of the Distributed Information Services for Climate and Ocean Products and Visualizations for Earth Research (DISCOVER) Project is to provide highly accurate, long-term ocean and climate products suitable for the most demanding Earth research applications via easy-to-use display and data access tools.


These products are derived from a large network of satellite microwave sensors going back to 1979. Most of the products are produced in near real-time (3-12 hours) on a 24x7 basis and hence are also suitable for some weather applications. The products include sea-surface temperature and wind, air temperature, atmospheric water vapor, cloud water, and rain rate. A key element of DISCOVER is the merging of multiple sensors from multiple platforms into geophysical data sets consistent in both space and time. Global Hydrology Resource Center (GHRC)
