GEO establishes Haiti supersite
The Group on Earth Observations GEO established a supersite in response to the fatal Haiti earthquake from January 12 (http://supersites.unavco.org/haiti.php). Satellite data from different sensors and various derivates are collected and provided on this website including SAR data, topography data, visible and infrared imagery, GPS data, surface deformation and seismic data. This effort has been made possible by the contribution of national space agencies and data providers worldwide such as NASA, ESA, JAXA, DLR, USGS and others.

Sharp Look from Orbit
The earthquake in Haiti, a human tragedy on the ground, has brought requests to remote sensing and geosciences experts from humanitarian relief agencies for help in mapping the disaster. This article, originally published 19 January 2010 by Der Standard, quotes Earthzine Deputy Editor Christoph Aubrecht, who is a remote sensing and geoinformation scientist at the AIT Austrian Institute of Technology working on geospatial issues of disaster management. Aubrecht translated and adapted this article for Earthzine.

Announcement – Integrative geospatial science for disaster risk management @ EGU 2010
The annual General Assembly of the European Geosciences Union – one of the most prestigious events in the field of geoscience – will take place in Vienna, Austria from 02-07 May 2010. The Assembly will draw a crowd of scientists from all over the world, covering all disciplines of Earth, planetary and space science. Earthzine will support a special session within the Natural Hazards Program Group dedicated to the concept of disaster management, one of the GEOSS societal benefit areas.

‘When the Lights Stay On’ – A Novel Approach to Assessing Human Impact on the Environment
A consequence of the explosive expansion of human civilization has been the global loss of biodiversity and changes to life-sustaining geophysical processes of Earth. The footprint of human occupation is uniquely visible from space in the form of artificial night lighting – ranging from the burning of the rainforest to massive offshore fisheries to omnipresent lights of cities, towns, and villages.

NASA Image of the Day
Orbital Sunrise
The Expedition 24 crew on the International Space Station photographed this image of polar mesospheric clouds illuminated by an orbital sunrise. Polar mesospheric, or noctilucent ("night shining"), clouds usually are seen at twilight, following the setting of the sun below the horizon and darkening of Earth's surface. Occasionally the station's orbital track becomes nearly parallel to Earth's day/night terminator for a time, allowing the clouds to be visible to the crew at times other than the usual twilight because of the station's altitude. This photograph shows polar mesospheric clouds illuminated by the rising, rather than setting, sun at center right. Low clouds on the horizon appear yellow and orange, while higher clouds and aerosols are illuminated a brilliant white. Polar mesospheric clouds appear as light blue ribbons extending across the top of the image. The station was located over the Greek island of Kos in the Aegean Sea (near the southwestern coastline of Turkey) when the image was taken at approximately midnight local time. The orbital complex was tracking northeastward, nearly parallel to the terminator, making it possible to observe an apparent "sunrise" located almost due north. A similar unusual alignment of the ISS orbit track, terminator position and seasonal position of Earth's orbit around the sun allowed for this striking imagery of over the Southern Hemisphere.
