3D 67P

Get out your red/cyan glasses and gaze across the surface of Churyumov-Gerasimenko, aka Comet 67P. The stereo anaglyph was created by combining two images from the Rosetta spacecraft's narrow angle OSIRIS camera taken on September 22, 2014. Stark and jagged, the 3D landscape is found along the Seth region of the comet's double-lobed nucleus. It spans about 985 x 820 meters, pocked by circular ridges, depressions, and flattened areas strewn with boulders and debris. The large steep-walled circular pit in the foreground is 180 meters in diameter. Rosetta's mission to the comet ended in September 2016 when the spacecraft was commanded to a controlled impact with the comet's surface.

On Friday 31 March 2017 at 11:00, Einar Bjorgo, manager of UNOSAT, will give an overview of the variety of activities carried out by UNOSAT since 2001.

Over the last 15 years, UNOSAT has helped guide emergency teams through various locations and supported to humanitarian assistance efforts and programmes to protect cultural heritage.

Hosted at CERN, UNOSAT benefits from the Organization's IT infrastructure whenever a situation requires, helping the UN to stay at the forefront of satellite-analysis. Specialists in both geographic information systems (GIS) and analysis of satellite data, supported by IT engineers and policy experts, use this knowledge to produce extremely precise maps of regions of the world affected, or threatened, by natural disaster or conflict.

Not a pipe dream anymore. Space-farming: A long legacy leading us to Mars

more »
Research into space farming has resulted in numerous Earth-based advances (e.g., LED lighting for greenhouse and vertical farm applications; new seed potato propagation techniques, etc.) There are still many technical challenges, but plants and associated biological systems can and will be a major component of the systems that keep humans alive when we establish ourselves on the Moon, Mars and beyond.
