Google has begun offering the first high-resolution imagery from the GeoEye-1 satellite it helped sponsor--but only as an optional layer in Google Earth for now

Arduino-based kits let students design and test experiments and then upload them to actual Cubesat satellites, where their experiments will be conducted and results sent back to students. Kits start at only $150.

How geeks show they care. Use Google Maps, Google Earth, and satellite imagery like you never have before.

Geolocation, also called geotagging, is the practice of associating a digital resource with a physical location. A photographer, for example, might include the longitude and latitude coordinates for where a picture was taken, allowing others to pinpoint that location on a map. Increasingly, geolocation is being applied to infrastructure components and end-user devices for the purpose of knowing where people are. This additional layer of location data can make resources much more useful to a broad range of users.

Oil spills in the Baltic Sea have continued to drop off in recent years as a result of various authoritative measures, revised legislation and improved aerial and satellite surveillance. Ross Davies takes a closer look at the region's success story Some years back, the Baltic Sea had something of a reputation as being a cradle for oil spills.The figures speak for themselves.

Mildura Solar Power Station is a concentrating photovoltaic (CPV) project being built in Carwrap, south of Mildura in the state of Victoria, Australia. The project will use high performance solar cells used to power satellites. The plant was proposed to have an installed capacity of 100MW initially to reduce the annual greenhouse gas emissions by 396,000t.

In the battle to reduce energy poverty, the opportunities that satellite imaging data offers could be key to shining a light on wasteful inefficiencies. Andy Tunnicliffe speaks to E.ON to find out more about a project to use space-based technology to improve energy efficiency.
