Amongst the concepts for future large-scale facilities in astronomy is the next-generation ‘Square Kilometre (1KT)’ radio telescope. The purpose is to provide a facility with an order-of-magnitude increase in collecting area compared with that currently available. The requirement is based on the premise that significant new discoveries occur with each leap in effective collecting area. Groups in several countries (Australia, Canada, China, France, India and the Netherlands) are interested in constructing such a telescope operating in the cm to m wavelength range, and an URSI-IAU Working Group has been set up to coordinate the various interests. Although the project is science-driven, its realization will provide a great technological challenge. For instance, new concepts such as ‘flat-tile’ antennas will require consideration.

As was previously disclosed, on February 4, 2003, GeoGlobal entered into a Production Sharing Contract ("PSC") with the Government of India and others covering the 1850 square kilometre Exploration Block KG-OSN-2001/3 ("Block") offshore east coast of India. Under the PSC, the operator of the development activities is Gujarat State Petroleum Corporation Limited of India ("GSPC"), a party to the PSC. Under the PSC, GeoGlobal and the other contracting parties have the right to conduct seismic surveying and exploratory drilling activities on the block for a period of up to 6 1/2 years. Under the first of the three phases of exploration activities, 14 exploration wells are to be drilled over a period of up to 2 1/2 years. Under the remaining two phases of the exploration activities, an additional 6 exploration wells are to be drilled.

Square kilometre (U.S.spelling: square kilometer), symbol km², is a decimal multiple of theSIunitofsurface area, thesquare metre, one of theSI derived units. 1 km² is equal to: 1,000,000 m²100 ha (hectare)Conversely:1 m² = 0.000 001 (10-6) km²1 hectare = 0.01 (10-2) km²1square mile= 2.589 988 km²1 acre = 0.004 047 km², 40.47 ha or 4047 m²Note: "km²" means (km)², square kilometre or kilometre squared, and not k(m²), kilo–square metre. For example, 3 km² is equal to 3 * (1,000 m)² = 3,000,000 m², not 3,000 m².

Some urban areas may contain commercial and industrial districts, railway yards, airports, parks and other uninhabited areas that result in blocks with population densities of less than 400 persons per square kilometre. In general, the impact on the total population within urban areas is minor, but the impact on specific urban land areas could be significant. This would affect any programs or research based on precise distance or land area measurements related to individual urban areas.

The new 40-square-kilometre concession is in an area known to be favourable for gold, a fact that is evidenced by the ongoing activities of artisinal gold miners in the area. The concession is very close to the Buckley's Reef area, which has been actively mined for gold by small-scale miners.

A square kilometre (sometimes written km² ) is based on the SI unit of measurement of area, the square metre. It is the area inside a square that has each side equal to 1 kilometre (1000 metres). This way of talking about area is often used to say how much land there is, on a farm or in a city, for example.
