Space probe results - was Einstein right about gravity?; Computing the environmental cost of land management; and nature's answer to radioactive waste.

Gravity Probe - was Einstein right about gravity?

On April 20, 2004, a small spacecraft set out on a giant quest… to answer one of the fundamental questions of our universe. This is the extraordinary Gravity Probe B mission. Beset by funding cancellations, fire and failure - it’s the longest single experiment ever conducted by NASA.

Computing the environmental cost of land management.

Explores the use of scientific modelling to put a dollar value on Land Management.

Nature’s answer to radioactive waste.

Uranium Minerals

Ever since the first nuclear power station was commissioned, the storage of radioactive waste has been a contentious issue. But deep beneath the sands of the Murray basin in North Western Victoria granite deposits may offer a solution to safer storage of radioactive-waste.
