Satallite to test Einstien theory

A satellite that will put Albert Einstein's Theory of Relativity to the test is ready to be launched.
Nasa hopes Gravity Probe B will lift off from California on 17 April.

Since it was first proposed in 1959, the project has been aborted and delayed because of technical hiccups many times.

Now it is ready to test two of Einstein's theories about the nature of space and time, and how the Earth distorts them.

The unmanned satellite will orbit 640km (400 miles) above Earth, measuring any slight changes in gravity.
