  Spirit rover starts Mars drilling
Updated 08 February 2004, 14.33
The Mars rover Spirit has a twin called Opportunity
The Mars rover Spirit has drilled into a rock on the red planet, the first time a robot vehicle has done this.

The vehicle was specially built to explore Mars, but broke down in January and Nasa have been trying to fix it.

Now computer engineers at Nasa have got Spirit working again, and although it took three hours to drill a small hole, Nasa are really excited about it.

It was difficult to fix Spirit, as information had to be sent to Mars from Earth - 200m miles (320m km) away.

Spirit made the hole with a special tool on the end of a mechanical arm that scientists call RAT. That stands for rock abrasion tool.

Spirit isn't the only rover on Mars - another one called Opportunity is exploring the other side of the planet.

They're both looking for evidence that water was once on Mars, because that means there is also a chance that some form of life was there as well.

However, while things are looking up on Mars, Nasa has said they are going to let the Hubble telescope - which is in space - stop working.

It would cost millions of pounds to keep working, and Nasa would rather spend that money on making the International Space Station better instead.
