It is all a matter of resolution.
Explanation:
Distant objects are effectively points of light. A single pixel on Hubble's CCD camera is enough to "photograph" a star.
Although Mars is a nearby planet, it would require a lot of pixels of data to obtain a good image of the planet's surface. Mars is too far away to do this with Hubble. The only way a clear photograph of mars can be taken is to send a probe close enough to Mars that it can take a high resolution image.
