Rock from outerspace may be from Mercury

A strange green space rock hailed as perhaps the first meteorite ever discovered from Mercury may be too old to have come from the solar system's innermost planet, some scientists say.
Last month, scientists announced that the green-hued meteorite NWA 7325 shares many chemical similarities with Mercury, suggesting it may be the first known visitor from the small, sun-scorched planet. http://yhoo.it/10Mt6lp
If spaceship rides to Mars were available, would you go?
