Okay so even though it is technically the first ever Earth-borne object to ever touch the surface of Mercury, it isn’t as hopeful as one might expect from the planet’s best and brightest scientists.  But in all fairness we have crash landed on Mars, the Moon, and into the clouds of Jupiter, so it’s not uncommon.  The Messenger spacecraft has been in space since 2004, orbiting the Sun multiple times in order to arrive at Mercury in 2008.  Since then it has completed 4,103 orbits and obtained an incredible amount of scientific data as the first ever space probe to...

Haven’t Heard much from Mercury – But we Will Soon

With the MESSENGER probe set to crash into Mercury this month, it’s nice to look back on some of the finest data that it gathered during its tenure orbiting the smallest planet of the solar system. The image shows the Caloris Basin, the largest impact basin on Mercury and one of the largest in the solar system.  The result of a massive asteroid impact during the early days of the solar system, the 1,500 Km wide crater was filled with lava aeons ago when Mercury was geologically active (seen in orange).  Large impacts have punctured the surface of the basin since...
