It is also the smallest rocky planet, so its gravity is weak, only about 38 percent of Earth's. These conditions make it hard for the planet to hold on to its atmosphere, which is extremely thin, and invisible to the human eye. However, it can be seen by special instruments attached to telescopes and spacecraft like MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging). http://www.physorg.com/news163160543.html Space & Earth Tue, 02 Jun 2009 11:23:05 EST news163160543 The study of ancient lake sediment from high altitude lakes in the Andes has revealed for the first time that mercury pollution occurred long before the start of the Industrial Revolution. http://www.physorg.com/news161885872.html Space & Earth Mon, 18 May 2009 17:18:36 EST news161885872 (AP) -- PC maker Dell Inc. formally banned on Tuesday the export of broken computers, monitors and parts to developing countries amid complaints that lax enforcement of environmental and worker-safety regulations have allowed an informal and often hazardous electronic-waste recycling industry to emerge. http://www.physorg.com/news161354077.html Technology Tue, 12 May 2009 13:38:40 EST news161354077 A previously unknown, large impact basin has been discovered by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft during its second flyby of Mercury in October 2008.
