Plan To Bomb Mars For Signs of Climate Change

Oliver Harris writes "Scientists are planning on launching huge copper slugs at Mars in the hope that they will reveal signs of climate change. Problem: What happens when the Martians launch their own copper slugs back?" From the article: "'It's neat because it's a brute force way to gain access to the subsurface of Mars,' says David Spencer, a team member at NASA's Jet Propulsion Laboratory in Pasadena, California, US. 'The impactor will be very simple and we'll get our first look at material from that depth.' Christensen says that will provide a crucial test for models of Mars's past climate."

Um, I wish they'd use some other metal. We can use all the copper we can get here on earth. How about depleted uranium? I could do with less of that in my life and it works well as a projectile.
