Plan To Bomb Mars For Signs of Climate Change 102

Posted by Zonk from the brute-forces-science dept.
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."

      Sure, but drilling cores is something that needs a lot of equipment and hands-on control. It'd be great for a manned mission, but it's tricky to fit a hundred-foot-plus telescoping drill onto a rover and expect it to work.

      This way you can blast a crater and then analyze the dust spectroscopically.

        • You make a good point. Since Mars has no Earth-like atmosphere, even small meteorites can make it though the atmosphere and have significant reprocussions -- possibly no more or less so than these bombs. Nevertheless, I'd argue that meteorites are natural for Mars, whereas humans bombing its surface are probably not. On Earth, although meteorites sometimes do make it through the atmosphere, I wouldn't want someone to simulate such a natural occurance near where I was located at the time.

      Replies like this, and the moderations of them really makes me realize that there's a lot of people that really have no sense of scale. The world copper reserves are somewhere around 340 million tonnes (http://www.icsg.org/Factbook/copper_world/sd.htm [icsg.org]) . That's about 340,000,000,000 kilograms (340 billion kilograms). The projectile they're talking about sending is 230 kilograms. Expressed as a percentage of our reserves, that's .000000068% of our copper reserves. I wouldn't really worry about losing that much copper.
