I find it hard to believe that Curiosity actually did the check-in from Mars. It's more likely a NASA PR person did it, just like they do for their Twitter posts "from Mars" (see @MarsPhoenix for example).

The distribution, headed by Thorsten Schneider, aims to deliver the Operating System in such a way that it allows Security Students first hand insight and hands on experience with Security issues within GNU/Linux in order to teach them protection and mitigation techniques
The project's website describes the distribution as 'the most vulnerable, exploitable Operating System ever' and it's true, the developers have ensured that it contains outdated, ill-configured, flawed code and contains GNU/Linux 2.4 Kernel which is known to have many exploitable avenues in itself.
Damn Vulnerable Linux's website can be viewed here."

These are among the scenarios projected for asteroid Apophis, which researchers now say has a 1 in 45,000 chance of hitting Earth on 13 April 2036. Calculations show it would strike somewhere along a narrow track that stretches eastward from Siberia to the west coast of Africa. The threat, while small, is real enough to merit a United Nations protocol for dealing with the problem, experts say."
