Changes on 09-26-10:

• Decreased the rate at which drill bits break down. Also decreased the price of replacements slightly.
• Atmospheric salvagers, gas giant salvagers and asteroid rovers no longer require the mothership to be powered when you launch. However, launching will still consume a few minutes of charge.
• Hopefully fixed a bug that caused atmospheric salvagers not to crash when they lost all power.
• You can no longer exit an asteroid rover onto an asteroid surface without a spacesuit.
