"she was scheduled to be the CAPCOM for the STS-117 shuttle mission next month"
Wow, THAT"s a scary thought.
You cannot let anyone that unstable be in charge of millions of dollars worth of NASA equipment, not can you trust them with classified information. Her career is over.
And I wouldn't be surprised IF meth was involved.
Her arrest photo shows someone deteriorating and uncomposed.
Do a google search of the degrees that meth addiction can take with photographs.
