7/7     If the Space Shuttle has no fuel tank, how does it change course when
        it tries to leave orbit and return to earth?  Thx.
        \_ It has small thrusters on it.
           \_ Yep, they jet compressed O2, IIRC.  Basically they just nudge
              themselves "down" a bit, coast down, nose up to come in w/
              the heat tiles facing down, and then once in atmo and not falling
              like a rock can use aileron/elevators and rudder.
              \_ Those are the attitude adjustment nozzles.  It also has a
                 main deorbiting thruster that uses a small amount of rocket
                 fuel.
        \_ for 'in-space' maneuvering, it has two different sets of rockets.
           The RCS thrusters for attitude adjustment and fine maneuvering,
           and the OMS engines (two 'medium sized' rockets on the back) for
           larger orbital adjustments.  -ERic

9/20    How do I change my shell? chsh says "Cannot change ID to root."
        \_ /usr/bin/chsh does not have the SUID permission set. Without
           being set, it does not successfully change a user's shell.
           Typical newbie sys admin (on soda)

12/9    A public company (NASDAQ/NYSE) needs to publicly disclose
        important information right? Is there a way to find data that
        shows who owns most of the stocks, when they're dumping (to measure
        their confidence in the company), and how many people are shorting?
        \_ It has been a few years since I took a business organizations
           course, but from what I remember, there isn't a requirement for

9/18    The Space Shuttle Endeavour is doing a fly over of Nasa Ames on Friday:

        \_ They have reached their cap on car passes!  Ahh!  I wish I heard
           about this earlier! :-(
        \_ I saw it above HW 101 in San Mateo this morning.  I wonder how many
           people in the Bay Area watched it (the real thing, not a broadcast.)

3/9     "First amateur video of Challenger shuttle explosion revealed"
        http://www.csua.org/u/vqh (news.yahoo.com)
        Given that the explosion occured so far up in the sky, why was the
        "boom" sound heard at the same time as the visual explosion?  Shouldn't
        there have been a couple seconds of delay?
        \_ Wake up, sheeple!

        NASA keeps air safety data private to avoid public panic.

           caring about the War on Terrah.
