Mars Rover Controlled By Java

Java, the software developed by Sun Microsystems in the mid-1990s as a
universal operating system for Internet applications, gave NASA a low-cost
and easy-to-use option for running Spirit, the robotic rover that rolled
onto the planet's surface on Thursday in search of signs of water and life.

It may be a bit hard to reach the on/off switch.

If I was to make such a vehicle, I woul dmake sure to allow it to be
rebooted by remote control even when the computer is in some undefined
state, e.g., by having a simple circuit listening to the incoming
signals and when a specific sequence occurs, reboot the main computer.

That's simply not true.


You're right, of course. I had in mind the big commercial jets
when I was comparing the landing speed of 747s with others of the
same general class.
...accomplished pilots practice flapless landings in
case of a system failure.


Absolutely.

NASA is renowned for its antenna failures - the Hubble space

Since they're getting good signal, but meaningless data, the antenna
is not likely to be the problem, is it?
Uncle Al eagerly anticipates a Hummer-2 advert beginning with the $240
million pigmy brain fart that couldn't call home. Anticipating that
its working life would be less than 90 days because of dust
accumulating on its solar panels is also precious. Hey NASA, "blow
job."

One presumes the same engineering glitch is in the other rover.


I wouldn't "presume" anything without considerably more data.
Actually, I would - I presume that NASA has people working on the
problem that are at least as competent as you are ;-)
