The software on earth is in java, but is the software running on the
thing itself java?
Thats' correct. Look at http://www.cnn.com/2004/TECH/space/0...eut/index.html
Had it been running Microsoft .NET, the payload would be heavier due to more
memory needed to run Windows, the cost higher due to licensing fees NASA
would have to pay Bill Gates/Microsoft, and by now would be sending back the
"blue screen of death" instead of the martian surface!

Read the article carefully. Java is being used to create 3D views of
terrain, and for command and control functions, ON EARTH. The last
paragraph correctly states that Wind River Systems made the embedded
software in the Spirit and Opportunity rovers. They run applications
created by JPL which execute on the VxWorks real-time operating system
(RTOS). I know this because a little of my work is in that RTOS - I
worked for Wind River until recently.
If you want more info on VxWorks, see the web site: www.windriver.com
The VxWorks RTOS also ran the Mars Lander and is in many other active
NASA probes like Stardust.

We can say that Java is most useful language on Mars today :))) You know,
the time of .NET is coming while Java has already took its place in
history. Nothing can change that, Java is simply great thing!
I was thinking, NASA could run some servers which will present Spirit's 3D
visualization. They could use Java3D in some applet so anybody interested
could navigate path that Spirit has traveled. It will be nice to see that.
How many cameras Spirit has anyway?
I was also thinking why all robots or searchers have wheels, I mean if they
are doing some research on land ok than, but it will be easier to use some
flying robot like small helicopter or something for making map. It will have
its platform with solar panels, it can go faster and I think travel lot more
distance. The platform can have wheels so it can move. The helicopter can be
useful to analyze around the platform and navigate platform. Let's say Sprit
and small robo-copter will be ideal combination. It's just suggestion.
At the end flying robots will depend on Mars's atmosphere, right?

Local atmospheric pressure is 7-10 torr. Earth sea level is 760
torr. How many planes do you know that cruise at 100,000 feet absent
any oxygen at all? Martian aircraft are a bad dream.

Why mention oxygen specifically?
The solar panels mentioned would have no
problem with the complete absence of oxygen.
...Though a battery powered chopper would
still be little more effective than one that
uses internal combustion.
And getting back to the original
thrust of this thread.
No, even if it were possible to make
a craft that could fly in Mars' atmosphere,
that would not be controlled by Java either
as it would violate Sun's license.

Java is the worst thing that could happen to computing since the
invention of the chuwing gum hard disk.
It is slow, slow, slow, slow, SLOW, and not to mention slow.
And on top of that it is slow. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |
