NASA offers Mars24 \"sunclock\" app for Mac OS X

updated 02:00 am EST, Mon January 12, 2004

NASA Mars24 \"sunclock\"

NASA's that "purports to be derived from the application used in mission control. It's the only app I know that depends on the new Java3D frameworks, and may be the reason why they were released by Apple." [updated with Maestro info]

Meanwhile readers note that the Mars Rover uses a variation of PowerPC chips: "The computer in each Mars Exploration Rover runs with a 32-bit Rad 6000 microprocessor, a radiation-hardened version of the PowerPC chip used in some models of Macintosh computers, operating at a speed of 20 million instructions per second."

    20 million/sec

    That's 20MHz :)

    martian CPU hog ?

    I tried Mars24 a few days ago and found (according to top) that it was using 60% of CPU.

    Nope

    20 MIPS != 20 MHz

    CPU Hog!

    You're not kidding! On my dual 2 GHz G5, Mars24 uses 30% of the CPUs! Not a program to leave on in the background!

    True...but

    20MIPS != 20MHz. That's true. Nevertheless, the processor does run at 20MHz. Writing it out as 20 millions instructions per second is just NASA's way of talking to the layman.

    yes

    yeah...20 MHZ, but thats what they are looking for probably, they don't want to waste clock cycles, and thus save battery life with this slow speed.
