Phoenix carries a Linux operating system to the north pole of Mars

Article title: Phoenix carries a Linux operating system to the north pole of Mars. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

On June 18, May 26 this year, Phoenix Lander successfully landed at the north pole of Mars. later, it found water in ice. This is an amazing discovery. Phoenix is said to be an Immortal Bird, indicating good fortune. This landing was successful, and it was a good experience (probably the blessing of phoenix birds ).

According to relevant reports, the core software of the Phoenix lander control system is a Variant of the Linux operating system (Variant) called "VxWorks \". The program code of VxWorks is embedded on a chip similar to a USB flash disk. if necessary, it can be re-activated. Phoenix's hardware configuration is not high. The CPU (reduced instruction set processor) is 33 mhz (equivalent to Intel 386 processor) and the memory is 128 MB. Phoenix processor and motherboard are both made by IBM.

Phoenix received instructions from the Earth, with a latency of 20 minutes. Therefore, it has strict software requirements and must be able to "self-protect" or even "self-correct ". On the Earth, 1000 to 1500 commands are sent to it every day. if something goes wrong, it will be very troublesome. The aerospace industry is not a joke.

Today, all of us on this planet are proud to claim that, on another very distant planet, the Linux operating system is constantly running on Phoenix. Cool is really exciting ). Solid State Disks (SSD, for example, self-starting USB flash drives) are the future development trend. In the face of this trend, people must adapt (this is a matter of time ).
