Recently, the Canadian astronaut Chris Hadfield has become popular (once sang David Bowie's "Space Oddity" in the space station) said on its social media account that the Mars Express (Mars Express number) at the European Space Administration will usher in software updates. In order to better look for the groundwater of Mars and study and monitor Mars' satellite fire. Because this Mars detection satellite supporting software is designed more than 20 years ago, it is still based on the development environment of Microsoft Windows 98.
The Mars Express number of the European Air Bureau was launched through the Alliance Loe Rockets on June 2, 2003. It consists of two parts, namely the Mars Express Satellite and the Little Hunter No. 2 lander. The former is still running well, but the latter After arriving at the surface of Mars, he lost contact and the task failed. According to the European Air Bureau, the Mars Express satellite will accept a series of upgrades to improve the efficiency and quality of work by improving signal receiving and airborne data processing.
Related upgrade work will be responsible for the Italian Institute of Astronomy (Inaf). In order to make Marsis radio -wave instruments better operation, engineers participating in related work acknowledge that this is a difficult challenge. It is not clear which chip is Mars Express. The theory is at least 90 or above. The Mars Express number is not the first space detection instrument equipped with the X86 architecture CPU. The Hubble Space Telescope uses 80386, and later replaced 80486 in 1999 maintenance.
Of course, NASA's favorite CPU is the custom model PowerPC 750, which belongs to the same structure as Apple's IMAC G3's processor. It also uses this CPU ("NASA Perseverance detector is equipped with the same CPU as the IMAC G3: There are many topics to talk about this news"). This customized chip is specially radiated and called RAD750, which is responsible for custom production by BAE Systems.
