Nozomi in perspective, Revisiting the causes of failure Options

Above pdf file will be translated for aspiring students in aeronautics, control engineering etc. so that in future lay people like me will be able to enjoy planetary scenes and events without worrying about failures.

The overall title is "Looking into the causes of failure and trying to find the right measures to take for the future with respect to the 18th scientific satellite (PLANET-B ) not inserted into Mars orbit as planned" and it is dated 21 May 2004.

This file is very much detailed at 1.1 megabytes and the number of pages is about 40, I think. In addition, I will be translating 3 more files after this particular file. They will be;

1. ISAS file with views and comments on the failure
2. Another ISAS file, a newsletter written out in a series of 4 individual letters.
3. JAXA file, which is a press release and it is a very concise document with just sufficient details.

Re concise link making I tried a few times, but I simply failed and all the links will be fully pasted out as required.

Table IV-2-3 Concrete examples of failure seperation methods

(Inside the top horizontally oblong square says):

Large characters and those enclosed inside ovals are the points of improvements made with Nozomi

(However, I do not find any large characters on this page and next. There are, however, characters shown in red toegther with lines in red as you will see)

(There are two system outlines on this and next page, one on left and the other on right)

(One on left here says): Nozomi's system outline : current

(the only other characters for translation here is inside the top of 3 boxes next to TCI and it says): "Pressure monitor".

(the other one on right here says): Nozomi's system outline with improvement plan (1): Protective resisters in case of Black Box failure.

(the only other characters for translation here is inside the top of 3 boxes next to TCI and it says): "Pressure monitor".

Page 77 (system outline continuued)

(One on left here says): Nozomi's system outline with improvement plan (2): Protective resisters in addtion to switching between CI and PSU ( as indicated by vertically long square in red) + 1 kg in weight ( and the characters in this square says):

"Power control motherboard (within TCI)"

(the only other characters for translation here is inside the top of 3 boxes next to TCI and it says): "Pressure monitor".

(the other one on right here says): Nozomi's system outline with improvement plan (3): Protective resisters in addition to individual power source for every device (+ 3 kg in weight)

(characters in the square above LVDT next to TCI-2 box in red says): "Pressure monitor".
