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.

Fig. III-1-5 Signal reception strength changes from Nozomi received at Usuda (Japan) station's (60m dish)

Unlike normal recption which shows a tendency that strength is max. in the middle and amplitude is min. in the middle we find on 25 April, instead, that strength is decreasing to the right and amplitude is monotonously increaseing.

This corresponds to the situation in which automatic (or autonomous) Earth searching is not being activated (or obeyed).

Characters on the graph is red says "at normal times".

Character string in red on the graph says "Time of accident (estimate)".

Fig. III-1-7 Strength changes since (or after ) year 2000 in the number (?) of high energy particles suffered by Nozomi

Graph above : Average number of counts per every spin (about 8 seconds) of the satellite in a day.

Character string in red says "020421 (data saturated)".

Graph below: Cumulative flux (cmXX2/str) since (or after) year 2000.
