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 II-2-3 Number of cycles of valve open/close action

(this table, I consider it to be consisting of 6 rows)

(top row headers are from left to right)

category: status: number of cycles, in this order

C1R2: exposure to oxidiser vapour
C1R3: immersion in oxidiser liquid

(status members from top to bottom are):

(1): before exposure
(2): immediately after exposure (0.3 MPa)
(3): 16.5 hours after exposure
(4): vapour pressure reduced to 1 atmosphere
(5): after gas is purged

(6) during immersion in running liquid (differential pressure of 0.35 MPa and 5 hours continuous)
(7): after liquid is purged
(8): after cleaning and drying
