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.

New orbital plan for Nozomi

(here, I will have to explain, rather than translate as follows)

red: Mars
green: Earth
purple: Nozomi

(on this Earth-Mars system main character strings clockwise are)

1. 1st earth swingby: Dec 2002
2. leaving Earth gravitational field: Mars Dec 1998
3. insertion into Mars orbit: end 2003 to early 2004
4. 2nd earth swingby: June 2003

(on this page there is another Earth-Mars system in a square. The Monn is in yellows and Mars is depicted in red, with a short caption near Mars which says "into Mars orbit: Oct 1999)

fig I-3-2 Temp changes at temp measurement point(s?) by 1 bit communication

(Here, I have no idea as to what WANT is, but anyway)

Vertical axis is WANT temp and horizontal is the dates, from 23 July to 1 October. On the upper lef a box contains 5 character strings from top to bottom. The last one at bottom says "fitting of WANT-1".

Similarly, there are 5 character strings all pointing to the slanted line on the graph and the last one at bottom of this group of 5 character strings says "fitting of WANT-1"

The cpation of the arrow pointing vertically upward to the slanted line says "melting point under hydrazine tank pressure (2.2 deg C)"

There is another character string qualifying the same slanted line and this says "temp. increase rate per day of 0.32 deg C"
