http://www.mext.go.jp/b_menu/shingi/uchuu/...ts/04061101.pdf

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.

above for ease of reference

page 62

fig. III-1-3 Orbital position of Nozomi on the Sun-Earth fixed system

Here, at the centre is the Sun and just to its right is where we are. The only remaining character set on this figure in 2 O'clock position says "Nozomi orbit as seen from the Earth".

End of page 62

page 63

fig. III-1-4 Operational sequence during 24 to 25 April

Note: Netted area corresponds to operational time with Usuda station in Japan. (some 10km from my mountan cottage in central Japan highland!)

(I view this time line to be consisting of 2 columns, one black and the other in red)

(Looking at the black column from top to bottom, still following the times on themain time line):

22:15 MTX_RNG_B (TLM modulation OFF)

02:00 Observation mode change

03:00 Ditto

03:25 Ditto

07:35 TLM editing mode change

07:43 Earth persuit ENA (some kind of enabling activity?, P)

09:00 Earth persuit judgement permitted

10:10 Earth persuit DIS

10:20 TLM editimg mode change

17:37 Time specification CM: TMX_TLM_MOD_ON (TLM modulation)

17:57 Time specification CM: TLM editing mode change

18:32 TMX_TLM_MOD_ON (TLM modulation ON)

18:52 DR REC->STBY

(What follows from here is the column in red, sometimes corresponding to entries in black on the left and there are 5 entries)

1. from 22:15 UDSC LOS to 07:00 is the period in which the failure (or accident) is thought to have taken place.

2. at about 09:00 No action taken* estimated from the reception level on the ground

3. at around 17:00 No action taken

4. at around 18:00 Recption despite TLM modulation being OFF

5. (against 18:32 black entry) No action taken

end of page 63
