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 III-1-2 Connections within Common Power Supply Interface (CI-PSU) and devices/instruments related to this power supply

(here again, I will have to be descriptive, but my taks is made a lot easier than the last page in that there is a fairly recognisable regular structure in the table. I am talking about squares seen on the table. And, if you agree with me about the rough structure):

C1R1: X-band transmitter power amplifier (XPA)

C1R2: (pointing to C1R1) X-band transmitter (TMX)

C1R3: various Heaters

C1R4: (pointing to C1R3 with a thick arrow in red) Heat Control Electronics (HCE)

(Here, repetition accepted and C and R reversed or exchanged)

R4C1 (same as C1R47)

R4C2: Open/Close status monitor

R4C3: Pressure monitor

R4C4: Power for ignition

R4C5: Rocketry measurment (INS-SA)

C3R1: Ultra stable transmitter (USA)

C3R2: Data Recorder (DR)

C3R3: Timer

C3R4: S-band transmitter

C3R5: Solar Proton Monitor (SPM)

(In addition, there are two more squares in the middle area and the one above the other is):

Telemetry Command Interface

and blue dotted line connection to;

X-band transmitter
S-band transmitter
and Beacon mode/Telemetry mode switching circuit enclosed within a square formed by dotted lines

(and the other below it is):

Common Interface Power Supply Unit (CI-PSU)

including all of the red line connections emanating from tis square

Note for the title of this page (additional) is:

Red solid lines are related to power and the blue dotted lines relate to signal switching system
