Wrong name

The ref used calls them Orbital Replacement Units - Orbital replacement unit currently only covers those for the ISS - This article concentrates on those for the HST. Maybe better to rename this to Orbital Replacement Unit (HST) ? - Rod57 (talk) 11:57, 8 May 2017 (UTC)[reply]

Any objections to the rename to Orbital Replacement Unit (HST) ? - Rod57 (talk) 09:00, 10 May 2017 (UTC)[reply]

Renamed (left lowercase (for now)), and added hatnote at Orbital replacement unit - Rod57 (talk) 10:40, 11 May 2017 (UTC)[reply]

Can we include full list from NASA ref

The archived Langley ref says - "Altogether, some 70 items in the HST can be replaced in orbit. The Orbital Replacement Units are:

Scientific Instrument Control and Data Handling
Faint Object Camera
Wide Field / Planetary Camera
Data Interface Unit for Optical Telescope Assembly
Data Management Unit
DF-224 Computer
Fine Guidance Electronics (3)
Battery (6)
Fixed Head Star Tracker (3)
Rate Sensor Unit (3)
Charge Current Controller (3)
Data Interface Unit for Support Systems Module
Electrical Power Thermal Control Electronics
Power Control Unit
Power Distribution Unit
Fuses (14)
Multiple Access Transponder (2)
Single Access Transmitter (2)
Faint Object Spectrograph
Fine Guidance Sensor (3)
Reaction Wheel Assembly (4)
Solar Array (2)
Low Gain Antenna
Sun Sensor"

but even counting the multiples (N) that doesn't seem to add up to 70 ! - Rod57 (talk) 08:28, 10 May 2017 (UTC)[reply]

2 Faint Object Camera, 3 Wide Field / Planetary Camera, : 19 Faint Object Spectrograph

are called Orbital Replacement Instruments in some NASA docs - Rod57 (talk) 10:52, 11 May 2017 (UTC)[reply]
