Hardware & spare items

OMS thruster (spare component)

This thruster was made for an orbital maneuvering system by MSR/ESKA Flowform. Its a preformed spare component which was set for the use of the aft OMS of the TanDEM-X satellite.


ARIANE 5 GAM GAT high pressure vessel (flow formed)


ARIANE 5 "SPELTRA" segment bolts and washer

These screws and washer were taken from the "Speltra" segment of Ariane 5. Before this segment was diplayed in the Dornier museum in Friedrichshafen, Germany it underwent an safety inspection. Therefore these four bolts and washers where removed. 


ISS Columbus RCS power connector cable (spare)

This RCS power connector cable was manufactured by EADS Astrium. After quarantined it was declared as scrap, so that this cable could be owned.


Ariane 5 ATV fairing atop launcher "remove before installation chimney" strip

Before bolting the fairing stage of Ariane 5 the holes were marked with these stripes.Through the upper level of the Final Assembly Building - the so-called 'chimney' - the cylindrical ATV was installed on top of Ariane 5 and carefully bolted to the launcher interface.


Kapton silver foil

This piece of silver kapton foil was used during the procession of manufacturing the two experimental units of the "Capillary Channel Flow" program.  The two units were manufactured during March to August 2008 by EADS Astrium. The CCF experiment was launched on STS-131/Flight 19A on April, 5th 2010
  • On January 4, 2011, CCF began remote controlled experiment operations at ZARM in Bremen, Germany.
  • On January 2, 2011, CCF completed full commissioning (a series of checkout tests) at MSFC.
  • On December 27, 2010, CCF was installed in the Microgravity Science Glovebox (MSG) by Increment 26 commander, Scott Kelly.

Unique OV-103 Discovery  tracer pattern tile

This very unique tracer pattern and fit check tile was used during maintenance operations of Space Shuttle Discovery.
To prevent any confusion with flight LRSI (Low-temperature Resistant Surface Insulation) tiles, this tracer pattern tile was painted in contrairiwise black . The tile has a specific ID which reads:

FWD307-1 121-203
OML P1 OV 103

By identifing this tile the ID means:
FWD307-1 121-203  = ForWarD Area 307-1 121-203 (end item control nr.)
OML P1 = Outer Mold Line (outer shape)  Port Window#1
OV103 = Orbter Vehicle 103 (Rockwell ID for Discovery)
T36656 = Tracer 36656 (renamed in T3C656)
V070-391020-393 = VO70 (Rockwell tile identity code)- 391020 (location area)- 393 (tile number)

Due investigation the replacing tile was located in the cockpit area, directly under Port Window #1. A tile map, presented in the STS-132 JOINT SSP / ISS FLIGHT READINESS REVIEW showed direct position (yellow marked):

An image made during Discovery's construction shows more of these tiles (black square)

Another closeup image made made in orbit shows the original tile with the same shape:


Polyuretahen tiles were used to prevent aerodynamic damages to real tiles. They also were used during developement and testing of the orbiter, as well as during maintenance operations, such as Discovery's Orbiter Down Maintenance Period (ODMP) at Palmdale/FL in 1995. This PU foam tracer pattern was used to machine a V070-391020-393 flight tile of LI-2200 material.

A FOIA (Freedom of Information Act) concerning the tracer pattern was made at the Johnson Space Center.  A complete paperwork of 31 pages resulted in the request and approve the originality of the tile.
Therefore this is a very rare and unique itemconcerning the history and the building of OV-103.
