JohnsonSubject: SAGE III/Contamination Control/Test Facilities Abstract: The SAGE III Project had to educate our foreign partners in the area of conta

2、mination control.Description of Driving Event: The SAGE III Project was unique in that it incorporated groups from NASA Langley, Ball Aerospace, Russian Space Agency, NIIEM (Russia), K. B. Yuzhnoye (Ukraine), and ILS (Kazakhstan). Most projects that are strictly domestic in nature have no problems w

3、ith gaining an agreement and understanding of test facilities and contamination control. SAGE III basically had to re-invent this understanding with our foreign partners. Our Russian partners had worked the Total Ozone Mapping Spectrometer (TOMS) Project and had an understanding of particle contamin

4、ation, but did not understand molecular contamination (NVR). Many Technical Interchange Meetings (TIMs) were required to gain a mutual understanding of the contamination control requirements that had been established by the US side. Ball Aerospace initially created a contamination control plan for t

5、he project, but NASA-Langley had to roll this into a Contamination Control Procedure and a Cleaning Specification for the Russian side. Ball was a participant in negotiations with our foreign partners, but only NASA could represent the government in our contract with our foreign partners. This was a

6、ccomplished through TIMs and a Contamination Control workshop held in Florida for our foreign (Russian, Ukrainian and Kazakhstan) partners. This was not just a technical job, but required walking a very sensitive cultural/political tightrope so as not to offend anyone. Provided by IHSNot for ResaleN

B. Yuzhnoye, which had been denied previously. Test facilities at NIIEM

8、 Electromechanics Research Institute (Russia) and the Baikonur Cosmodrome (Kazakhstan) were initially inspected and found not to meet the US requirements. Assembly and Test facilities at K. B. Yuzhnoye (Ukraine) were inspected and found to be good, but did not meet the US requirements. Working close

9、ly with all of our partners, the US side provided contamination control equipment (clean tents, garments, gloves, cleaning supplies, etc.) and recommendations for facility upgrades. The Russian, Ukrainian and Kazakhstan partners formed contamination control groups and many upgrades were performed. T

10、est and Assembly Facilities at NIIEM (Russia), K. B. Yuzhnoye (Ukraine) and Baikonur (Kazakhstan) were improved under the direction and guidance of the NASA Langley I & T Team. The response from our foreign partners in making changes to their facilities, initially reluctant, improved as they learned

11、 more about contamination control and the effects on spacecraft hardware. The end results of both the US and foreign partners joint efforts were that the facilities were improved, the foreign partners gained a good understanding of contamination control and requirements for this project were met. Le

12、sson(s) Learned: Expect the Unexpected - Throughout the entire process with the Russian, Ukrainian and Kazakhstan partners, we were subjected to many obstacles, limited resources and knowledge. A project must plan to be self-sufficient when working a project in a foreign country. You must provide ev

13、erything that you think will be needed and then provide for those unexpected situations. Supplies for contamination control need to be provided by the US side. It was our experience that Russian provided supplies did not meet the requirements that had been established. This was evident with isopropy

14、l alcohol (IPA) and ethyl alcohol, clean room garments, clean room wipes, and general clean room facility conditions. You cannot expect your foreign partners to provide supplies that are equivalent to those used in the US, so dont ask them to provide them. The project must also provide contamination

15、 control education to the foreign partners so that requirements that have been established can be fully understood and implemented. Although the understanding of contamination control and the working conditions in Russia and Kazakhstan were different (and difficult at times) from what the US side wa

16、s used to, in no way Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-should this be deemed a negative item. The experience of working with people from other countries that have limited resources was rewarding in that they had a strong desire to learn

17、 and improve their knowledge and systems. We learned from each other in that they (the Russians) are able to do more with less than we could ever consider doing as evidenced by the Mir Space Station.Recommendation(s): A project needs to perform a full assessment of facilities they plan to use and no

18、t accept them on face value. Modifications to the facilities (physical and financial) need to be completed prior to the installation of multi-million dollar instrument(s) like SAGE III.
