老美阿波羅“登月”在月亮上用的就是這個照相機(圖)

老美阿波羅“登月”項目在月亮上用的就是這個照相機,一模一樣,沒有任何修改,膠卷就是地球上老百姓用的普通柯達膠卷(ektachrome 64 ASA or ISO),本來要裝一個擋板保護普通柯達膠卷防輻射(protective plates were added to the case and film magazine)或鉛包裝(a thick layer of lead around the camera casing),後來沒裝(which according to Hasselblad was not used.)

Cam on the Moon - Hasselblad 500 EL/70

 

Hasselblad were the manufacturer of the camera that took all of the photos on the Apollo missions. Jan Lundberg was the Manager Of Space Projects at Hasselblad from 1966 to 1975 and responsible for the production and building of the Hasselblad 500 EL/70 cameras that were used on the Apollo Missions. He says 'Originally NASA made all the alterations themselves, then they presented what they had done to us and asked if we could do the same, to which we replied yes we can, and we can do it better. We proceeded to make the alterations that were accepted by NASA.' Protective plates were added to the case and film magazine.

H. J. P. Arnold is an astronomer and keen photographer, an expert on space and astrophotography and was the assistant to the Managing Director at Kodak during the Apollo years. He has authored many space photography books. He comments that the film that was supplied by Kodak for the missions was essentially the same as used here on Earth. it was ektachrome 64 ASA or ISO as it is called today. He has commented that you would expect to see some small dots on the films where a high velocity nuclear particle had hit the film, however no evidence of this whatsoever has come forward. The only thing that would protect the film from this damage would be a thick layer of lead around the camera casing, which according to Hasselblad was not used. Let's also remember that the films were changed whilst outside on the Moon's surface and not in a controlled environment.

有重量,尺寸等數據嗎?膠片到底耐多高溫度?看著表麵積很大,鉛的溫度升得更快~ -qiasini- 給 qiasini 發送悄悄話 (0 bytes) () 11/15/2011 postreply 20:34:53

咱也是兩眼一抹黑隻能上網瞎搜。高溫是問題,低溫也是問題,還有月亮上換膠卷哪! -iwbb- 給 iwbb 發送悄悄話 iwbb 的博客首頁 (0 bytes) () 11/15/2011 postreply 20:57:04
