老美阿波羅“登月”照相機,耳聽為虛,眼見為實(圖)
可惜啊,老美的阿波羅項目的設計者們在設計阿波羅項目時沒想到月亮上的環境問題,他們以為地球上的高級照相機(Hasselblad 500 EL/70)和柯達膠卷就沒問題了。結果呢,他們用登月的預算拍了一個電視連續劇。
後來,人們問問題了,人們問了月亮上的環境問題,比如說溫度問題(The temperature during the Apollo missions were recorded as being between -180F in the shade to an incredible +200F in full Sunshine.,那啥就說用了各種塗料。
哈哈,耳聽為虛,眼見為實!隻是給相機塗塗料是不夠滴,因為還有鏡頭!
看見鏡頭了嗎?什麽顏色?再看看下麵這個圖
 鏡頭是什麽顏色的?
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.
An important factor to take into consideration is the great variations in temperature that the film would have had to endure whilst on the lunar surface. The temperature during the Apollo missions were recorded as being between -180F in the shade to an incredible +200F in full Sunshine. How could the film emulsion have withstood such temperature differences? The astronauts can be seen to move between the shadows of the rocks and then into full sunlight in some shots. Surely the film would have perished under such conditions?

V妹妹對這個有什麽說法? -qiasini- 給 qiasini 發送悄悄話 (0 bytes) () 11/19/2011 postreply 16:00:10

阿波羅宇航員可不是一般的遊客,人家是帶了溫度計去月亮旅遊滴,還測了溫度 -iwbb- 給 iwbb 發送悄悄話 iwbb 的博客首頁 (272 bytes) () 11/19/2011 postreply 16:11:59

那個測的不算,不是正午時:)但可參考:200F是多少度?可反推當時太陽高度~ -qiasini- 給 qiasini 發送悄悄話 (0 bytes) () 11/19/2011 postreply 16:18:37

俺靠~嚇俺一跳:200F是93度,不就是老J估算的45度高太陽時月亮表麵溫度88度嗎?老J牛啊~ -qiasini- 給 qiasini 發送悄悄話 (0 bytes) () 11/19/2011 postreply 22:59:05

哪位大拿真該查查這是哪次登月?為啥要選這燙死豬的時候登月? -qiasini- 給 qiasini 發送悄悄話 (0 bytes) () 11/19/2011 postreply 23:06:04

看來老J還沒對科學臣服,不愛算~俺告你吧:估算月亮正午溫度是122度,實際是127度(更高些)~ -qiasini- 給 qiasini 發送悄悄話 (102 bytes) () 11/19/2011 postreply 16:21:36

那你為啥不吱聲?不利於自己?科學麵前咱們都是裸體,沒任何尊嚴可值得捍衛:) -qiasini- 給 qiasini 發送悄悄話 (0 bytes) () 11/19/2011 postreply 16:59:54

嗬嗬~解釋合理,俺接受:)謝謝~ -qiasini- 給 qiasini 發送悄悄話 (0 bytes) () 11/19/2011 postreply 17:05:13

這裏有Hasselblad 相機用於外空的曆史,可以看看了 -viewfinder- 給 viewfinder 發送悄悄話 viewfinder 的博客首頁 (120 bytes) () 11/19/2011 postreply 16:12:46

謝謝~有人畫出重點就好樂:)否則俺回頭慢慢看吧~ -qiasini- 給 qiasini 發送悄悄話 (0 bytes) () 11/19/2011 postreply 16:16:12

重點是原來相機機身是黑的,用於月麵的塗成銀色的勒 -viewfinder- 給 viewfinder 發送悄悄話 viewfinder 的博客首頁 (343 bytes) () 11/19/2011 postreply 16:20:25

謝謝介紹~這會有保溫效應的~其實保溫效應多大都可以算的~隻是俺不想再累了~ -qiasini- 給 qiasini 發送悄悄話 (0 bytes) () 11/19/2011 postreply 16:23:18

你怕累,我來算好了。小菜一碟,一塊蛋糕而已。 -TBz- 給 TBz 發送悄悄話 TBz 的博客首頁 (0 bytes) () 11/19/2011 postreply 17:48:53

謝謝~可省俺的心樂:)看你結果,俺會站在批判角度或欣賞角度的~ -qiasini- 給 qiasini 發送悄悄話 (0 bytes) () 11/19/2011 postreply 17:52:40

期盼!期盼!期盼! -iwbb- 給 iwbb 發送悄悄話 iwbb 的博客首頁 (0 bytes) () 11/19/2011 postreply 23:12:36

輕點是原來相機鏡頭是黑的,用於月麵的沒塗成銀色的還是黑的勒 -iwbb- 給 iwbb 發送悄悄話 iwbb 的博客首頁 (0 bytes) () 11/19/2011 postreply 16:27:31

嗬嗬,還真是:) -qiasini- 給 qiasini 發送悄悄話 (0 bytes) () 11/19/2011 postreply 16:29:18

黑塑料或橡膠在月亮上曬一下,溫度就sky is the limit啦! :-)) -iwbb- 給 iwbb 發送悄悄話 iwbb 的博客首頁 (0 bytes) () 11/19/2011 postreply 17:19:31

分析靠鋪~是為了美觀震撼打了小逆光~看看小石頭的暗影,相機背光麵應當很暗看不見的~ -qiasini- 給 qiasini 發送悄悄話 (72 bytes) () 11/20/2011 postreply 00:17:03

哎呀,你幹什麽嗎?咱想讓他們算算黑色鏡頭的溫度。得,這下他們不算了! -iwbb- 給 iwbb 發送悄悄話 iwbb 的博客首頁 (0 bytes) () 11/20/2011 postreply 05:55:29

溫度都差不多,黑色因吸收係數可能稍高,溫度高個十度左右~ -qiasini- 給 qiasini 發送悄悄話 (364 bytes) () 11/20/2011 postreply 11:35:46

我還是認為月亮表麵向月亮內部傳導很多滴熱量滴 -iwbb- 給 iwbb 發送悄悄話 iwbb 的博客首頁 (0 bytes) () 11/20/2011 postreply 13:03:16

那是~有溫度梯度~內部還往外回扣呢~ -qiasini- 給 qiasini 發送悄悄話 (0 bytes) () 11/20/2011 postreply 13:11:56

是個因素,但俺沒見人提起過。因此你得查資料或用太陽粒子輻射強度資料計算了。 -qiasini- 給 qiasini 發送悄悄話 (67 bytes) () 11/20/2011 postreply 13:30:32

對,但應該有個平均值可查到~航天人必須研究這個的~你試著找找? -qiasini- 給 qiasini 發送悄悄話 (0 bytes) () 11/20/2011 postreply 13:47:01

俺找到一些資料,但得煩請你折算: -qiasini- 給 qiasini 發送悄悄話 (297 bytes) () 11/20/2011 postreply 13:55:27

估算不計細節,俺給你估算一下: -qiasini- 給 qiasini 發送悄悄話 (245 bytes) () 11/20/2011 postreply 14:21:55
