I-NASA ikhetha ngokucophelela ubuchwepheshe bemisebenzi yayo ukuqinisekisa ukusebenza kwayo ezimweni ezimbi kakhulu zasemkhathini. Le nhlangano isanda kushicilela "Imiphumela Yokuhlolwa Kwekhamera Ephathwayo Yokuqala." Ukuhlolwa kwenziwa ngo-2022. Umbiko uhlola ukusebenza kwamakhamera e-Canon EOS R5, Nikon D6, kanye ne-Nikon Z7II angakashintshwa ezimweni eziseduze kakhulu nesikhala ngangokunokwenzeka.
Amakhamera e-Canon R5 kanye ne-Nikon D6 amelana nokuhlolwa kwe-vacuum futhi asebenza emazingeni okushisa asukela ku--30°C kuya ku-+40°C. I-NASA iphawule ukuthi womabili amakhamera abonise "ukusebenza okufanayo" kuleli banga lokushisa. Ngaphambi kokuhlola, amakhamera kanye nemishini ehlobene nawo ashiswa ku-50°C amahora angu-72 ukuze kususwe ama-volatiles ngaphambi kokuhlola i-vacuum. Amakhamera abe esefakwa endlini elawulwa ukushisa ngaphakathi kwegumbi le-vacuum, kwase kusetshenziswa i-Wi-Fi ne-Bluetooth ukulawula ukuthwebula izithombe namavidiyo.
Amakhamera ahlolwe ngezindlela ezinganyakazi nezevidiyo, yize i-D6, ngokungafani ne-R5, ingazange ihlolwe ngokugcwele. I-R5 yaqopha ividiyo yaze yashisa kakhulu yaze yacima, ngemva kwalokho yanikwa isikhathi sokupholisa imizuzu emihlanu ngaphambi kokuba kuqhubeke ukuhlolwa. Abacwaningi abazange baphinde baqhube ukuhlolwa kwevidiyo ku-D6 ngenxa yokuthi kungenzeka ukuthi balahlekelwe ukuxhumana nekhamera. Noma kunjalo, onjiniyela be-NASA babheka i-R5 kanye ne-D6 njengezifanele ukusetshenziswa esikhaleni, kanye nesaziso sokuthi ukusebenza kwevidiyo ye-D6 akuzange kufundwe ngemininingwane enjalo.
I-Nikon Z7II, ngokungafani ne-D6, yehlulekile ukuphumelela ukuhlolwa kwezinga lokushisa eliphelele. Ngokusho kombiko, yayisebenza endaweni engenalutho ekamelweni lokushisa, kodwa emazingeni okushisa aphezulu, yalahlekelwa uxhumano ngemva kokuqopha ividiyo futhi ayizange ikwazi ukuxhuma kabusha. Ikhamera ayizange ihluleke ngokuphelele, kodwa yabhekwa njengengathembekile.
Lapho kuhlolwa amakhamera e-D6 kanye ne-R5, afakwa ngaphansi kwezimo ezihlukile kancane - i-D6 yayilungiselelwe ukuthwebula izithombe ze-RAW kanye ne-JPEG, kuyilapho i-R5 "yadlula lokhu kulungiselelwa ngesikhathi sokulungiselela" futhi yaqopha amafayela e-JPEG kuphela.
Ngaphezu kokuhlolwa kwekhamera, umbiko ofanayo wethula imiphumela yokuhlolwa kwemisebe yemikhiqizo emine yamakhadi e-CFexpress: i-Lexar, i-SanDisk, i-ProGrade, ne-Sony. Akukho neyodwa yamakhadi ehlulekile ngokuphelele; i-NASA ithi amaphutha esikhashana ahlobene nemisebe axazululwe ngokusetha kabusha amakhadi. Ikhadi le-SanDisk lavela njengelithandwa kakhulu yi-NASA, kodwa abahloli bagcizelele ukuthi imiphumela incike kuzilungiselelo zokuhlolwa eziqondile kanye nobukhulu bomsebe futhi akufanele kubhekwe njengesincomo sokuthenga.
Lo mbiko ka-2022 uthakazelisa kakhulu uma kubhekwa umsebenzi we-NASA kamuva ekhamera ekhethekile yenyanga. Ngo-2024, i-NASA yashicilela iphepha mayelana nokuhlola ikhamera yezentengiselwano eguquliwe yendawo yenyanga. Leli phepha laphetha ngokuthi ikhamera kanye nohlelo lwayo lokuvikela ukushisa kwaqhubeka nokusebenza ngaphansi kwezimo eziningi ezilingisiwe, kodwa ukugqwala esikrinini se-LCD kanye nokushisa ngokweqile kwabonwa ngaphansi kwezimo ezimbi kakhulu.
Ikhamera yenyanga ephathekayo yamanje ye-NASA esebenziseka kalula isekelwe ku-Nikon Z9 eguquliwe enamalensi e-Nikkor, ingubo yokuvikela yokushisa, izinto zikagesi eziguquliwe, kanye nokubamba okukhethekile kokusetshenziswa ngamagilavu e-spacesuit.
