Ob peb hnub dhau los, SpaceX tau ua tiav tiav xa ob tus neeg caij nkoj mus rau ISS siv Crew Dragon manned spacecraft. Tam sim no nws tau dhau los paub tias cov txheej txheem onboard ntawm SpaceX Falcon 9 foob pob hluav taws, uas tau siv los tso lub nkoj nrog cov neeg caij nkoj ntawm lub nkoj mus rau hauv qhov chaw, yog raws li Linux operating system.
Qhov xwm txheej no tseem ceeb rau ob qho laj thawj. Ua ntej, thawj zaug nyob rau hauv kaum xyoo, astronauts mus rau hauv qhov chaw los ntawm US av. Qhov thib ob, qhov kev tshaj tawm no yog thawj zaug hauv keeb kwm uas lub tuam txhab ntiag tug tau xa tib neeg mus rau qhov chaw.
Raws li cov ntaub ntawv muaj, cov txheej txheem onboard ntawm Falcon 9 tso lub tsheb tau khiav tawm ntawm Linux, uas tau teeb tsa ntawm peb lub khoos phis tawj rov qab nrog dual-core x86 processors. Lub software siv los tswj lub davhlau Falcon 9 yog sau rau hauv C / C ++ thiab khiav nyias ntawm txhua lub computer. Lub foob pob hluav taws tsis xav tau cov txheej txheem tshwj xeeb uas muaj kev ntseeg siab tiv thaiv hluav taws xob, txij li rov qab thawj theem tseem nyob hauv qhov chaw luv luv. Txhawm rau kom ntseeg tau tias kev lag luam txhim khu kev qha, kev rov ua dua tshiab muab los ntawm peb lub khoos phis tawj rov ua dua yog txaus.
Lub hauv paus tsis qhia meej tias cov txheej txheem twg SpaceX siv nyob rau hauv nws lub foob pob hluav taws, tab sis nws yuav zoo dua tias tsis yog cov kev daws teeb meem tshiab tshaj plaws thiab muaj txiaj ntsig zoo tshaj plaws, vim qhov no feem ntau siv. Piv txwv li, International Chaw Chaw Nres Nkoj tau siv Intel 80386SX processors nrog zaus ntawm 20 MHz los ntawm 1988. Cov kev daws teeb meem no tau siv los txhawb kev siv multiplexer thiab demultiplexer (C&C MDM), tab sis lawv tsis zoo rau lwm yam haujlwm. Nyob rau hauv lub neej txhua hnub, astronauts siv HP ZBook 15 laptops khiav Debian Linux, Scientific Linux thiab Windows 10 software platforms. Linux computers yog siv los ua terminals rau txuas mus rau C&C MDM, thaum lub qhov rais laptops yog siv rau saib xa ntawv thiab surfing lub network Internet thiab kev lom zem.
Cov lus tseem hais ntxiv tias ua ntej lub tsheb tso tawm, cov software thiab cov cuab yeej siv los tswj lub davhlau tau sim ntawm lub simulator uas muaj peev xwm simulating ntau yam xwm txheej, suav nrog cov xwm txheej ceev. Nws yog qhov tsim nyog tias Crew Dragon spacecraft tseem siv cov tshuab khiav ntawm Linux, nrog rau software sau hauv C ++. Raws li rau qhov kev sib tshuam nrog cov neeg caij nkoj sib cuam tshuam, nws yog lub vev xaib thov hauv JavaScript. Lub kov vaj huam sib luag siv rau kev ua haujlwm yog duplicated los ntawm lub laub-khawm interface thaum tsis ua haujlwm.
