Cov kab lus dhau los ntawm lub ncauj lus no ua rau muaj kev sib tham kub heev. Yog li peb nthuav tawm lwm feem ntawm qhov tsis tshua muaj "qhov tseeb".

1. Cov foob pob hluav taws ya vertically nce

space myths xwb

Yog tias koj saib ib qho yeeb yaj kiab txog qhov chaw (piv txwv li, tib yam "Interstellar"), koj yuav pom tias lub foob pob hluav taws tsuas yog tshem tawm, nce siab dua thiab siab dua, txo qis siv theem - thiab tam sim no lawv nyob hauv orbit. Zoo heev, puas yog?

Dab tsi tiag. Yog hais tias koj cia li ya mus, sai los yog tom qab ntawd koj yuav khiav tawm ntawm cov roj thiab koj yuav poob rov qab rau lub ntiaj teb. Yuav kom nyob twj ywm nyob rau hauv lub orbit, lub spacecraft yuav tsum tau muab thawj qhov chaw tshaj tawm qhov chaw ceev - rau lub ntiaj teb nws yog 7,91 km / s. Tom qab ntawd nws yuav tig mus ncig lub ntiaj teb thiab tsis poob.

Nyob rau hauv kev muaj tiag, spaceships tsuas ya nce mus rau thawj ob peb vib nas this. Tom qab ntawd lawv pib qaij, maj mam nce kab rov tav. Yog li ntawd, lub davhlau tsis nyob rau hauv ib txoj kab ncaj nraim, tab sis nyob rau hauv ib tug arc. Ua tibzoo saib CRS-4 daim duab ntawm ib qho kev raug foob pob hluav taws ntev ntev thiab pom qhov tseeb trajectory.

2. Qhov chaw khib nyiab yog qhov txaus ntshai heev

space myths xwb
space myths xwb

Zaj duab xis "Lub ntiajteb txawj nqus" qhia meej tias qhov chaw khib nyiab txaus ntshai yog dab tsi. Cov kwj ntawm me me ntawm cov satellites puas tau nthuav tawm thawj zaug Hubble, tom qab ntawd ISS thiab, thaum kawg, Tiangong-1, thiab Sandra Bullock tau txais kev cawmdim los ntawm qhov txuj ci tseem ceeb.

US Space Observation Network tshaj tawm rau Orbital Debris, UCS Satellite Database, Qhov chaw khib nyiab los ntawm cov lej uas tam sim no muaj txog 20,000 cov khoom cuav hauv lub orbit: 2,218 cov satellites nquag thiab ntau dua 128 lab daim ntawm qhov chaw khib nyiab!

Thiab zoo li qhov no tsis txaus! Elon Musk npaj siab SpaceX Xav Launch 12,000 Satellites los tso 12,000 Starlink satellites rau hauv qhov chaw kom muab lub ntiaj teb pheej yig internet. Lub sij hawm tsis nyob deb thaum lub ntiaj teb yuav nyob ib puag ncig los ntawm ib txheej ntawm orbital khib nyiab, thiab qhov chaw ya davhlau yuav ua tsis tau.

Dab tsi tiag. Qhov txaus ntshai ntawm qhov chaw khib nyiab yog me ntsis exaggerated. Piv txwv li, rau ISS, qhov kev pheej hmoo ntawm kev sib tsoo nrog ib yam dab tsi yog ntsuas los ntawm Chaw Nyab Xeeb Tsis Muaj Teeb Meem: Lub Rooj Sib Tham 7th IAASS, Chaw Cai Lij Choj: Cov Ntaub Ntawv Tseem Ceeb, Kev Nyuaj Siab ntawm Orbital Debris thiab Tiv Thaiv NASA Space Assets los ntawm Satellite Collisions ntawm 1 / 10,000. “Tus txiv neej cov khoom khib nyiab loj tau taug qab tau yooj yim thiab zam tau yooj yim.

Thaum nyob rau hauv cov yeeb yaj kiab Astronaut hu ua peb cov lus dab neeg nrov tshaj plaws txog qhov chaw, qhia tias qhov chaw nres tsheb ya li cas, thaum lub sijhawm kawg dodging fragments rushing ntawm nws, qhov no yog qhov tsis muaj tseeb.

Alexander Lazutkin cosmonaut

Thaum kawg, qhov kawg kev sib tsoo ntawm lub satellite nrog qhov chaw khib nyiab tau tshwm sim hauv Asmeskas. Satellite Destroyed nyob rau hauv qhov chaw sib tsoo hauv 2009, yog li koj tuaj yeem pom ntawm koj tus kheej tias qhov no yog qhov xwm txheej tsawg heev. Qhov chaw nyob ze-Lub Ntiaj Teb yog qhov loj, thiab txoj hauv kev ntawm kev sib tsoo nrog cov seem ntawm lub dav hlau nyob hauv nws tsawg heev. Yog li no daim duab ESA ntawm Space Debris tsuas yog tus kws kos duab txoj kev npau suav xwb.

Raws li Elon Musk lub satellites, lawv ya ntawm qhov siab qis heev. Lawv yuav tuaj yeem nyob hauv qhov chaw tsis pub dhau tsib xyoos, thiab tom qab ntawd lawv yuav tawm ntawm lub voj voog thiab hlawv FCC pom zoo SpaceX txoj kev npaj ua haujlwm Starlink satellites ntawm qhov siab qis hauv qhov chaw tsis muaj kab. Txawm tias muaj tseeb hais tias txhua "microsatellite" los ntawm ib pob ntawm 60 daim (thiab qhov no yog ntau npaum li cas Falcon 9 tso rau hauv orbit) Starlink Lub Hom Phiaj hnyav 260 kg.

Yog li tsis txhob txhawj, qhov chaw khib nyiab tsis yog ze li txaus ntshai raws li feem ntau ntseeg.

3. Peb yuav tsis ya mus rau Mars vim hluav taws xob

space myths xwb
space myths xwb

Ntau tus tsis ntseeg txog cov phiaj xwm kom kov yeej Mars los ntawm tib Elon Musk, thiab ntawm no yog vim li cas. Qhov chaw muaj hluav taws xob puv. Nws lub hauv paus tseem ceeb hauv peb lub cev yog Lub Hnub, tab sis nws kuj tuaj txog ntawm cov hnub qub nyob deb. Nyob rau hauv lub ntiaj teb, peb muaj kev tiv thaiv los ntawm ib tug magnetic teb, tab sis nyob rau hauv qhib qhov chaw thiab nyob rau Mars tsis muaj xws li kev tiv thaiv. Yog li thawj tus neeg nyob hauv Martian yuav inevitably tuag.

Nws yog qhov coj txawv txawv uas Musk tsis xav txog nws, tab sis nws tsis yog tus kws tshaj lij Rogozin tsis ntseeg SpaceX lub peev xwm los dhau lub Lavxias Federation hauv foob pob hluav taws, txoj cai?

Dab tsi tiag. NASA's MARS Odyssey sojntsuam siv lub cuab yeej hu ua MARIE (Martian Radiation Experiment), nrog rau Curiosity rover, kawm MARS Odyssey, Thawj qhov kev ntsuas hluav taws xob los ntawm Mars, Kev Ntsuas Hluav Taws Xob Hluav Taws Xob hauv Kev Hloov mus rau Mars ntawm Mars Science Laboratory hluav taws xob ib puag ncig hauv Mars orbit. Nws muab tawm tias qhov hluav taws xob tsis tu ncua muaj 2.5 npaug siab dua li ntawm ISS. Nyob rau saum npoo, cov phonite tsis muaj zog: qhov nruab nrab koob yog li 0.67 millisievert (mSv) (rau kev sib piv: hauv orbit - 1.8 mSv).

Qhov no muaj ntau, tab sis nws tsis tuaj yeem hais tias cov neeg caij nkoj uas ya mus rau Mars yeej yuav tuag. NASA hais tias Mars 'Nto Radiation Ib puag ncig ntsuas nrog Mars Science Laboratory's Curiosity Rover, Koj Yuav Tau Txais Radiation Ntau npaum li cas Thaum Lub Hom Phiaj Mars ?, Puas Yog Radiation ntawm Mars? tias yog tib neeg siv 500 hnub hauv ntiaj teb no, ntxiv rau lawv siv 180 hnub ntawm txoj kev ntawd thiab tib tus nqi rov qab los, cov hluav taws xob tom qab cosmic yuav ua rau lawv muaj kev pheej hmoo mob qog noj ntshav los ntawm 5%. Rau kev sib piv: ntawm ISS, qhov kev pheej hmoo yog 3%. Feem ntau, cov astronauts, txawm tias cov uas ya mus rau lub hli, tsis muaj qhov tshwm sim loj heev. Contrapositive logic qhia tias qhov chaw hluav taws xob tsis muaj kev cuam tshuam rau kev tuag ntawm US astronauts thiab Soviet thiab Lavxias teb sab cosmonauts ntawm hluav taws xob.

NASA muaj ntau txoj haujlwm los tiv thaiv lub dav hlau los ntawm hluav taws xob - piv txwv li, tiv thaiv cov neeg coob nrog cov tso tsheb hlau luam tshwj xeeb tiag tiag Martians: Yuav ua li cas tiv thaiv astronauts los ntawm Chaw Radiation ntawm Mars nrog dej. Kev ya mus rau Mars yuav tsis zoo rau kev noj qab haus huv, tab sis tib neeg mus rau kev tshawb fawb thiab kev txi zoo.

4. Lub Tuam Tsev Loj Loj ntawm Tuam Tshoj pom los ntawm lub hli

Xws li ib tug funny "qhov tseeb" yog hais nyob rau hauv ntau cov ntawv xov xwm nrov. Lub Tuam Tsev Loj Loj ntawm Tuam Tshoj tsuas yog tib neeg tsim khoom pom los ntawm lub hli nrog qhov muag liab qab. Ua li ntawd.

Dab tsi tiag. Ntawm no yog ib daim duab ntawm Apollo 11 Lub Hom Phiaj Duab - Saib lub hli Limb, nrog lub ntiaj teb nyob rau hauv qab ntug ntawm lub ntiaj teb, coj los ntawm saum npoo ntawm lub hli thaum lub sij hawm Apollo 11 lub hom phiaj. Los yog ntawm no yog lwm daim duab ntawm Crescent Earth thiab US Chij coj thaum lub sij hawm tsaws ntawm Apollo 17 neeg coob. Koj puas xav tias koj tuaj yeem pom qee yam ntawm qhov deb ntawm 384,400 km?

NASA tau tshaj tawm Tuam Tshoj lub Phab Ntsa Tsawg Zoo Tshaj Plaws hauv Saib los ntawm Chaw Uas Suav Phab Ntsa tsis pom los ntawm lub hli.

Qhov tsuas yog qhov uas koj tuaj yeem pom ntawm lub hli yog qhov zoo nkauj kheej kheej, feem ntau yog dawb, nrog cov xim xiav thiab daj, nrog rau me ntsis ntsuab. Tsis muaj cov khoom tsim los ntawm tib neeg yuav pom ntawm qhov ntsuas no.

Alan Bean, Apollo 12 astronaut

Qee lub sij hawm lub hli tsis tau hais thiab lawv tsuas hais tias: "Lub Tuam Tsev Loj Loj ntawm Tuam Tshoj yog tib yam khoom uas tuaj yeem pom ntawm qhov chaw." Thiab los ntawm qhov ntawd, nyob rau hauv txoj kev xav, tsis tsuas yog cov phab ntsa pom xwb: cov astronauts ntawm ISS daim ntawv ceeb toom thiab yees duab nroog.

Tab sis Suav cosmonaut Yang Liwei nyob rau hauv nws cov duab ISS010 - E - 8497 yeej tsis muaj peev xwm ntes tau phab ntsa. Txawm hais tias tsawg kawg nws yog tam sim no ntawm Great Wall of China ntawm cov duab radar. Yog li qhov no yog deb ntawm qhov pom pom tshaj plaws ntawm lub ntiaj teb.

5. Cov shuttles yog heev unreliable

Hauv 2011, NASA cov thawj coj pom zoo STS-135 lub hom phiaj npaj rau lub Rau Hli 28, 2011 tau pib lub Atlantis shuttle. Txij thaum ntawd los, cov neeg Amelikas tau taug kev mus rau hauv qhov chaw, yuav cov rooj zaum ntawm Lavxias Soyuz, thiab lawv cov neeg ua haujlwm Dragon Crew thiab Starliner yuav tsum pib ya xwb xyoo no.

Vim li cas shuttles - thiaj li nce thiab rov siv tau - tso tseg? Lawm, vim lawv tsis tshua muaj kev ntseeg siab thiab kev sib tsoo tus nqi. Nws tsis muaj lus tso dag - thaum lub sijhawm lub davhlau ya davhlau, Tus Kws Ua Haujlwm uas tau ceeb toom ntawm 1986 Challenger kev puas tsuaj tseem racked nrog kev ua txhaum, peb xyoos dhau los, Columbia Crew Survival Investigation Report 14 tus neeg tuag rau lawv.

Dab tsi tiag. Tsuas yog ob peb tus lej. Thoob plaws hauv nws keeb kwm, tsib lub shuttles ua rau NASA's Space Shuttle Los Ntawm Cov Naj Npawb: 30 Xyoos ntawm Spaceflight Icon 135 lub davhlau, ntawm ob qhov kawg hauv kev puas tsuaj: 10 lub davhlau rau Challenger thiab 28th rau Columbia yog qhov kawg.

Tab sis, rau kev sib piv, Soyuz spacecraft rau 2011 ua 116 flights, ob ntawm uas tau xaus nyob rau hauv kev sib tsoo.

Lub shuttles coj NASA lub Chaw Shuttle Los Ntawm Cov Naj Npawb: 30 Xyoos ntawm Spaceflight Icon mus rau qhov chaw 355 tus neeg los ntawm ntau lub tebchaws, thiab rov qab xa lawv 789 (lawv feem ntau coj cov neeg ua haujlwm uas ya mus rau Soyuz los ntawm ISS). Nyob rau hauv tag nrho, lawv tau siv 8,280 hnub nyob rau hauv orbit thiab coj mus rau hauv qhov chaw 1,593,759 kg ntawm payload thiab 180 satellites, thiab txawm tsim feem ntau ntawm ISS.

Peb tso tseg cov shuttles vim lawv cov nqi siab. Tus nqi ntawm qhov kev pab cuam 30 xyoo yog Space Shuttle Era Facts $ 113.7 billion.

Txhawm rau tsav mus rau hauv lub voj voog tsis muaj dab tsi, muaj peev xwm xa mus txog yim tus neeg thiab 24 tons ntawm cov khoom thauj hauv ib qho kev xa tawm, ua rau kim heev txawm tias NASA.

6. "Buran" tuaj yeem tawm ntawm sab nraub qaum ntawm An-225

Los ntawm txoj kev, ntau ntxiv txog cov shuttles. Txhua leej txhua tus paub tias lub USSR muaj nws tus kheej shuttle hu ua "Buran". Nws tau ua nws thawj zaug thiab tsuas yog lub dav hlau loj tshaj plaws rau lub ntiaj teb thiab tsaws tsis muaj neeg tsav tsheb hauv xyoo 1988.

Tsis zoo li cov shuttles uas siv qhov chaw Shuttle. Keeb kwm ntawm National Space Transportation System: Thawj 100 Lub Hom Phiaj rov qab siv tau cov roj boosters, "Buran" tau ya mus rau lub foob pob hluav taws hnyav hnyav "Energia", uas yog irretrievably poob TRIUMPH THIAB LUB SIJ HAWM NTAWM "ENERGY", Soviet Buran Space Shuttle, Soviet daim ntawv ntawm lub shuttle - reusable chaw shuttle ib tug system nrog ib tug OS-120 orbital aircraft nyob rau hauv kev kawm.

Tab sis "Buran" muaj txhua txoj hauv kev los ua pheej yig dua li shuttles. Tom qab tag nrho, nws tau npaj yuav tso nws mus rau hauv qhov chaw, nqa nws mus rau saum huab cua nyob rau sab nraum qab ntawm An-225 - tus naas ej Mriya. Nws yog ntau npaum li cas thiab economical.

Dab tsi tiag."Buran" tsis paub yuav ua li cas tshem tawm. Cov neeg uas tuaj nrog lub tsheb kauj vab no, pom tau tias, tsis meej pem nrog qhov projected, tab sis tso tseg lub dav hlau "Spiral" Air-Orbital Plane (VOS) "Kauv". Lub Mriya yuav tsis muaj qhov ceev thiab lub zog xa ib lub dav hlau loj rau hauv suborbital ya davhlau.

Lub tswvyim hais ua dabneeg tau yug los ntawm daim duab ntawm Antonov An-225 Mriya - Antonov Design Bureau, qhov twg Buran tau thauj mus rau sab nraum qab ntawm An-225. Lub Shuttle hauv Mate - Demate Device raug thauj mus rau SCA - 747 - Sab Saib thiab shuttles ntawm Boeing 747SCA tau thauj tib txoj kev.

7. Astronauts noj txhua yam ntawm cov hlab

Txhua tus neeg uas nyiam me ntsis hauv astronautics paub tias koj tsis tuaj yeem noj ntawm lub phaj hauv qhov chaw tsis muaj cua: cov zaub mov hauv lub xeev tsis muaj qhov hnyav tau tawg thoob plaws hauv lub nkoj. Yog li ntawd, astronauts noj los ntawm cov raj zoo ib yam li cov muag tshuaj txhuam hniav.

Dab tsi tiag. Nws yeej zoo li ntawd ua ntej. Gagarin, piv txwv li, noj cov ntsiab lus ntawm peb lub raj ntawm Keeb Kwm ntawm Kev Noj Qab Haus Huv hauv Chaw Dav Hlau: Cov Txheej Txheem hauv lub voj voog: ob qho tib si nrog cov nqaij hauv av, ib qho nrog chocolate. Cov neeg Amelikas kuj tau noj Food For Space Flight los ntawm cov raj, thiab kuj tau noj cov zaub mov zoo hauv daim ntawv me me los ntawm cov thawv yas.

Thiab cov neeg ua haujlwm Gemini 3 tau coj Gemini 3 Fact Sheet, Gemini 3 nrog corned nqaij nyug qhaub cij nrog lawv thiab npog lub nkoj nrog crumbs, uas ua rau NASA tsis pom zoo.

Tab sis tam sim no cov raj yuav luag tsis siv (tsuas yog rau seasonings thiab kua txiv hmab txiv ntoo). Hloov chaw, astronauts noj keeb kwm ntawm Khoom noj khoom haus nyob rau hauv Space Flight: Txheej txheem cej luam, Kev soj ntsuam ntawm lub sij hawm ntev ruaj khov ntawm Retort Pouch Foods los txhawb Extended Duration Spaceflight, Space Food, Space Food yooj yim zaub mov, txiv hmab txiv ntoo, khov-dried zaub mov los ntawm lub hnab thiab cov kaus poom zaub mov. Thiab ntawm ISS, Mexican tortillas yog nrov ntawm Chris Hadfield's Space Kitchen.

8. Nyob rau hauv lub qhov dub, koj tuaj yeem pom qhov kawg ntawm lub ntiaj teb
