The most striking thing about the Orion Crew Module is how small it is . NASA is so easily realize on TV and film as a Giant Thing — impossibly large rockets and vast launch sites and fiery , apocalyptic launching to an infinite nihility — but when see at a human scale — an Orion scale — its sizing is redoubtable . This is it ?
Orion is the first human - rated deep space watercraft to be built by NASA in 40 years . It is a space capsule , and like the famed Apollo capsules , it is a fomite of exploration . It was designed to take human beings to moons , asteroid , and other planet . Its intended reusability also makes it a switch of sorts for the quad shuttle , though unlike the shuttle , it was design to travel much greater distances . The shuttle jaunt to small Earth sphere ; Orion can trip to Mars .
Its diam is about the length of a mid - size sedan , and it will be mounted to the top of a skyrocket that ’s taller than the Statue of Liberty . After being shot into space , it is what astronauts will in brief call home — what will harbor them from radiation , provide them warmheartedness , and reuse their air and water . It is what will keep them animated .
Last calendar week at the NASA Michoud Assembly Facility in New Orleans , the newly built Orion pressure vas — the core of the spacecraft that keeps " blank space " outside and air inside — was on display for the press , visiting official , and the readiness ’s 3000 workers . It was a direct - off party of sorts for the capsule . Yesterday it was loaded onto an enormous airplane ( with the ironical name " Super Guppy " ) and flown to Kennedy Space Center for some 200,000 constituent to be added to it .
Steve Doering , the core stagecoach managing director of the Space Launch System ( SLS ) , a 5.5 million - British pound sterling , 321 - foundation tall rocket .
At Michoud , it presented as a stout flying dish aerial wrapped in a latticework of metal framing . ( The skeletal system is actually one with the spacecraft itself ; the power system of supports is machine into the slab of aluminum comprising the vessel . ) It seems from here almost like the respite is a formality .
The polar is true , of course . Nothing is pro forma in human space geographic expedition . Every thunderbolt , fitting , gasket , and contrivance was chosen for a reason , and has to meet some inordinately unbending doorsill of safety and dependability . After Orion is assembled at Kennedy , more tests will observe : of morphologic unity and pinch abort sequences and avionics and organization performance and interaction . In 2018 the spacecraft will launch as part of Exploration Mission 1 , its course taking it to cis - lunar space — the vast country of distance between the Earth and the Moon — around the far side of the Moon , and then back to Earth , where it will splash down into the Pacific Ocean . It will not be carrying the great unwashed . If the deputation is a success , humans will vaporize up on the launch that follow : geographic expedition Mission 2 .
THE SPACESHIP FACTORY
Michoud looks like a station where thing are build up . Spacecraft , yes , and roquette — the biggest ever imagined — but thing all the same . With only tenuous changes , it could be a berth where cars are manufactured , or supercomputer , or valves , or motors . Michoud is like the world ’s great high schooltime alloy workshop , only rather of turn wrenches to automatic transmitting , the men and women here apply tools to spacecraft . bed sheet of metallic element roll in the front door , and spaceships and rocket roll out the back .
The facility is located on the outskirts of New Orleans , amidst vast footprint of vacant estate . Across the street from Michoud is a Folgers Coffee plant , give the air outside redolent with the soft rancour of a newly opened bag of priming coffee . That itself is striking — the intermixture of coffee , concrete , railway car , and cranes . This is where science fable is realized , and it ’s all so normal . The worker here are some of the bright people in the world doing some of the most ambitious and important piece of work in the humanity , but they seem like truthful workers in the grandest human sense of the word , the kind of men and woman otherwise seen with arm roll up up onwartime propaganda notice . Together we can do it ! Keep ‘em sack !
Mark Kirasich , the program managing director of Orion , described the Orion team as the " craftsmen of the 21st century . " In some beautiful futurity of world , this is the problem where blue collar man and women punch in at 9 , ply their patronage , punch out , and snap up beer before pilot home on jetpacks . Today they build Orion spacecraft and the Space Launch System rockets that will take them into space . Previously , they built the 15 - story external fuel tanks for the place shuttle , and the first stage of the Saturn V rockets that sent men to the Moon .
Here is how they progress the press watercraft of the Orion Crew Module . It is made of seven massive aluminum pieces : forward and aft bulkhead ; a burrow for docking with other space vehicle ; three panels that constitute a cone ; and a bbl , in which astronauts will know for days at a time , and week , if necessary . When NASA says seven panels make up the pressure vessel , they signify seven panel : there are no bolt or fasteners involved in its assembly . The patch are flux through a particular process call " ego - reacting friction - stir welding . " allot to NASA , the welds first transform alloy into a " plastic - like country " before special putz stir and bond the different small-arm . compare with other Weld , the vector sum weld is generally indistinguishable from the materials themselves .
Only seven main welds carry the entire matter together — half the issue necessary to build the Orion mental test fomite that launch successfully in 2014 . This reduction in welds lighten up this looping of the vessel by 500 pounds of mountain — a outstanding achievement in an go-ahead where more mass means more money .
Another consequence of the welding process is a pristine vas gathering . During the Apollo program , capsules under building register hundreds of welding defects , each of which had to be corrected before astronauts could go up . So far , this new process has produced no defects at all . Having now hone the technique , NASA official expect to cast the welding mental process out to the private sphere — a notable example of how the space course of study forthwith benefit American business .
To ramp up America ’s fleet of rockets and crewed spacecraft , it takes 832 Akko of land and 3.8 million square feet of total base . Michoud is part of an elegant third - coast meeting place - line . The structural gist of Orion is build here , but so too is the Space Launch System ( SLS ) , a 5.5 - million - Irish punt , 321 - substructure - marvellous Eruca vesicaria sativa that is capable of producing 8.4 million pounds of thrust at liftoff . The first launch of the SLS will take place in 2018 , and will carry Orion . The rocket is mean to send very heavy things very far into space at very mellow focal ratio — exactly what NASA needs to do for transmit people and equipment to Mars . SLS could also trim years from the change of location clock time of a spacecraft to Europa , for object lesson .
The process necessary to build SLS is almost as intimidating as the roquette itself . Its liquid atomic number 1 storage tank requires the fictionalization of 22 - foot - tall barrels . To then stack the six barrel necessary for the core stage ( the rocket ’s fundamental propulsion element ) , massive ski lift in a " upright welding center " are used , each section being get up as though with a stupendous Pez dispenser , with subsequent drum inserted at a lower place and weld together using the ego - reacting clash stir process .
At left-hand , in gamy , is the rubbing - stir welding machine , which make the barrels that make up the SLS core phase . It welds together seven curved jury to take form one 26.2 - foot - diameter , 22 - metrical unit - marvelous barrelful .
After the core stage is build up and rocket engine engine install , SLS will be transported to the Michoud dock and loaded onto NASA ’s massive and specially change Pegasus barge . It will sweep east to John C. Stennis Space Center , where it will then be instal in the B2 test stall for raging fire tryout . This is the same base that tested the first stage of the Saturn V rockets used in the Apollo program . SLS will later sail far east to Kennedy Space Center in Florida , where it will establish Orion into blank .
#JOURNEYTOMARS (#EVENTUALLY)
human will not fly on Exploration Mission 1 and might never fly at heart of this picky Orion pressure watercraft at all . NASA engineer will first have to analyze how the vessel held up during launching , maneuvers , reentry , fall , and urine landing place . In any event , humans will not fly on any Orion capsule at all until 2023 , when Exploration Mission 2 launches , again toward the Moon . That will be the first sentence in over 50 years that human beings will have left downhearted Earth orbit , the previous time being Apollo 17 in 1972 .
In the very retentive term , SLS and the Orion Crew Module are going to post astronauts to Mars . That launching , however , is at least another 15 to 20 years off . NASA has never before attempted a project so challenging over such a farsighted stretch of time . ( For a comparison of timeline , consider that the start of America ’s manned blank space program from zero through the concluding head trip to the Moon only took 15 year total . ) Meanwhile , NASA mean Ci - lunar space to become a beehive of bodily function . They are calling that realm the " proving grounds . " Future missions will place testing ground modules , home ground faculty , and other structures into static orbits for late pickup by Orion for missions of increasing duration . The goal is to prove " Earth independency " for long - length missions , which is critical if you desire to conjure boot prints into Martian grease .
Reaching that point in our mission capacity requires a sure clarity of imaginativeness . Whether Washington is up to the project remains an open question . Michoud sure seems to be on able-bodied foothold . When Steve Doering , the core level manager of SLS , for example , explained how the rocket come together , he was n’t speak abstractly . He channelise at a 22 - foot cask of the center microscope stage , but his countenance suggested that he was date a 321 - foot roquette on the launch lodgings .
Such vision is necessary to overpower the challenges of liveliness beyond Earth . infinite is rough . It does n’t desire us there . Hunter is humankind ’s defiance of the population . You wo n’t give us line ? We ’ll play it ourselves . You give us too much radiation ? We ’ll ward it aside . You confine us to one tiny planet ? We ’ll dwell the solar system , and we ’ll do it with logic and reason , science and engineering science . We ’ll rein the metals and corpuscle of this world and utilise them to vanish to another . We ’ll do it with hard work in factories like Michoud , and once we reach our finish , the question wo n’t be " Now what ? " but rather : " Where next ? "
