How will Space X and Boeing company make sure NASA astronaut is safe?

20 thousand produce a standard. Commerce carries a person to carry the capsule that the project uses, for example CST-100 and DragonV2, needs supply works to be in charge of by these private companies almost. The business that SpaceX and Boeing want to satisfy NASA to make only holds 280 standards that the person sets in carriage project contract. NASA commerce flight develops central controller McAlister to state these standards basically involve safety and performance side, also do not meet to the requirement of Space X and Boeing company very strict. For instance, add up to guild regulation to make break down plans a system and can let astronaut hand use the software on operation aircraft for astronaut, but they did not stipulate how these systems run. McAlister says: "Such operation, designed a system to provide flexibility according to his means for privately owned company. Commerce carries a person to carry a project to be able to yield the level of our abolish low norms, allow privately owned to the company undertakes innovating and offer distinctive solution. " the standard that because need not worry about NASA heavy and complicated,McAlister thinks and frequent examination, this also was the working progress of SpaceX and Boeing company to offer advantage. NASA reachs spaceflight for privately owned company the contact is provided between the bureau, a job offers these contacts and company engineer the skill that they require. Spaceflight bureau asks to know the design of the company completely. McAlister divulge: "If the data with important important perhaps meeting needs a test, we have authority control case. " although communication, cooperation is very close, the aircraft is final it is vest in SpaceX and Boeing is not NASA. Commerce carries a person to carry a project to superintend strength to be able to cause safe problem not quite likely. January, the aerospace Advisory Committee on Safety that safety performance of project of the responsible NASA that monitor works says NASA was not them to provide detailed safe carriage data. After this, NASA strengthens the communication with ASAP, but the JosephDyer of naval lieutenant general that holds the position of advisory committee chairman still has concern. Dyer carries to sowing guest client (TheVerge) say: "We believe the stand or fall of executive strength depends on heading force. " as NASA a few crucial figures for example the affiliation of BillGerstenmaier of assistant administrator of center of NASA mankind exploration, dyer worries about safe problem no longer. He still says, must believe character harmony looks and he discovers notable is him is not open and transparent data information. Boeing is developing CST-100 capsule at present, be in charge of thinking aerospace carries astronaut break down to plan process business to carry a person to carry a project to ask the company satisfies standard of a few crucial technologies, if the classmate gives birth to need,check through the standard. Company whether through depending on oneself actual strength. To SpaceX and Boeing company, this means complex program. For example, all of computer science department that the company can differ 3 times in the equipment inside the aircraft, avoid to two systems malfunction when executive task. Although 3 systems malfunction, also want to ensure astronaut still has mothball resource to be able to control aircraft task process. Those who assure astronaut safety advocate the break down that the operating system is capsule plans a program. We were learned from SpaceX in June, a little steel bar can make heft many tons 500 rocket to fall in takeoff hour. NASA wants to if similar issue happens again,ensure, astronaut can be safe flee for one's life. To ensure astronaut is safe, spaceX configured break down to plan a system to be able to offer astronaut to be used in the flight. DragonV2 surface embedded small-sized machine namely SuperDraco, it can arrive at aerospace in the aircraft before, capsule is carried to escape when the rocket malfunctions. DragonV2 still deployed parachute to be able to bring back capsule safety the earth. The spokesman PhilLarson of SpaceX says: "With before system of break down tower is different, this device can help astronaut escape toward orbit. " May, spaceX carries out emissive break down successfully to operate experimental Boeing company to say they also have flee for his life similarly the system can offer astronaut to be used in the flight. If the aircraft malfunctions, boeing aircraft system can detect automatically a breakdown, meanwhile RocketdyneRS-88 machine can send place of safety region capsule. Boeing company carries person and ChrisFerguson of controller of task operation center to say, parachute can be started later. He still says, once advocate the machine malfunctions, operating system of flight break down but the for love or money moves. The plan that answers breakdown also prepares to end before the aircraft blasts off. Operating systems of these the break down that be called, they malfunction in rocket machine when astronaut from blast off frame take away. The flight flees for his life these machines in the system reach capsule area region of place of safety. Although these are safe the system is very similar, but the test that they accept is not same. SpaceX already revealed break down operating system May, plan to checked a flight to flee for one's life 2016 system. And Boeing company expresses to won't examine to stop among them before Feburary 2017 operating system. In addition, before capsule undertakes carrying person aviation first, boeing company did not release the information that has a test to operating system of flight break down. NASA thinks, because,this is Boeing more rely on at computer model. Because SpaceX has had the aircraft of similar DragonV2, so this company can do real test. NASA of probability risk assessment is forecasted will have casualty accidents happening, this kind of terrible calculation method is probability risk assessment (Probabilisticriskassessment) abbreviation PRA. It can be used at assessing the risk of sophisticated technology, the content that basically forecasts includes tripartite range: Potential systematic trouble, the form of breakdown happening, and brought result - also include to die of course. When the company undertakes probability risk is evaluated, need pays close attention to the mortality in the past, area of aircraft dependability, flight and other are relevant data. McAlister of NASA staff member says: "Imitate real flight test to need to undertake repeatedly sometimes. " these companies must prove capsule ensures when job of station of executive international space the survival rate of astronaut is achieved 99.

6% . Actually people is put in doubt all the time to PRA. For example, they did not consider the factor of human mistake. The expert thinks, it is absolutely impossible also that the catastrophic element of will all likelihood considers to go in, but the aero actor defect that they will launch to the analysis is very helpful. Although be put in a few blemish, photograph of PRA of commercial space flight is self-evident to the advantage of old test. Space shuttle astronaut breaks the average probability of couplet to be 1/80, the safety factor that presses this computation new capsule is 3 times of it. Colombian date and challenger date airship die brings shade is enveloping safe system, this also is one of reasons that new break down operating system exists. Ferguson says, this also is why capsule volume is minorrer - facilitate the orbit fragment in avoiding aerospace. Ferguson still says: "Although our technology obtained significant progress, but we did not gain complete victory, we cannot forget space shuttle to had claimed 15 fresh life. " although compare commerce to carry a person to carry project and space shuttle,be temporary, but very be necessary. SpaceX will in April 2016 the share tests Dragon capsule, boeing company will in April 2017 the share tests its CST-100 capsule. Carry a person to fly to undertake on 2017 formerly next time, although if congress does not approve the capital that place of spaceflight bureau project needs,NASA controller CharlesBolden says, carry a person to fly to be met soon first defer. The success that flies first can't prove the success of this project probably, we need dependability. So we need more flight jobs, and not just once. Only emissive task failure just knows the outcome of the test, also issue us to be able to detect in this kind of circumstance only the effect that gives safe system after all how. CNC Milling
