(Journalist): So you are confident that you will return to Earth?
(José Jiménez): Yes, sure. But how deep under it - still do not know.
(Journalist): But the designers have given you something to stop your fall?
(José Jiménez): Of course. Nev. Blockquote> And a Genesis hit the list of jokes because wafers, which are considered very fragile survived such a blow. Of course, the task of retrieving samples greatly complicate sand Utah, debris and liquids if the probe, but some interesting scientific results - data on the isotopes of argon and neon allowed to drop a few theories about the origin of the sun and detected the increased concentration of the isotope oxygen-16, still waiting for his explanation .
By the way, Murphy's Law Murphy himself formulated after found accelerometers mounted backwards on the bench for the study of congestion.
It would be better h4> The tetralogy BE Chertok "Rockets and People" are two complementary joke. The situation first - in preparation for the launch of communications satellite "Molniya» discovered damage to the insulation. Bars antennas further wrapped vinyl chloride tape, which was frozen in space, and did not give zakamenela reveal antenna. The situation is the second - successfully tested the valve was disassembled, and it revealed the absence of a single part. Detail installed valve gathered, as expected, repeat the test and get a nasty remark - fully assembled valve with all the details acquired flaw that had to eliminate.
A similar thing happened in the United States. Ships "Gemini" had to be joined with a special target - upper stage "Agena" with docking station. But before the start of "Gemini 9A" target orbit did not come out because of the accident launch vehicle. This case was a reserve - a simplified target ATDA without fuel, but with a docking station. "Agen" to start normally prepared engineers at Lockheed, but just "Adzheny" on this start was not, engineers Lockheed, despite the protests of themselves and members of NASA, from the start removed and ATDA were installed engineers McDonnell, who was engaged in rocket Booster. Solving unusual for them to where the ends of the cords to remove the fixing halves of the fairing, engineers McDonnell tape strapped them into a seemingly suitable place - under the fairings explosive bolts. As a result, after the explosion explosive bolts in the space cords are not left in the direction, and fixed fairing halves in half-open position. According to telemetry, this situation was not visible, so the astronauts flew dock got a nasty surprise:
Docked with the "angry alligator" was impossible. The set of equipment of the ship were surgical scissors, and cut the cords have suggested the astronauts came out in open space. On the ground, we carried out the test, which showed that it is theoretically possible, but ATDA had a lot of sharp edges. Besides ATDA slowly revolved. After some discussion, the PMU attempts to rectify the situation banned. Astronauts limited rapprochement with ATDA and flyby it at close range:
It is here h4> Murphy's Law also states that, if you can take the cable length and inappropriate to install the wrong slot, it will be done. Anecdotal case occurred at the dawn of the US manned space program. Unmanned mission Mercury-Redstone 1 made as a joke evil tongues, desyatisantimetrovyh flight:
What happened? At the start of the rocket from it were two separate cables - power and control. However, the control cable was longer than necessary - get it with live missiles Redstone. Cable curved and fixed, hoping that this will be enough. Not enough - fasteners were weak, and when the rocket has been raised in the air, control cable had separated after the power cord. As a result of a rocket by 29 milliseconds lost ground to the power cord. Current went through the relay, normally triggered at the end of the flight, and set it. Engine switched off, the rocket fell back to the start, unable to rise high and therefore sat on starting construction without damage. At the end of the active portion of the recovery system was discharged, she flew to the side. System separation is not included - it was waiting for weightlessness, and the accelerometer showed an honest one "is" normal for standing on the launch pad. The ship worked automatic parachute, and, according to the barometric altimeter (height less than 3 km) threw a parachute. After 30 seconds, do not "feel" the tension straps of the parachute, emissions and automatic reserve parachute.
MCC was in a difficult situation. At the start stood fully fueled rocket. The slightest gust of wind - filled with parachutes, and the missile fell on its side. To get close to her, to even cut the parachutes, you can not - no one can guarantee the safety of people. Some hotheads in the MCC even offered to shoot at tanks with a rifle to punch a hole to drain components. Victory for common sense - a rocket just left on the clock to its batteries are exhausted. Lucky - these days there was no wind, after the battery discharge chutes cut and rocket successfully took off from the start.
A similar situation occurred during the flight "Apollo-6", the second test launch of a rocket Saturn-V. During launch one of the five engines of the second stage began to run rough. Intelligent Automatic noticed this ... but the other turned off the engine, because the wires to the motors were mixed. Fortunately, the second stage and three engines was able to pull out the third step of the ship in orbit. The program of the flight completely fails, but after this incident changed the length of the cables, they are now physically impossible to confuse. Well, this accident happened at an unmanned flight conditions for the accident eliminated, and it was not necessary to cancel the mission to the moon in the first minutes of flight.
Learning by accident h4> Surprisingly cognitive accident happened during the test suit for the "Apollo" in the chamber. In the context of an almost complete vacuum at the test engineer Jim Leblanc refused to mount the hose and the pressure in the suit beginning to fall sharply:
It all ended well - in the next cell to the reduced pressure were people ready to help, are rapidly removed from the chamber Leblanc. But because of this accident, we know that a person with a sharp depressurization time to feel the boil in the language of saliva before losing consciousness. We also know that the short-term loss of containment is not dangerous to humans - Jim LeBlanc lived until at least 2008, and maybe still alive today.
Nothing complicated h4> Actually, perhaps it is not very funny. But sometimes corny dropping satellites. In 2003, the production of meteorological satellite NOAA 19 one technician unscrewed 24 bolts securing the satellite platform, this action is not recorded in the log, and other techniques without checking fixtures, began to turn it into a horizontal position. The result was somewhat predictable:
The end of history has a good - despite the damage at $ 135 million satellite and repaired successfully launched in 2009.
Epic Fail and wine h4> And finally, the most optimistic story. This has already been quietly forgotten, but the beginning of the career of the telescope "Hubble" was catastrophic. When the telescope is set to work in space in 1990, it revealed that he suffers from a serious spherical aberration:
Instead of the normal range of the telescope there would be a point i>
The investigation revealed that the control of the primary mirror polishing was performed incorrectly assembled device. Two auxiliary null corrector showed the presence of spherical aberration, but the main null corrector, in which the lens mount installed extra washer, considered the most accurate, and trusted the wrong measurements. Image NASA flew through the floor. Developers telescope, who spent a decade at its creation, expressed condolences to the participants as a "national disaster" and "Hubble" put on a par with "Titanic" and "Hindenburg" in the comedy "The Naked pistolet2½: The Smell of Fear." But, fortunately, NASA did not give up. Already in 1993, for "Hubble" went the first expedition. The difficult conditions in the five long spacewalks on the telescope installed corrective mirror. Total for "Hubble" has been made five expeditions to seriously modernize the telescope and extend its lifetime. Even a little sad that the space shuttle is no longer flying, and this historic telescope can not serve on, and after a technical "death" will not be removed from the orbit, to put in a museum. But we will not be sad - the last servicing mission was in 2009, and "Hubble" long we will be able to delight chic photos:
On the tag «cosmic accident» accidents, disasters that have occurred or not.
