"Editor's note" last night, SpaceX's "Falcon 9th" 139 seconds after the rocket exploded. "Falcon 9th" planned for the international space station carrying more than 4,000 pounds (about 1814 kg) of supplies, and at the beginning of the next few years the United States transporting astronauts to the international space station. Until then, Falcon 9th already once successfully performed a task and made three attempts to recover, though ended in failure, but in April in recovery experiments, the rocket is to smooth down to hundreds of meters in the air before they begin to fail, called "not far away from success."
This plan's main line was transporting supplies to the ISS, side quests is still recovery test (and is also the focus of media attention), but unfortunately during launch, there was a serious fault, the exploration ended in failure, primary reason is "the first section of the rocket liquid oxygen tank internal pressure anomaly" for reasons still under investigation.
In any case, the iron man Elon Musk of SpaceX and his was a big setback, but affect to what degree, Musk "on Mars retirement" scheme will come true? Known users, mechanical engineer @ old bi gives the answer.
Following is a body part, Lei feng's network does not change the intent of the edits were made.
United States space agency NASA is a COTS item (Note: the Commercial Orbital Transportation Services, the full name of "commercial orbital transportation service" is committed to working with business partners to develop space transportation business, NASA serves as the role of investors, technical consultants and customer, to purchase services from participating institutions, Space x is the winning one of the two institutions), The Falcon 9th carrying CRS-7 is part of the contract.
Talk about the influence of accident to contract both parties.
First is the party that is NASA's impact:
Direct impact on the international space station (ISS) loss of a cargo ship, including the conveyance of all of the cargo and the corresponding downlink capacity (according to 9ifly Forum cmj9808 netizens said, NASA has no economic losses in this failure, as COTS are paid after arrival, loss to be borne entirely by the SpaceX). The unprecedented pressure of COTS project because three contractors failed rounds in a row, including very reliable Russia Progress spacecraft are planted, though not more than a year Colombia accident could have disastrous, but the project itself is very tragic.
Accident on the station supplies will not be affected. Current conservative estimates material can adhere to in October, plus a few days later Russia spaceship Progress launched, can increase a month supply in August, Japan loading large cargo spacecraft HTV will launch this year, still has the ability to hit a six-month supply. While Orbital Science's engineers are cooperating and ULA Atlas-5 Cygnus spacecraft, is scheduled for launch in December between, now thinking ahead to October. (ULA CEO, Tory Bruno's voiceover is heard: ULA, America's ride to space ... ）
The station building is a limited number of combat. Docking Adapter, first lost, it would have been for APAS interface modification on the space station for the interface compatible with new standards; second, would be Japan's HTV.
Science experiments on the space station is a big blow. CRS-7 loads all of the loss of science, including many students. The sadness, yes there is a group of works in the last year, Antares (Note: COTS project to another company's ships, last year's implementation of the transportation plan 6 seconds into the explosion) damage in the accident, they've made on the backup machine in CRS-7, also blew up. Space station program manager Mike Suffredini said that their life is a lesson.
Has no effect on manned mission to space station. NASA manned space mission Deputy Chief William Gerstenmeier said the space station's six-person crew plans will continue as originally planned, even COTS all three freight forwarding contractor have failed again.
Followed by the b effect of SpaceX:
There is no doubt that was a heavy blow to SpaceX. Falcon 9th (hereinafter the "F9") had 18 times in a row since the first main task is successful, thought this time issue is not large, returns when a careless mistake at best hanging up, the result is completely disruptive incidents. COO of SpaceX in the media it was mentioned, F9 to be grounded for several months at least, specific length depends on the progress of the investigation on the cause of the accident and the cause itself, but not longer than a year.

Seen from the video capsule Dragon after the explosion is one piece, but only fell into the ocean and broke into pieces. Dragon 2.0 will have this kind of accident in the launch abort system (launch abort system) ability to escape from.
F9 is the only active SpaceX vehicles, this means that SpaceX space launch activities also temporarily stalled. SpaceX carried out six missions in the first half of this year, equal to the year 2014 the number of (long series only twice this year)--because of the accident, SpaceX has just embarked on a high-density launch on track, but had to pause.
All projects will go ahead, as long as the timely identification of reasons would not have shaken people's confidence. Golden Falcon 1th SpaceX a few years ago when a lot worse than it is now.
Cause of the accident can know only the Elon Musk of a Twitter, namely "abnormal secondary oxygen tank pressurization" (but under the rush, rigorous degree is debatable), COO at launch SpaceX also mentioned the possibility of secondary problems, but she had no more information than Elon Musk on Twitter for publication. Live video can provide evidence for this explanation, but specific reasons known only after the investigation is completed.
And landing tests between different is, this contract did not perform well, taxpayer-funded Boondoggle (adapters and supplies are paid for by NASA), do not take out a "withstand the inspection history" report is justified.
Falcon 9th is a promising rocket, hoped that after the setback before you can continue.
