After the failure of a rocket, Russia accelerates its next launch. NASA says it's okay.

(Dmitri Lovetsky / AP) The Russians are going fast. After the failure of one of their rockets last month, Roscosmos, the country's national space agency, announced the end of its absence. He knows what happened and how to fix it. Instead of delaying the next flight with astronauts – originally scheduled for December 20 – the launch is scheduled for December 3. Confident in his Russian counterpart, NASA has agreed. And Anne McClain, the next American astronaut in the flight rotation, says she is ready to tie up and leave. "I would have had Soyuz the next day," she told reporters on Friday. On October 11, a Russian Soyuz rocket suffered a breakdown in less than three minutes of flight when one of the side recalls failed to separate properly and struck the rocket. Roscosmos said the incident was caused by a damaged "deformed" sensor during the assembly of the rocket that had caused the problem of separating the booster. Since the accident, Russia has flown the unmanned Soyuz three times, restoring confidence in the system. In an interview Friday, Jim Bridenstine, a NASA administrator, said Roscosmos had been "very transparent. They shared with us all the data we need to be comfortable and confident to understand the problem and solve it. "[[[[The companies of the cosmos: explore the new race in space]He added that the flight had been moved to "allow our crew to board there as soon as possible" since the failure of the last mission. Scott Kelly, the former NASA astronaut who spent almost a year in space, said it was logical since two of the three crew members of the next flight were "recruits" who never went into space. Arriving early at the station "would give the crew time to make an efficient transfer," he said. "I could see why they would want to move this flight earlier if they could do it safely." Bridenstine said the crews had returned safely to NASA. After the collision between the booster and the rocket, the spacecraft immediately moved away from the rocket, carrying the astronauts – a Russian, an American NASA astronaut, Nick Hague, recently declared to the press that the first thing he had noticed was 7G, ​​seven times the force of gravity. The alarm rang, a light flashed and "once I saw the light, I knew we had an emergency with the reminder." Hague and his Russian counterpart, Alexey Ovchinin, were also immediately found. by the rescue teams, a much better result than a notorious abortion in 1975, when cosmonauts from the Soviet Union landed in a remote part of eastern Russia on the snow-covered side of a mountain and have almost fallen off a cliff. (They were found a day later.) But even when the abortions go well, they are still not supposed to happen. It was dangerously close to what is called in the jargon of the space industry a "bad day". Space travel carries inherent risks, but NASA and its partners are trying to reduce the risks. It seems like a "simple assembly error when they assembled the rocket," said Wayne Hale, former NASA Space Shuttle Program Manager. "It has nothing to do with basic design." The incident follows the discovery of a small mysterious hole drilled in a section. The hole is the subject of a separate investigation by Roscosmos. The Russians have launched the idea of ​​sabotage. The hole had been clogged awkwardly after its creation and, in the event of the patch 's failure, a small air leak from the station had set off alarms. The hole has since been repaired and is no longer considered a threat to the return of Soyuz as it is in a part of the space shuttle dropped in space. The two anomalies – the launch's failure and the Soyuz hole – are almost surely unrelated, according to industry experts. But this is a company that would like its current number of anomalies studied to be zero, not two. Bridenstine said the pair of problems "raised questions", but did not want to comment until the investigation was over. The incidents also recall that the Soyuz is the only way for man to get to the International Space Station. If the Soyuz were to remain on the ground for an extended period, NASA and its partners may have to temporarily abandon the station. "I would not put the crew at risk to keep it crewed," said Mike Suffredini, president and CEO of Axiom Space, which develops private space stations. Similarly, last month, a NASA safety advisory committee said that, wishing to meet deadlines, "there is potential for the workforce – strive to meet unrealistic dates." and to lobby for everything to happen in the right way – will subtly undermine healthy decision-making. The proposed launch dates are approaching. McClain said she was confident that Roscosmos had solved the problem by asking "the three important questions: what has happened? Why did this happen? And how to make sure that does not happen again? No one was going to give the green light until these three issues were resolved.
