June 5 Boeing Starliner capsule He went to the International Space Station and it was all a celebration. After several delays and failed launch attempts, it seemed that the difficulties were finally over. But in reality they have just begun. If the departure is delayed, the return is not far off, and the worst thing is that this means two astronauts. caught up with on the International Space Station (ISS), not knowing when they will be able to home.
Boeing insists they are not, in fact, trapped. In fact, they assure that in the event of an emergency that forces them to leave the ISS facilities, Starliner will be fully mission ready. journey back to Earth.
However, a number of issues have emerged in recent weeks that have forced them to be extremely cautious. First there were helium leaks, and now we are talking about shunting engine failures. In addition, the astronauts’ spacesuits also caused some problems. After several delays, they no longer even dare to name a return date.
Starliner’s problems returning home
Before Starliner’s final launch, it was discovered that its helium tanks had suffered a small fuel leak. Scientists did not attach any importance to this, since the ship withstood up to five such leaks without problems. As soon as we left for the ISS, the second was discovered, and then the third and fourth. The fifth was already seen with a capsule docked to the ISS.
This was a wake-up call for Boeing scientists. The limit has been reached. However, studies by technicians have shown that, in fact, if the valves were closed, there would be more than enough helium left for the return trip.
They could return, but it would be better to continue analyzing the Starliner’s condition. It was also ideal timing for the two crew members, the astronauts. Butch Wilmore and Suni Williamsdo spacewalk on the outskirts of the ISS.
The problem is that even the walk had to be postponed due to problems with the comfort of the spacesuit. After their decision, two walks are planned, one for today, June 24and also for him July 2. After this, they will no longer have to work at the site, but their return date now remains a mystery.
What do they need to do to get back?
Boeing technical experts say there is enough helium for return. However, during tests of 28 maneuvering engines carried out with the capsule docked to the ISS, Faults were found in 5 of them.
This will be a new headache that could further delay the return of the mission. Starliner was originally scheduled to return to Earth on June 18, but there is currently no date. This will be after July 2, but nothing further is known.
Despite this, Boeing maintains that Wilmore and Williams in a good mood and that they enjoy being on the International Space Station. It is clear that astronauts are made of different stuff. Either way, we hope they return home soon.
