If you think COVID-19 is unlikely to affect space travel, please think again.The ongoing pandemic has unintended consequences for companies like SpaceX, who are Worried about increasing demand for medical oxygen leading to a shortage of liquid oxygenA large amount of liquid oxygen is used as the oxidant for each rocket launch. Of course, there are also hospitals, where there are huge liquid oxygen tanks somewhere on the scene. Whether it is used in space or for patient care, liquid oxygen comes from cryogenic separation plants, and SpaceX is concerned that if manufacturers cannot meet demand and must prioritize their healthcare customers, they will have to delay or even cancel the launch. However, we are actually not sure if this is a problem, because medical and industrial gases usually have separate supply chains. Again, we suspect that rocket engines may also prefer to inhale ultra-pure LOX.
Speaking of space, if you want to be an astronaut, perhaps the first skill you need to develop is patience. When you are ready, not only may your journey not be ready, but at least in the European Union, you have a long line of applicants. The European Space Agency announced this week, They are processing a backlog of 23,000 applications For astronaut positions. Obviously, about 20% of this will be dropped during the pre-screening process, but the rest will (eventually) receive an invitation to conduct a full-day test at one of the ESA facilities. We imagine the attrition rate from there will increase dramatically; either the European Space Agency intends to hire a large number of astronauts.
Back on Earth, Google did what it seemed to do a lot this week and killed one of its popular apps.this time The victim is the Android Auto mobile app, Although we have to admit that the whole thing is confusing. This application allows you to connect your phone to the infotainment system in a compatible new car, allowing you to access all applications without having to fiddle with your phone while driving. But Google also has an app that can provide the same experience directly on the phone, suitable for cars that don’t have a compatible display. As far as we know, apps on mobile phones are the only thing that disappears in Android 12. Will continue to support applications for in-vehicle displays. Encourage former users who only use mobile phone applications to migrate to the driving mode of Google Assistant. Or, you know, you can drive instead.
So your brand new graphics card is very hot, and you don’t know why. You open the cover of the card wittily and find out the reason-a foreign object that looks a little suspicious.This is what happened Antony ter Horst and his Nvidia RTX 3090 with a finger cot insideIt appears to have slipped from the fingers of an assembler, and it obviously interfered with the heat flow in the card. Anthony posted these photos on reddit, which of course found a lot of humor in the similarities between the finger cots and another latex object. As far as we are concerned, it reminds us of the stories of foreign objects found in some other common products- We always check a loaf of bread before using it for a reason.
Finally, in many ways, YouTube has become the new “broad wasteland” of useless content. But just like the previous TV, some gems will occasionally be found, especially for those of us who like to watch and learn.So when we stumbled upon Video titled “Smoky Lake’s hot water tap and blocking bypass” We have to check it just to find out the meaning of each word. It turns out that this is a wonderful video about pipeline construction methods. The “hot water tap” refers to a pipeline containing high-pressure diluted bitumen from the shale oil field near Smoky Lake in Alberta without interrupting the flow of the product. A “plug” is a device that can be screwed into a pipe to permanently seal the pipe, diverting the flow to a newly installed bypass. The whole process is very interesting, so we thought we would share. enjoy.
