If you thought that COVID-19 couldn’t possibly impact space travel, think again. The ongoing pandemic is having unexpected consequences for companies like SpaceX, who are worried about liquid oxygen shortages due to increased demand for medical oxygen. Massive amounts of liquid oxygen are used as the oxidizer for each rocket launch, of course, as well as in hospitals, which have giant tanks of liquid oxygen somewhere on site. Whether destined for space or for patient care, liquid oxygen comes from cryogenic separation plants, and SpaceX fears that they would have to delay or even cancel launches if manufacturers can’t keep up with demand and have to prioritize their healthcare customers. We’re actually not sure if this is a concern, though, since there are usually separate supply chains for medical and industrial gasses. Then again, we’d suspect a rocket engine might prefer to breathe ultra-pure LOX too.
Speaking of space, if you want to be an astronaut, perhaps the first skill you need to develop is patience. Not only might your ride not be ready to go when you are, but at least in the EU, you’ve got a long line of applicants in front of you. The European Space Agency announced this week that they’re working through a backlog of 23,000 applications for astronaut positions. About 20% of those will apparently be dropped in the pre-screening process, but the rest will (eventually) get an invitation to a full-day test at one of the ESA’s facilities. We imagine the attrition rate from there increases dramatically; either that or the ESA int ..
