Tag: TGALS

Getting to space has almost always been a multi-stage process. Those stages typically took the form of different stages of chemical rockets, but it doesn’t have to be that way. Plenty of alternative options have been proposed, and one that NASA has been working on for almost a decade is getting closer to commercialization. The project, known as the Towed-Glider Air Launch System (TGALS), uses three very different stages – a business jet, and glider, and two separate rockets – sort of. But its main advantage means that any airport large enough to host a business jet could also become a spaceport.
