this would significantly help us with space travel. we can build ships with comfort because we don't need to fall back through the atmosphere. ships could be bigger. and able to make longer journeys in space. I understand money. but it would save money in the long run

I understand why. but why can we not go into the atmosphere at a slower speed. even with the space shuttle missions we still required a heat shield. why could we not just fly down slowly to avoid the risk with falling into the atmosphere. like a slow controlled glide/flight back down to earth. wouldn't it be safer.
