If rockets are so enormous, why are the ships that the astronauts land in so small?
It's one of the first weird things that you notice about space travel. The massive size difference doesn't seem to add up. Until you realize why. That massive rocket? It's all just fuel—evidence of how much power it takes for even a relatively tiny craft like Apollo to leave Earth's gravity.
Wouldn't it be cool if you could actually see inside the rocket to see how fuel is there? Look no further than this video!
The answer is clear
A very creative YouTuber called Hazegrayart has taken the time to animate four rockets from NASA's past, present, and future... and show the immense fuel stores inside.
On the left is Saturn V, which sent Apollo astronauts to the Moon. Next is the Space Shuttle, which dominated NASA missions in the 1980s and 90s. Third is Space X's current powerhouse, the Heavy Falcon rocket. And last is the Space Launch System (SLS), the proposed rocket that will send NASA's Artemis astronauts back to the Moon in this next decade and beyond. The video shows the rockets journey from launch to orbit in real time, so it's a bit long, but it's worth it.
So what do you say? Are you ready to launch? 10, 9, 8, 7...
