Unscramble the Blue Letters

Here's the problem. Mars is a long way away, a tnuoshad times farther away from us than our own moon. The Moon is 250,000 miles away and it took Apollo astronauts three days to get there. Mars is 250 million meils away and it will take us eight months to get there — 240 days. And that's only if we launch on a very specific day, at a very specific time, once every two years, when Mars and the Earth are aligned just so, so the distance that the rocket would have to tevral will be the soetsrht. 240 days is a long time to spend trapped with your cleeoluags in a tin can.

Original Text

Here's the problem. Mars is a long way away, a thousand times farther away from us than our own moon. The Moon is 250,000 miles away and it took Apollo astronauts three days to get there. Mars is 250 million miles away and it will take us eight months to get there — 240 days. And that's only if we launch on a very specific day, at a very specific time, once every two years, when Mars and the Earth are aligned just so, so the distance that the rocket would have to travel will be the shortest. 240 days is a long time to spend trapped with your colleagues in a tin can.
