When you want to wish an astronaut "safe travels", what particular phrases are commonly used?

I'm looking for historical phrases as well as more modern.

Although I'm more interested in English phrases, answers for all languages are welcome, as long as you provide an English translation

  • $\begingroup$ I can say one fact about Russian cosmonauts. Most of them don't like to tell and hear about their "last" spaceflight ("последний" in Russian). Yes, it's some superstitious - don't call flight the "last" one or you can die. They prefer the word like "edge" flight ("крайний"). So it's preferable to not say something like "I wish you a success in your last flight". Actually, most Russian aircraft pilots have this custom too. I don't know is the custom widespread between non-Russian astronauts and pilots... $\endgroup$ – Heopps Jun 1 '20 at 14:16

"Have a good flight" works.

"Godspeed" is traditional in the US space program, not necessarily as a religious reference, but because Scott Carpenter said it to John Glenn.

Here's a sign from the training team at the STS-135 crew sendoff at Ellington Field. (July 4, 2011)
