Whenever I watch a space shuttle launch, I notice that the NASA commentators use the phrase, “on orbit” when the shuttle has made it to space. However, most news outlets use, “in orbit” to describe the shuttle’s location.

Which is correct?

You know, I noticed that terminology starting up some time ago … maybe 5-10 years. I don’t like “on orbit.” I agree that an astronaut is “in orbit.” Funny thing is how this migrated to other areas as well. I hear weather people say things like “12 inches of rain on the year” and sportscasters say “150 yards on the half.” Strange how the language can morph like, sometimes for no apparent good reason (like in this case).

Jeeeez … another math test. I gotta figure out how to register here.

Thanks for pointing this out, BC12D. I’d missed this. Wonder if NASA has some particular technical reason to say it this way?
