What is the right space time???

I found these figures in some old NASA publicity books:

Sigma 7: 9 hours 13 minutes 11 seconds
Gemini 6: 25 hours 51 minutes 24 seconds
Apollo 7: 260 hours 9 minutes

which adds up to 295 hours 13 minutes.

And these figures in Kenneth Gatland's "Space Technology":

Sigma 7: 9 hours 13 minutes 11 seconds
Gemini 6: 25 hours 51 minutes 43 seconds
Apollo 7: 260 hours 9 minutes 3 seconds

which adds up to 295 hours 13 minutes 57 seconds.

Than have to check NASA history information, probably there the correct
info can be found...

Is that taking relativistic time dilation into consideration? That's got to
be
good for a -second or -two!

Also, I remember getting up very early to watch live TV coverage of the
Mercury
launches. By the time Schirra took his ride I was just 12y old and we just
moved
back to Fla. I wish I could claim to have seen the launch from Lakeland but
I
really don't remember.

At orbital speed (about 8 km/sec) time dilation doesn't even
amount to one second over 295 hours. If I've crunched the
number right, it's in the microsecond range.

If it's NASA, maybe they've mixed metric and SAE units ?

No, although they did give the orbital speed in furlongs per fortnight.

I made the time-dilation factor as about 0.999999999644 (square
root of 1 minus beta-squared), with Schirra spending about 1062000
seconds in space at orbital speed and beta equal to 8 km/sec over the
speed of light (close enough to 300,000 km/sec). Schirra would have
lost about 400 microseconds.

Oh Monty Python, I thought it was about time for another appearance........
Good one and well thought.

Before I can answer that, I'll have to determine whether or
not all four hundred of them float or sink in water. Making that
measurement for microseconds could take a little time.

From his point of view didn't *we* lose the ~400ms ?
