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.

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

Yes, but it's all relative.

Really?

Must be on me mudder's side...
