The Black Hole1979

V.I.N.CENT:
[beep] 2130; day 547. Unscheduled course correction due at 2200. Pre-correction check: rotation axis plus three degrees. Nitrous oxide pressure: 4100 rising to 5,000. Quad jet C and D on preselect. Rotor ignition sequence beginning in 3-0. Thruster line reactors on standby.

Dan Holland:
V.I.N.CENT, notify me with 15 to go. Alex?

Durant:
Yes, Dan?

Dan Holland:
Have you determined a difference in ETAs with and without our correction?

Durant:
Working on it. You know, we shouldn't be needing a correction at this time. V.I.N.CENT, run a confirmation on the last inertial fix and check it with another celestial, please.

V.I.N.CENT:
[beep] I have. It is correct. But I think I've found the reason for our present variation. Mr. Pizer?

Lieutenant Charles Pizer:
Yes, V.I.N.CENT?

V.I.N.CENT:
[beep] Mr. Pizer, I think you should come up here.
