Mood is good this morning; ahead are the “Delta” mode tests. Relations within the crew are good, but with the ground they’re getting more complicated. Apparently it’s hard on Earth to put yourself in the crew’s place and feel our problems. Tomorrow I have to repair the sextant; I need to be calmer — I grumbled on the comm today. Now to bed. Tomorrow is a hard day. Today we disconnected the telemetry transmitters — it was difficult to reach them through the cables, and their connectors have locking mechanisms; I cut up all my hands.
