Pathfinder 1
One full orbit (98.689 min), centred on the satellite's position now — dimmed behind it, solid ahead. The two ends do not join up: Earth turns beneath the orbit, so each pass runs about 24.7° west of the one before.
Judged on apogee — orbit is eccentric (e=0.01224, 173.11 km between apogee and perigee), so mean altitude would report roughly half of any apogee-only raise.
Apogee climbing: +160.6 km over the 81 days since the 2026-07-18 turn at 621.98 km (+1.98 km/day) — electric orbit-raising is proceeding, the mission's success signal.
Orbit is eccentric: apogee 782.53 km × perigee 609.42 km, 173.11 km apart (e=0.01224). Perigee has been held at 608.63 km (spread 4.89 km, -0.197 km/day) for 14 days — a controlled parameter, not drift: drag lowers a perigee, it does not pin one. Apogee is moving +1.64 km/day against perigee's -0.88 km/day over the last 29 days, so mean altitude (+0.38 km/day) averages the two and is not the figure to judge this phase on.
