I am happy to announce that VEX has successfully completed the last pericenter raising OCM (orbit correction manoeuvre) without problems.
The final orbit will be announced later, but we achieved a roughly 460-km pericenter height and an about 63000-km apocenter height, with a new orbit duration of roughly 22h and 24 minutes.
Some facts on the OCMs:
- Over the 15 OCMs, each thruster fired more than 8000 pulses and burned about 1.3 kilos of propellant (NTO and MMH) bringing the total consumption to around 5.2 kilos for the raising.
- No degradation or signs of tank depletion was seen.
- The spacecraft still seems to be in excellent shape.
Meanwhile, the entire team is busy working to to restart full science on this new orbit.
