T+ 360 Days Engineering Log

The first 14 shaping burns were performed today without any issued with the EHEs. Several loose items rattled around inside of 1 of the maintenance modules which caused some damage to fixtures inside the module, but no hull penetration occurred.

It is expected that we will perform 10-16 shaping burns of 2 to 5 minutes each over the next 15 days until our EOI burn on T+375 Days in the mission.

All boards are green at this time.

Remaining mission timeline...

T+ 351 Days Engineering Log

No engineering issued have come up since the last log entry. Return cruise mode has been very uneventful. At T+ 350 days, MCC #6 was performed exactly as planned and now a complicated set of shaping burns will begin to reduce the burn time for our initial earth orbit insertion (EOI) burn.

Starting on T+ 360 a series of <5 minute burns will be performed. After each burn, the resulting approach orbit will be analyzed and the next burn will be calculated. The goal is to perform as...

MCC #5 was performed without any engineering issues. Calculations for MCC #6 have begun with the expectation that the Preliminary shaping burn for EOI will be broken up into a series of burns to slow down our approach speed to Earth while keeping our closest approach outside the atmosphere and also not delaying our arrival at the ISS.

On T+299 days into the mission, several minor pressure leaks were detected in unused Hydroponics modules on SSTV-01. It is suspected that we have flown...

T+ 293 Days Engineering Log

The last 3 weeks have been very busy ones. During the TEI burn, 3 of the EHEs showed higher temperatures than the rest and 4 showed lower temperatures than the rest, but all were within nominal operating temperatures. Only 4 will be used for MCC #5 and #6 plus any shaping burns prior to EOI.

Due to perturbations caused by the gravitational attraction of the larger moons of Jupiter following the TEI burn, MCC #5 will be slightly larger than originally anticipated. It will take place...

T+ 273 Days Engineering Log

After some orbital phasing it has been determined that a optimum departure date of T+274 days will get us back to LEO with the least amount of delta V for TEI. This means tomorrow we will say good bye to the Jupiter system and be on our way back to Earth.

During the phasing burns, we used several different combinations of EHEs and have completed a performance analysis on all of them. 3 of the EHEs appear to be more efficient than the rest whereas 5 of them appear to be less efficient...
