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...

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...

After undocking from the Europa L2 station and transposing the XR5 we are bringing home to the forward docking port, SSTV-01 performed a minimum energy departure from Europa using 4 EHEs. We are now phasing our orbit around Jupiter for a high impulse TEI burn within the next 13 days. Initial calculations show that our most efficient burn can take place on day 11 but we will refine our calculations to determine if phasing burns while in Jupiter orbit can improve on that.

All boards...

T minus 1 day until we undock from the newly completed Europa L2 Station and begin our trip back to the Lunar Station. SSTV-01 is fully fueled and all provisions have been topped off. As the L2 station is able to produce all the food and life support required for its crew, we have shut down all unnecessary life support and hydroponics modules on SSTV-01. They will remain shut down until we have docked with the Lunar Station 134 days from now.

All the EHEs have been tested and are...

Europa L2 Station construction was officially completed today although there are a few odds-and-ends to finish up.

The 2 XR5s we brought along are now being used to bring up water melted from the icy surface of Europa. That water will be converted into LOX for the station and LH2 to fuel SSTV-01 for our trip home. As we barely used 25% of our total fuel load to get here, we could make the entire return trip back without refueling, but just in case our entire bank of EHEs fail on...
