Mission report Hide contents Initially, the mission called for BACC boosters and an inertial upper stage to deliver the payload, however it was decided that the use of KD25k boosters would allow the orbiter to reach the phasing orbit without the need for an IUS Booster separation ET away Heading to GTO, Orbiter now has solar panels to provide power for longer missions Plotting phasing orbit, ap at stationary orbit altitude, period 2/3 of stationary First sat deployed Circularizing Second sat in orbit all 3 deployed With a successful deployment the crew prepared for re-entry. Simulations had shown that direct re-entry from stationary altitude was not recommended, but an entry from Periapsis altitude should be feasible, these simulations did not account for the instabilities caused by the additional fuel consumption such a maneuver would require, simulations run after launch showed that re-entry with less than 200m/s of OMS propellant would result in the orbiter going A/T at around 33 km. A last minute decision was made to perform two aerobraking passes from stationary altitude Shortly before the first pass the payload mount is jettisoned First pass, the forward RCS thruster blocks are noted to be particularly vulnerable, and should be replaced with more robust linear ports for future missions. Second pass Following this pass an opportunity For a KSC landing was spotted and a maneuver was performed to take advantage of it, unfortunately we can now revise our previous estimate for instability upward, to 225m/s remaining propellant Control regained KSC sighted, Due to the earlier tumble the orbiter is somewhat short on speed The OMS makes an heroic effort to gain some speed and altitude It is just barely enough Looks great, no problems on my part! 5 hours ago, sturmhauke said: I'd probably make a custom badge, honestly. Minmus is approximately the same difficulty as Mun, and Jool... isn't. (Or Sarnus, if you're using OPM). Maybe tooling around on Europa is similar to Minmus, but getting there is a completely different story. I think for overall missions parameters, the Jool series is a better fit. I'm wrapping up my interviews and should be receiving an offer soon. On the one hand, I'll be busy with my new job (unless something terrible happens), but on the other hand I won't be doing endless practice drills and should have some time for badges and new missions and stuff. Badge looks good! Sorry, I forgot to mention this earlier but I compiled some finished badges a while back. I'll send you the links. Well Minmus RSS could be Europe/Enceladus and Laythe RSS can be Titan. These badges are optional so i dont think the RSS folks would be set back compared to other people. You cant really add a minmus to RSS so saying that the blue surface is actually Enceladus is a good workaround i'd say Quote Link to comment Share on other sites More sharing options...
