CCM Bonaventure 2

Cylero Crew Mission Bonaventure 2.

Space is hard.
A big, heavy, nuclear powered manned space craft for exploration of the Cylero system.

Start flight by placing craft in Droo orbit and select Cylero as target. Then select AG 1 to initiate Interplanetary Window Calculator. be patient, it can take a few minutes. follow the pop up instructions.

-Plenty of fuel if flown with care. Don't push it too hard. use a series of 3 minute burns at periapsis to raise your orbit incrementally to leave Droo SOI. it will take around 8 such burns. This "slingshot" method will save significant amount of fuel.

Use the same method to drop into an elliptical orbit of Cylero. An apoapsis of 4,000km and periapsis of 150 or so works well, and saves a lot of Delta V in the long run.

Now you can launch the two landers. Lander 1 is on the left Lander 2 on the right. Aerobrake to below 1000m/s to deploy hypersonic parachutes. at 1000m AGL cut the chutes by staging and go full power on landing engines, the ground comes up pretty fast, Feather power as needed, land as normal. You should have more than enough fuel to get back up to orbit for rendezvous and docking with Bonaventure.

When it's time to go home, save and exit flight, then resume from start screen this will reset the Window Calculation, Select and target Droo and hit AG1. at this point yo'll be getting pretty tight on fuel budget so you may want to cast off the landers to save weight. 3 burns will get you to escape velocity comfortably.

When returning to Drop, plan for a nice circular quarantine orbit just inside that of Brigo and send up crew recovery craft.

If you are skilled in space flight ,I think this craft will be a nice challenge. I tried to create a ship to simulate a realistic mission profile.
Hope you have fun with it.
