Magellan Spacecraft with Inertial Upper Stage

The Magellan Spacecraft is also called the Venus Radar Mapper.

Tips on how to use it:
After deployment and before Inertial Upper Stage first stage ignition, open the solar panels then after satellite deployment, activate the Sun Sensors and don't deactivate them. 2 seconds after Inertial Upper Stage separation, activate AG8 to extend the nozzle and then after it is fully extended, activate the engine. Launch when Sergeaa is in front of Droo. Then the trajectory of it should have the periapsis not on Sergeaa's Orbit but close to it. Because you will make a correction burn once you pass the apoapsis again then 2 more burns to have a high inclination and a low periapsis of about 215-280 km. On orbital insertion, don't activate the orbit insertion motor until a few seconds. Still don't burn it on your journey until orbital insertion. Have an apoapsis of 7,715-7,780 km. After orbital insertion, detach the orbit insertion motor. It's ok to make some correction burns but follow the requirements of the orbit. When the periapsis is at the night side, map early by going to the day side. It should follow the direction it was moving before pitching 285° or 75° for the altimeter camera to face straight to the surface. When you're on the apoapsis, target Droo (Do not stop setting it as target) and Lock Target to pretend to take data from the spacecraft antenna to Droo by it's radars there. Use duoquan's Space Shuttle and my IUS Airborne Support Equipment to launch it to space and deploy.

Things you need to know:
They can be both saved as a subassembly but to detach the interstage, Detach the structural parts, interstage and inlet on the second stage. Do you know why can't you see the interstage? Because it was hidden in the inlet. Star Scanner Camera has the same view as observing camera 2. No burn nodes required for the Inertial Upper Stage first and second stage ignitions and Magellan Spacecraft Thrusters Burn 1. Also when you deploy the Magellan Spacecraft, It will reveal the orbit insertion motor. You can burn the orbit insertion motor only once. Also you can make a mission with it and post it on YouTube. The spacecraft was one of the few spacecraft to test aerobraking. The interstage is actually custom-made.
