With no time to waste, Mirphe and Tamre fly to White Mesa and board Crew Vehicle 4, already waiting at the launch pad!
“Seely is already getting Discovery ready to go, as soon as we’re up there we’re taking off!”
Crew Vehicle 4 blasts off on it’s Nebula Rocket!
Once the spacecraft reaches it’s 200k apogee, the Crew Vehicle detaches and uses it’s RCS thrusters to move clear of the first stage Nebula Rocket!
The Nebula Rocket uses it’s own RCS thrusters to invert itself, and fire it’s main engine, to perform a propulsive landing at KSC!
“We’re clear to rendevous to Spacedock!”
The Crew Vehicle arrives at Spacedock!
“Welcome to Spacedock CV4! Discovery is fueled up and ready to go!”
The Crew Vehicle docks! Mirphe and Tamre rush to help Seely get the lander out!
“Hey – why are all the doors open on CV1!?”
“They got stuck open! It shouldn’t have any impact on the return, just annoying!”
Mirphe, Seely, and Tamre board Discovery… and undock!
“RCS thrusters firing in reverse… moving clear of Spacedock! Let’s get the reactor powered up to maximum!”
Discovery turns from Spacedock as the entire spacecraft shudders from the engines and reactor powering up!
“Reactor showing 100%! We’re good to power up engines!”
“Good luck Discovery!”
Discovery’s three nuclear engines fire, and it slowly builds up speed!
4 minutes into the burn, alarms sound!
“Looks like the rear engine housing is giving us trouble again! It’s heating up from the engines and not transferring enough heat to the Radiators!”
“If we reduce thrust to 50 percent we should be fine… the burn will just take longer!”
With the overheating problem out of the way, Discovery completes it’s burn for Duna, and soars out of the system!
“Wow – we are moving fast! We should reach Duna in less than 70 days! Once we enter orbit and dock we’re not going to have much fuel left!”
“That’s the idea! The return to Kerbin from Duna using the correct launch window is much less demanding – we’ll be fine! Let’s get ready to enter Cryo-sleep!”
