A new re-usable rocket prototype that will replace the current Sarnus V is under development in the VAB! The new rocket is designed to replace the Sarnus Rocket core that is used heavily in the space program!

Initially called the Sarnus VI, the project has now been determined to be such a radical shift from the Sarnus program that it deserves a new name, so the Neidon Rocket Project has several goals:

• Meet or exceed current Sarnus Vb launch system (50t to 200k orbit)
• Fully re-usable core rocket
• Core rocket capable of single-stage to orbit of payload
• Maintain compatibility with Sarnus Launch system upper stage payloads
• Maintain compatibility with side stages and launch assists (solid rockets) for Sarnus Launch System.
• Assess program for complete replacement of Nebula rocket system.

While the Nebula Heavy has taken some of those missions, operational complexity has made utilization a chore for Mission Control!

“That’s right – it’s finally time to retire the reliable Sarnus V!  But don’t worry – you’re all going to really like the replacement. Trust me!”
–Gene, answering questions at Mission Control

While the solid rocket boosters on the side of the Sarnus V (which is what makes it a Sarnus Va) are partially reusable, the center core (and most expensive component) of the Sarnus launch system is entirely lost.

A “would be nice” goal is to allow payload returns from orbit, something KSEA hasn’t been able to achieve since the Heavy Shuttles were retired.

“Maybe it’s satellite we need to bring back for repairs, or an interesting rock that won’t fit in any of our standard “rock collection” bags!  Either way we’re gonna need some kind of cargo bay to protect whatever during reentry!”
-Gillian

Construction on the prototype should be complete in 30 days!
