RHEA

Rhea is Saturn Aerospace’s most powerful vehicle. Weighing over 1200 tonnes, it is a super heavy launch vehicle designed for the most demanding missions.

Rhea has undergone many design changes over the years. We are currently developing Block 4, known as RHE4. This fourth iteration is our most powerful and advanced design yet, delivering the highest performance and the most technologically capable launches in Saturn’s fleet.

Rhea plays a crucial role in Saturn Aerospace’s operations, lifting payloads that are simply too large for any of our other vehicles.

Key statistics for Rhea:

The first stage is powered by 33 Anthe engines, producing over 1600 tonnes of thrust at liftoff.

Rhea can carry more than 100 tonnes into Low Earth Orbit while being fully reusable.

The first stage returns to the launch site after launch, where it is caught by the launch tower chopsticks.

Where it all starts, the launch. Iapetus ignites all 33 Anthe engines before releasing from the pad propelling it towards space. Watching Rhea launch is an unforgetable moment.

LAUNCH

RECOVER

After Hotstaging Iapetus reignites the previously shutdown 10 outer Anthe engines and begins in boost back burn, pointing back towards the launchsite to cancel out velocity. After that it enters a coast phase when it reenters earths atmosphere. The external forces on Iapetus cannot be understated during this phase. Iapetus then transitions into landing burn where the 13 Inner anthe engines ignite. Slowly manevouring over to the chopsticks which close on the vehicle marking a succesful catch.

After landing Iapetus is safed. The remaining tank propellant and pressure are vented and then within an hour Iapetus is laid back on the pad where we can just mount another Rhea to it, refuel it, and launch it again.
