The Captiotian Aerospace Program (CapCosmos) has unveiled the base design for its upcoming exploration vehicle designed to carry 5 cosmonauts to and from the surface of Earth's moon as part of its Selena (Systemic Exploration of Lunar ENvironment Applications) Program. The vehicle features four main modules which will attach and separate and various points during the mission.
The Command Module is where the crew control the functions of the spacecraft and is the only part of the Selena vehicle to return to Earth. The Service Module contains propulsion, power, and auxiliary computer systems. The Command/Service Modules will launch with crew atop a Sigma 4 reusable rocket booster.
The Descent and Ascent Modules are collectively the lander. The Descent Module will power the entire landing sequence and serve as a platform upon which to attach science cargo. Upon departure from the moon's surface, the Ascent Module will detach from the Descent Module and fire 6 small engines to return to orbit and rendezvous with the Command/Service Module, which will return crew back to Earth. The Descent/Ascent Modules will launch atop a Sigma 4 Heavy reusable rocket booster.
