Design

The MPCV resembles its Apollo-era predecessors, but its technology and capability are more advanced. It is designed to support long-duration deep space missions of up to six months. The spacecraft's life support, propulsion, thermal protection and avionics systems are designed to be upgradeable as new technologies become available.

The MPCV spacecraft includes both crew and service modules, and a spacecraft adaptor.

The MPCV's crew module is larger than Apollo's and can support more crew members for short or long-duration spaceflight missions. The service module fuels and propels the spacecraft as well as storing oxygen and water for astronauts. The service module's structure is also being designed to provide locations to mount scientific experiments and cargo.

Crew Module

The crew module is the transportation capsule that provides a hospitable habitat for the crew, provides storage for consumables and research instruments, and serves as the docking port for crew transfers. The crew module is the only part of the MPCV that returns to Earth after each mission.

The crew module will have 316 cubic feet (8.9 m³) and capabilities of carrying four astronauts for 21 day flights itself which could be expanded through additional service modules. Its designers claim that the MPCV is designed to be 10 times safer during ascent and entry than the Space Shuttle
Space Shuttle
The Space Shuttle was a manned orbital rocket and spacecraft system operated by NASA on 135 missions from 1981 to 2011. The system combined rocket launch, orbital spacecraft, and re-entry spaceplane with modular add-ons...

.

Service Module

Like the Apollo service modules, the MPCV service module supports the crew module from launch through separation prior to reentry. It provides in-space propulsion capability for orbital transfer, attitude control, and high altitude ascent aborts. When mated with the crew module, it provides the water and oxygen needed for a habitable environment, generates and stores electrical power while on-orbit, and maintains the temperature of the vehicle's systems and components.

This module can also transport unpressurized cargo and scientific payloads.
