Crew Exploration Vehicle CEV Low Earth Orbit, Moon, Mars

1
Crew Exploration Vehicle (CEV) Low Earth
Orbit, Moon, Mars Beyond
CEV proposal development schedule 2008 - The
first prototype CEV is to be launched with a
candidate launch vehicle. The
prototype is selected from the winner of the Demo
fly-off competition. 2008/3rd Quarter - NASA
selects the final design for the lunar
spacecraft. 2011 - First unmanned flight of CEV
in Earth orbit. 2014 - First manned flight of
CEV in Earth orbit. 2014 - First unmanned flight
of lunar spacecraft. 2015 - First manned flight
of lunar spacecraft. 2015 to 2020 - First moon
landing by astronauts in lunar spacecraft.

2008 Demonstration Concept

• Two contractor teams selected to compete for the
  CEV build.
• - Northrop Grumman/Boeing
• Lockheed Martin
• Demo eliminated to permit CEV to replace shuttle
  in 2010.
• Two vehicle Demo fly-off would have occurred by
  September 2008.
• One contractor to be selected in 2006.
• Demo concept would use a Space Shuttle derived
  or an expendable launch vehicle.
• Design selected will be what makes the most
  sense for a 21st century lunar craft.
  Reusability is not essential.

Lunar Missions Concept

• Configuration is used for long duration missions
  (up to 19 days) in lunar orbit.
• CEV lunar missions concept consists of two
  separate launches.
• Crew vehicle launches separately from the
  mission module and the propulsion stage.
• Two vehicles rendezvous in orbit to create a 70
  feet (21.34 meters) long vehicle weighing just
  under 88,200 lbs (40,000 kgs).
• Mission module has habitation space for the
  astronauts.

CEV Development

• NASA plans to have the winner of the fly-off
  competition design the CEV in a series of
  exploration spirals, or complete designs with
  spacecraft systems and subsystems

• Spiral One (CEV Earth Orbit Capability). By
  2014, Spiral 1 establishes the capability to test
  crew transportation elements in low Earth orbit
  in preparation for human missions to the Moon. As
  new elements are developed, they will be tested
  in space with the Spiral 1 CEV.
• Spiral Two (Extended Lunar Exploration). By 2015
  - 2020, Spiral 2 will put humans on the Moon for
  at least four days.
• Spiral Three (Long Duration Lunar Exploration).
  After 2020, Spiral 3 will allow routine
  long-duration human missions on the surface of
  the Moon to test technologies and operational
  techniques for sending humans to Mars and beyond.
  Missions in Spiral 3 will last up to several
  months, serving as an operational analog of
  short-stay Mars missions.
• Spiral Four (Crew Transportation System Mars
  Flyby). After 2020, Spiral 4 equipment will allow
  a Mars flyby mission using elements of the
  Human-Mars Crew Transportation System.
• Spiral Five (Human Mars Surface Campaign). After
  2020, Spiral 5 elements will send humans to Mars.
  
• NASA will revise the development schedule to
  replace the Space Shuttle with the CEV when the
  shuttle retires in 2010.

Lockheed Martin CEV Demo Concept

• Lockheed Martin associated with EADS SPACE
  Transportation, United Space Alliance, Honeywell,
  Orbital Sciences, Hamilton Sundstrand and Wyle
  Laboratories.
• Transported to low Earth orbit on an Atlas V
  expendable launch vehicle.
• Operations are under autonomous control.
• Reuseable lifting body design for high speed
  return to Earth.
• Parachutes and air bags allow to set down on land
  or water.

13
Crew Vehicle Concept

• Transported to low Earth orbit on a Space Shuttle
  derived or upgraded heavy-lift expendable launch
  vehicle.
• Titanium crew module holds four to six astronauts
  and their equipment.
• Rescue module is located in the front 22 feet
  (6.71 meters) of the crew module, and it can be
  separated at any time in an emergency.
• Diagnostic safety system to troubleshoot
  problems.
• Power generation for long-duration space travel.
• Interchangeable computer systems will increase
  adaptability between modules.
• Thermal Protection System includes a backed-up,
  carbon-carbon heat shield - foam insulation was
  not selected.
• Crew Vehicle is equipped with parachutes and
  airbags to set down on land or water. It is not
  designed to glide after re-entry like the Space
  Shuttle and land on a runway.
