Crew exploration vehicle

The next generation of space vehicles will feature capsules that return to Earth via parachute. This is in contrast to the glider reentry Space Shuttle design. Shown here is Lockheed-Marrins preliminary design, which features an aerodynamic Crew Exploration Vehicle, CEV, that permits some maneuverability during descent.

Currently, Yardney is in continuous production of secondary lithium-ion batteries, primary and secondary silver-zinc batteries and primary reserve silver-zinc batteries used on various Department of Defense applications. The primary battery applications include the Navy s Trident IID5 Fleet Ballistic Missile program, the Minuteman III ICBM, and primary power for the MK 21 re-entry vehicle. In 2012, the Trident II missile has achieved 143 successful test launches since 1989—a record unmatched by any other large ballistic missile or space launch vehicle. The most prominent Li-ion batteries made by Yardney have powered the Mars Explorer Rover missions (Spirit, Opportunity, and Curiosity), the USAF B-2 Bomber and Global Hawk aircraft, and the US Navy Advanced SEAL Delivery System (ASDS). One of the future applications for Yardney s Li-ion batteries is NASA s Orion Crew Exploration Vehicle (CEV). 

To illustrate how LADs will be required at nearly

Exploration Systems Architecture Study (Anonymous, 2005). Two heavy lift LOX/LH2 rockets would launch from Earth, one carrying the astronauts and crew exploration vehicle (CEV), and one carrying the Earth Departure Stage (EDS), Lunar Service Access Module (LSAM), LSAM ascent and descent stages, and equipment for the 6 month Lunar surface mission. Therefore, both systems carry onboard all the propellant required for the entire mission, which increases the size of the launch system dramatically.
