WASHINGTON -- NASA has authorized a contract with a maximum value of

Bettendorf, Iowa, to supply aluminum lithium plates and metal ingots
for early development of the Ares I crew launch vehicles upper stage.
The firm fixed-price contract has a period of performance through

Ares I is an in-line, two-stage rocket that will transport to low
Earth orbit the Orion crew exploration vehicle containing up to six
astronauts. The first stage will consist of a single reusable solid
rocket booster similar to those used on the space shuttle, with an
additional fifth segment. The second, or upper, stage will consist of
a J-2X main engine fueled by liquid hydrogen and liquid oxygen
propellants.
