CONTRACT RELEASE: C07-060

NASA SELECTS PRIME CONTRACTOR FOR ARES I ROCKET AVIONICS

WASHINGTON - NASA has selected The Boeing Company of Huntsville, Ala.,
as the prime contractor to produce, deliver and install avionics
systems for the Ares I rocket that will launch the Orion crew
exploration vehicle into orbit. The selection is the final major
contract award for Ares I. The award resulted from a full and open
competition.

The Ares I launch vehicle is a key component of the Constellation
Program, which will send humans to the moon by 2020 to set up a lunar
outpost. Boeing will support the NASA design team leading the
development of the Ares I avionics components. The company also will
develop and acquire avionics hardware for the rocket and assemble,
inspect and integrate the avionics system components on the upper
stage. Components will be manufactured by the prime contractor’s
suppliers across the country. Final integration and checkout will
take place at NASA’s Michoud Assembly Facility in Louisiana.

The avionics are the “brains” of the Ares I and will provide guidance,
navigation and control for the rocket until it reaches orbit. The
avionics system is responsible for managing vehicle health and
reporting it to flight controllers based on a sequence of timed
events, such as engine shutdown and first stage separation.

The instrument unit that contains the bulk of the avionics will be
situated between the two-stage Ares I rocket and the adapter that
joins Ares I to the Orion spacecraft. The system consists of onboard
computers, flight controls, communications equipment and other
instruments and software for monitoring and adjusting the rocket’s
speed and position during flight.

Boeing will provide one instrument unit avionics ground test article,
three flight test units and six production flight units to support
integrated flight tests and missions through 2016. The contract type
is cost-plus-award-fee and the period of performance is Dec. 17,
2007, through Dec. 16, 2016. The estimated value for support to the
NASA-led design team and production of test and flight units is
$265,489,783. Additional tasks not included in the initial scope of
the contract may be acquired up to a maximum value of $420 million.
Additional flight units may be obtained at an estimated cost of
$114,045,292 for as many as 12 additional units. The total estimated
contract value is $799,535,079.

The Ares I first stage will be a five-segment solid rocket booster.
The upper, second stage of the rocket will consist of a J-2X
liquid-oxygen, liquid-hydrogen main engine, a new upper stage fuel
tank, and the instrument unit avionics.

NASA’s Marshall Space Flight Center in Huntsville, Ala., manages the
Ares Project for NASA’s Constellation Program, based at NASA’s
Johnson Space Center in Houston.

Uhmm…

Niente… avevo sbagliato io nell’altra news… il contratto era solo per il primo stadio e non per tutto il vettore… ho specificato meglio la precedente notizia…
