NASA and the National Oceanic and Atmospheric Administration (NOAA) have awarded a $423 million contract to Hughes Space and Communications, El Segundo, CA, for the manufacture, launch and delivery on-orbit of up to four weather-monitoring Geostationary Operational Environmental Satellites (GOES).

The procurement of the GOES-N through -Q spacecraft marks the

extension of this multi-satellite program designed to provide

continuous monitoring of the Earth's weather systems and the

related space environment. The new spacecraft will be used to

continue and enhance the functions of the current GOES I-M series

of spacecraft.

GOES spacecraft are a mainstay of modern weather forecasting,

providing meteorologists and hydrologists with visible and

infrared images of weather systems, and precise atmospheric

soundings. They orbit above the equator at a height of 22,238

miles, stationed at 75 degrees west longitude and 135 degrees west

longitude to provide broad views of the Atlantic and Pacific

oceans where storms can be monitored while first forming.

The basic contract value of $423.1 million provides for two

spacecraft, GOES-N and -O, at a fixed total price. There are

separate, fixed-price options for two additional spacecraft, GOES-

P and -Q, priced at $190.9 million and $185 million, respectively.

Along with these options, there are additional, separately

priced potential contract costs. They include Government-directed

task assignments; additional integration and test support;

changes to Government-furnished equipment deliveries; program-

related launch vehicle changes; directed launch delays (due

primarily to on-orbit satellites lasting longer than expected) and

related spacecraft ground storage; and post-storage testing.

The GOES program is a partnership between NOAA and NASA's

Goddard Space Flight Center, Greenbelt, MD. NOAA is responsible

for program management and budget, determining the technical

requirements for the spacecraft, operating the spacecraft in orbit

and disseminating the resulting data. The NASA Goddard GOES

project office is responsible for the acquisition of the

spacecraft and oversight of the contract, and will support NOAA

during the post-launch operations phase.

The first spacecraft purchased under this contract will be

ready for launch in October 2001. GOES N-Q will carry an Imager

and a Sounder to provide regular measurements of Earth's

atmosphere, cloud cover and land surfaces. Two of them also will

carry a Solar X-ray Imager and Space Environment Monitor instruments.
