Lockheed Martin Space Systems of Denver on Jan. 7 said it had delivered the core structure for the first in the National Oceanic and Atmospheric Administrationโ€™s series of next-generation geostationary weather satellites to the companyโ€™s Mississippi Space and Technology Center for propulsion system integration.

The rigid external structure for the first Geostationary Operational Environmental Satellite (GOES)-R series spacecraft, which will enclose the satelliteโ€™s propulsion system and support its instruments and other payloads, was designed by Lockheed Martin and built by ATK Aerospaceโ€™s Space and Components Division in San Diego.

A Lockheed team at Stennis will spend the next 11 months integrating GOES-Rโ€™s fuel tanks, lines, thermal controls and other systems within the core structure, the company said. The satellite is scheduled to launch in 2015.

โ€œThe core structure is half of a bus,โ€ Lockheed spokesman Gary Napier said in a Jan. 8 email. โ€œItโ€™s the inner structure that houses the propulsion system. Another structure that we call the U structure is the other half. When the two are put together in Denver next year, then weโ€™ll have a full bus.โ€

GOES-R is based on Lockheedโ€™s A2100 satellite series.

In a separate press release, Lockheed said Jan. 8 a key space weather instrument that its Palo Alto, Calif.-based Advanced Technology Center is building for GOES-R is on track to be delivered to Denver in October where it will be integrated with the satellite.

The instrument, the Solar Ultraviolet Imager, or SUVI, completed a pre-environmental review in November, clearing the way for it to begin a series of environmental tests expected to wrap up by May, Lockheed Martin spokesman Buddy Nelson said Jan. 8.

The instrument will be stored at Lockheedโ€™s Palo Alto facility until it ships out for Denver later this year, Nelson said.
