On October 2, Lockheed Martin Commercial Launch Services and United Launch Alliance (ULSA) launched an Atlas V rocket that carried the Morelos-3 satellite to orbit for Mexico’s Ministry of Communications and Transportation (Secretaría de Comunicaciones y Transportes de México).
The mission, procured for Mexico by Lockheed Martin Commercial Launch Services, launched at 6:28 a.m. EDT from Space Launch Complex-41 and was the 100th successful mission for United Launch Alliance.
“Congratulations to Lockheed Martin Commercial Launch Services and Mexico’s Ministry of Communications and Transportation on today’s successful delivery of the Morelos-3 satellite into orbit, providing advanced telecommunications throughout Mexico.” said Jim Sponnick, ULA vice president, Atlas and Delta Programs. “Today was an especially proud day for our team as we launched our 100th, successful, one-at-a-time mission since the formation of ULA in 2006. Congratulations to the entire team, including our many mission partners on this unprecedented achievement.”
The Morelos-3 launch was accelerated to an earlier position on the Atlas launch manifest, thanks to an agreement with the United States Air Force. The agreement allowed the MEXSAT customer to launch atop an Atlas V rocket using a launch slot that was previously manifested for a Global Positioning System satellite.
This change demonstrates ULA’s ability to meet the needs of commercial customers and the U.S. Air Force’s willingness to accommodate the real-time and crucial needs of other satellite programs.
This mission was launched aboard an Atlas V 421 configuration vehicle, which includes a 4 meter diameter payload fairing and two Aerojet Rocketdyne solid rocket motors attached to the Atlas booster.
The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine and the Centaur upper stage was powered by the Aerojet Rocketdyne RL10C-1 engine. This was the 57th Atlas V launch since the vehicle’s inaugural mission in 2002 and the fifth in the 421 configuration.
Boeing is responsible for the design, development and delivery of this integrated system, which is comprised of a fixed service satellite and two Boeing geomobile satellites, two ground stations in Mexico for network and satellite control, and prototype user terminals. The first Boeing-built satellite for the MEXSAT system launched in May 2015, but was lost due to a launch vehicle failure.
“This latest milestone represents Boeing’s fourth generation of satellites for Mexico and underscores how our satellites’ capabilities improve daily and emergency communications,” said Mark Spiwak, president, Boeing Satellite Systems International.
Morelos-3 is part of the MEXSAT constellation of satellites, which provide secure communications for Mexico’s national security needs and communications to rural zones to complement other, existing networks.
The MEXSAT program is an end-to-end satellite communications system that provides 3G+ communications services to mobile terminals across multiple platforms. These services include education and health programs, voice, data, video and the Internet. After being on orbit for 10 months and following antennas extensions as well as completing required trial runs, the satellite will start normal operations.
With more than a century of combined heritage, United Launch Alliance is the nation’s most experienced and reliable launch service provider. ULA has successfully delivered 100 satellites to orbit that provide critical capabilities for troops in the field, aid meteorologists in tracking severe weather, enable personal device-based GPS navigation and unlock the mysteries of our solar system.
The Morelos-3 was delivered to a geo-synchronous transfer orbit and is the second of two communications satellites that comprise the MEXSAT communications satellite system. Mexsat is a constellation of satellites owned by Mexico’s Secretaría de Comunicaciones y Transportes (Ministry of Communications and Transportation) and operated by Telecomunicaciones de México (Telecommunications of Mexico) that delivers advanced telecommunications throughout Mexico.
Morelos-3 is a 702HP geomobile satellite built by The Boeing Company. The 702HP satellite will supply 14 kilowatts of power through five panel solar array wings that use high-efficiency, ultra triple-junction, gallium arsenide solar cells. The satellite will also carry a 22 meter L-band reflector that enables connectivity to handheld terminals, complemented by a 2 meter Ku-band antenna. The life expectancy for Morelos-3 is 15 years.
Lockheed Martin Commercial Launch Services, is a wholly owned subsidiary of the Lockheed Martin Corporation and markets the Atlas V to commercial satellite customers worldwide. The company also offers Athena launch services for small satellites and multi-payload RideShare missions. The company is responsible for contracts, marketing, sales and mission management for commercial and international government Atlas V missions and all Athena missions.
Orbital ATK’s Crucial Contributions
Orbital ATK, Inc. provided critical launch vehicle and satellite payload hardware for the Lockheed Martin Commercial Launch Services launch of Mexico’s Morelos-3 satellite aboard an Atlas V.
Morelos-3 is the second satellite within the MEXSAT communications satellite system. MEXSAT is a constellation of satellites owned by Secretaría de Comunicaciones y Transportes, a government agency of Mexico, and operated by Telecomunicaciones de México, which delivers advanced mobile and fixed satellite telecommunications throughout Mexico.
Orbital ATK’s contributions to the Atlas V and Morelos-3 satellite include cutting-edge technologies from across the company. Contributions include a large composite faring, retro motors and propellant tanks for the rocket, and thermal and structural components on the satellite.
For the Atlas V rocket, Orbital ATK produced the 10-foot diameter composite heat shield, which provides higher performance with lower weight, and essential protection for the first stage of the launch vehicle from engine exhaust temperatures in excess of 4,000 degrees Fahrenheit. The assembly was fabricated using advanced fiber placement manufacturing techniques at Orbital ATK’s Iuka, Mississippi facility. This is the 57th Atlas V launch using Orbital ATK-built composite structures.
This launch also marked the 22nd successful flight of Orbital ATK produced retro motors. Eight of these solid motors supported separation of the spent first stage. The Atlas V retrorocket is built at Orbital ATK’s Missile Defense and Controls facility in Elkton, Maryland.
For the Morelos-3 satellite, Orbital ATK provided the structures for the booms and the 22-meter payload antenna that make up the precision stable backing structure for the Harris deployable antenna. Orbital ATK’s Space Components Division facility in Magna, Utah, manufactured these components for the spacecraft.
The division also supplied propellant tanks for the Atlas V rocket. Orbital ATK has provided similar structural components for the spacecraft industry for more than 35 years from sites in California and Utah. The Orbital ATK Beltsville, Maryland, facility manufactured the Loop Heat Pipes and payload heat pipes which are an integral part of the satellite’s thermal control system. Orbital ATK has delivered more than 50,000 heat pipes to the space industry with perfect, on-orbit mission success.
“With every launch I am reminded that the products we build are extremely important to our customers,” said Scott Lehr, President of Orbital ATK’s Flight Systems Group. “We are pleased to be a part of this important mission to help increase the telecommunications capability of the Government of Mexico.”
