Inmarsat—Happy Kiwis Will Be Recipients Of Broadband

Inmarsat has announced that Telecom has been awarded the contract to establish and manage one of Inmarsat’s Pacific Ocean Region (POR) satellite access stations (SAS) for Global Xpress (GX).

The contract for this POR GX SAS marks an important milestone in the development and deployment of Inmarsat’s market-changing GX network, which will deliver the world’s first global Ka-band network, providing mobile users with true broadband speeds of up to 50Mbps.

Telecom will develop its Warkworth Satellite Earth Station, located near Auckland on New Zealand’s North Island, to host Inmarsat and its GX satellite antenna. Warkworth will act as a co-primary GX SAS for the POR, alongside Inmarsat’s own Land Earth Station and Teleport based in Auckland. Both will act as gateways between the broadband traffic routed via the POR satellite and terrestrial fixed networks.

Nick Clarke, Telecom’s GM Wholesale and International, said, “The scale of this project reinforces that New Zealand can meet demand for security of international bandwidth supply at competitive prices. In choosing a location for a satellite Earth station it needs to be cost-effective and have reliable connectivity to the rest of the world. Given the scale, we had to prove our capability at our Satellite Earth Station as well as our National Transport Service, which will backhaul the satellite data when it hits Earth and carry it internationally on the Southern Cross Cable.”

“The GX development program is on time and on budget,” said Leo Mondale, Managing Director, Growth Management & Support (GMS), Inmarsat. “The sites for all six GX satellite access stations have now been selected and operational readiness is well advanced on the stations supporting our first Inmarsat-5 satellite serving the Indian Ocean Region, which we expect to launch around the turn of the year.”

The full Inmarsat-5 constellation is on course to be deployed by the end of 2014, providing a single global broadband service which can be accessed by users on land, at sea and in the air. The satellites are currently under construction or testing at Boeing Space and Intelligence Systems’ (S&IS) El Segundo facility in California. 

Three Boeing 702HP satellites will provide new Ka-band high-data-rate mobile communications services.

Continuing a relationship spanning three decades, Inmarsat, the leading provider of global mobile satellite communications services, returned to Boeing in August 2010 to order three 702HP spacecraft to provide its new Ka-band global and high-capacity satellite services.

The new satellites will join Inmarsat’s fleet of 10 geostationary satellites that provide a wide range of voice and data services through an established global network of distributors and service providers.

Each Inmarsat-5 satellite will carry 89 Ka-band beams that will operate in geosynchronous orbit with flexible global coverage. The satellites are designed to generate approximately 15 kilowatts of power at the start of service and approximately 13.8 kilowatts at the end of their 15-year design life. To generate such high power, each spacecraft’s two solar wings employ five panels each of ultra triple-junction gallium arsenide solar cells. The Boeing 702HP carries the xenon ion propulsion system (XIPS) for all on-orbit maneuvering. When operational, the Inmarsat-5 satellites will provide Inmarsat with a comprehensive range of global mobile satellite services, including mobile broadband communications for deep-sea vessels, in-flight connectivity for airline passengers and streaming high-resolution video, voice and data.

Northrop Grumman + NeXolve—Templates Completed

NASA’s James Webb Space Telescope is dominated visually by the tennis-court sized sunshield, which separates the observatory into a warm sun-facing side and a cold anti-sun side.


Technicians at Northrop Grumman’s Space Park facilities in Redondo Beach, California, are conducting tests to ensure the Webb Telescope’s sunshield membrane layers meet flight performance requirements.

Each of the five sunshield layers helps to protect the telescope optics—or mirrors—from the sun’s heat. Northrop Grumman Corporation  and teammate NeXolve Corporation, a subsidiary of ManTech International Corporation, based in Huntsville, Alabama, completed the manufacturing of all template layers for the Webb Telescope sunshield.

The James Webb Space Telescope will be pointed so that the Sun, Earth and Moon are always on one side, and the sunshield will act like a parasol, keeping the optics and science instruments cool by keeping them in the shade and protecting them from the heat of the sun and warm spacecraft electronics. The sunshield will allow the telescope to cool down to a temperature below 50 Kelvin (equal to -370 degree F, or -223 degree C) by passively radiating its heat into space.

The template layers are the last step before manufacturing the final flight sunshield layers. After successful completion of a manufacturing readiness review, the team is now ready to produce the final flight layers. Northrop Grumman is under contract to NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for the design and development of the Webb Telescope’s optics, sunshield and spacecraft. NeXolve is subcontractor to Northrop Grumman to manufacture the one-of-a-kind sunshield membranes.

The sunshield template layers have the same design and manufacturing processes as the final flight layers. Each layer has been individually shape-tested to verify that they were built to requirements. As all five template layers are being subsequently tested at Northrop Grumman’s Space Park facilities to ensure the membranes meet flight performance requirements, NeXolve is beginning manufacturing of the final flight layers. Technicians at Northrop Grumman are also practicing folding and unfolding the five layers by hand on a test bed.

The Webb Telescope will primarily observe infrared light from faint and very distant objects. In order to detect infrared light, the optics have to be cold; thus, the sunshield passively cools the telescope to a temperature of -375 degrees F, preventing the observatory’s own heat from “blinding” its infrared sensing instruments. The sunshield membrane layers, each as thin as a human hair, are made of Kapton®, a tough, high-performance plastic coated with a reflective metal. On-orbit, the observatory will be pointed so that the sun, Earth and moon are always on one side, with the sunshield acting as an umbrella to shade the telescope mirrors and instruments from the warmer spacecraft electronics and the sun.

NASA—Deep Impact's Superb Service Comes To A Close

After almost nine years in space that included an unprecedented July 4th impact and subsequent flyby of a comet, an additional comet flyby, and the return of approximately 500,000 images of celestial objects, NASA’s Deep Impact mission has ended.


Artistic rendition of NASA’s Deep Impact spacecraft.

The project team at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, has reluctantly pronounced the mission at an end after being unable to communicate with the spacecraft for over a month. The last communication with the probe was August 8th. Deep Impact was history’s most traveled comet research mission, going about 4.7 billion miles (7.58 billion kilometers).

“Deep Impact has been a fantastic, long-lasting spacecraft that has produced far more data than we had planned,” said Mike A’Hearn, the Deep Impact principal investigator at the University of Maryland in College Park. “It has revolutionized our understanding of comets and their activity.”

Deep Impact successfully completed its original bold mission of six months in 2005 to investigate both the surface and interior composition of a comet, and a subsequent extended mission of another comet flyby and observations of planets around other stars that lasted from July 2007 to December 2010. Since then, the spacecraft has been continually used as a space-borne planetary observatory to capture images and other scientific data on several targets of opportunity with its telescopes and instrumentation.

Launched in January 2005, the spacecraft first traveled about 268 million miles (431 million kilometers) to the vicinity of comet Tempel 1. On July 3, 2005, the spacecraft deployed an impactor into the path of comet to essentially be run over by its nucleus on July 4. This caused material from below the comet’s surface to be blasted out into space where it could be examined by the telescopes and instrumentation of the flyby spacecraft. Sixteen days after that comet encounter, the Deep Impact team placed the spacecraft on a trajectory to fly back past Earth in late December 2007 to put it on course to encounter another comet, Hartley 2 in November 2010.

“Six months after launch, this spacecraft had already completed its planned mission to study comet Tempel 1,” said Tim Larson, project manager of Deep Impact at JPL. “But the science team kept finding interesting things to do, and through the ingenuity of our mission team and navigators and support of NASA’s Discovery Program, this spacecraft kept it up for more than eight years, producing amazing results all along the way.”

The spacecraft’s extended mission culminated in the successful flyby of comet Hartley 2 on November 4, 2010. Along the way, it also observed six different stars to confirm the motion of planets orbiting them, and took images and data of the Earth, the Moon and Mars. These data helped to confirm the existence of water on the Moon, and attempted to confirm the methane signature in the atmosphere of Mars. One sequence of images is a breathtaking view of the Moon transiting across the face of Earth.

In January 2012, Deep Impact performed imaging and accessed the composition of distant comet C/2009 P1 (Garradd). It took images of comet ISON this year and collected early images of comet ISON in June.

After losing contact with the spacecraft last month, mission controllers spent several weeks trying to uplink commands to reactivate its onboard systems. Although the exact cause of the loss is not known, analysis has uncovered a potential problem with computer time tagging that could have led to loss of control for Deep Impact’s orientation. That would then affect the positioning of its radio antennas, making communication difficult, as well as its solar arrays, which would in turn prevent the spacecraft from getting power and allow cold temperatures to ruin onboard equipment, essentially freezing its battery and propulsion systems.

“Despite this unexpected final curtain call, Deep Impact already achieved much more than ever was envisioned,” said Lindley Johnson, the Discovery Program Executive at NASA Headquarters, and the Program Executive for the mission since a year before it launched. “Deep Impact has completely overturned what we thought we knew about comets and also provided a treasure trove of additional planetary science that will be the source data of research for years to come.”

The mission is part of the Discovery Program managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama. JPL manages the Deep Impact mission for NASA’s Science Mission Directorate in Washington. Ball Aerospace & Technologies Corp. of Boulder, Colorado, built the spacecraft.
