NASA’S Webb Telescope Passes Mission Design Review Milestone
Filed under: NASA, Syndicated Industry News, northrop grumman, space
April 28, 2010
REDONDO BEACH, Calif. –- NASA's Northrop Grumman-built (NYSE:NOC) James Webb Space Telescope has passed its most significant mission milestone to date, the Mission Critical Design Review, or MCDR. This signifies the integrated observatory will meet all science and engineering requirements for its mission.
"I'm delighted by this news and proud of the Webb program's great technical achievements," said Eric Smith, Webb telescope program scientist at NASA Headquarters in Washington. "The independent team conducting the review confirmed the designs, hardware and test plans for Webb will deliver the fantastic capabilities always envisioned for NASA's next major space observatory. The scientific successor to Hubble is making great progress."
NASA's Goddard Space Flight Center, in Greenbelt, Md., manages the mission. Northrop Grumman, Redondo Beach, Calif., is leading the design and development effort.
"This program landmark is the capstone of seven years of intense, focused effort on the part of NASA, Northrop Grumman and our program team members," said David DiCarlo, sector vice president and general manager of Northrop Grumman Space Systems. "We have always had high confidence that our observatory design would meet the goals of this pioneering science mission. This achievement testifies to that, as well as to our close working partnership with NASA."
The MCDR encompassed all previous design reviews including the Integrated Science Instrument Module review in March 2009; the Optical Telescope Element review completed in October 2009; and the Sunshield review completed in January 2010. The project schedule will undergo a review during the next few months. The spacecraft design, which passed a preliminary review in 2009, will continue toward final approval next year.
The review also brought together multiple modeling and analysis tools. Because the observatory is too large for validation by actual testing, complex models of how it will behave during launch and in space environments are being integrated. The models are compared with prior test and review results from the observatory's components.
Although the MCDR approved the telescope design and gave the official go-ahead for manufacturing, hardware development on the mirror segments has been in progress for several years. Eighteen primary mirror segments are in the process of cryo-polishing and testing at Ball Aerospace in Huntsville, Ala. Manufacturing on the backplane, the structure that supports the mirror segments, is well underway at Alliant Techsystems, or ATK, in Magna, Utah. This month ITT Corp. in Rochester, N.Y., demonstrated robotic mirror installation equipment designed to position segments on the backplane. The segments' position will be fine-tuned to tolerances of a fraction of the width of a human hair. The telescope's sunshield moved into its fabrication and testing phase earlier this year.
The three major elements of Webb - the Integrated Science Instrument Module, Optical Telescope Element and the spacecraft itself - will proceed through hardware production, assembly and testing prior to delivery for observatory integration and testing scheduled to begin in 2012.
The Webb is the premier next-generation space observatory for exploring deep space phenomena from distant galaxies to nearby planets and stars. The telescope will provide clues about the formation of the universe and the evolution of our own solar system, from the first light after the Big Bang to the formation of star systems capable of supporting life on planets like Earth. The telescope is a joint project of NASA, the European Space Agency and the Canadian Space Agency.

James Webb Space Telescope Core Completes Thermal Testing
James Webb Space Telescope Core Completes Thermal TestingJuly 6, 2009
REDONDO BEACH, Calif. -- Northrop Grumman Corporation (NYSE:NOC) has completed testing on a model of the "core" section of NASA's James Webb Space Telescope (JWST) to validate the observatory's sophisticated thermal modeling and design. The company is leading an industrial team in the design and development of the Webb Telescope for NASA Goddard Space Flight Center.
"This test represents JWST's first large-scale thermal performance and demonstration test after a decade in development," said Martin Mohan, JWST program manager for Northrop Grumman's Aerospace Systems sector. "At this early juncture, it appears that our test objectives were achieved. The team gathered a tremendous amount of data that we'll review over the coming months to assess the implications for the current observatory design."
The Webb Telescope's unique design features a sunshield that separates the observatory into a warm sun-facing side, and a cold side facing away from the sun. The warm side will be subjected to nearly 100,000 thermal Watts of heat from the sun, while the cold, anti-sun side, where the optical telescope element and science instrument module are located, will be cooled passively to as low as -414 degrees Fahrenheit (25 K, or slightly above absolute zero). These elements come together at the observatory's central, or core, region.
The core model built by Northrop Grumman is a thermal facsimile of the Webb Telescope's central region and stands about two stories tall, or 17.5 feet, and 17 feet wide. It consists of the top portion of the spacecraft bus, deployable tower, a truncated but fully tensioned five-layer sunshield, optical telescope element backplane support frame, integrated science instrument module (ISIM) compartment, cable trays, thermal management systems, and ISIM electronics compartment.
Testing was conducted in Northrop Grumman's largest thermal vacuum chamber at the company's space systems manufacturing facilities over nearly six weeks. To simulate the extreme cold JWST will experience in space, Northrop Grumman upgraded the chamber with a gaseous helium-refrigerated shroud and precisely monitored the test with 550 individual temperature sensors. The chamber provided a background operating temperature as low as -435 degrees F (13K).
The telescope operates at temperatures approaching absolute zero to best see the near- and mid-infrared light coming from the very first stars and galaxies.
"I can't overstate how much of a milestone this test represents and the remarkable achievement it is just getting this large test article to flight-like temperatures and gathering the needed data," said Keith Parrish, NASA Goddard Space Flight Center, JWST Deputy Observatory/Sunshield manager. "The fact that it went as smoothly and with as little fanfare speaks volumes to the planning, build quality, facility operations, and foresight of the entire team. This test expands the joint NGAS/NASA institutional knowledge for large cryogenic testing and will contribute to the even more complex flight article testing later in the program."
The Webb Telescope is the next-generation premier space observatory, exploring deep space phenomena such as distant galaxies to nearby planets and stars. It will give scientists clues about the formation of the universe and the evolution of our own solar system, from the first light after the Big Bang to the formation of star systems capable of supporting life on planets like Earth.

James Webb Space Telescope’s First Primary Mirror Segment Meets Full Flight Specifications, Sets Program Landmark
James Webb Space Telescope's First Primary Mirror Segment Meets Full Flight Specifications, Sets Program LandmarkMarch 2, 2010
REDONDO BEACH, Calif. –– The James Webb Space Telescope reached a mission-readiness landmark today when its first primary mirror segment was cryo-polished to its required prescription as measured at operational cryogenic temperatures. This achievement sets the stage for a successful polishing process for the remaining 18 flight mirror segments. Northrop Grumman Corporation (NYSE:NOC) is leading Webb's design and development effort for NASA's Goddard Space Flight Center.
"Many predicted it would take us multiple iterations to successfully polish these mirror segments to achieve the correct optical prescription at the telescope's operating temperatures, but we did it on our first try," said Scott Willoughby, Webb Telescope Program Manager for Northrop Grumman Aerospace Systems. "All our budgets and schedules are based on this and it's a confirmation of the basic plan we proposed ten years ago."
"The completion of cryogenic polishing of the engineering development unit primary mirror segment is a hugely significant milestone for the Webb telescope project that demonstrates that our primary mirror segments can be completed on schedule while meeting the performance necessary for science," said Lee Feinberg, NASA Webb Optical Telescope Element Manager at the Goddard Space Flight Center, Greenbelt, Md.
Cryogenic polishing, or cryo-null figuring, ensures that when the mirror reaches its extremely cold operating temperature, its shape will conform to the exact optical prescription required to collect accurate infrared images of distant stars and galaxies. The engineering development unit mirror, which will be used as a flight spare, was cryotested in the X-Ray and Cryogenic Facility (XRCF) at NASA's Marshall Space Flight Center in Huntsville, Ala. The mirror polishing was performed at Tinsley Laboratories, Inc. in Richmond, Calif. Late last year, the mirror segment met flight requirements at ambient temperatures.
"For validation purposes, we're planning four sets of completely different cross checks and verification tests to authenticate the outcome of the mirror cryotests," said Scott Texter, Northrop Grumman Webb Optical Telescope Element Manager. "If any discrepancies surface, we can then investigate and re-verify."
NASA Marshall and principal optical contractor Ball Aerospace will conduct separate verification tests using different computer generated holographic null tools. NASA Goddard will use its own testing equipment and measurement methods in its clean room; testing at Johnson Space Flight Center will use a reflective null tool manufactured by optical integration and test partner ITT; and polishing partner Tinsley Labs will make measurements using their own independent method of calibrating their computer generated holographic null tools.
The James Webb Space Telescope is the next-generation premier space observatory, exploring deep space phenomena from distant galaxies to nearby planets and stars. The Webb Telescope will give scientists clues about the formation of the universe and the evolution of our own solar system, from the first light after the Big Bang to the formation of star systems capable of supporting life on planets like Earth. Expected to launch in 2014, the telescope is a joint project of NASA, the European Space Agency and the Canadian Space Agency.

Lockheed Martin Solar X-ray Imager to be Launched on NOAA GOES-P Spacecraft
Filed under: Lockheed Martin, Syndicated Industry News, space
March 1, 2010 11:10:00 AM
PALO ALTO, Calif., -- The Solar X-ray Imager (SXI) instrument, designed and built by Lockheed Martin (NYSE: LMT) at its Space Systems Advanced Technology Center (ATC) is ready for flight.
Built for the NASA Goddard Space Flight Center (GSFC) in Greenbelt, Md., SXI is awaiting launch - scheduled for March 2 - on the National Oceanic and Atmospheric Administration (NOAA) GOES-P spacecraft from Cape Canaveral Air Force Station, Fla. SXI is one of a suite of instruments that resides on the current generation of Geostationary Operational Environmental Satellites (GOES).
"It is enormously satisfying to have our third SXI instrument ready for launch and we look forward to seeing it operating on-orbit," said George Koerner, SXI program manager at the ATC. "While the other GOES instruments provide near-constant viewing of the Earth, SXI is designed to view the Sun and provide vital information regarding solar activity."
The SXI will be used to aid NOAA and U.S. Air Force personnel in issuing forecasts and alerts of space weather conditions, and in developing a better understanding of Sun-related phenomena that affect the Earth's environment. Turbulent space weather can affect radio communication on Earth, induce currents in electric power grids and long distance pipelines, cause navigational errors in magnetic guidance systems, upset satellite circuitry and expose astronauts to increased radiation.
SXI will observe solar flares, coronal mass ejections, coronal holes and active regions in the X-ray region of the electromagnetic spectrum. These features are the dominant sources of disturbances in space weather that lead to, for example, geomagnetic storms. SXI will also examine flare properties, newly emerging active regions, and X-ray bright points on the Sun. SXI will provide continuous, near real-time observation of the Sun's corona, acquiring a full-disk image every minute. The images cover a 0.7 degree field of view with 0.0014 degree pixels.
The solar disk, as viewed from Earth, is approximately 0.5 degrees in diameter. By recording solar images every minute, NOAA observers will be able to detect and locate the occurrence of solar flares. This is the name given to the explosive releases of vast amounts of magnetic energy in the solar atmosphere. Since scientists are not yet able to predict the occurrence, magnitude or location of solar flares, it is necessary to continually observe the Sun to know when they are happening.
When a flare erupts, it throws out large clouds of ionized, or electrically charged, gas. A small fraction of the cloud is very energetic and can reach the Earth within a few minutes to hours of the flare being observed. These energetic particles pose a hazard to both astronauts and spacecraft.
Coronal mass ejections, which are often associated with flares, take several days to reach the Earth. Fast, powerful ejections give rise to geomagnetic storms, which can disrupt radio transmissions and induce large currents in power transmission lines and oil pipelines. They have resulted in large-scale failures of the North American power grid and greatly increased pipeline erosion. SXI also will monitor coronal holes -- persistent sources of high-speed solar wind. As the Sun rotates every 27 days, these sources spray across the Earth like a lawn sprinkler and cause recurring geomagnetic storms.
NOAA's environmental satellite system is composed of two types of satellites: Geostationary Operational Environmental Satellites (GOES) for national, regional, short-range warning and "now-casting"; and Polar Operational Environmental Satellites (POES) for global, long-term forecasting and environmental monitoring. Lockheed Martin and its heritage companies built all of the POES satellites going back to the very first weather satellite launch on April 1, 1960, and is currently developing the next generation GOES-R satellite system, with a first launch set for 2015. Both GOES and POES are necessary for providing a complete global weather monitoring system. Both also carry search and rescue instruments to relay signals from people in distress.
The ATC has a 47-year-long heritage of spaceborne solar instruments including the Soft X-ray Telescope on the Japanese Yohkoh satellite, the Michelson Doppler Imager on the ESA/NASA Solar and Heliospheric Observatory, the solar telescope on NASA's Transition Region and Coronal Explorer, the Solar X-ray Imager on the GOES-N and O environmental satellites, the Focal Plane Package on Hinode and an Extreme Ultraviolet Imager on each of the two spacecraft in NASA's Solar Terrestrial Relations Observatory. The laboratory also conducts basic research into understanding and predicting space weather and the behavior of the Sun including its impacts on Earth and climate.
The ATC is the research and development organization of Lockheed Martin Space Systems Company (LMSSC). LMSSC, a major operating unit of Lockheed Martin Corporation, designs and develops, tests, manufactures and operates a full spectrum of advanced-technology systems for national security and military, civil government and commercial customers. Chief products include human space flight systems; a full range of remote sensing, navigation, meteorological and communications satellites and instruments; space observatories and interplanetary spacecraft; laser radar; ballistic missiles; missile defense systems; and nanotechnology research and development.

Northrop Grumman-Built James Webb Space Telescope Sunshield Design Achieves Significant Landmark, Marks Major Mission Progress
Filed under: NASA, Syndicated Industry News, space
REDONDO BEACH, Calif. – Feb. 2, 2010 – The five-layer, tennis court-sized sunshield for the Northrop Grumman Corporation
(NYSE:NOC)-built James Webb Space Telescope has passed its critical design review, certifying that its design is complete and meets mission
requirements. By achieving thermal, deployment and stray-light targets, the sunshield is now ready for manufacturing.
"Passing this review is the culmination of years of intense effort meeting the unique challenges that have defined this mission,"
said Scott Willoughby, Webb Telescope program manager for Northrop Grumman Aerospace Systems sector. "This is the first time a sunshield
of this size and complexity will fly on a space telescope. We've achieved a very significant mission-critical milestone with this
important validation of our sunshield design."
Sunshield manufacturing and test plans were also evaluated and approved as part of the review, which took place Jan. 11-14 at the
company's Redondo Beach, Calif., space systems manufacturing facility. The Observatory is being designed and developed by Northrop Grumman
under contract to NASA Goddard Space Flight Center, Greenbelt, Md.
In preparation for the design review, 18 separate sub-assembly design audits were conducted on the sunshield’s extremely complex
system of latches, tensioners, spreader bars and telescoping boom assemblies. The goal was to validate these sub-assemblies at the system
level and evaluate points where they interface.
"There are no text books or guidelines on how to design and build a deployable sunshield of this size," said Keith Parrish, Webb
telescope Sunshield Manager at NASAGoddard. "Nearly a decade ago, NASA and Northrop Grumman had to start from scratch and literally invent the techniques, materials, and mechanisms needed to do the job. We still have quite the challenge in front of us now that we start into the
fabrication and testing phase, buts it's also a very exciting time."
The Webb telescope's sunshield is a five-layer structure the size of a tennis court. Each of the five membrane layers is about as
thick as a human hair (one to two-thousands of an inch thick) and is made of a polymer-based film called Kapton. The layers are separated
from each other and held in place by spreader bars and deployable booms. The sunshield will absorb and deflect solar light to keep the
telescope operating at cryogenic temperatures so infrared sensors can see into the most distant galaxies.
The Webb telescope is NASA's next-generation premier space observatory, exploring deep space phenomena from distant galaxies to
nearby planets and stars. The Webb Telescope will give scientists clues about the formation of the universe and the evolution of our own
solar system, from the first light after the Big Bang to the formation of star systems capable of supporting life on planets like Earth.
Expected to launch in 2014, the telescope is a joint project of NASA, the European Space Agency and the Canadian Space Agency.
