"This milestone is important as it marks the transition to the integration and testing phase for the Webb telescope's optical telescope element," said Lee Feinberg, Optical Telescope Element Manager for the Webb telescope at Goddard.

The Webb telescope is the world's next-generation space observatory and scientific successor to the Hubble Space Telescope. The most powerful space telescope ever built, Webb will observe the most distant objects in the universe, provide images of the very first galaxies ever formed and study planets around distant stars.
The installation of the giant structural steel optical assembly stand was recently completed at Goddard by Northrop Grumman in Redondo Beach, Calif. and its teammate ITT Exelis, McLean, Va. Northrop Grumman is leading the design and development effort for the telescope under contract to Goddard.
"Due to the excellent efforts of our teammate ITT Exelis, we have completed each of the major elements of equipment required to complete the assembly of the optical flight telescope," said Scott Willoughby, Webb telescope vice president and program manager at Northrop Grumman Aerospace Systems. "With the near completion of the final cryotest for the last six flight mirror segments, we are making great progress on the program."
The U-shaped optical assembly stand is is 24 feet high, 52 feet wide and 41 feet long and weighs 139,000 pounds. Its purpose is to cradle the entire 3.7 metric ton optical telescope and install 18 individual 90 pound mirror segments and other components onto the telescope structure with better than one one-thousandth of an inch precision. The platform has been installed in Goddard's largest clean room where Northrop Grumman and ITT will assemble the telescope in late 2014.
ITT Exelis teammate JPW Companies in Syracuse, N.Y. built the massive structure. Two other ITT teammates supplied other elements of the assembly stand: Cranetech, Inc. designed and built the track system suspended above the stand and Progressive Machine and Design made the robotic arms attached to the track that install the mirror segments. The ITT Exelis team spent a year incrementally building and demonstrating the mirror installation equipment.
"The integration equipment is a critical piece of the Webb telescope program. Over the past three years, ITT Exelis has developed a risk reduction program to demonstrate the key elements of this equipment," said Rob Mitrevski, vice president and general manager, Intelligence, Surveillance and Reconnaissance Systems at ITT Exelis Geospatial Systems. "With the delivery of the assembly stand, all of the equipment is coming together in preparation for the telescope assembly effort."
The Webb telescope is a joint project of NASA, the European Space Agency and the Canadian Space Agency.For more information about the James Webb Space Telescope, visit:

Shape matters when light meets atom

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
