STEREO spacecraft arrives at NASA Goddard for final testing

10.11.2005


The two Solar TErrestrial RElations Observatory (STEREO) spacecraft arrive at the NASA Goddard Space Flight Center in Greenbelt, Md. on Nov. 9 for major testing as they near completion. Set to launch in Spring 2006, STEREO is the first mission to image the sun and solar wind in 3-D. This new view is critical to improving our understanding of space weather and its impact to space and on Earth systems.

During its two-year mission, the two nearly identical spacecraft will explore the origin, evolution, and interplanetary consequences of coronal mass ejections (CMEs), the most violent explosions in our solar system. When directed at Earth, these billion-ton eruptions can disrupt satellites, radio communications, and power systems. In addition, energetic particles associated with CMEs are a serious hazard to spacecraft and astronauts.

"The arrival of both observatories at GSFC is a critical milestone for the STEREO project. The fully integrated observatories look great and represent a lot of hard work from a very dedicated APL/GSFC team. The next few months will be exciting as we put them through a rigorous space simulation test program in preparation for launch," said Mark Jarosz, Observatory Manager for the STEREO Project at NASA Goddard.


Upon arrival, the spacecraft will undergo multiple mechanical assembly and electrical tests to verify readiness for launch both in a stacked configuration, and on their own. Tests will simulate launch noise, space temperature variations, launch vibrations and validate the explosive nut used to separate the two satellites in orbit. Engineers also plan to deploy the high gain antenna, and ensure that radio emissions from the satellites don’t interfere with other sensitive scientific instruments like the S/WAVES radio astronomy experiment.

STEREO’s launch window extends from April through June 2006 at the Cape Canaveral Air Force Station (CCAFS), Fla. Truly an international effort, its instruments were built and shipped from the United States and several European countries. The observatory integration was performed at The Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md. Testing is being conducted both at APL and at NASA.

"STEREO is going to help us answer some of the biggest questions about the sun. Not only will we see if CMEs are moving toward Earth, but we’ll see how they move through the solar system," said Dr. Michael Kaiser, Project Scientist for STEREO at the Goddard Space Flight Center.

Im Focus: Significantly more productivity in USP lasers

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:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

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...

Im Focus: Quantum Particles Form Droplets

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...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

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,...
