The Solar Wind Electron Analyzer (SWEA) was the last of the six instruments to be delivered, and was integrated late last week at Lockheed Martin in Littleton, Colo. SWEA measures the properties of electrons at Mars, one electron at a time, and can process up to one million events per second.
NASA’s MAVEN spacecraft undergoes acoustics testing on Feb. 13, 2013 at Lockheed Martin Space Systems’ Reverberant Acoustic Laboratory. The environmental test simulates the maximum sound and vibration levels the spacecraft will experience during launch. MAVEN is the next mission to Mars and will be the first mission devoted to understanding the Martian upper atmosphere. Credit: Lockheed Martin
The other instruments in the package had been delivered earlier. In addition to the SWEA instrument, the package includes the Solar Wind Ion Analyzer (SWIA), Suprathermal and Thermal Ion Composition (STATIC), Solar Energetic Particle (SEP), Langmuir Probe and Waves (LPW), Magnetometer (MAG), and a data-processing unit.
"The Particles and Fields Package is designed to study the solar wind interaction with Mars and the structure and dynamics of Mars' ionosphere, including the influence of Mars' strongly magnetized crust," said David L. Mitchell, SWEA instrument lead and coordinator for the full package, from the University of California, Berkeley/Space Sciences Laboratory (SSL). "The package measures solar ultraviolet flux, solar wind properties, and energetic particles produced in solar storms to help us understand how the Sun influences the upper atmosphere and drives atmospheric escape."
The package was built by the University of California, Berkeley/Space Sciences Laboratory (SSL) with support from the University of Colorado Boulder/Laboratory for Atmospheric and Space Physics (CU/LASP) and NASA's Goddard Space Flight Center.
"The final components of the science payload are coming together, so we’re getting closer to being ready for launch," said Bruce Jakosky, MAVEN principal investigator from CU/LASP. "I look forward to the exciting and diverse science results that the Particles and Fields Package instruments will provide.”
The MAVEN spacecraft will carry two other instrument suites. The Remote Sensing Package, built by CU/LASP, will determine global characteristics of the upper atmosphere and ionosphere. The Neutral Gas and Ion Mass Spectrometer, provided by NASA Goddard, will measure the composition and isotopes of neutral ions.
“We’re in the home stretch now of completing the assembly and test of the spacecraft. With the full complement of Particles and Fields Package instruments now onboard the spacecraft, we are in a very good position for delivering the spacecraft to the launch site on schedule in August”, said David F. Mitchell, MAVEN project manager from NASA’s Goddard Space Flight Center in Greenbelt, Md.
MAVEN is scheduled for launch in November, 2013. It is the first spacecraft devoted to exploring and better understanding the Martian upper atmosphere. MAVEN will investigate the role that loss of Mars' atmosphere to space played in determining the history of water on the surface.
MAVEN’s principal investigator is based at the University of Colorado at Boulder's Laboratory for Atmospheric and Space Physics. The university provides science instruments and leads science operations, and Education and Public Outreach. NASA's Goddard Space Flight Center manages the project and provides two of the science instruments for the mission. Lockheed Martin of Littleton, Colo., built the spacecraft and is responsible for mission operations. The University of California at Berkeley Space Sciences Laboratory provides science instruments for the mission. NASA’s Jet Propulsion Laboratory, Pasadena, Calif., provides navigation support, the Deep Space Network, and the Electra telecommunications relay hardware and operations.

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,...
Broadband rotational spectroscopy unravels structural reshaping of isolated molecules in the gas phase to accommodate water

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
