These instruments were conceived and built at NASA's Goddard Space Flight Center in Greenbelt, Md., and were integrated to the satellite and tested at NASA's Marshall Spaceflight Center, Huntsville, Ala.
MINI-ME, acronym for Miniature Imager for Neutral Ionospheric atoms and Magnetospheric Electrons, is a low energy neutral atom imager which will detect neutral atoms formed in the plasma population of the Earth's outer atmosphere to improve global space weather prediction. Low energy neutral atom imaging is a technique first pioneered at Goddard which allows scientists to observe remotely various trapped charged particle populations around Earth that we would normally only be able to observe in-situ through direct instrument contact with the particles.Michael Collier, Principal Investigator for the MINI-ME instrument at NASA Goddard said, "The satellite has gone through vibration, thermal, and Electromagnetic Interference (EMI) tests and everything looks great. The MINI-ME instrument is performing as expected."
Doug Rowland, PISA's Principal Investigator at NASA Goddard said, "PISA has completed the same tests that the Mini-ME endured and has just passed powered Electromagnetic Interference Test. PISA is on track for spacecraft to be packed up and delivered to the launch site." The EMI, vibration and thermal testing are critical tests for all instruments and satellites before they're loaded aboard a rocket and put into orbit.
The Thermospheric Temperature Imager, or TTI, will provide the first global-scale measurements of thermospheric temperature profiles in the 56-168 mile (90-270 km) region of the Earth's atmosphere. The temperature profile sets the scale height of the thermosphere which determines the density at orbital altitudes and therefore the aerodynamic drag experienced by military spacecraft.
John Sigwarth, TTI's Principal Investigator at NASA Goddard, said "The TTI survived the satellite launch vibration levels, being blasted with radio waves, and the TTI had a great thermal vacuum test. We were able to characterize the operation of the instrument in space-like environments and the TTI is ready for launch. We are eagerly anticipating obtaining great data from orbit."
Electromagnetic Interference or EMI testing is done to ensure that powerful ground-based communications and radar systems do not cause interference on the satellite or instrument systems.
Vibration testing is an important part of the testing process, because when the rocket carrying the satellite lifts off and travels through Earth's atmosphere it experiences intense vibrations. Successful vibration testing assures scientists and engineers that their instrument will remain intact and fully functional after launch.
Thermal testing is also critical, because of the extreme temperatures in space. Scientists need to be sure that the instruments will maintain function at extreme temperatures, from the extreme heat the rocket carrying the satellite will experience during launch and when it travels through Earth's atmosphere into the cold void of space.
"With the completion of the last phase of environmental testing of the integrated FASTSAT-HSV01 spacecraft, our team is focused on readying the satellite and its six science and technology instruments, for its near term shipment to Kodiak, Alaska, and for an on time launch no earlier than May 28, 2010," said FASTSAT Project Manager Mark Boudreaux at NASA Marshall.
"FASTSAT-HSV" means "Fast, Affordable, Science and Technology Satellite, Huntsville" The development, integration, test and operations of the three instruments is a collaborative effort between NASA Goddard, NASA Marshall, and the U.S. Naval Academy, Annapolis, Md.
FASTSAT-HSV01 will be flying a total of six instruments approved by the U.S. Department of Defense (DoD) Space Experiments Review Board multi-spacecraft/payload mission named STP-S26, which is executed by the DoD Space Test Program (STP) at the Space Development and Test Wing (SDTW), Kirtland Air Force Base, N.M. which is a unit of the Air Force Space and Missile Systems Center. The mission was designated S26 to correspond to the 26th small launch vehicle mission in STP's more than 40 year history of flying DoD space experiments. The mission will launch four satellites and three cubesats into low earth orbit.
The satellite was created at NASA Marshall with the Von Braun Center for Science and Innovation, in partnership with Dynetics, a corporate partner.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
