CALL FOR ABSTRACTS
NASA TEERM Demonstrates an Innovative Site Characterization and Remediation Technology
NASA TEERM is working with Stennis Space Center (SSC) and the developer of an innovative site characterization and remediation technology to address subsurface contamination at SSC. The technology, a combination of multiport groundwater sampling and remedial reagent injection well, is being demonstrated on an area of contaminated groundwater. The newly-developed well technology was installed using Horizontal Directional Drilling (HDD) techniques and will allow for more accurate determination of the discrete locations and magnitudes of contaminant sources when compared to traditional wells installed either horizontally or vertically. The innovative design will serve a dual purpose; a site characterization well to identify contaminant sources and then as a remediation well to precisely inject chemicals that will destroy those sources.
Next phase of TEERM Hexavalent Chrome-free Coatings for Electronics Project is underway.
Working jointly with technical representatives from NASA, the Department and Defense, and industry, the Technology Evaluation for Environmental Risk Mitigation (TEERM) Principal Center is evaluating the suitability of trivalent chromium conversion coatings for use in applications where high-frequency electrical performance is important. This project is assessing the performance of trivalent chromium pretreatments against a hexavalent chrome pretreatment control material before and after environmental exposure. TEERM is currently working project stakeholders to finalize the test plan for this project.
International Meetings with DLR and ESA
NASA TEERM, along with HQ Senior Managers from the Environmental Management Division, participated in meetings with the German Aerospace Center (DLR) in Cologne, Germany and the European Space Agency and Technology Center in Noordwijk, Netherlands. The meetings with DLR resulted in opportunities that are of mutual interest in evaluating environmental technologies. The scope of these activities fit within an existing agreement between NASA and DLR. The importance of meeting with ESA was to discuss several topics, including the status of an international agreement between NASA and ESA in support of joint testing. Additional benefits from meeting face-to-face with our international partners were the verbal commitments to participate in the 12th Annual International Workshop on Environment and Alternative Energy, October 21 - 24, 2014 at the Kennedy Space Center Visitor Complex.
Hydrogen Fuel Cell Electric Bus
TEERM assisted with the acquisition of a low-mileage hydrogen fuel cell electric bus that was transported from the U.S. Department of Energy, Sandia National Laboratory. The bus is located at the KSC Ground Operations Demonstration Units site with plans to use it as a components-level test bed for evaluating novel technologies for energy generation and storage. Future plans may include occasional VIP transportation. To transport the bus from its DoD demonstration site in Washington state, NASA only had to cover the transportation costs. KSC is developing a near term assessment plan of the bus condition and adaptability to the proposed test bed usage. An engineer from the bus manufacturer, Proterra, will be visiting in April to address any questions or concerns with the vehicle.
Lead-free (Pb) Electronics Risk Management (PERM) Council Meeting Hosted by KSC and TEERM
The NASA Technology Evaluation for Environmental Risk Mitigation (TEERM) Principal Center hosted a Lead-free (Pb) Electronics Risk Management (PERM) Council meeting February 11 – 13 at NASA Kennedy Space Center, Florida. PERM is comprised of members representing industry, Government and academic organizations who have a common interest in managing the risks of Pb-free electronics in aerospace, defense, and high performance electronic systems. This was the 19th PERM meeting that typically occurs on a tri-annual basis where the council members take a turn planning and hosting the meeting. Participants, including TEERM, presented their latest findings and recommendations from their respective Pb-free electronics risk management activities. There were 65 attendees representing 40 different organizations, both domestic and foreign.
Backup Power Fuel Cells at KSC
TEERM has helped NASA Kennedy Space Center secure three backup fuel cells from an energy technology demonstration program managed by the U.S. Army Construction Engineering for the U.S. Department of Energy. The 15KW fuel cells (one 6KW, one 5KW, one 4KW) are brand new and were never used. The units are now at KSC and will be used to evaluate the effectiveness and reliability of fuel cells for backup power.
2013 INTERNATIONAL WORKSHOP ON ENVIRONMENT AND ALTERNATIVE ENERGY WAS A GREAT SUCCESS!
NASA and European partners held the 11th annual International Workshop on Environment and Alternative Energy, October 22 – 25, 2013 at The European Space Agency (ESA)'s European Space Research Institute (ESRIN) facility in Frascati, Italy. The theme of the workshop was "Increasing Space Mission Resiliency through Sustainability." This event was supported by the European Space Agency (ESA), the Portuguese Center for Pollution Prevention (C3P), and the Fundação Luso Americana (FLAD). U.S. and international subject matter experts presented on the topics of Increasing Space Mission Critical Ground Infrastructure Resiliency through Sustainability, and Environmentally-Driven Changes to Aerospace Materials & Process Management including Corrosion Protection and Registration, Evaluation, Authorization and Restriction of Chemical (REACH) Regulation. The workshop also included a panel discussion on the topic of Sustainability as a Policy Tool. Awards are typically given to the three student poster presentations judged to be the best; however, this year’s student poster presentations were so excellent, that the judges could not narrow it down to only three, so four students were given awards.
NASA Alternatives to Hexavalent Chrome Containing Coatings Demonstration – Wallops Flight Facility P-3 Aircraft
A joint Technology Evaluation for Environmental Risk Mitigation (TEERM) project with NAVAIR's Materials Engineering Division has begun flight testing hexavalent chrome free coatings on exterior components of two NASA aircraft. Seven of nine aluminum access panels are fully hexavalent chrome free and two components serve as controls with hexavalent chrome pretreatments and primers. The components were installed in late 2012 and initial inspection on the P-3 aircraft took place in early 2013, only a short time after the components had been placed on vehicle. The second inspection of NASA's P-3 at Wallops Flight Facility took place in July 2013. Engineers inspected the panels for signs of corrosion and wear and took measurements of color, gloss and coating thickness. After over six months of exposure on the aircraft, and 307 flight hours, all coatings are performing well with no deleterious effects. The next inspection will take place in the 4th quarter of 2013 when the P-3 returns to Wallops Flight Facility. Additionally, a second aircraft, NASA's C-23 Sherpa will also be inspected in the 4th quarter of 2013. It was not inspected in July as it is still on mission in Alaska.
Ground Support Development and Operations (GSDO) Program Hexavalent Chrome Alternatives
The NASA TEERM Ground Support Development and Operations (GSDO) Program Hexavalent Chrome Alternatives Project is evaluating and testing non-chromated pretreatments as replacements for hexavalent chrome pretreatments used on Ground Support Equipment (GSE) and Electrical Ground Support Equipment (EGSE). Following 35 days of exposure at the KSC Beachfront and ambient office storage, the test articles were evaluated for electrical bonding properties. To date, the non-chromated pretreatments have been outperforming the hexavalent chrome pretreatments. Testing continues and the test articles will be evaluated again following 70 days of exposure at the KSC Beachfront and ambient office storage.
