Utah FORGE Raw Microgravity Composite Data: Updated 10/2021.

This is a microgravity dataset from the Utah FORGE site near Milford, Utah. This composite dataset was updated in October, 2021 and contains data from December 17th, 2018 through September 24th, 2021. The data includes the GPS location of the measurement, date of the measurement, name of the station, relative difference in gravity, and coordinates of the station. This data was generated by the Utah Geological Survey.

Utah FORGE: Phase 3 Microgravity Data

A 4D microgravity survey began in early 2019 in order to benchmark surface and subsurface elevations prior to Phase 3 drilling and stimulation campaigns. Microgravity stations are collocated with GPS deformation benchmarks and use the same location survey data. Surveys are undertaken on a quarterly basis. The focus of current activities is comparative analysis of GPS survey results and InSAR analysis (see GDR Submission 1251) to check seasonal variance and to evaluate possible changes in the groundwater elevation. The attached zip file contains a text file and an Excel spreadsheet containing Utah FORGE Phase 3 processed "final" microgravity data through time. The data are identical in both files. The spreadsheet is only supplied for convenience. There is also a ReadMe.txt file that describes the field headings.

Uncovering Unique Molecular Adaptations in the Arabidopsis Thaliana Cvi-0 Ecotype

This research proposal aims to investigate the unique molecular adaptations exhibited by Arabidopsis Thaliana, specifically focusing on the Cape Verde Islands (Cvi-0) ecotype, in response to microgravity conditions. The study examines data from NASA’s Open Science Data Repository and applies a multifaceted RNAseq analysis pipeline using tools in the UseGalaxy.org open platform. Through transcriptomic analysis, differential gene expression patterns were identified in Cvi-0, revealing an absence of heat shock protein (HSP) upregulation and an upregulation of Rubisco Activase (RCA) and chloroplast-related pathways. To test the hypothesis that these adaptations may contribute to Cvi-0’s increased adaptability in microgravity, a three-fold experimental design is proposed. Four experimental groups will be cultivated under simulated microgravity and ground control conditions, including Cvi-0, Col-0, and genetically modified Col-0 with silenced HSP genes, and genetically modified Col-0 with upregulated RCA gene. Growth parameters will be measured to assess plant resilience, and RNA sequencing will provide transcriptomic data for pathway analysis. Anticipated outcomes include improved markers of plant health (mass, growth, etc.) of Cvi-0 in simulated microgravity and enhanced resilience in genetically altered Col-0 variants, providing insights into potential mechanisms of adaptation. This research would bear significance for space agriculture, nutrition for extended space missions, and sustainable terrestrial crop enhancement. Moreover, the insights gained could reshape crop engineering on Earth, enhancing robustness to climate induced stresses and bolstering global food security. The proposal’s trajectory blends scientific curiosity with practical applicability, forging a path towards sustainable food production and improving human exploration beyond our planet.

Materials Safety - Not just Flammability and Toxic Offgassing

For many years, the safety community has focused on a limited subset of materials and processes requirements as key to safety: Materials flammability, Toxic offgassing, Propellant compatibility, Oxygen compatibility, and Stress-corrosion cracking. All these items are important, but the exclusive focus on these items neglects many other items that are equally important to materials safety. Examples include (but are not limited to): 1. Materials process control -- proper qualification and execution of manufacturing processes such as structural adhesive bonding, welding, and forging are crucial to materials safety. Limitation of discussions on materials process control to an arbitrary subset of processes, known as "critical processes" is a mistake, because any process where the quality of the product cannot be verified by inspection can potentially result in unsafe hardware 2 Materials structural design allowables -- development of valid design allowables when none exist in the literature requires extensive testing of multiple lots of materials and is extremely expensive. But, without valid allowables, structural analysis cannot verify structural safety 3. Corrosion control -- All forms of corrosion, not just stress corrosion, can affect structural integrity of hardware 4. Contamination control during ground processing -- contamination control is critical to manufacturing processes such as adhesive bonding and also to elimination foreign objects and debris (FOD) that are hazardous to the crew of manned spacecraft in microgravity environments. 5. Fasteners -- Fastener design, the use of verifiable secondary locking features, and proper verification of fastener torque are essential for proper structural performance This presentation discusses some of these key factors and the importance of considering them in ensuring the safety of space hardware.

Space Studies Board Annual Report, 2008

The year 2008 was an historic one for both our country and the Space Studies Board (SSB). The United States elected a new president. His first task has been to cope with an economic crisis of historic proportions. In the same year, the United States celebrated the 50th anniversary of its first spaceflight, and the SSB celebrated its 50th anniversary. As we in the space community looked back, we also looked forward. The year 2008 was truly a year of transition, for the country and for the space enterprise. Under Lennard Fisk's continued leadership, the SSB completed its year-long seminar series, Forging the Future of Space Science, which highlighted the accomplishments of space science over the past 50 years and looked ahead to the next 50 years of discoveries that await us. During the first half of the year, events were held in Tallahasse, Florida; Austin, Texas; Paris, France (in conjunction with the Committee on Space Research, which is headquartered here); Boulder, Colorado; and Fairmont, West Virginia. The series culminated in a celebration at the National Air and Space Museum in Washington, D.C., on June 26, .50 years to the day after the SSB was created. At that event, the Board presented its first James A. Van Allen Lectureship to Frank McDonald. The recent economic crisis has made it obvious that the U.S. economy does not stand alone. The global economy is becoming more and more integrated. The space enterprise cannot avoid this trend. In November, the SSB conducted a workshop in conjunction with the Aeronautics and Space Engineering Board entitled 'Future International Space Cooperation and Competition in a Globalizing World'. Its goals were to assess the current state of international cooperation and competition in space and to discuss ways in which new and emerging space powers might be better integrated into the global space community.
