    Space activities are expanding. The number and types of actors who are involved with outer space is growing. This expansion has significant technological, environmental, and financial implications for the industry. After the research and development of a satellite itself and the provision of launch services, insurance is the third greatest expense to put a satellite into orbit. Though 95% of insured satellites in the last few years have been in geostationary orbit, the greater use of other Earth orbits is leading to an increase in demand for insurance in these orbits. There are a number of innovative actions that space insurers can take to both grow their business and ensure the sustainable development of the space industry. Insurers can purchase space traffic management services (for example, from ComSpOC) as a centralized point of contact for their insureds. With technical expertise, they can advise insureds regarding recommended debris avoidance maneuvers to mitigate risk. They can provide consultation on design and incentives for greater tracking and maneuvering capabilities to be installed on insured satellites. Insurers can also provide launch weather and space weather services to mitigate the risk of a claim. In this paper, I will discuss these options for space insurers. In doing so, I will analyze aspects of liability for space objects from a legal perspective, both under the international space law regime and in the United States in particular. The ultimate goal of the paper is to provide recommendations that can be implemented moving forward

    Planning Related to the Curation and Processing of Returned Martian Samples

    The Astromaterials Acquisition and Curation Office (henceforth referred to herein as NASA Curation Office) at NASA Johnson Space Center (JSC) is responsible for curating all of NASAs extraterrestrial samples. Under the governing document, NASA Policy Directive (NPD) 7100.10E Curation of Extraterrestrial Materials, JSC is charged with the curation of all extraterrestrial material under NASA control, including future NASA missions. The Directive goes on to define Curation as including documentation, preservation, preparation, and distribution of samples for research, education, and public outreach. Here we describe some of the ongoing planning efforts in curation as they pertain to the return of martian samples in a future, as of yet unplanned, mission

    The Astromaterials Acquisition and Curation Office at NASA Johnson Space Center (henceforth AACO) is responsible for receiving and curating all of NASAs extraterrestrial samples, current and future (as per NASA Policy Directive (NPD) 7100.10E Curation of Extraterrestrial Materials). As such, the AACO coordinates sample capture, containment, and transportation to the curation facility as well as documents, preserves, prepares, and distributes all of the samples within NASAs astromaterial collections for research, education, and public outreach. Since the lunar rock and soil samples returned during the Apollo Program, NASAs first Class V Restricted Earth Return Missions, the AACO curates six other astromaterials collections. Lessons learned from each collection and respective missions (e.g. Apollo, Genesis, Stardust) as well as advancements in science and technology have informed the AACOs plan for acquiring and curating Martian samples. Given the nature of the collection, a mobile and modular facility is recommended. The two broad requirements a Mars sample facility must maintain are: 1) the ability to contain the samples to protect the public from exposure of an unknown unknown biological agent and 2) ensure the scientific integrity of the samples are maintained (while maximizing scientific outcome). Although Apollo samples were eventually deemed safe and released to the scientific community for evaluation, there is no guarantee that this will be the case for Martian samples. Therefore, the facility in which the samples will be contained and investigated must be modular and able to accommodate an array of instrumentation that could be highly variable depending on the initial scientific outcomes. Furthermore, in order to facilitate proper sample capture and containment upon landing as well as sample distribution to other laboratories with proper containment, a mobile facility is a valuable investment

    Amyotrophic Lateral Sclerosis in a Patient with a Family History of Huntington Disease: Genetic Counseling Challenges

    Full text link
    Amyotrophic lateral sclerosis (ALS) and Huntington disease (HD) are generally considered to be distinct and easily differentiated neurologic conditions. However, there are case reports of the co‐occurrence of ALS with HD. We present a 57‐year‐old male with a clinical diagnosis of sporadic ALS in the context of a family history of HD. This case adds to the limited literature regarding individuals with a family history of HD who present with features of ALS. There were several genetic counseling challenges in counseling this patient including the diagnostic consideration of two fatal conditions, complex risk information, the personal and familial implications, and the patient’s inability to communicate verbally or through writing due to disease progression. DNA banking effectively preserved the right of our patient and his wife not to learn his HD genetic status during a stressful time of disease progression while providing the option for family members to learn this information in the future if desired. We present lessons learned and considerations for other clinical genetics professionals who are presented with similar challenging issues.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/147074/1/jgc40725.pd

    Applying Memory Science to the Classroom: Effects of Reading Questions and Answer Keys on Test Scores

    Get PDF
    Instructors and students are constantly searching for effective ways to increase reading comprehension. Cognitive science would suggest that both additional assessment as described by the testing effect and timely feedback would increase comprehension. Our study investigated the effect of assigning reading questions on the quiz scores of undergraduate students. We also examined the effect of giving students an answer key versus verbal feedback on final quiz scores. Prior to the intervention, students completed a reading and then were given a pre-test group activity and post-test during class. Researchers selected certain class sections to complete ungraded questions prior to class as well as selecting sections to receive answer keys during the group activity. We found that students who completed reading questions had significantly higher initial quiz scores than those who did not complete reading questions. Results also showed that students who had an answer key during their class activity scored significantly higher on their final quiz than those who reviewed the answers with an instructor. This research provides insight into maximizing student tests scores and improving reading comprehension. This technique can be applied to fields outside of an educational setting to increase initial understanding of material

    Mobile/Modular BSL-4 Containment Facilities Integrated into a Curation Receiving Laboratory for Restricted Earth Return Missions

    NASA robotic sample return missions designated Category V Restricted Earth Return by the NASA Planetary Protection (PP) Office require sample containment and biohazard testing upon return to Earth. Since the 1960s, sample containment from an unknown extraterrestrial biohazard have been related to the highest containment standards and protocols known to modern science. Today, this is Biosafety Level (BSL) 4 containment. In the U.S., the Biosafety in Microbiological and Biomedical Laboratories publication authored by the U.S. Department of Health and Human Services (HHS): Public Health Service, Centers for Disease Control and Prevention, and the National Institutes of Health houses the primary recommendations, standards, and design requirements for all BSL labs. Past mission concept studies for constructing a NASA Curation Receiving Laboratory with an integrated BSL-4 quarantine and biohazard testing facility have been estimated in the hundreds of millions of dollars (USD). As an alternative option, we have conducted a trade study for constructing a mobile and/or modular sample containment laboratory that would meet all BSL-4 and planetary protection standards and protocols at a fraction of the cost. Mobile and modular BSL-2 and 3 facilities have been successfully constructed and deployed world-wide for government testing of pathogens and pharmaceutical production. Our study showed that a modular BSL-4 construction could result in ~ 90% cost reduction when compared to traditional BSL-4 construction methods without compromising the preservation of the samples or Earth. For the design/construction requirements of a mobile/modular BSL-4 containment, we used the established HHS document standards and protocols for manipulation of agents in Class III Biosafety Cabinets (BSC; i.e., negative pressure gloveboxes) that are currently followed in operational BSL-4 facilities in the U.S
