SITCOMTN-149: An Interim Report on the LSSTComCam On-Sky Campaign

From 24 October to 11 December 2024, the NSF-DOE Vera C. Rubin Observatory conducted an on-sky campaign using the engineering LSST Commissioning Camera (LSSTComCam) to test the end-to-end functionality of hardware and software, as well as operational procedures. This interim report provides a preliminary technical overview of our understanding of the integrated system performance based tests and analyses conducted during the LSSTComCam on-sky campaign. The objectives are to synthesize what we have learned about the system in a timely way to inform on-going commissioning efforts, and to inform the Rubin science community on the progress of the LSSTComCam on-sky campaign. The report is organized into sections to describe major activities during the campaign, as well as multiple aspects of the demonstrated system and science performance. All of the results presented here are to be understood as work in progress using engineering data and the initial versions of the data processing pipelines; the report is a living document that will be updated as analyses are refined.

Building customizable auto-luminescent luciferase-based reporters in plants

Bioluminescence is a powerful biological signal that scientists have repurposed as a reporter for gene expression in plants and animals. However, there are downsides associated with the need to provide a substrate to these reporters, including its high cost and non-uniform tissue penetration. In this work we reconstitute a fungal bioluminescence pathway (FBP) in planta using a composable toolbox of parts. We demonstrate that the FBP can create luminescence across various tissues in a broad range of plants without external substrate addition. We also show how our toolbox can be used to deploy the FBP in planta to build auto-luminescent reporters for the study of gene-expression and hormone fluxes. A low-cost imaging platform for gene expression profiling is also described. These experiments lay the groundwork for future construction of programmable auto-luminescent plant traits, such as light driven plant-pollinator interactions or light emitting plant-based sensors.

A Feasible Approach for an Early Manned Lunar Landing. Part I: Summary Report of Ad Hoc Task Group Study

This report, in two parts, presents a program development plan for attempting a first manned lunar landing in 1967. The two parts consist of a Summary Report and a Detailed Report representing the coordinated output of the ad hoc task group assigned to the study. The study was started in response to the request for such a study by the Associate Administrator in his memorandum of May 2, 1961 establishing the Ad Hoc Task Group. The purpose of the study was to take a first cut at the tasks associated with the design, development and construction of the equipment and facilities as well as the development of the crews, and to show the time phasing of these tasks. Included are the space science, life science and advanced technology tasks whose data and results are needed for designing and developing the systems required in carrying out the mission.

A reinterpretation of the reported energetic particle fluxes in the vicinity of Mercury

During the Mercury flyby of Mariner 10, observations of large fluxes of energetic electrons (energies in excess of 0.3 MeV) and protons (energies between 0.53 and 1.9 MeV) were reported by Simpson et al. (1974). The reported simultaneous enhancements of protons and electrons in the magnetic field of Mercury have raised some perplexing planetology questions. It is shown here that the response of the proton detector in the Mariner 10 experiment is most plausibly attributable to the pileup of low-energy electrons rather than the presence of protons in the vicinity of Mercury. Further, the reported lower-limit electron differential spectrum exponent of at least 9 and the 300-keV electron fluxes are probably in quantitative error, especially where the count rates are highest. It is concluded that no 'new' acceleration mechanism has been identified at Mercury.

STARPAHC Interim Evaluation Report, May 1975 - April 1976

The primary goals of the STARPAHC Program are to provide data for developing health care for future manned spacecraft, and to establish the feasibility of the STARPAHC concept for improving the delivery of health care to remote areas on earth. Accordingly, the hardware and medical evaluations initiated during the first 6 months of system operation were continued and expanded during the second 6-month period. The evaluations are based on what has proven to be a relatively stabilized 6-month period wherein system failures which occurred during the initial shakedown period in the first 6 months have been minimized. Early trends and performance data reported in the first semi-annual report were reexamined to either verify, modify or change earlier conclusions. The highlights are given of the total year of operation with emphasis on comparisons between the first and second semi-annual reporting period. In addition, an early analysis of costs is summarized.

NASA aviation safety reporting system

A decline in reports concerning small aircraft was noted; more reports involved transport aircraft, professional pilots, instrument meteorological conditions, and weather problems. A study of 136 reports of operational problems in terminal radar service areas was made. Pilot, controller, and system factors were found to be associated with these occurrences. Information transfer difficulties were prominent. Misunderstandings by pilots, and in some cases by controllers, of the policies and limitations of terminal radar programs were observed.

A search for the reported 400-keV gamma-ray line from Crab Nebula

A balloon-borne large volume high resolution gamma-ray spectrometer which utilizes 40 cu cm Ge(Li) crystals was used June 10, 1974 to search for a 400-keV gamma-ray line from the Crab Nebula. Energy loss spectra in the 400-keV vicinity are compared with gamma-ray measurements of the same source which were reported by Leventhal et al. (1977). In contrast with the 1976 experimental results reported by Leventhal et al., a 400-keV line was not observed. Further, it is thought that the 1974 data contradict the measurement reported by Leventhal et al. if a constant source intensity is assumed.
