Leonard (Len) Tyler - gifted colleague, mentor, and friend - passed away in Port Townsend, WA, at the age of 82. The cause was late stage Alzheimer's disease. Len was trained as an electrical engineer. His career was based on application of signal processing and related skills to remote sensing of planets. As a leader in the specialized field of radio science, he explored each of the main bodies in the Solar System, the last being Pluto as Principal Investigator during development of the Radio Science Experiment (REX) on New Horizons. During his career he also investigated radiowave scattering from Earth’s ocean surfaces and was a PI or Co-I on the Viking, Voyager, Magellan, Mars Global Express, and Mars Express missions. A memorial is planned on June 5, 2023 at Stanford University, where Len was a Professor in the Electrical Engineering Department. For more information on the memorial, contact Ivan Linscott at linscott@stanford.edu. A short biography of his life may be found at: https://tinyurl.com/b3bsx7bv 2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2 MEPAG STEERING COMMITTEE AND GOALS COMMITTEE OPENINGS - APPLICATIONS DUE APRIL 30, 2023 MEPAG is currently seeking one individual to serve on the Steering Committee (SC), and two individuals to serve on the Goals Committee (GC).

This conference will focus on themes underpinning Space Exploration, with the aim of providing useful input to agencies or other bodies in charge of building programmes. Keynote speeches by leading personalities will address the purposes and policies behind space exploration and provide an overview of the current state of play. Seven sessions will examine aspects fundamental for most exploration projects: 1. Philosophy and cultural motivations 2. Dream missions 3. Towards an environment-friendly approach to Lunar exploration 4. Flying machines 5. Going faster (and further) 6. Water: our quest for "oases" in the Solar System 7. Human-robots collaboration A number of Q&A sessions, together with a wrap-up moderated by SGAC, will aim to give the floor to the audience. Other highlights include a contradictory debate on "Life in the universe: rule or exception?" An ice-breaking cocktail will end the first day and a visit to Thales Alenia Space is planned for the end of the second day.

The Tangent Point calculation computes the point on the ray nearest to the target's surface modeled as an ellipsoid, the point on the target's surface nearest to the tangent point, and a few additional parameters such as illumination angles (incidence, emission and phase), time and local true solar time at one of these points. The locations of both points are optionally corrected for light time and stellar aberration, and may be represented using either Rectangular, Ra/Dec, Planetocentric, Planetodetic, Planetographic, Spherical or Cylindrical coordinates. The support for the Azimuth/Elevation/Range coordinates has been added to various WGC calculations. For more information about WGC, including tutorials and usage examples, please see: https://naif.jpl.nasa.gov/naif/webgeocalc.html.

The goal of the proposed PhD project is to improve our group's atmosphere model by refining the description of the atmospheric contributions by solar wind ions and micro-meteorites. These model improvements are targeted at Mercury and the Moon, but can also be used to study atmospheres of other rocky objects within our Solar System, e.g., asteroids or mineral patches found on icy moons. A first use-case of the refined model will be the simulation of the mineral content in Mercury's atmosphere in preparation for the upcoming BepiColombo measurements. The PhD student will also be involved in the analysis and interpretation of data obtained by BepiColomo, once available, including comparing the measurement data with the obtained model results.

Comments are due by May 17, 2023. A3DI will solicit both standalone instruments and instrument suites to conduct science investigations that can be uniquely accomplished by human deployment of payloads on the surface of the Moon during Artemis III. Deployed instruments consist of autonomous instrument packages installed on the lunar surface by astronauts during extravehicular activities. Proposed deployed instruments must address one or more of the scientific objectives outlined in the Artemis III Science Definition Team (SDT) Report. Proposals must include: - Expected science results - Instrument concept of operations, including why crew are needed for deployment, how the instrument is to be deployed, any special requirements for deployment, an estimate of the crew time needed for deployment, and an overview of the real-time ground-based science support needed to deploy the instrument during EVA - Resource requirements for the proposed investigation including cost, mass, volume, power, telemetry, data transfer need, astronaut interaction, etc. - Demonstration of adherence to basic safety requirements and human factors design.
