LSU Student Astronomers Assisting in Development of New Lunar-Based Telescope

Student astronomers at Louisiana State University are researching and designing a new type of lunar telescope that aims to take new images of the far side of the moon by 2024, as per this article from LSU.

The collaboration is called L-CAM1, and it’s a scientific observing program that’s being worked on by faculty and student astronomers from LSU, Mississippi State University, the SETI Institute, and AstronetX PBC, a public benefit corporation that’s dedicated to enabling frontier research from space. One of the main goals of the scientific observing program collaboration is for LSU students to research and design the creation of the first lunar-based camera.

The photographic instrument, which will be called Astronet L-CAM1, will be designed to capture cosmic images from the moon for research purposes that will contribute to the areas of astrophysics, planetary defense, and planetary science.

Assistant Professors Tabetha Boyajian and Matthew Penny from LSU’s Department of Physics & Astronomy recruited a team of students to work on the Astronet L-CAM1. In speaking on the magnitude of the selection process, LSU Department of Physics & Astronomy assistant professor Tabetha Boyajian said, “giving early-career students the chance to design a frontier, space-based science program that will be operated on the lunar surface is a wonderful and unique opportunity to support the progression of tomorrow’s leading astronomers and astrophysicists.”

When starting to plan the L-CAM1, LSU students had to first develop a complex understanding of the limitations and benefits that present themselves when it comes to lunar observation. The students and faculty then decided to focus on two primary scientific cases for the observing program: to improve the characterization of previously-known exoplanets and to expand asteroid observation and characterization.

Whenever an orbiting exoplanet briefly passes in front of a star, space-based observatory instruments such as the Astronet L-CAM1 will be able to allow for high-precision measurements of parent star brightness changes. Because the L-CAM1 will be able to observe these changes without interruptions over a lunar day (which is equivalent to 14 Earth days,) this instrument will be able to have long, uninterrupted observing sequences of exoplanet transit events. Additionally, during a typical multi-lunar day mission, the L-CAM1 will be able to observe approximately 200 asteroids, which would include nearly one near-Earth asteroid per month.

Senior planetary astronomer at the Carl Sagan Center at SETI Frank Marchis said of what is needed from the student research team, “our student team first needed to create simulations of the portion of lunar sky L-CAM1 will see during the multiple lunar days of the mission as a way of determining visible astrophysical and astronomical targets. One of the unique benefits L-CAM1 will provide is the duration of uninterrupted time individual subjects can be observed.”

Funding for the scientific program’s planning comes from the Gordon and Betty Moore Foundation to AstronetX along with additional support for student participation that’s been provided by the National Science Foundation’s Research Experiences for Undergraduates program at LSU.

AstronetX is a Delaware public benefit corporation that’s based in Boston, Massachusetts, and they were established to facilitate and enable research in the Earth and space sciences for the overall benefit of humanity by making multi-purposeful space-based observational and database services available to customers. Their customer base includes the space science community, government agencies, the private sector, and citizen scientists.

Farzaneh Zohrabi studies at LSU as a L-CAM1 graduate student science team member. In speaking on the student astronomers being selected to work on the project, Zohrabi said, “working on L-CAM has been a dream come true for me. I’ve been an astronomer since I was 13, and now I’m developing the science program for a lunar surface telescope. This is a frontier science project, starting with getting to speak with the engineers and discussing how the different camera designs being considered will influence the data we’ll capture. A unique thing that we’re planning to do with L-CAM makes really precise measurements of nearby bright stars and their exoplanets. This is something that cannot easily be done using ground-based telescopes on Earth because of the atmosphere and saturation limits.”
