Conceptual Design of the Lunar Crater Radio Telescope (LCRT) on the Far Side of the Moon
In this paper, we present the conceptual design of a Lunar Crater Radio Telescope (LCRT) on the far side of the Moon. We propose to deploy a wire mesh using wall-climbing DuAxel robots in a 3–5 km diameter lunar crater on the farside, with a suitable depth-to-diameter ratio, to form a parabolic reflector with a 1 km diameter. LCRT will be the largest filled-aperture radio telescope in the Solar System. LCRT could enable scientific discoveries in the field of cosmology by observing the early Universe in the 10–50 m wavelength band (i.e., 6-–30 MHz frequency band), which has not been explored for cosmological observations to date. We have described LCRT’s science objectives and key technology challenges, that we need to overcome to make this concept a reality. We envisage that LCRT will open a new window for humanity’s exploration of the Universe.
Magnetic Fields of Extrasolar Planets: Planetary Interiors and Habitability
Jupiter’s radio emission has been linked to its planetary-scale magnetic field, and spacecraft investigations have revealed that most planets, and some moons, have or had a global magnetic field. Generated by internal dynamos, magnetic fields are one of the few remote sensing means of constraining the properties of planetary interiors. For the Earth, its magnetic field has been speculated to be partially responsible for its habitability, and knowledge of an extrasolar planet’s magnetic field may be necessary to assess its habitability. The radio emission from Jupiter and other solar system planets is produced by an electron cyclotron maser, and detections of extrasolar planetary electron cyclotron masers will enable measurements of extrasolar planetary magnetic fields.
