Solar Sail Propulsion by 2050: An Enabling Capability for Heliophysics Missions
Les Johnson, Nathan Barnes, Matteo Ceriotti +11
Solar sails enable missions to observe the solar environment from unique vantage points, such as sustained observations away from the Sun-Earth line; sub-L1 station keeping; high i…
Long-baseline horizontal radio-frequency transmission through polar ice
P. Allison, S. Archambault, J. J. Beatty +63
We report on analysis of englacial radio-frequency (RF) pulser data received over horizontal baselines of 1--5 km, based on broadcasts from two sets of transmitters deployed to dep…
Recognizing the Value of the Solar Gravitational Lens for Direct Multipixel Imaging and Spectroscopy of an Exoplanet
Slava G. Turyshev, Michael Shao, Janice Shen +18
The Solar Gravitational Lens (SGL) allows for major brightness amplification ( at wavelength of m) and extreme angular resolution ( arcsec) within…
Measurement of the real dielectric permittivity epsilon_r of glacial ice
P. Allison, S. Archambault, J. Auffenberg +66
Using data collected by the Askaryan Radio Array (ARA) experiment at the South Pole, we have used long-baseline propagation of radio-frequency signals to extract information on the…
