The Breakthrough Starshot research program envisions a laser-propelled sail that will probe our neighboring stars within a human lifetime. Starshot spacecraft weigh no more than a few grams and are accelerated by photon momentum transfer with a beam

Seven persistent trails associated with bright reballs were probedwith asteerable Nawind/temperature lidar at Starre Optical Range, NM during the 17/18 Nov peak of the 1998 Leonid meteor shower. These chemilu- minescence trails were especially rich i

New near-infrared images of the young, nebulous, intermediate-mass (Herbig Ae/Be) star LkHα 198 using direct imaging, adaptive-optics compensated speckle imaging, and standard speckle imaging reveal complex structure in its circumstellar dust distri

Atmospheric turbulence profoundly limits the angular resolution of astronomical telescopes working at visible and near-infrared wavelengths. In fact, the angular resolution for conventional imaging through turbulence is on the order of 5{endash}20{pe

Using a stable single frequency (Δυ < 1 MHz) cw fasor we have characterized the guide star radiance under several conditions, including routinely measuring the radiance at various launch powers and simultaneously illuminating the same spot with a s

A computer-automated cw sodium guidestar FASOR (Frequency Addition Source of Optical Radiation) producing a single frequency 589-nm beam with up to 50 W for mesospheric beacon generation has been integrated with the 3.5-m telescope at the Starfire Op

Mesospheric sodium guidestar radiance is plotted vs. wavelength, fasor power, fasor polarization and date. Peak radiance for circular polarization was about 7000 photons/sec/cm 2 (V 1 magnitude = 5.1) for 30 watts of pump power in November of 2005. P
