A Deep and Wide Twilight Survey for Asteroids Interior to Earth and Venus

Scott S. Sheppard, David Tholen, Petr Pokorny +17

We are conducting a survey using twilight time on the Dark Energy Camera with the Blanco 4m telescope in Chile to look for objects interior to Earth's and Venus' orbits. To date we…

Exogenous delivery of water to Mercury

Kateryna Frantseva, David Nesvorný, Michael Mueller +3

Radar and spacecraft observations show the permanently shadowed regions around Mercury's North Pole to contain water ice and complex organic material. One possible source of this m…

Modeling Meteoroid Impacts on the Juno spacecraft

Petr Pokorný, Jamey R. Szalay, Mihály Horányi +1

Events which meet certain criteria from star tracker images onboard the Juno spacecraft have been proposed to be due to interplanetary dust particle impacts on its solar arrays. Th…

Collisional Evolution of the Inner Zodiacal Cloud

J. R. Szalay, P. Pokorny, D. M. Malaspina +9

The zodiacal cloud is one of the largest structures in the solar system and strongly governed by meteoroid collisions near the Sun. Collisional erosion occurs throughout the zodiac…

A Deep Search for Stable Venus Co-Orbital Asteroids: Limits on The Population

Petr Pokorny, Marc J. Kuchner, Scott S. Sheppard

A stable population of objects co-orbiting with Venus was recently hypothesized in order to explain the existence of Venus's co-orbital dust ring. We conducted a 5 day twilight sur…

Precision measurements of radar transverse scattering speeds from meteor phase characteristics

Michael Mazur, Petr Pokorny, Peter Brown +5

We describe an improved technique for using the backscattered phase from meteor radar echo measurements just prior to the specular point () to calculate meteor speeds and th…
