LPL Evening Lecture Series

Each fall semester, the LPL Evening Lecture Series presents LPL scientists discussing their latest scientific research and space mission projects. Lectures (including time for Q&A) are held on Wednesday evenings, 7:00 to 8:00 p.m., in The University of Arizona Kuiper Space Sciences Lecture Hall, Room 308. Doors open at 6:30 p.m. Note: Food and drinks are not permitted in the lecture hall. All lectures are free and open to the community. Parking in university surface parking lots is free after 5 p.m. Please be careful not to park in service or reserved spaces. Metered street parking is also available at no cost after 5 p.m. Parking in the Cherry Avenue Garage is available after 5 p.m. at a cost of $1.00 per hour. A campus parking map is available here. Podcasts of the LPL Evening Lectures are available on UA iTunesU.

A Comet Approaches Mars

Abstract:
Comet Siding Spring will pass by Mars on Oct 19, 2014 at a distance of about 84,000 miles. The comet will zoom by Mars at the incredible speed of 126,000 mph and the atmosphere of Mars will be bombarded by gas molecules and dust in the comet's coma, depositing significant amounts of energy and mass into the Martian atmosphere. NASA and ESA (the European Space Agency) are currently operating spacecraft in orbit around Mars. In particular, the MAVEN spacecraft, launch last November, will arrive at Mars on September 21, 2014. These assets are well positioned to study comet Siding Spring and its effect on Mars. I will review what observations will be made and what we might learn about comets and Mars.

Doors open at 6:30 p.m. All lectures are free and open to the community. Parking in university surface parking lots is free after 5 p.m. Please be careful not to park in service or reserved spaces. Metered street parking is also available at no cost after 5 p.m. Parking in the Cherry Avenue Garage is available after 5 p.m. at a cost of $1.00 per hour. A campus parking map is available here.

The Big Boundary

Our Sun is embedded in a very thin hot medium of gas that is moving at ~25 km/sec with respect to it. A portion of this interstellar medium is composed of charged particles that interact with the solar wind to form a massive interaction region at a distance three times greater than that of Pluto. In this talk we'll discuss the characteristics of the solar wind and interstellar plasma, how we believe they interact, and some of the ways we have tried to measure the interaction with spacecraft and from the Earth.

Doors open at 6:30 p.m. All lectures are free and open to the community. Parking in university surface parking lots is free after 5 p.m. Please be careful not to park in service or reserved spaces. Metered street parking is also available at no cost after 5 p.m. Parking in the Cherry Avenue Garage is available after 5 p.m. at a cost of $1.00 per hour. A campus parking map is available here.

Imaging Exoplanets

It is now possible to directly detect and image planets around other stars. This presentation will describe the instruments and techniques used to separate planet light from starlight and discuss some of the recent and exciting discoveries that have been made.
