Dr. Briony Horgan - Roving Mars: NASA's search for ancient life with the Perseverance rover

Briony Horgan is an Associate Professor of Planetary Science. Her research program uses data from NASA satellites and rovers, along with lab and field work back on Earth, to understand the surface processes that have shaped Mars and the Moon. She is particularly interested in using mineralogy to investigate weathering and past surface environments on Mars, as well as volcanic, sedimentary, and impact processes on both planets. Briony is a Participating Scientist on NASA's Mars Science Laboratory rover mission and a Co-I on NASAs upcoming Mars 2020 rover mission, the first step toward Mars Sample Return.

The past 30 years of exploration by NASA rovers and satellites has shown that Mars was once an Earth-like world that could have supported life. Now the Perseverance rover is taking the next big step to look for signs of ancient microbial life, through exploration of an ancient lake environment and collection of samples for eventual return to Earth.  These samples and the Perseverance rover will also help us answer big questions about how planets like Earth and Mars evolve over billions of years.  In this talk, Prof. Horgan will give an overview of the Perseverance mission so far and how we're planning on getting the samples back.
Brian Murphy - Remote Astronomical Observations for All!

For many of us our love of astronomy began with our first view through a telescope at celestial gems such as Saturn and the Moon.   Though most still enjoy being at the eyepiece, in the last 20 years observational astronomy has undergone a revolution in that most research astronomy is now done remotely.   Since 2008 Butler University has been part of the Southeastern Association for Research in Astronomy (SARA) telescope consortium.  The SARA consortium presently consists of 12 universities that have pooled their resources to refurbish and run remotely three 1-meter class telescopes located all located at superb observing sites: Kitt Peak, Arizona, Cerro Tololo, Chile, and the Canary Islands off the coast of Morocco.  These telescopes allow Butler astronomers (and occasionally the public) to observe both the northern and southern celestial hemispheres.  Besides the SARA observatories out on-campus 38-inch Holcomb Telescope can also be operated remotely.   But remote observing need not be limited to research. Remote observing allows observers at all levels (and the public) to observe/view objects that may be unseen due to light pollution or location in detail the human eye would never be able to reveal.   In this talk I will give a review of remote astronomy and how it is done along with a few examples of what we have done at Butler.  And if technology permits, we will actually do remote observing during this talk (live).
