"The Ancient Lunar Dynamo: How To Resolve the Intensity and Duration Conundrums"

Sabine Stanley

DTM Weekly Seminar Series
Sabine Stanley

Sabine Stanley, a Bloomberg distinguished professor at Johns Hopkins University, will present a lecture titled "The Ancient Lunar Dynamo: How To Resolve the Intensity and Duration Conundrums" at 11 a.m. on Thursday, April 27, 2017, in the Greenewalt Lecture Hall as part of DTM's Weekly Seminar Series.

Stanley received her Ph.D. in geophysics from Harvard University in 2004. Her research involves understanding planetary interior processes and evolution. She focuses on planetary magnetic fields, dynamo theory, interior structure models and other geophysical methods to learn about the deep interiors of planets. 

Coffee, tea, and a light breakfast will be served before the lecture at 10:30 a.m.

"Rocks from Space: Be Grateful and a Little Afraid"

Neighborhood Lecture Series

Our Broad Branch Road Spring 2017 Neighborhood Lecture Series continues with Conel M. O'D. Alexander, a staff scientist at DTM.  Alexander will present, "Rocks from Space: Be Grateful and a Little Afraid" at 6:30 p.m. on Thursday, April 27, 2017, in the Greenewalt Lecture Hall.

‘Rocks’ from space have had a profound influence on the evolution of Earth – from the giant impact that created the Moon, to the asteroids that killed off the dinosaurs and, more locally, created the Chesapeake Bay, to tiny grains that may have brought prebiotic molecules that helped kick start life on Earth. The rate at which the Earth has accreted material from space has decayed dramatically since it formed. Nevertheless, ignoring the occasional large ‘hiccup’, some 30-40 thousand tons of extraterrestrial material fall to Earth every year as meteorites and cosmic dust. This has been a boon to science, providing samples of other stars and Mars, helping to develop our picture of the timescales and conditions at the birth of our Solar System, and providing constraints for how the terrestrial planets formed. In this talk, Alexander will review where and how meteorites and cosmic dust are collected, and what they have taught us about the origin and early evolution of our Solar System.

Doors open at 6 p.m. Lecture Hall seating is first to come, first serve. Eventbrite tickets are not required, so please arrive early to reserve your seat. Eventbrite registration is encouraged to skip the sign-in process at the door.

Light refreshments will be available before the lecture at 6 p.m.

"Mars, Moons, Missions & Microbes: Life as We Don't Know It - How Do We Find It?"

Andrew Steele

Neighborhood lecture Series
Andrew Steele

Our Broad Branch Road Spring 2017 Neighborhood Lecture Series continues with Andrew Steele, a staff scientist at the Geophysical Laboratory.  Steele will present, "Mars, Moons, Missions & Microbes: Life as We Don't Know It - How Do We Find It?" at 6:30 p.m. on Thursday, May 25, 2017, in the Greenewalt Lecture Hall. 

The main focus of Steele’s research has been the development of scientific and measurement criteria for the unambiguous detection of life in early Earth and Mars samples, and future robotic and sample return missions to Mars, Europa, and Enceladus. Steele’s talk will explain how this research has evolved into a three-pronged approach to laboratory investigations using a diverse range of techniques and samples coupled with development and testing of instrumentation for future Mars missions and the characterization of data from space flight missions to Earth orbit, Mars, and comets.

Doors open at 6 p.m. Lecture Hall seating is first to come, first serve. Eventbrite tickets are not required, so please arrive early to reserve your seat. Eventbrite registration is encouraged to skip the sign-in process at the door.

Light refreshments will be served before the lecture at 6 p.m.
