Seventh 2016-2017 meeting of the
National Capital Section of the Optical Society of America
Tuesday, May 23rd, 2017, 5:30 PM
At the NASA/Goddard Visitors Center, ICESat Road, Greenbelt, MD
Speaker: Dr. Joseph Nuth, NASA
Goddard Space Flight Center
“Planetary Defense, Impact Hazards, & OSIRIS Rex”
Human civilization has come a long way since realizing that comets and asteroids posed a threat that has previously caused major extinction events on the Earth: that an asteroid impact was the probable cause for the extinction of the dinosaurs was a shock to many earth scientists in 1980 who firmly believed that forces outside the Earth had virtually no effect on terrestrial evolution. Since then the number of known asteroids has increased from ~5000 to more than 700,000 thanks to dedicated search efforts: these are tracked and their orbits are projected well into the future to search for potential threats. Following a brief overview of the OSIRIS-REx mission and its role in Planetary Defense, this presentation will focus on steps that might be followed if an imminent impact hazard were detected and how our potential actions are constrained by the time available before impact. Implications of this very serious dependence on time for future priorities in the Planetary Defense Program will then be discussed.
Joe Nuth came to Goddard Space Flight Center in the summer of 1975 as a student intern in the Astrochemistry Branch (691) after receiving B.S. degrees in Astronomy and Chemistry from the University of Maryland. He continued studies at the University of Maryland and research at GSFC receiving a M.S. in Geochemistry (1977) and Ph.D. in Chemistry (1982) based partly on this research. He won a NAS/NRC Fellowship (1981) to study the formation and properties of dust in stellar environments and spent a year (1984) as a NAS/NRC Research Management Associate at NASA Headquarters before returning to 691 as a contractor (1985), civil servant (1986) and Branch Head (1990-2008). He continued his association with NASA HQ as the Discipline Scientist for the Origins of Solar Systems (1989–1994) and for the Planetary Materials and Geochemistry (1995-6) Research Programs. He has authored more than 150 refereed publications and has been (and continues to be) involved in several proposed missions to asteroids and comets. He is currently Deputy Project Scientist for the OSIRIS-REx mission and the Senior Scientist for Primitive Bodies in the Solar System Exploration Division at GSFC.

DIRECTIONS: to NASA/Goddard Visitor Center, Greenbelt, MD
From Washington, DC:
Take the Baltimore-Washington Parkway (Rt. 295) north to Greenbelt Road (Rt. 193). Take Greenbelt Road east for approximately two miles. The main gate will be on the left at the first traffic light after Cipriano Road. Continue on to the next traffic light and turn left onto ICESat Road (formerly Soil Conservation Road). Take your first left to reach the Visitor Center.
Take the Baltimore-Washington Parkway (Route 295) South to the Beltsville Agricultural Research Center. Exit at Powder Mill road, turn left and go under the bridge. Turn right at the first traffic light and go about 3 miles to Goodluck Road and turn right when you reach Greenbelt Road. Take your first right at ICESat Road, which is what this section of what was Soil Conservation road is now called. Take your first left to reach the Visitors Center.

Dr. George Carruthers, right, and William Conway, a project manager at the Naval Research Laboratory, examine the gold-plated ultraviolet camera/spectrograph, the first moon-based observatory that Carruthers developed for the Apollo 16 mission. Apollo 16 astronauts placed the observatory on the moon in April 1972
