In commemoration of the 50th anniversary of
human space travel the audience will receive
an overview of the history of space flight
from the fantastic dreams of writers to the
ubiquity of space in our daily lives.
Included will be the historic roots,
triumphs and tragedies, and some of the
often overlooked challenges to making space
flight real. Dave supplements his interests sharing his expertise working as technology implementer at the Tredyffrin/Easttown School District. |

How will astronauts endure extended missions? What medical implications are there for traveling to the moon, the planets, and possibly other star systems? With Dr. Friedman's combined background as a medical doctor and the president of our society, he can give us a unique perspective of what future space travelers will have to contend with physically and medically. |

(past RAS member and educator/producer at the Fels Planetarium) will
join us for a retrospective review of Armand Spitz (past RAS

planetariums manufactured here in Pennsylvania. Armand Spitz has
long since passed away but his legacy lives on. Learn how planetaria
evolved as Armand attempted to make these facilities affordable to many
schools and museums. Joyce will talk about the evolution of the
instrument into what is considered "state-of-the-art"
today. |
