Mark Matney (NASA) is in Florence at CNR and will go to Rome to visit Alessandra Celletti and deliver a seminar at Tor Vergata on the 3rd of July.

The seminar is titled "The Challenge of Orbital Debris".

Abstract: Since the beginning of space flight in 1957, humans have left a troubling legacy of garbage in space.  Discarded rocket bodies, derelict  satellites, and explosion debris now litter Earth orbit.  These debris
pose a risk to human space flight, robotic space flight, and even safety of humans on the ground.  What do we know about this environment?  What are we doing about it?  This talk will answer these questions and discuss the path for the future.
