Michael Busch and Peter Jenniskens
SETI Institute
To
celebrate 'Asteroid Day', the SETI Institute held a special event where
two SETI Institute asteroid scientists, Michael Busch and Peter
Jenniskens gave short presentations on the latest thinking on how to
handle the Near Earth Asteroid (NEA) problem and the goals of NASA's
Asteroid Return Mission (ARM).
Michael Busch will give a talk on
the properties of target NEAs and Peter Jenniskens will give a talk on a
new concept (SHEPHERD) for the Asteroid Return mission.
Characterizing Target Asteroids for ARM with Michael Busch
ARM
would go to a near-Earth asteroid, pick up a large block or boulder,
and return it to Earth-Moon space. Based on ground-based and spacecraft
observations, the ARM team has identified four candidate asteroids: 2008
EV5, Bennu, Itokawa, and 1999 JU3. I'll review what we currently know
about these objects and how we've learned it.
The SHEPHERD Asteroid Return Mission with Peter Jenniskens
The
current ARM is focussed on collecting a boulder from a large asteroid,
in part because small free-floating asteroids are hard to characterize
in advance well enough to give engineers certainty that they can handle
the rock. Future asteroid utilization missions will face the same issue.
Now, Peter Jenniskens, working with Bruce Damer, Stuart Pilorz, Julian
Nott, and other colleagues, has proposed a way to get around that
difficulty, and in the process they created a new vision for future
space exploration.
